The key word in this sentence is "plane." That simple context should lead you instantly to "hangar," which has the specific meaning of a building that houses planes.

The two key words are “complacency” and “laziness.” This implies a particular slowness and lack of effort. When one “saunters,” he or she walks in a slow and somewhat lazy manner—as on a slow walk down the trail.

In this sentence, it is really a matter of knowing the vocabulary, though you can likely eliminate several options as being a bit too limited. The most tempting wrong answers are both “contribution” and perhaps (if one thinks too much) “waiver.” Strictly speaking, the latter would imply more than what is said in the sentence. Against the option of “contribution,” the word “stipend” is better, as it means “a fixed salary, payment, or allowance.” “Contribution” is more vague than “stipend,” and therefore is less acceptable.

If something is “anachronistic,” it does not really belong in its given time period. Sometimes, the adjective can merely mean that something is old-fashioned, but it often is used to indicate the situation when someone describes something in one time period according to the customs or historical contingencies of another period. The prefix “ana-” comes from the Greek preposition meaning “backward” (among other things). The familiar “-chronistic” comes from the Greek word for time and has familiar English derivatives (such as “chronological”).

While “dilettante” may be related to the sentence and appear a potential choice, it indicates a person who cultivates an area of interest, such as food, but without any real commitment, only dabbling in it. The sentence indicates that the person in question has a knowledge more extensive than the rest of the group, so “epicure” is the more suitable answer choice.

A "cacophony" is a clamor or harsh noise, which is implied by "disruptive" and "resonating."

The adjective “veritable” is used to intensify noun that it describes. It could be translated “quite truly.” (It is related to words like “verity”, “veridical”, and “verify.” All of these come from the Latin "verus," meaning true.) Since the room was deadly in its heat, it is best called an "inferno," at least metaphorically speaking. An inferno is generally a large fire. The word is related to the late Latin word for “Hell.” It communicates the idea of great amounts of heat and does so without the “health benefits” that are somewhat connoted by “sauna.”

Although it is possible that the president was "enraged" by the presentation, we have no indication about his overall personality or disposition at this time. Therefore, it is best to use the hints in the expressions "not . . . merely boring" and "waste of time." He thought that the presentation was completely worthless. Thus, "inane" works well, for it means stupid or pointless.

The point of this sentence is that while Felicity did not have an overabundance of funds from her pay, she did earn enough for her lifestyle. The word "accepting" is perhaps tempting because it is close to "acceptable." To be "accepting," however, means to be receptive of something. This is not exactly the same as "acceptable", even though the two words certainly are related. When something suffices, it is enough. Thus, a sufficient amount of funds are enough for someone—as in this case for Felicity.

The point of this sentence is that Thomas was well known and famous in his day. Thus, his position was one of prominence among the scholars of his time.  Prominence is the state of being famous. A "prominent" person is someone who "sticks out" in the crowd, who is noticeable (usually because of excellence). A mountain peak can be prominent if it towers high above the others surrounding it.
