"Vex" means to agitate or bother. "Alleviate" means to relieve or lessen. "Burgeon" means to bloom or multiply. "Glean" means to pick out or collect. "Incite" means to encourage or provoke.

"Exacerbate" and "aggravate" both mean to infuriate or make worse. "Appease" means to satisfy or pacify. "Contort" means to disfigure or distort. "Oscillate" means to change back and forth. "Patent" means to secure a copyright on an invention. 

"Infuriate" means enrage or make someone angry, so "enrage" is the correct answer. None of the other answer choices are close in meaning to "infuriate": "grovel" means beg or crawl on the floor while begging; "indicate" means designate or mark; "pursue" means continue or follow; and "endorse" means approve or support.

When someone detests another person or thing, he or she does not merely dislike it but instead has an intense hatred for it. For that reason, the weaker answer choices like “dislike” and “disapprove” do not really capture the sense as does “abhor.” Someone “abhors” something or someone when he or she is disgusted by it or has a strong hatred for it.

“Placate” means assuage, or give someone what they want to make them feel better, so "soothe" is the correct answer. As for the other answer choices, “exacerbate” means make worse, intensify, or heighten; “eradicate” means completely destroy; “supplant” means replace; and “regress” means go backwards or return to a former state.

To "mourn" something means to express sadness regarding that thing. Now, do not be tempted by options like "bellow" (meaning, to shout loudly) or "whine." Although the mourning person may make various kinds of sounds, the essence of mourning is being sad. To "lament" something, however, is to express one's sadness just like someone mourning. This is a good synonym, given the options.

“Impair” means weaken, damage, or have a negative effect on. "Fortify” means reinforce and make more secure; "postulate” means posit, or state an unsupported point to consider as the start of a hypothetical argument; "renounce" means swear off one's association with; and "vex" means annoy.

“Forsake” means desert or renounce. “Preempt” means to act in advance of something else in order to stop that thing from occurring; “slander” means say bad, false things about something to damage their reputation; “satire” means mock something by adopting its style in a humorous way; and “patronize” means interact with in a condescending manner.

“Exonerate” means release from blame, free from guilt in court, or "acquit." As for the other answer choices, “condemn” means heavily criticize or punish; “convict," when used as a verb, means demonstrate in court that someone committed a crime; “prosecute” means start legal action against someone; and “postulate” means posit.

If someone succumbs, it means they yield or surrender; an example is succumbing in battle.
