Answer:
Correct answers are Both men were presidents during World War II and Both men met with Allied leaders to plan for the end of the war.
Explanation:
These options are right, as Roosevelt was president from 1933 until his death in 1945. Truman took the office in 1945, and was at the head of the United States, when the war ended. Both presidents participated in many Conferences with Allied leaders to discuss the end the war, but never together.
Truman was present at Potsdam and Roosevelt at Yalta, that is why those two options are wrong. Truman is the one that issued declaration Japan's unconditional surrender.
The provisional government continued Russia's involvement in World War I.
