As you read the excerpt below, think about how you would summarize it. On the military side, realization that a bomb would probably be ready for testing in the summer of 1945 led to concrete planning for the use of the new weapon, on the assumption that the bomb when completed would actually work. By the end of 1944, a list of possible targets in Japan had been selected, and a B-29 squadron was trained for the specific job of delivering the bomb. It was also necessary to inform certain commanders in the Pacific about the project, and on 30 December 1944, Maj. Gen. Leslie R. Groves, head of the Manhattan District, recommended that this be done.

Which sentence best summarizes the paragraph?

a. The military worked quickly to plan for the bomb's use once they knew the bomb was ready for testing.
b. Maj. Gen. Groves had the important job of updating commanders about what was happening with the bomb.
c. Most Americans did not realize the important plans that were going on behind the scenes during World War II.
