Imagine that one of your best friends is very angry. To calm him down, perhaps you will agree with the opinions that he is stating, even if you aren't sure whether he is right. In this case, you tried to "placate" your friend. To "placate" is to soothe or calm someone who is angry or violently frustrated, especially by conceding to his or her point(s) of view. "Appease" refers to the same process, and is the right synonym to choose here. "Frustrate" and "attack" are incorrect because they describe actions that would only make an furious person more upset, and "congratulate" conveys appreciation of an impressive feat, not pacification of an irritated person or group.

"Copy" is a verb meaning reproduce or mimic, so the answer closest in meaning to "copy" is "mimic," a verb meaning imitate. Considering the other choices,  "maintain" is a verb that means support continually, "solidify" is a verb meaning make solid, and "return" is a verb meaning to go back to.

"Flaunt" is a verb meaning display overtly in order to garner attention, so the answer choice closest in meaning to "flaunt" is "show," a verb that means present, display, or demonstrate. Considering the other options, none are close in meaning to "flaunt": "hide," when used as a verb, means conceal or conceal oneself; "ignore" means willfully refuse to notice or pay attention to; and "accuse" is a verb meaning blame.

"Suggest" is a verb that means bring up an idea as an indefinite possibility, so the answer choice closest in meaning to "suggest" is "propose," which can mean put forth an idea as a possibility. Considering the other answer choices, none are close in meaning to "suggest": "agitate" means disturb; "irritate" means annoy; and "talk" means converse by using audible words.

When you "forfeit" something, you give up or lose that item. The other answer choices do not have the same connotations: "deprive" means to deny; "detach" means to forcibly remove; "secure" means to attach or fasten; and "debunk" means to expose something as false.

To "muse" means to ponder or think about something. The other choices are not as close in meaning: to "forge" is to create or etch; to "reminisce" is to fondly recall; to "recall" is to remember; and to "summon" is to call for or awaken.

When you "rouse" someone, you stir them into action. This is equivalent to "provoke" which means to awaken. The other incorrect answer choices indicate the following: to "mourn" or to "lament" is to grieve; to "hibernate" is to go into a restful state; and to "discover" is to find out.

"Spurn" means to reject with contempt.

The word "chastise" most nearly means reprimand. If a parent chastises a child for his or her behavior, for example, they scold or discipline the child.

The word "spurn" means reject. The best choice is "reject" because it is a part of the definition of "spurn." Considering the other choices, "corrupt" means cause someone to act immorally in order to benefit him- or herself when used as a verb or guilty of dishonest practices when used as an adjective; "generate" means create; and "scatter" means separate and drive off in different directions.
