What did the lend-lease act do? a. it permitted all warring nations to borrow military equipment from the united states as long as they promise to return it after the war. b. it permitted great britain to borrow military equipment from the united states as long as they promised to return it after the war. c. it permitted great britain and germany to rent military equipment from the united states throughout world war ii. d. it permitted germany to rent military equipment from the united state at very reasonable rates.

explanation:

there are two statements that are incorrect.

1. the marshall plan was a lend lease program. it was an economic plan that europe redevelop itself after wwii.

2. einstein didn't really do anything to further the allied cause in building the bomb. he merely sent a letter to fdr telling him (in 1939) that if the united states entered the war, perhaps it would be wise to build the bomb before germany did. i would say this answer is incorrect, but when america entered the war 2 years later, fdr thought it might be a good idea to take einstein's advice.

the 4th choice is definitely so wrong that is likely the single answer of this question
