state of nature / social contract

Explanation:

Theorists like Thomas Hobbes, John Locke, and Jean-Jacques Rousseau, developed different theories about the state of nature and the social contract, although their underlying ideas shared some similarities.

The state of nature refers to a real or hypothetical condition of humanity before any political association, and the social contract would be also either a real or hypothetical understanding about the rights and duties of the rulers and the ruled people.

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

bismarck believed in using force

is the correct answer!
