We know that the kitten was "underfed" and "its skin [looked] tight against its bones," so we need to pick out an adjective that means something like "emaciated." "Plump" and "healthy" are antonyms of the word we're looking for, so neither can be the correct answer. "Gaunt," an adjective that means "lean and haggard, especially because of suffering, hunger, or age," is the correct answer because it best fits the sentence's context.

The contrast being asserted in this sentence is between “sequential” actions and ones that would be done in a non-sequential manner. A process that is done “sequentially” is one that has a number of steps done one after another. Therefore, the best contrast to this would be a process having steps done at the same time, or “simultaneously.”   The “simul-” portion of the word comes from the Latin meaning “at the same time” and is distantly related to other “sameness” words like “similar” and “similarity.”

Since the young scholars are described as being “overly confident,” the best option will reflect such confidence. They will thus be described as being very certain or as having unwavering certainty. When something is “apodictic,” it is considered to have been completely demonstrated, leaving no room to doubt it. This would well describe the great certainty of the young scholars.           

The contrast in this sentence is between someone who is said to be generally emotional and someone who is not. Just because Karen is emotional and agitated, one need not believe that she was nasty, sad, depressed, or anything else. The best contrasting term is “stoic,” meaning “undergoing difficulties without showing emotion.” It is often used in the broader sense of implying that a person shows no emotion when it would seem normal to do so. The term is taken from the ancient Greek (and later Roman) philosophical school (the Stoic school of thought) that is often given the simplistic characterization of promoting this kind of outlook on life.

The best guide for answering this sentence is the expression “easily overlooked,” though the remark about “immediate evidence” is also helpful. When something is easily overlook and not evident with blinding immediacy, it can be said to be “subtle,” meaning that it is either indirect or even (more properly) fine / delicate. Something very “fine” or “subtle” is something small—i.e. not large, blatant, and obvious.

Since the expression “raging irately” is used in the participial clause, the best option will be the word that is as strong as this expression. The word “tempestuous” indicates such a strong temperament, better than the much weaker “disagreeable” and “unfriendly.” The word “tempestuous” literally means “like a storm,” as can be seen in its obvious relation to the word “tempest.”

Although one might say that the state was going to watch the questionable group, the contrast in this sentence is really with “persecution.” In opposition to that, it would be best to choose “tolerant,” for when one tolerates a group, he or she allows it to exist, even if it seems questionable or even undesirable. The sentence does not speak directly about surveillance and therefore does not merit the choosing of “vigilant,” “aware,” or “watchful.”

Since the sentence directly mentions star charting, the best answer will be that which describes the data as being related to heavenly bodies or stars. Therefore, the two “astro-” options should stand out immediately. Here, you must be careful not to confuse the two words. Astrology is concerned not with the science of measuring (etc) stars but with the so-claimed “meaning” of stars in the sense of horoscopes and things of that sort. It is astronomy that studies the scientific laws of the stars. This is indicated by the “-nomy” at the end of the word, which is derived from Greek word for “law.” It is found in the word “autonomy,” literally meaning “having a self-given law.”

The key words to note are “musical” and “flowing.” The best description of the teacher’s voice will reflect these two parallel descriptions. Probably the most tempting trap answer is “fluent,” which means “flowing.” However, “lilting” better matches the two descriptions mentioned. A lilting sound is one that rises and falls in a pleasant manner. When applied to a voice, it means that it has such a gentle rising and falling. Although it does not directly mean “musical and flowing,” it does, by extension, imply a certain musicality and gentle flow to the voice. In any case, it is much better than “fluent,” which generally is used to describe one’s ability to speak well (often in another language) and only secondarily is used for the more general sense of “to flow;” thus, lilting fits more closely.

The key word here is “opposition.” Although the group was suppressed, we do not know anything about its legality. Therefore, the best option is “dissident,” which means “disagreeing” (with someone else). The word literally means “to sit apart from.” The “sitting” portion is reflected in “-sident” and “dis-” portion means “apart from” or “opposed to.”   Do not be fooled by “dissonant,” which means “a clashing sound.”
