What is it called when writers are influenced by their time and its social, political, cultural, and economic characteristics?

d. the two authors are in awe of nature; their experiences, reveal that time in nature can change people.

explanation:

in "people in peace, not profit and war" chrisholm uses inductive reasoning for her argument against defense spending by stating that the new administration, like most americans, wanted to invest in social objectives, so they must not want to prioritize defense spending. mr. nixon said "we can delay no longer in launching new approaches to the problem that beset them", but chrisholm points out that the programs were delayed anyways.

b. cronkite, a trusted television personality, declared that the war was unwinnable and told the american people that the government had better find a way out

even though it went against everything the news anchors typically stood for, cronkite voiced an opinion and took a stance, telling the us that there was no way they were going to win, the war was going to end in a stalemate. 

i think the best answer would be d allowing 30 seconds between response would give time for what was already said to sink down in your mind.
