"Unadorned" and "unostentatious" both mean not showy, so those would be characteristics of a modest house, and we want something to describe the opposite of this. "Squalid" and "begrimed" both describe very filthy and impoverished conditions. These are not conditions that one would take on as one's means grew. "Baroque," meaning lavish or extravagant, is the best choice.

"Frugal" and "sparing" both mean lacking, but the point of this sentence is that English has a lot of different types of words, so these choices do not make sense. "Mediocre" and "unremarkable" mean average or ordinary, so also do not make sense since the sentence is about the vast capabilities of English expression. "Comprehensive," meaning extensive, is the best choice.

The sentence directly ties the subject's lifestyle, described by the missing word, to the fact that he "aged quickly." This means the correct answer will indicate that the subject's lifestyle was destructive or problematic. "Intemperate," meaning excessive or immoderate, is the best choice.

The sentence gives two clues to the missing word, both the "break up" and the teenager's "never smiling" after it. This means the correct answer will mean sad or depressive, the definition of "lugubrious."

The subject's reaction to the news meant he "refused to talk for months afterward." This means the correct answer needs to carry an appropriate sense of bewilderment. "Nonplussed," meaning confused or completely shocked, is the best choice among the answers.

The subject's magic tricks "ruined any chance he had at a second date." This means his date was not impressed with his magic, and it was highly unsuccessful. "Artless," meaning lacking in skill or clumsy, is the correct answer.

"The ignorant utterances" are a "surprise" when coming from the lawyer, who is described by the missing word. The correct answer will therefore mean the opposite of "ignorant." "Erudite," meaning well learned or scholarly, is the best choice among the answers.

The structure of the sentence explicitly contrasts the missing word with the girl's "usually cheerful" nature. The correct answer will be an antonym of "cheerful" in some manner. "Plaintive," meaning sad or mournful, is the best choice.

If Georgiana Spencer's ideas were to be "rebuffed" or "spurned," that would indicate that they had been rejected by the greater populace. On the other hand, if her ideas were "disregarded," that would mean that they had been ignored. And had they been "disdained," her ideas would have been hated by most people. Thus "prevalent," meaning widespread, is the best choice.

Self-interested Scrooge would be doing things that were good for his financial interests, but "detrimental to," "disadvantageous to," "inimical to," and "unhelpful to" all mean bad for. "Beneficial" means advantageous and is definitely the best choice.
