How did the embargo act spark american industry?

it made european trade more desirable.
it increased illegal goods.
it made americans self-reliant.
it caused the government to invest in industry.

Embargo Act of 1807 developed US industry as it focused the trade in European countries. In 1803, Britain and France war, US tried to control and continue to trade in both countries. It wasn’t successful because both countries prohibit the trade for countries not taking sides.

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
