The story likely takes place during the civil war in the United States. The Rostina Sharpshooters were a regiment of soldiers (all of whom were marksmen meaning they could hit what they aimed at). The men in question are being shot at by these sharpshooters who must be too far away even for them. But the men are quite nervous about what they are doing. 
If you consider this an example of very black humor, then E is your answer. Certainly the men are uneasy. They feel comfortable about nothing that is going on. They are hesitant to search the body. They are very tentative about how to deal with the service. They can't make up their minds if they should continue with the body or wait until the next day. They can't remember the service. Everything about this scene is delay, discussion and a hesitant move forward. They even have trouble with where to put the first few shovelfuls of dirt. You have to pick uneasy. 
You have to pick E, but if it is humorous, there certainly is no laughter.

The correct answer is D. Weed tree that wreaks havoc on the environment is referred to favorably as the "tree-of-heaven."
Explanation:
Irony occurs when the outcome in a situation is not the one expected or words have an opposite meaning to the literal meaning. In the excerpt, there is irony because the three known as the "tree-of-heaven" in China is an invasive and harmful species. This can be seen in "implacable invaders capable of rooting in tiny chinks in subway tunnels" and in "heaving up sidewalks and wreaking havoc in sewers" that shows the power the tree has to invade spaces and destroy structures despite the name suggests the tree is positive. This means there is an incongruence between the expectations about the tree and the reality. Thus, the statement that explains irony is statement D.

Answer:
c: Champollion was amazed after seeing Karnak
Explanation:
Jean-François Champollion was a French linguist most famous for his work on Ancient Egypt and for deciphering Egyptian hieroglyphics.
In this excerpt we can clearly see signs of deep admiration and fascination Champollion had towards Egyptian culture, society and especially architecture. 
That can best be seen from his sentence: "No nation on earth, ancient or modern, has ever conceived architecture on so noble and vast a scale".
This diary entry suggests that he was extremly amazed at the sight of Karnak.
