The best first clue for this sentence is "his indomitable will." The root "domi-" can come from "dominus" in Latin, meaning lord. (Do not confuse this with "domus", meaning house and found in the English "domicile.") When something is "indomitable," it has no lord; it cannot be overcome. The simple word "tasks" works well enough for the first blank. We really only know that Étienne has a general undertaking—tasks. Something that is "insuperable" is not able to be overcome. Trusting in his undefeatable will, Étienne thinks he can overcome such seemingly impossible tasks. The implication is that he trusts that he can outlast such hardships. Hence, he can "persevere" through them.

We know based on the context of the sentence that the first blank is describing some undersirable or negative characteristic regarding the rise in unemployment. Given this context, "disquieting," meaning upsetting or concerning, and "aberrant," meaning departing from a norm, could both make sense. "Antidiluvian," meaning outdated, "inchoate," meaning undeveloped or in an early stage of development, and "caustic," meaning sarcastic or biting, don't make sense here. This narrows our choices to either "disquieting . . . discomfiture . . . fatuous" or "aberrant . . . antipathy . . . dogmatic."

We can see from the context that the second blank describes some negative reaction resulting from the increase in unemployment. "Discomfiture," meaning an unsettling or disconcerting state, and "antipathy" meaning aversion or antagonism, could both potentially work. Moving to the final sentence, we know that based on early information detailing the rise in unemployment, the mayor's speech about "unlimited opportunities" seems untimely and silly. "Dogmatic," meaning opinionated or dictatorial, doesn't really fit perfectly; however, "fatuous," meaning silly, naive, or pointless, does make sense given the context. Thus, we know the correct final answer is "diquieting . . . discomfiture . . . fatuous."

The context for the first two blanks might not be readily apparent, but if we jump to the final sentence, we are able to provide some context for the first sentence. We know based on the final sentence that some diets are "taxing" and emotionally draining, and that a balanced approach to diets is advisable. Using this information, we can go back to the first blank and infer that the first blank implies some positive action or attitude regarding diets, which the second blank qualifies in some way. "Extol," meaning praise, "condone," meaning accept, and "laud," meaning praise emphatically, all could make sense. "Descry," meaning see, and "occlude," meaning obstruct, don't really seem to fit in the meaning of the sentence. 

This allows us to narrow our options to "extol . . . asceticism . . . onerous," "condone . . . veracity . . . tractable," and "laud . . . probity . . . panegyric." Given that we know that it is easy to act in some positive way toward diets, but that the end of the sentence advises us to not be too extreme in some action toward those diets, "asceticism," meaning unindulgent self-discipline, certainly makes sense, and "probity," meaning strong principles, also potentially works. "Veracity," meaning truth, does not really fit in the sentence. Given the context of the final sentence, advocating for a balance between mental and physical health, "onerous," meaning burdensome, makes perfect sense. "Panegyric," meaning a speech that praises something or someone, does not fit at all. As such, we know the right answer is "extol . . . asceticism . . . onerous."

Based on the context of these two sentences, we can tell that the individual in question has commited some "base and undignified crime." Furthermore, based on the use of "hard to imagine," we know that, even though he wasn't well-liked, his employees still felt that his actions were surprising. As such, we can reasonably infer that the first blank will involve conveying a sense of surprise or shock, that the second blank will in some way describe the severity of the crime committed, and that the third blank will describe a characteristic that contrasts with "base and undignified." 

Given this, "flabbergasted," meaning astonished, and "bewildered," meaning perplexed, both could make sense for the first blank. "Nonplussed," meaning unphased, would clearly not work here. "Chagrined," meaing embarassingly vexed, isn't completely nonsensical, but doesn't quite fit given the context. "Buttressed," meaning supported, also does not work. This narrows our options down to "flabbergasted . . . odious ... highfalutin," or "bewildered . . . insipid . . . prodigious." 

Moving to the next blank, we can see that "odious" is a definite possibility, as it means revolting. "Insipid," meaning unimaginative, does not seem to work quite as well. This is confirmed when we examine the final blank, in which "prodigious," meaning impressively large, gives a nonsensical meaning to the sentence. By contrast, "hghfalutin," meaning pompous, fits the context perfectly, and so by process of elimination, we are left with the correct answer: "flabbergasted . . . odious . . . highfalutin."

Based on the fact that the sentence describes certain other painters as having less talent than Harish, we can infer that the first blank, followed by the word "talent," will have some positive meaning. Since the second blank, following "unmatched," seems to reinforce the positively characterized talent in the first blank, we can infer that the second blank is probably some noun or adjective that would support this claim. Since the sentence makes clear that Harish is not very business-minded, and that he is often outsold by less-talented painters, we can infer that the final blank, following the phrase "superior business . . .," is probably some noun that describes some postive skill or quality relating to business. 

Given the aforementioned context for the first blank, "singular," meaning unique, and "auspicious," meaning promising, both could potentially work. "Quiescent," meaning dormant, and "opaque," meaning non-transparent, don't seem to fit well. Similarly, "hapless," meaning unlucky, also doesn't make much sense. This leaves us with two answer possibilities: "singular . . . virtuosity . . . acumen," and "auspicious . . . diligence . . . encomium."

"Virtuosity," meaning mastery, and "diligence," meaning persistence, both potentially work for the second blank, so we are still not able to eliminate either option. Moving to the third blank, "acumen," meaning cleverness in a specific field, clearly makes sense for the third blank; however, "encomium," meaning a written text that praises someone or something, makes no sense at all. This gives us our answer: "singular . . . vituosity . . . acumen." 

Based on the context, we can tell that the professor has some quality (first blank) that makes her able to transform some routines that are some description similar to "commonplace" (second blank) into a source of rich discussion. We also know that the third blank is some adjective qualifying "morning hygiene rituals," and that it probably contrasts with adjectives that would be used to describe something that would typically "reveal deep insights into human nature."

For the first blank, "enrapturing," meaning captivating, and "lucid," meaning clear, could both make sense. "Forlorn," meaning pitiful or hopeless, "muddled," meaning confused, and "opaque," meaning non-transparent, don't work well at all. This narrows our options to "enrapturing . . . prosaic . . . quotidian" and "lucid . . . quentessential . . . fraught." 

"Prosaic," meaning everyday, could clearly work as a qualifier of "routines." "Quintessential," meaning a good model or example of something, doesn't fit perfectly as a description of routine. Moving to the third blank, "quotidian," meaning everyday, definitely makes sense as a description of "morning hygiene rituals," whereas "ersatz," meaning substitute, does not. This leaves us with the correct answer, "enrapturing . . . prosaic . . . quotidian."

Based on the second sentence, we know that the man is not refined, as the guests are surprised that a refined woman would be with him. It then becomes clear that his behavior at dinner was probably some negative quality, and that he was lacking some thing or quality that he should have.

Since we know the first blank is some negative quality, "boorish" meaning bad-mannered, and "crotchety," meaning grumpy, both could work. "Endearing," meanign generating affection toward someone or something, "assiduous," meaning diligent, and "laconic," meaning meaning saying very little, do not make sense. This leaves us with "boorish . . . decorum . . . uncouth" or "crotchety . . . mores . . . urbane." Moving to the second blank, it would make perfect sense that the man would be lacking "decorum," meaning propriety. It could also make sense that he might be lacking in "mores," meaning social customs. 

For the third blank, "uncouth," meaning crass, works perfectly as a counterpoint to "refined." "Urbane," meaning sophisticated, would not. As such, we are left with "boorish . . . decorum . . . uncouth."

Based on the fact that the billionaire is described as "a darling of the charity world," we can ascertain that the general tone of the sentence will probably be positive. 

For the first blank, "lavishness," meaning extravagance, and "grandeur," meaning splendor, both make sense as a description of the billionaire's house. "Veneer," meaning a thin exterior coating or false front, does not make sense at all. "Haughtiness," meaning arrogance, and "magnanimity," meaning generosity, could have some relevance given the sentence's subject matter, but do not make sense as a description of a house. This leaves us with a choice between "lavishness . . . largesse . . . epitomize" and "grandeur . . . stinginess . . . revitalize."

Characterizing the billionaire as having "largesse," meaning generosity in giving money, makes sense given the statement that he is a "darling of the charity world." However, "stinginess," meaning miserliness, clearly contrasts with this claim, and as such, does not work. At this point, we have narrowed down the correct answer by process of elimination; however, just to double check, we can look to the third blank. Here we see that it would make sense that he would "epitomize generosity of spirit," as "epitomize" means exemplify. We now have the correct answer: "lavishness . . . largesse . . . epitomize."

"Edifice" can be defined as a structure, "maintained" as sustained, and "restored" as repaired. All of the other answers do not fit the context of the sentence when used together.
