The red sky is a warning or a sign, so we need a word that fits the definition of something that could be considered a warning. "Harbinger" is the only answer choice that fits.

A "tome" is a large book, something a professor would use to begin a lecture.

Falling down the stairs and awaking the neighborhood implies that there was a lot of loud noise, and so "clamor" is the only answer choice that fits.

A "maverick" is an independent, non-conformist person. A composer who does not follow past or present trends is surely a non-conformist, a maverick.

A "neophyte" is someone who is inexperienced in a certain field. Logically, a skydiver who waited for the more experienced to jump would be regarded as a relative novice, a neophyte.

"Pathos" means an emotion of sympathy. Certainly, a young priest would feel great sympathy at the sight of suffering in his own village.

"Legerdemain" is slight-of-hand or a deception. A con artist would rely upon deception to steal from a widow.

A "polemic" is an aggressive argument against a specific opinion. The husband's argument against wasteful spending, though possibly reasonable, is undermined by his hypocrisy.

Our clues in this sentence are about the coach who “welcomed” the new team member and “his interest” in developing a “cohesive team spirit” so it sounds like the coach was looking forward to adding this person to the group. We need a word that is positive.

Let’s check for clues in the answers: The word “aloof” sounds like roof, aloft, alone or along which do not seem exactly positive or welcoming. The word “respite” might remind you of words like respond, respiration, responsible which are positive words but not very related to friendly team spirit building.

“Hospitality” usually means to show people that you are welcoming them with sincere interest and words like hospice, host, and hospital relate to taking care of others so this may be our best answer but let’s keep checking. 

The word “aspersion” might sound familiar because it may remind us of aspire which means to strive toward becoming better or desiring fame. But “aspersion” also sounds and looks like asperity which means roughness in manner and this does not fit so let’s not chose aspersion.  

So “effacement” is our last answer and it may remind us of effect, effort, effective or efficiency. None of these seem related to welcoming either so let’s chose “hospitality” as our answer which does mean to welcome warmly.

While all the answer choices indicate some measure of ill feeling, only “animosity” indicates the correct seriousness.  “Antipathy” and “coolness” indicate a carelessness, while “impatience” does not have an appropriate level of seriousness. "Harmony" means the exact opposite of ill feeling.
