They are lived a man in a village

After walking for days, the boys are captured by a group of soldiers and taken to Yele, a village occupied by the military. There, they are put to work chopping vegetables, carrying water, and washing dishes. It is a welcomed relief, but Ishmael suffers severe headaches daily. The village seems an oasis of normalcy in the war, but it is flooded with orphans. Ishmael writes that there is nothing to fear during the days in the village: children play soccer and marbles and parents tend their children. But Ishmael suffers migraines and nightmares and withdraws from village life.

Explanation:

C. It is human nature to mock or make light of problems we have been delivered from​.

Explanation:

Nathaniel Hawthorne's "Dr. Heidegger's Experiment" revolves around the doctor in his search for the fountain of youth. The story delves into themes of mortality, reformation, reality, mystery, etc.

Dr. Heidegger had invited four of his friends to try out his "fountain of youth" and see if it works. Once the water had been consumed by the four, they began to change, aging backward. What was once old and saggy skin, turned into youthful-looking individuals. And once they became youthful, they began to mock their "old-fashioned attire--the wide-skirted coats and flapped waistcoats of the young men, and the ancient cap and gown of the blooming girl." The statement that "[the] singular effect of their gayety was an impulse to mock the infirmity and decrepitude of which they had so lately been the victims" seems to suggest that their gaiety over their transformation only resulted in them mocking their old selves' fashion choices.

This shows that human nature is prone to make fun of or criticize the problems that one has just gone through.

Thus, the correct answer is option C.
