“Genuine” and “bona fide” do not work when we consider the second part of the sentence about “foreign” and “from a neighboring country. Though “mitigated” is similar to “migrated,” note that these two have very different definitions. “Mitigate” means to make less severe. “Aboriginal . . . appropriated” is the correct answer.

If someone is “captious,” they tend to find fault with everything. “Complacent” means overly content. These could possibly describe the judge, but these do not inherently apply. “Discretionary” means to have the power to act according to one’s own judgment. “Discretionary . . . absolve” is the correct answer.

“Bawdy” has a negative connotation, but it doesn’t fit here. The definition of “bawdy” is inappropriate or obscene. “Discombobulated” and “absquatulate” are pseudo-Latin words that may sound complex, but their definitions are simple. “Discombobulated” means confused. “Absquatulate” means to run off with something. Together, these form the correct answer.

“Extant” means that something old is still around. It is not a bad fit, but there is nothing else mentioned in the sentence to say the movement has been around a long time. “Grassroots” means involving the common people. “Abstain” is to refrain from consuming. Together, these form the most accurate answer.

“Encipher” means to convert into code. “Limpid” is the opposite of the word we want. “Abstruse” means intellectually challenging. “Decipher” means to discover the meaning of, or crack the code. These last two words form the correct response.

The old man seems to be unwilling to change his lifestyle. Even more appropriately, he seems to be unwilling to improve his lifestyle. Hence, the best option is "amend", meaning to improve or change for the better. As regards his attitude, we could say that it is hard and durable as a rock—unchanging indeed! Hence, the word "obdurate," which comes from Latin roots for "hard," is the best option.

The first blank of this sentence is clearly a synonym that is related to the word "dormancy." This word comes from the Latin "dormire," meaning to sleep. We see the same base in English words like "dormitory" and "dormant." The word "quiescent" is a synonym for "dormant." It comes from the same root as "quiet" but also can mean to be still or unmoving. At last, however, Peter's rage "came forth." The word "erupted" works very well for this, for from its very roots it means to break out. This sentence makes Peter's rage out to be almost like a dormant volcano, just waiting to erupt!

“Impugn” means to challenge something you believe is wrong. “Proletarian” and “destitute” have the opposite definitions of what we need. The correct answer is “acclimate . . . erudite.”

If the professor were clear about the exams, then the students would be inclined to place more blame on themselves. For this reason, “explicating” can be eliminated. “Inculpable” means blameless, so this word doesn’t work given the context. To “equivocate” means to be ambiguous or unclear; this coupled with “accountable” is the correct answer.

"Revered" is the option that makes sense, as it matches the adjective directly preceding it. The choice "navigate" is the only verb that makes sense in the context of the harsh terrain.
