original passage: In September 1937 the Spitfire prototype, "K5054," was fitted with ejector type exhausts. Later marks of the Spitfire used a variation of this exhaust system fitted with forward-facing intake ducts to distribute hot air out to the wing-mounted guns to prevent freezing and stoppages at high altitudes, replacing an earlier system that used heated air from the engine coolant radiator. The latter system had become ineffective due to improvements to the Merlin itself which allowed higher operating altitudes where air temperatures are lower. Ejector exhausts were also fitted to other Merlin-powered aircraft.

sentence2: Was the Nazi regime offended by the presence of Jewish athletes from other countries?
sentence1: Hitler saw the 1936 Games as an opportunity to promote his government and ideals of racial supremacy and antisemitism, and the official Nazi Party paper, the "Völkischer Beobachter", wrote in the strongest terms that Jews should not be allowed to participate in the Games. German Jewish athletes were barred or prevented from taking part in the Games by a variety of methods, although some women swimmers from the Jewish sports club Hakoah Vienna did participate. Jewish athletes from other countries were said to have been side-lined to prevent offending the Nazi regime.
