If the doctrines of a thinker or group of thinkers have internal conflict, they do not “hang together” well in a single cohesive manner. The term “coherence” comes from Latin roots meaning “to stick together.” The “co-” portion gives us the “together (or with)” in this meaning, while “-herence” is related to words like “adhere,” “adhesive,” and “cohesion.” If something is “incoherent,” it does not make sense as a whole—the pieces do not “stick together” well.

Since Benjamin’s mother seems “to know all,” it would be best to say that she appeared to be “omniscient.” This word literally means “all-knowing.” The prefix “omni-,” meaning “all,” is found in English words like “omnivorous” and “omnipotent.” The “-science” portion of the word means not merely “science” but instead more broadly means “knowledge.”

Most properly speaking, a woman with many husbands is practicing “polyandry.” This word literally means “many husbands” or “many men.” The “poly-” portion means “many,” as can be seen in other English words like “polymath” or “polyglot.” The “-andry” portion is derived from the Greek for “man” and is found in words like “androgen” (male hormones) and “androgynous” (a person looking neither wholly male nor female). This latter term also shows why you should not confuse “polygyny” with “polygamy.” The latter means “having more than one husband or wife,” while the latter means strictly “having more than one wife.” The “-gyny” portion of that word is related to the same base found in “gynecologist,” a doctor specializing in female diseases and reproductive issues.

The sentence implies that the manuscripts led to a revival of classical music in the culture. Literally, a “re-vival” is a “re-living” or a “re-enlivening.” The term “renaissance” is closely related to these expressions, literally meaning a “rebirth.” The “-naissance” comes from Latin roots for “to be born” found in words like “natal,” “nativity,” and “nascent.”

Since Lawrence could empathize with oppressed groups, he could be said to feel united with them. Such connection is known as “solidarity,” a word distantly related to the roots for “solid.” In its original Latin, this was used particularly in the sense of having the same material throughout a given solid mass. Thus, “solidarity” has the sense of unity across multiple people or groups of people.

Since the substance was able to deflect bullets, it was not able to be penetrated by them; therefore, the best option for this sentence would be “impenetrable.” The only other close option would be “insuperable,” meaning unable to be overcome; however, the sense implied by the sentence is clearly that the barrier does not leave bullets through its surface.

The key thing to note here is that although the congress members do argue over the specifics of such money expenditures, they do agree that the money should be spent. An “outlay” is an amount of money spent for any given thing, as though it is the amount that is “laid out.” This best fits the needs of this sentence in comparison with all of the other “discussion” related words that might be tempting.

The implication of the sentence is that nobody doubted René’s scholarly abilities. While a number of the options are generally acceptable, only “erudition” expresses the sense of having scholarly or intellectual achievements. The word literally is derived from the prefix “e-,” here meaning “away from” (in the sense of “not being”), applied to the base for “rude,” here in the sense of “uneducated” or “lacking culture.”

We can tell from the context of the sentence that we need to pick out a word with a positive connotation that means something like "aid." Neither "antipathy" or "anger" can be the correct answer because both of those words have negative connotations. "Succor," however, is a noun that means "assistance and support in times of hardship and distress." Because "succor" is the word that best fits the context of the sentence, "succor" is the correct answer.

Since Nathanael’s reason for objecting to the war are based upon his thought out opinions, it is not fair to say that they derive from cowardice, as is implied by a number of the options. Instead, the best thing to say in this sentence is that he desires peace. When someone is a “pacifist,” he or she believes that war or violence are not able to be legitimated. The word is derived from the Latin for peace and is found in English words like “pacify,” “pacific,” and “appease.”
