Question

which of the following is an example of a claim that a historian might make about the american civil war?
a. former slaves fighting in the union army were essential to several northern victories.
b. president lincoln wrote in a letter, \if i could save the union without freeing any slave i would do it.\
c. the american civil war had many causes, and this paper will explain them all.
d. the emancipation proclamation freed slaves only in states that had seceded from the union.

Explanation:

A historian's claim involves interpreting or analyzing historical events. Option A presents an interpretation of the role of former slaves in Union victories. Option B is a direct quote (a primary source), Option C is a paper's introduction (not a claim), and Option D is a factual statement about the Emancipation Proclamation. So A is a historian's analytical claim.

Answer:

A. Former slaves fighting in the Union army were essential to several Northern victories.
