Since Sputnik was an artificial satellite (the world's first), it had no direct effect on athletics. It definitely did not foster cooperation between the US and USSR, but actually led to a competitive space race to prove each country's superiority over the other. There was no need to send nuclear missiles into space, so C. is just wrong. The correct answer is D. it prompted a space race between the U.S. and U.S.S.R.
