original passage: The flag of Belgium (,) is a tricolour consisting of three equal vertical bands displaying the national colours of Belgium: black, yellow, and red. The colours were taken from the coat of arms of the Duchy of Brabant, and the vertical design may be based on the flag of France. When flown, the black band is nearest the pole (at the hoist side). It has the unusual proportions of 13:15.
original sentence: It has the unusual proportions of 13:15.
sentence2: If someone printed the flags of France and Belgium on a greyscale inkjet printer, that was low on ink, and was using old, discolored paper (yet they still managed to print the flags at their designated proportions) would there be a way for a viewer to say without a doubt which flag belonged to which country no matter how bad the print job was?
