Since we know that the neighbors had to go to court to settle their differences, we can infer that we're looking for a noun that means something like disagreement. Of the listed answer choices, only three are nouns—"adage," "mettle," and "dispute." Since "adage" means proverb or saying, it does not mean disagreement and is not the correct answer. Similarly, "mettle" means courage or fortitude and does not mean disagreement either. "Dispute," however, means a disagreement, so it is the correct answer.

We know from the context of the sentence that Emily was socially sensitive—while she could have pointed out the toilet paper in a more overt way, she did it in a way that did not embarrass her friend. We have no reason to suspect that Emily was absentminded, and "comfort" and "hurry" have nothing to do with the situation either. "Jubilance" is a noun meaning triumph, so "jubilance" does not fit the context of the sentence either. "Tact," however, is a noun meaning sensitivity in dealing with potentially embarassing or awkward issues, so "tact" is the answer choice that best fits the sentence and the correct answer.

The young man in this sentence is acting like everything's fine, even when it's not. Two of the answer choices could fit with this sense of acting: "charade" and "façade."

"Façade" is related to the word "face," and means to put on a false face (either as a fake front of a building or as a deceptive facial expression).
