The contrast here is between the rarity of Odo showing any dislike and a recent case that differed from this normal practice. When someone shows “animus,” he or she is said to show ill will or hostility. The word comes from the Latin for “soul” or “mind” as found in words like “animal” and “animated.”

Since the two personalities are opposed, it is necessary to think of an opposite for Laura’s troublesome drama. While this might be annoying to her husband, the key is to choose the word most opposed to this dramatic persona. That would be “aloof,” not any of the others.

Someone who is “saccharine” is excessively sentimental or sweet. It comes from the Latin word for sugar, and in modern times the manufactured substance called “saccharin” has been used as a substitute for sugar.

By looking at the contrast established in this sentence, we can say that Francis must have been something of a womanizer or rather promiscuous during his college days. Such a person is called a “philanderer,” a term almost always applied to men.

This is in because of its literal meaning, “man of (many) love(s)” from “phil+anderer.” The “phil-” portion is found in words like “philosophy,” which means “love of wisdom,” and “Philadelphia,” “(the city of) brotherly love.” The second half comes from the Greek word for man and is found in English words like “android,” and “polyandry” (meaning “having many husbands”).

The structure of the sentence, and the employees' surprise, indicates the new manager was not easygoing. The correct answer choice will be the one that is an antonym of "easygoing." "Abrasive," meaning harsh and coarse, is the only such answer choice.

The implication here is that the work of astrophysicists has been more capable and effective in bringing forth practical advances (in comparison with theoretical mathematicians). When one can bring forth results in an effective manner, such a person (or institution) is unsurprisingly called “efficacious.” This word has many relatives, as might be surmised, such as “efficient,” “effect,” and “efficacy.”

The contrast here is with the word “bodies” in the first phrase, so do not go any further than that meaning if possible. While “invisible” and “hidden” are tempting options, “incorporeal” most directly answers to the need in this regard. It means not having a body. In this word, the prefix “in-” is a negative prefix meaning “not,” and the “-corporeal” portion is derived from the Latin for body. It is related to other words such as “corpulent,” “corpse,” and “incorporation.”

The contrast here is between excitement and what must be a rather detached and disinterested response from Timothy. When liquid is barely warm, it is said to be “tepid.” By extension, this becomes applied to persons to say that they are “lukewarm” or that they show little interest or passion for a given thing or things.

The contrast in this sentence is between Tilghman’s “svelt” siblings and himself. If someone is “svelt,” he or she is slender; therefore, if he is not svelt, Tilghman must be fat or “corpulent,” which means the same.

The word is derived from an almost identical Latin root that means the same and is more distantly derived from the Latin for “body” found in words like “corpse,” “incorporation,” and “corporeal.”

The key word here is “imprecision.” The “im-” prefix is privative, meaning not. Something "imprecise" is hazy or vague. While it might be tempting to think that the young man liked showing that people were stupid (i.e. "fatuous") or even "rustic" or "imprudent," the best option is the one most closely matching “imprecision,” and that option is “vague.”
