"Twist" is the best answer choice. "Contort" means to twist, bend, or draw out of shape. 

"Infuse" means to inject, so "inject" is the correct answer. You may have been able to associate the two words based on their shared "in-" prefix, which in each does not function as a negative prefix but instead means inward.

Something that is preserved for "posterity" is preserved for future generations to enjoy, so "future generations" is the correct answer. For clarification, "ancestors" are forefathers or, more generally, the people who came before us, and "acumen" means insight or shrewdness.

"Incompetent" means incapable of doing something, so "inept," a word which means unskilled, is the correct answer. For clarification, "formulaic" means trite or following a standard format, "useful" means practical, "appropriate" means suitable, and "inappropriate" means improper.

"Consensus" means a unanimous agreement or an accord, so "accord" is the correct answer. For clarification, "unanimous" means concordant and specifically refers to a situation in which all parties agree to something; "adversity" means hardships or difficulties that need to be overcome, "adept" means skilled, "candor" means honesty or frankness, and "control" means dominance.

"Distasteful" means unpleasant. "Agreeable" means pleasant, so it is an antonym, not a synonym, of "civil," and cannot be the correct answer. None of the other answers are close in meaning to "distasteful": "praiseworthy" means of high quality or worthy of praise or worrisome, "well-mannered" means having good manners or polite, and "excessive" means more than is necessary or too much.

One can infer that "dissatisfied" means not satisfied because it is a combination of the negative prefix "dis-", which means not, and the word "satisfied." "Unhappy" is the answer choice that is closest in meaning to "dissatisfied," so "unhappy" is the correct answer.

"Recall" means to remember.
