Question

what primary concern did albert einstein raise to president franklin roosevelt about the development of the atomic bomb?
○ it had potential not to merely win the war but to destroy human civilization.
○ its uncertain power could be so great as to knock the earth off its orbit.
○ germany was on track to develop nuclear technology before allied forces.
○ it could be too expensive and time - consuming to be used before the end of the war.

Explanation:

Einstein's concern was about the destructive power of the atomic bomb. The first option highlights the potential for civilization - destroying power. The second option about knocking Earth off orbit is a myth. The third option (Germany's nuclear tech lead) was a reason for developing the bomb, not a concern about its use. The fourth option (cost and time) was not Einstein's main worry.

Answer:

It had potential not to merely win the war but to destroy human civilization.
