The word "contest" has multiple meanings, one of which is a clash between two entities. (This one is pronounced "CON-test.") It can also be used as a verb ("con-TEST") that means to dispute or question a decision and ask that it be reconsidered. "Question" is thus the correct answer.

"Function" can be used as either a noun or a verb. When used as a noun, "function" means purpose; when used as a verb, "function" means work properly. So, "work" is the correct answer. “Demand” means forcefully ask or say something has to be done.

Do not confuse the word "assault" with "insult." A number of the wrong options are meant to tempt you to make this mistake. Do not fall for it! The word "assault" means to attack physically, or merely to attack. An army can assault a city, and a person can assault another person. In both cases, we are referring to some kind of physical attack. Sometimes, the word is used in a secondary sense to describe any kind of attack, like a "verbal assault." Still, the general meaning that is retained is that of attacking. Therefore, the best option among those provided is "attack."

“Prattle” is a word that can be used as a noun or a verb, but because all of the potential answer choices are verbs, we will need to consider “prattle” as a verb. When used as a verb, “prattle” means “talk at length in a foolish way,” so we need to pick out an answer choice that means something like “talk in a foolish way.” That means that “enunciate” cannot be the correct answer, because while “prattle” and “enunciate” both have to do with speech, “enunciate” means “say or pronounce clearly.” So, because “enunciate” is very distant in meaning from “prattle,” it cannot be the correct answer. “Jabber,” however, is a word that means “talk rapidly about nonsense” when used as a verb, and because “jabber” is the answer choice closest in meaning to “prattle,” “jabber” is the correct answer.

To "whirl" means to turn around in a circle quickly and repeatedly, so "spin," which also means turn around in a circle quickly and repeatedly, is the correct answer.

The word "noble" has several meanings. It can be used as a noun for a particular class of people. The "nobles" are a class of people who inherit rights from their parents, often in older countries in Europe. The "nobles" or "nobility" include dukes, barons, and other kinds of people like this. (They are sometimes called the "gentry"—sort of like "gentlemen".) They are not necessarily rulers. Therefore, we need to look for another meaning for "noble."

The word can also be used as an adjective. Among the meanings of this use of "noble," we find "honorable" or "virtuous." In these cases, we would say things like, "He was a noble man who helped all of his friends in need," or, "I gave my money to a noble cause to help the poor." Therefore, the best option is "honorable", not "politician" or "ruler." (Even "wealthy" is wrong. Someone can be a noble but not necessarily be wealthy—though the two often go together.)

The word "splinter" can be used either as a noun or as a verb. As a verb, it indicates the action of breaking something—as when you splinter a piece of wood into pieces. As a noun, it is used to describe the product of such breaking. Thus, a splinter of wood is a small piece of broken wood. It gets its name from the fact that it is such a small piece. The word "splinter" is not synonymous with "wooden." The word "shard" is synonymous with "splinter," however. A "shard of glass" is a kind of splinter of glass.

In this question, the word "reward" is being used as a verb. You can eliminate the possible noun option "wealth." While rewards might be sums of money, they are not essentially a matter of wealth. Instead, they are awards, prizes, or honors given for some reason. As a verb, "reward" can mean, to give (an award), but it can also have the sense of repaying someone. For example, you would say, "For his hard work, he was rewarded with a trip to the movie theater." This is the sense used for this question.

When used as a noun, "alert" indicates a kind of warning. As a verb, it means to warn or to make aware. Thus, you would say, "I alerted him about the dangerous ice on the stairs before he left the building." This means that you warned him about it.

For this question, you must realize that "free" is being used as a verb, as when you say, "I freed the trapped bird." Therefore, do not be tricked by the trap answers "minimal" and (especially) "inexpensive." These are trying to make you think of the adjective forms of "free;" If this question were using free in that way, then it would not be "inexpensive" but "costless." Free things are not merely inexpensive; they cost nothing. Therefore, the best option is "release," for when you free something, you release it.
