|
[
"Disseminated intravascular coagulation",
"Hemophilia A",
"Severe liver disease",
"Vitamin K deficiency"
] |
A
|
This is a description of disseminated intravascular coagulation (DIC), a feared and often lifethreatening complication of many other disorders, including amniotic fluid embolism, infections (particularly gram negative sepsis), malignancy, and major trauma. This is suspected when a decrease in platelets and a prolongation of PT and PTT times are observed. The observed hematologic abnormalities are caused by consumption of platelets and clotting factors, caused by extensive microclot formation with accompanying fibrinolysis (reflected by the increased fibrin split products).
Hemophilia (choice B) alters the PTT without affecting the other indices.
Severe liver disease (choice C) produces alterations comparable to those in vitamin K deficiency; platelets can also be decreased secondary to a generalized metabolic marrow dysfunction, but fibrin split products would not be increased.
Vitamin K deficiency (choice D) is associated with alterations in PT and PTT, but platelets will not be decreased, nor will fibrin split products be increased.
Von Willebrand's disease (choice E) produces impaired platelet adhesion and increases the bleeding time and the PTT, but will not produce the other features described.

Abhishek starts to paint a fence on one day. On the second day, two more friends of Abhishek join him. On the third day 3 more friends of him join him and so on. If the fence is completely painted this way in exactly 20 days, then find the number of days in which 10 girls painting together can paint the fence completely, given that every girl can paint twice as fast as Abhishek and his friends(Boys)? (Assume that the friends of Abhishek are all boys).

Number of men working on first day = 1
Number of men working on second day = 3
Number of men working on second day = 6 and so on..
Total number of boys till the end of the work = [n(n + 1) (n + 2)] / 6
= [20 x 21 x 22] / 6 = 1540
Given that every girl paints twice as fast as Abhishek’s friends.
Hence, 20 girls work is being done.
Thus, the number of days taken to paint the fence = 1540/20 = 77.

A woman baked bread for members of her family and an extra one for a hungry passer-by. She kept the extra bread on the window-sill , for whomever would take it away. Every day, a hunch-back came and took away the bread. Instead of expressing thanks, he said the following words as he went his way: "The evil you do remains with you. The good you do, comes back to you!" This went on, day after day. Every day, the hunch-back came, picked up the bread and repeated the words. One day, the woman felt angry and decided to do away with him. She added poison to the bread she prepared for him !As she was about to place it on the window sill, her hands trembled. "What is this I am doing?" she thought...As usual, the hunch-back came, picked up the bread and repeated those words. That evening, there was a knock on the door. As usual, the hunch-back came, picked up the bread and repeated those words. That evening, there was a knock on the door. As she opened it, she was surprised to find her son standing in the doorway. His clothes were torn. He was hungry, starved and weak. As he saw his mother, he said, "Mom ,it's a wonder I'm here. While I was but a mile away, I was so hungry that I fell down. I would have died, but just then an old hunch-back passed by. I begged of him for a small part of his food, and he was kind enough to give me a whole bread. As the mother heard those words, her face turned pale and red. She remembered the poisoned bread that she had made that morning. Had she not burnt it in the fire, it would have been eaten by her own son, and he would have lost his life! It was then that she realized the significance of the words: "The evil you do remains with you. The good you do,comes back to you!" What happened to the son on his way back home?

How do genes located on separate nonhomologous chromosomes sort?
|
[

] |
A
|
Linked Genes Violate the Law of Independent Assortment Although all of Mendel’s pea characteristics behaved according to the law of independent assortment, we now know that some allele combinations are not inherited independently of each other. Genes that are located on separate nonhomologous chromosomes will always sort independently. However, each chromosome contains hundreds or thousands of genes, organized linearly on chromosomes like beads on a string. The segregation of alleles into gametes can be influenced by linkage, in which genes that are located physically close to each other on the same chromosome are more likely to be inherited as a pair. However, because of the process of recombination, or “crossover,” it is possible for two genes on the same chromosome to behave independently, or as if they are not linked. To understand this, let’s consider the biological basis of gene linkage and recombination. Homologous chromosomes possess the same genes in the same linear order. The alleles may differ on homologous chromosome pairs, but the genes to which they correspond do not. In preparation for the first division of meiosis, homologous chromosomes replicate and synapse. Like genes on the homologs align with each other. At this stage, segments of homologous chromosomes exchange linear segments of genetic material (Figure 12.18). This process is called recombination, or crossover, and it is a common genetic process. Because the genes are aligned during recombination, the gene order is not altered. Instead, the result of recombination is that maternal and paternal alleles are combined onto the same chromosome. Across a given chromosome, several recombination events may occur, causing extensive shuffling of alleles.

Health experts have discovered that adding low-calorie vegetable soup to the start of a meal can actually help to lose weight. Because you feel full sooner, you eat less of your main course. The soup regime was tested by researchers at Pennsylvania State University, led by Dr Barbara Rolls. They found that when people ate a first course of soup before lunch they reduced their total calorie intake by 20 per cent, compared with those who did not begin the meal with soup. But those who _ creamy soups should be careful.Researchers stressed the soup must be low-calorie and based on stock , not cream. All of the soups tested in the study were made from identical ingredients - chicken stock , broccoli , potato, cauliflower and carrots. They were mixed together to create four different textures and thickness from separate stock and vegetables through to pureed soup. Scientists thought that thick soups with chunks of vegetables which required chewing might be more filling, but to their surprise they found all forms had the same effect. The findings were presented to the Experimental Biology conference in Washington, DC, and the research was part-funded by the National Institutes of Health. Which of the following can not be in the low-calorie soup?

We are not born doubting ourselves. We learn to do it. In fact, we are usually taught to doubt ourselves. We can learn some ways that allow us to become more accepting of ourselves. Following are two behaviors that might explain the reasons why you can't move towards greater self-acceptance. One thing that might cause you not to accept yourself is over-generalizing about something you've done that you don't like.For example, if you fail a test you might generalize and say, "I'm really a stupid person." When you do this you are making a statement about all of you all of the time and not just about this one situation at this time. Instead, you might decide that your grade on this test in this subject at this time was indeed poor, and then go on to decide what you want to do about your poor grade, if anything. Getting stuck in over-generalizing discourages you from taking steps that might allow you to do better on the next exam and to build an expectation of future failure. Having standards that are impossibly high is a second way you can not accept yourself. It may not come as a surprise to you that most of us are more demanding of ourselves than we are of others. Somehow we can tolerate the fact that other people fail, that they aren't always kind, that they've done things they aren't proud of, but we have difficulty accepting those very human aspects of ourselves. The need to be perfect is another way to set yourself up for failure and enhance the feeling that you are not acceptable. We all make mistakes. Accepting less than perfection simply means recognizing the limitations natural in being born a human being. Learn to value who you are rather than who you could become. Wouldn't it be overpowering if we always had to do what we imagine we could do? Nobody has the time and energy to do all of that. We must make choices about what we will pursue and do them the best we can under the circumstances, which aren't always ideal, by the way. What is the author's attitude according to the passage?
|
[
"It's necessary for people to be perfect.",
"It's acceptable for people to be imperfect.",
"It's strange for people to be born with limitation.",
"It's possible for people to do what they imagine."

What percent of the different arrangements of the letters of the word ABACUS are those in which the vowels appear together?
|
[
"10%",

] |
B
|
The total number of different arrangements are 6!/2=360. We divide here by 2, since we have two same letters A.
Letters A, A, and U are vowels. Put them together and consider as one object. So, we have 4 different objects (AAU) B C S. The number of different arrangements of them are 4!=24. And we have 3 possibilities to arrange vowels: AAU, AUA, UAA. Therefore, we have 24*3=72 different arrangements.
Hence, 72/360*100%=20%.

In the Western world in-laws usually don't get along well with each other or with a new spouse . Perhaps they have a problem in understanding that their wonderful child has now grown up and got married. Maybe they don't like the spouse their child picked. Or maybe they just don't think that anyone will ever be good enough for their own "baby". So what can the newly married people do? First of all, go for a long honeymoon. This will give you two things. First, it will give you time to get close to your new partner. Now you must stay with him or her just as you said on your wedding day. Second, it will give the in-laws time to cool down after the exciting wedding. Enjoy your honeymoon! When you return, it will be time to start dealing with the rest of the family. After you get back from your honeymoon, move to another place. Do whatever you need to do. Change your job. Start a new career, and so on. If you stay near your home or move into a house just down the street from either family, you'll get in trouble. Trust me! You also need to start making new family traditions. You don't have to make your mum's apple pie for Thanksgiving. You don't have to go to both families on Christmas Eve! Relax. You don't have to have both soon-to-be grandmothers with you when you are giving birth! Don't give in to in-law pressure. Finally, talk with other new spouses.

Lymph that collects in tissues slowly passes into tiny lymph vessels. Lymph then travels from smaller to larger lymph vessels. Muscles around the lymph vessels contract and squeeze the lymph through the vessels. The lymph vessels also contract to help move the lymph along. Eventually, lymph reaches the main lymph vessels, which are located in the chest. From these vessels, lymph drains into two large veins of the cardiovascular system. This is how lymph returns to the blood.

Aldehydes and ketones can work weak hydrogen bonds with water through what atom?
|
[
"basalt oxygen atom",
"carbonyl oxygen atom",
"carbon carbon atom",
"pyridinium oxygen atom"
] |
B
|
Aldehydes and ketones can work weak hydrogen bonds with water through the carbonyl oxygen atom. The lower members of both series (3 carbons or fewer) are soluble in water in all proportions. As the length of the carbon chain increases, water solubility decreases. Similar to ethers, neither aldehydes nor ketones can hydrogen bond with themselves. As a result, their boiling points are generally lower than those of alcohols. Unlike alkanes however, aldehydes and ketones are polar molecules due to the more electronegative oxygen atom. The dipole-dipole interactions are stronger than the dispersion forces present in alkanes. The boiling points of aldehydes and ketones are intermediate between those of alkanes and alcohols. For example, the boiling point of ethane is -89°C, ethanal is 20°C, and ethanol is 78°C.

The hole in the Earth's ozone layer has until now protected Antarctic from the worst effects of global warming, but scientists have warned that as the hole closes up in the next few decades, temperatures on the continent could rise by around 3degC on average, with melting ice contributing to a global sea level increase of up to 1.4 meters. In the past decades the western Antarctic has seen rapid ice loss as the world has warmed, but the other parts of the continent have, , been cooling, resulting in a 10% increase in ice in the seas around the region. This is because the hole in the ozone layer has increased cold winds in Antarctic, making much of the continent surface colder than usual. But now that the gases that cause the ozone hole have been banned, scientists expect the hole to repair itself within the next 50 to 60 years. By then the cooling effect will have faded out and the Antarctic will face the full impact of global warming. This means an increase in average air temperatures of around 3degC and a reduction in sea ice by around a third. The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who monitors Antarctic ice sheets, said, "The ice sheets in Antarctic are hundreds of meters thick. But once warm ocean waters start flowing underneath, the ice will begin thinning and could break up very quickly." Thinning ice sheets cause ice to break away from the continent and to melt even faster. Escaping ice from western Antarctic has already resulted in a 10% rise in global sea level in recent decades. Johnson believes that international action to reduce global warming is required immediately or it may be too late. "Everything is connected----Antarctic may be a long way away but it is an important part of the Earth's system," said Johnson. "It contains 90% of the world's ice, 70% of the world's fresh water and that is enough, if it melts completely, to raise sea levels by 63 meters." Even in a worse-case situation scientists don't expect the ice to entirely disappear, but predict that, because of the melting ice sheets, average sea level rise will be around 1.4 meters higher by the end of the century. What is the effect of the hole in the ozone layer on Antarctic?

The education of thousands of children with reading and sight trouble is being held back because of a lack of awareness of their legal rights, say campaigners. They are calling for greater efforts to increase awareness of the rights of such children to have text books in design other than standard print. The campaign is being supported by five times Olympic gold medalist, Sir Steve Redgrave, who has reading trouble. Pupils have the right to receive text in another way, and parents can take action under the Disability Discrimination Act (DDA) if they feel their children are being treated in a different way through a lack of support. But new research suggests 89 per cent of print disabled pupils and their parents are unaware of software which changes standard print into other substitutes like combined text and audio files which can be read or listened to. Sir Steve has teamed up with software company Dolphin Computer Access to raise awareness of software turning tools. He said: "I recognize that schools have competing priorities for their resources , but I would like to see a much greater effort on the part of the government and schools to raise awareness among parents that these additional solutions exist and that their children have a right to use them." Mike Foster, Dolphin's local MP in Worcester, is _ the campaign. "There is clearly an issue to solve concerning software for special needs. I'll be asking ministers what steps can be taken to improve the situation", he said. What is the best title of this text?

I hope you are familiar with basic probability fundas -
Let's say you have just ONE letter and TWO envelopes ONE of which is correctly addressed and the other addressed incorrectly.
What's the probability of putting the Letter in the correctly addressed envelope -
To answer this question - we see IN HOW MANY WAYS can the letter be put into the envelope - you could put it (assuming you don't know which envelope is which) in either of the two - so in total you have TWO ways of shoving the letter in. However, there's only ONE way in which it can go into the correctly addressed envelope -
so 1/2 is the prob of putting in correct envelope. This is easy.
Now in our current problem - let's say we have just ONE letter but FOUR envelopes. Only one of these envelopes has the address corresponding to the letter. The remaining three envelopes are incorrectly addressed.
So the probability that you will put the letter correctly is 1/4. Right?
What happens if i ask you the reverse question? what is the prob for putting it in the incorrect envelope. Suddenly you have three envs that are incorrect so you can put the letter incorrectly with a prob of 3/4. Right?
The whole problem can be broken down into Four Events that will fulfill the requirement of the question
Event 1 - E1
We know that prob of putting ONE Letter correctly is 1/4. Now once ONE letter has been put CORRECTLY, what are you LEFT with? You are left with THREE ENVELOPES and the remaining THREE letters. Since the one letter has been put correctly (though technically we have just calculated the PROBABILITY that the first letter goes into the correct envelope) we have the remaining THREE Letters and THREE envelopes.
Event 2 - E2
Let's take letter number 2 now - what is the probability that it LANDS in the INCORRECT envelope. Again by the same logic as above - there are 3 envelopes remaining out of which ONLY ONE has the correct address for LETTER number 2. The remaining 2 have INCORRECT address and LETTER NUMBER 2 could go in either of these 2 to meet our condition.
Thus the probability of this event is 2/3
So till now what we have done is -
we have calculated the prob of shoving Letter number 1 in correct env -- 1/4
we have calculated the prob of shoving Letter number 2 in INcorrect env --- 2/3
Event 3 - E3
Now let's take letter number 3 - again according to question we want to shove this in the WRONG envelope. There are 2 remaining envelopes and hence the prob of shoving this in the wrong env (or equally in the RIght env) is 1/2.
Finally we come to event E4 - the Letter number 4. This has only one way of going in so its probability of being put into the WRONG envelope is 1.
ok so we can see that our grand event is actually a combination of FOUR EVENTS happening - each with a probability of its own. So to calculate the total probability of the Grand Event itself we just multiply the individual probabilities since each event happens INDEPENDENTLY of each other
Egrand = 1/4 * 2/3 * 1/2 * 1/1 = 1/12
However at this point - I must introduce one last element in this question -since there are FOUR Letters - what we saw above was JUST ONE SEQUENCE of events leading to the desired result.
If we arbitrarily call the letters L1 thru L4, and let's say the above was an example in which we started by Picking up Letter L1 and worked thru the remaining letters, we could have equally well started out with letter L2 or L3 or L4.
Thus since each of these events ARE MUTUALLY EXCLUSIVE, meaning THEY CAN NEVER HAPPEN ALL THE SAME TIME BUT ONLY ONE LETTER AT A TIME, to calculate the TOTAL PROBABILITY of we will add the individual probabilities 1/12 + 1/12 + 1/12 + 1/12 which works out to 1/4.

We all, at one time or another, have pretended to be a rock star, singing and dancing along to our favorite song. Most of us have done this in the privacy of our own room when we were kids and as adults, in the privacy of our homes. Me? I love to do that when I drive! I turn on the radio, find a song that I can sing along too and pretty soon my arms are in the air and I am moving along to the rhythm. Most of the time, I do this on my way to work. Yes, that is true, I will be in my nice work clothes, jamming while driving or stopped at a traffic light I get weird looks from some people and others laugh. Personally, I love to get lost in the rhythm of a song which leads me to share with you the importance of being silly! The definition for the word silly, according to the dictionary is: stupid, foolish and nonsensical. I know many people do not want to look foolish. So they walk around all serious, which in all honesty, is foolish! No one is perfect, I repeat: no one is perfect. I don't care how educated, how thin, how beautiful, how simple, how frugal , how rich, and so on...No one is perfect! So why pretend to be something you are not? Life is so short. You never know when this beautiful journey will be over, so why waste a single second on being so full of rigidity ? Here is a quote by Souza, that I think says it all and is a great recipe for life: "Dance as though no one is watching you, Love as though you have never been hurt before, Sing as though no one can hear you, Live as though heaven is on earth." When we were kids, we had no idea of what limitations were and we had no care in the world so we could do things without worrying about how we appeared to others. However, as we grew up, we lost that childlike innocence. So don't lose the child that still lives within you. The next time you feel down, go turn on your favorite song, and sing and dance along like there is no tomorrow or watch something that makes you laugh. Laughter is the best medicine to whatever ails (......) you and nothing is better than laughing so hard that your stomach hurts. Trust me, you will feel a whole lot better, and who doesn't want to feel good? Which of the following would be the best title for the text?

What is the difference between a college and a university? This is a good question for students who want to attend a college or a university in the United States. Colleges and universities have many things in common. Both provide a greater understanding of the world and its past. Both provide education in the arts and sciences. And both can help prepare young people to earn a living. Students who complete their undergraduate studies either at a four-year college or a university receive a bachelor's degree. One difference is that many colleges do not offer graduate studies. Universities are generally bigger, offer more programs and do more research. Modern universities developed from those of the Middle Ages in Europe. The word "university" comes from the Latin "universitas". This described a group of people organized for a common purpose. The word "college" comes from a Latin word with a similar meaning, "collegium". In England, colleges were formed to provide students with places to live in. Usually each group of students was studying the same thing. So college came to mean an area of study. But a college can also be a part of a university. The first American universities divided their studies into a number of areas and called each one a college. This is still true. Programs in higher learning may also be called schools. The University of Arizona in Tucson, for example, has 18 colleges and 10 schools. They include the colleges of pharmacy , education, engineering and law. They also include the schools of architecture, dance and public administration. College is also used as a general term for higher education. A news report might talk about "college students" even if they include students at universities. Or someone might ask, "Where do you go to college?" Today, most American colleges offer an area of study called liberal arts. These are subjects first developed and taught in ancient Greece. They include language, philosophy and mathematics. The purpose is to train a person's mind instead of teaching job skills. When the term "college students" appears in a newspaper, it may refer to _ .

Planning for the weather No matter what time of year you vacation in San Diego, be sure to bring a light jacket or sweater and bring shorts. During our summer months, we have warm days but cool evenings, especially if you are near the ocean. Those cool evenings can feel cold and fresh if you are visiting from someplace that is typically hot and damp all summer. And during our winter months, we can have days that reach 80 degrees Fahrenheit (27 degrees Celsius). In fact, our winter months are the sunniest months of the year along the San Diego coast. How to get around San Diego Deciding whether you need to rent a car for your visit to San Diego? If you are planning to visit attractions in and around downtown San Diego, including SeaWorld, San Diego Zoo, Balboa Park, Old Town, Coronado, and the Gaslamp Quarter, all of these attractions can be readily accessed by public transportation assuming the hotel or place you are staying in is close to a bus or trolley stop. Tour guests comment on how easy it is to use our transportation system, how clean it is, and the low cost for a one-day or multi-day pass that works on both buses and trolleys. However, if you are going to visit attractions further away from downtown San Diego such as the Safari Park or Legoland or if you want to visit our local mountains or desert, we recommend a car rental. How to make time for all the things to do Our final tip for now is to plan ahead. Unlike most cities where there may be a few concentrated tourist areas and it's easy to find things as you go, San Diego offers hundreds of attractions and guests tell us they are overwhelmed and certainly didn't plan enough time once they find how much there is to do in San Diego. Many guests visit San Diego as part of an extended trip that includes San Francisco and Los Angeles. They often plan fewer days in San Diego because they assume it is the smallest city with the least to offer only to say they wished they had planned more days in San Diego because it offers more things to do in a much more relaxing environment. By planning ahead you can also get discounts for various attractions. For example you can save a lot of money at SeaWorld if you buy your tickets in advance online, at a visitor center or through your hotel. Another reason to plan ahead is that some attractions close early or get sold out since San Diego is a big destination for major conventions and big companies bringing in employees from around the world for special events in beautiful, sunny San Diego. You'd better rent a car if you are to visit .

United States President George W. Bush is expected to issue a directive in the next few weeks. It will give the US Air Force a green light for the development of space weapons, US media reported last week. This would potentially start a new global arms race, some experts have warned. To keep that from happening, last Wednesday the White House explained that it was not considering putting weapons in space. It said it was making a shift in US space policy to allow for protection of satellites. But some defense analysts and arms control advocates argue that the policy will pave the way for the US to put both defensive and offensive weapons in space. "No one should be fooled," said Theresa Hitchens, an American weapons expert. The US is now restricted by a 1996 directive signed by President Bill Clinton. Plans for space weapons were vetoed by the Clinton cabinet. The directive emphasized the peaceful use of space , in agreement with almost unanimous global opinion. The US military has placed importance on space and has sent up numberous satellites for troop communications and to provide intelligence and data to guide bombs to their targets. The US Air Force wants to develop space- based weapons that could strike targets anywhere in the world within 90 minutes of receiving the order to open fire. These new weapons under development cover a wide range. They include hunter- killer satellites and orbiting weapons. And they use lasers, radio waves, or even dense metal tubes, known as " Rods from God", dropped from space to do the damage. There are many barriers to the setting up of this kind of program, experts say. First is the coast. It is estimated that the budget may be US $220 billion to US $ 1 trillion . The technical difficulties of developing reliable space weapons are also a problem. And, the program will draw strong criticism from around the world. Experts worry about starting a space arms race.

The replicative cycle of chlamydiae involves two forms of the organism (biphasic): a small, hardy infectious form termed the elementary body (EB), and a larger fragile intracellular replicative form termed the reticulate body (RB). The EB is a metabolically ine form that neither expends energy nor synthesizes protein. It enters the cell in an endocytotic vacuole and begins the process of conveing to the replicative RB. The ability to inhibit lysosomal fusion is unique to chlamydia and enables the EB to survive in a vesicle referred to as an inclusion. C trachomatis also inhibits apoptosis of epithelial cells, thus enabling completion of its replicative cycle. Ref: Ray C.G., Ryan K.J. (2010). Chapter 39. Chlamydia. In C.G. Ray, K.J.

Factors of 30 are: 1, 2, 3, 5, 6, 10, 15, and 30.
I. wb + b^2 --> if w=1 and b=2 then wb + b^2=6, which is a factor of 30. OK;
II. (w + b)^2 --> (w + b)^2 is a perfect square, no perfect square (but 1) is a factor of 30. DISCARD;
III. w + b --> if w=1 and b=2 then w + b=3, which is a factor of 30. OK.

The loss of too much blood may lead to shock of what system?
|
[
"nervous",
"circulatory",

"Circular"
] |
B
|
Circulatory Shock The loss of too much blood may lead to circulatory shock, a life-threatening condition in which the circulatory system is unable to maintain blood flow to adequately supply sufficient oxygen and other nutrients to the tissues to maintain cellular metabolism. It should not be confused with emotional or psychological shock. Typically, the patient in circulatory shock will demonstrate an increased heart rate but decreased blood pressure, but there are cases in which blood pressure will remain normal. Urine output will fall dramatically, and the patient may appear confused or lose consciousness. Urine output less than 1 mL/kg body weight/hour is cause for concern. Unfortunately, shock is an example of a positive-feedback loop that, if uncorrected, may lead to the death of the patient. There are several recognized forms of shock: • Hypovolemic shock in adults is typically caused by hemorrhage, although in children it may be caused by fluid losses related to severe vomiting or diarrhea. Other causes for hypovolemic shock include extensive burns, exposure to some toxins, and excessive urine loss related to diabetes insipidus or ketoacidosis. Typically, patients present with a rapid, almost tachycardic heart rate; a weak pulse often described as “thread;” cool, clammy skin, particularly in the extremities, due to restricted peripheral blood flow; rapid, shallow breathing; hypothermia; thirst; and dry mouth. Treatments generally involve providing intravenous fluids to restore the patient to normal function and various drugs such as dopamine, epinephrine, and norepinephrine to raise blood pressure. • Cardiogenic shock results from the inability of the heart to maintain cardiac output. Most often, it results from a myocardial infarction (heart attack), but it may also be caused by arrhythmias, valve disorders, cardiomyopathies, cardiac failure, or simply insufficient flow of blood through the cardiac vessels. Treatment involves repairing the damage to the heart or its vessels to resolve the underlying cause, rather than treating cardiogenic shock directly.

What is the year next to 1990 which will have the same calendar as that of the year 1990?
|
[
"1992",
"2001",
"1996",
"None of these"
] |
B
|
Explanation :
For a year to have the same calendar with 1990 ,total odd days from 1990 should be 0.
Take the year 1992 from the given choices.
Total odd days in the period 1990-1991= 2 normal years
≡ 2 x 1 = 2 odd days
Take the year 1995 from the given choices.
Number of odd days in the period 1990-1994 = 4 normal years + 1 leap year
≡ 4 x 1 + 1 x 2 = 6 odd days
Take the year 1996 from the given choices.
Number of odd days in the period 1990-1995= 5 normal years + 1 leap year
≡ 5 x 1 + 1 x 2 = 7 odd days ≡ 0 odd days
(As we can reduce multiples of 7 from odd days which will not change anything)
Though number of odd days in the period 1990-1995 is 0, there is a catch here.
1990 is not a leap year whereas 1996 is a leap year.
Hence calendar for 1990 and 1996 will never be the same.
Take the year 2001 from the given choices.
Number of odd days in the period 1990-2000= 8 normal years + 3 leap years
≡ 8 x 1 + 3 x 2 = 14 odd days ≡ 0 odd days
Also, both 1990 and 2001 are normal years.
Hence 1990 will have the same calendar as that of 2001

Next, we identify the least precise measurement: 13.7 kg. This measurement is expressed to the 0.1 decimal place, so our final answer must also be expressed to the 0.1 decimal place. Thus, the answer is rounded to the tenths place, giving us 15.2 kg. Significant Figures in this Text In this text, most numbers are assumed to have three significant figures. Furthermore, consistent numbers of significant figures are used in all worked examples. You will note that an answer given to three digits is based on input good to at least three digits, for example. If the input has fewer significant figures, the answer will also have fewer significant figures. Care is also taken that the number of significant figures is reasonable for the situation posed. In some topics, particularly in optics, more accurate numbers are needed and more than three significant figures will be used. Finally, if a number is exact, such as the two in the formula for the circumference of a circle, c = 2πr , it does not affect the number of significant figures in a calculation.

Mark Twain left school when he was twelve. He had little school education but had to live. He made millions of dollars by writing whose real name was Samuel Langhorne Clemens, but he is better known all over the world as Mark Twain, his penname. Mark Twain was born in 1835 and he was not a healthy baby. In fact, he was not expected to live through the first winter. But with his mother's tender care, he managed to survive. As a boy, he caused much trouble for his parents. After his father's death in 1847, Mark Twain began to work for a printer, who only provided him with food and clothing. Then, he worked as a printer, a river-boat pilot and later joined the army. But shortly after that he became a miner. During this period, he started to write short stories. Afterwards he became a full-time writer. In 1870, Mark Twain got married. In the years that followed he wrote many books including Tom Sawyer in 1876, and Huckleberry Finn in 1884, which made him famous, and brought him a great fortune. Unfortunately, Mark Twain got into debts in bad investments and he had to write large numbers of stories to pay these debts. In 1904, his wife died and then three of their children passed away. At the age of 70, his hair was completely white. He bought many white suits and neckties. He wore nothing but white from head to foot until his death on April 21, 1910.(260 words) What brought Mark Twain fame and lots of money?

8.1-Magnitude Quake Hits Central Nepal Nepal is suffering from the disaster brought by a magnitude 8.1 earthquake that struck on Saturday. Nepal's Interior Ministry has said that the death toll from the quake has climbed to 1,931 . And more than 4,700 people are injured. Nepal's military predicts the death toll may climb to as high as 5,000. The Chinese embassy in Nepal has said that four Chinese were killed, with five severely injured. The initial magnitude-eight-point-one quake struck 80 kilometers east of Pokhara on Saturday afternoon. It was followed by a huge aftershock, measuring seven-point-zero. As for Sunday, two big aftershocks have been recorded in the morning, with the latest in the afternoon with a magnitude of 7.1. This is the most powerful earthquake to have hit Nepal in over 80 years. The tremor was felt by more than 4.6 million people across South and East Asia. Search and rescue efforts are underway for survivors buried under the rubble and flattened buildings, but efforts are influenced by rain and aftershocks. Nepal national television is reporting that 90 percent of historical structures in Kathmandu Valley were destroyed in the earthquake. Which statement is not true according to the passage?

MIT ( Massachusetts Institute of Technology) is a world-class university mainly in math, science and technology, but you may be surprised to learn that MIT sets arts courses. MIT believe in the passion of learning, the value of working and teaching methods. MIT's teaching power is quite strong. There are eight Nobel winners and many other national and international winners in the teacher group of MIT. MIT is proud of these top scholars and thinkers. The ratio of teachers and students in MIT is about 1 to 7.5. About 63 percent of the classes have fewer than 20 students each. Only 4 percent of the classes have more than 100 students each. Most MIT students can learn courses that they like. The students in MIT have many activities when they finish their lessons, for example: Student Life And Culture Student Organizations Music & The Arts @ MIT Athletics Most students in famous universities feel serious pressure both in life and study. In MIT the students have the same pressure which encourages them to have to study hard. But MIT usually gives one year for the new students to adjust to the transition (;). In their first term all the new students are graded by a test. In this test if he or she receives a C or the level better than C, his or her result will be kept forever.

The weights of one liter vegetable ghee packet of two brands ‘A’ and ‘B’ are 800 gm and 850 gm respectively. If they are mixed in the ratio of 3 : 2 by volumes to form a mixture of 3 liters, what is the weight (in kg) of the mixture?

[
"3.84",
"3.52",
"2.46",
"None of these"

C

Here's how I did it. My notes from reading the problem were:
1L A = 800 gm
1L B = 850 gm
We are mixing five parts (3 parts A plus 2 parts B, 5 parts total) to get 3L, so 5x = 3 ---> x = 3/5. Each part is 3/5 of a liter.
So if we have 3 parts A, we have 800*3*(3/5) = 1440
If we have 2 parts B, we have 850*2*(3/5) = 1020
1440 + 1020 = 2460
Solving for units gives us 2.46
So the answer is D

Lexi Peters, a 14-year-old girl in New York, loves hockey. She's not only good at playing on her after-school team, but also at playing hockey video games. But when Peters played the popular NHL (National Hockey League) games made by Electronic Arts, something really bothered her. The virtual character in the game could only be a boy -- not a girl. She didn't think that was reasonable. There must be many girls playing hockey in the US. So she wrote a letter to Electronic Arts. "Being represented by a man is unfair to women and girl hockey players," Peters wrote. "Women's hockey is a fast-growing sport. I am confident that I'm not the only woman interested in the opportunity to create herself in the game." Several weeks later, Peters received an unexpected e-mail from the senior producer for EA Sports' NHL games, David Littman. "Hi, Lexi," the e-mail began. "We agree with you!" Electronic Arts said it would create a female player in the game. "I was thinking you could be the model," Littman wrote. Peters almost couldn't believe it. Later, she sent photos of herself taken at all different angles . And so, when Electronic Arts released the newest version of their game, NHL 12, this fall, Peters was the face of the female player. She can now skate with the NHL's great players. "It's strange at first, but you get used to it," said Peters. "It's really funny and cool." For Peters, there is also an important lesson that she will take with her the rest of her life. "If you have something to say, and you think it's important, go for it!" she said. Peters' experience tells us that we should _ .
