Question

Which of the following men was a physicist who left Germany and influenced Roosevelt enough to build an atomic bomb?
Albert Einstein
Chester Nimitz
James P. Byrnes
Harold Ickes

Answer 1

Let's step through this one:

It's not Nimitz, he was a Navy admiral. Not Byrnes because he was a politician. And not Ickes, either, because he was cabinet member of Roosevelt's government.

So the right answer is definitely Albert Einstein. Einstein left Germany because of the rise of the Third Reich and warned Roosevelt of the danger and the possibility of Nazi Germany building an atomic bomb.
