What is the best summary of this paragraph? Another thing that changed very little in the years between the wars was the means of obtaining military intelligence. Although the use of photography and the telegraph brought some technological advances, the craft of spying on the enemy's army still relied on fieldwork. For the most part, intelligence was gathered in simple ways. Prisoners of war and deserters were interrogated. The Union army was always interested in hearing what runaway slaves had to report. And, of course, both armies relied on cavalry scouts, signal intercepts, visual observation, and captured correspondence.

A. During the Civil War, intelligence was gathered in the same ways it had been gathered in previous wars.

B. Photography and the telegraph were some of the technological advances that were used in Civil War espionage.

C. Most espionage during the Civil War was fieldwork that included observation, scouting, and interrogation of prisoners.

D. Enslaved persons that ran away, as well as prisoners from the Union Army, were good sources of information during the Civil War.

C

Explanation:

For the most part of the war, armies preserved old military tactics (fieldwork) of espionage rather than fully adapting to new techniques.

Here's why the other answers are incorrect:

A) "Photography and the telegraph brought some technological advances" in comparison to the previous wars, so A is incorrect. Intelligence was, for the most part, gathered in the same ways it had been previously, but these new technologies were still utilized.

B) Photograph and the telegraph are mentioned, but they are not the main point of the paragraph. Basically, "although the use of photography and the telegraph brought some technological advances," this fact is only being mentioned in the paragraph to emphasize the minimal progress of "the means of obtaining military intelligence," as intelligence was often still "gathered in simple ways" only. Armies "still relied on fieldwork." So B is incorrect.

D) Option D only refers to one source of information in the paragraph, "runaway slaves;" it does not fully or efficiently summarize the paragraph.
