Why did european monarchs declare war on france during the french revolution? to protect the endangered aristocracy to end the persecution of the former monarch to stop the new ideals of freedom and equality to gain control and influence over another area

to end the persecution of the former monarch. - second choice

to protect the endangered aristocracy

Explanation:

French revolution created an atmosphere of anxiety among the other European nations. they were left with two options either to took advantage of the disturbance in France or to nobility of France. They soon realized that the revolution can affect their states and they rush to protect the hierarchy, prevalent in Europe.

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

true is the answer to this
