“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.

The word "dispute" can be used as a noun or as a verb. As a verb, it means to disagree about something, to debate about something, or (at least) to discuss something because of disagreement. Thus, we can say, "Katherine disputed the claim that her computer needed a new screen. She knew that something else was wrong with it and therefore tried to convince her brother not to buy the expensive new display." The word can also be used as a noun to describe the actual act of debating. Thus, there can be "a dispute" between two people—meaning that there is the activity of disagreeing and debating. The best option here "discuss," which is closest to the proper meaning of "dispute" used as a verb.

This question could be confusing, for it is using "trouble" as a verb. We often think of the noun "trouble," which means problem or difficulty. We also can say something like, "The loud sound troubled her, and she could not sleep." This means that it bothered her. Sometimes, we do say "a trouble" in a way similar to a bother (or, at least, "a bothersome thing").

For this question, you must be very careful. While a tree is a kind of plant, it is not synonymous with the word. Likewise, while plants do grow, the word "grown" is not appropriate either. It is neither synonymous nor the same part of speech. Instead, "plant" is being used here as a verb. When you "plant your feet on the ground," this means that you place them firmly on the ground. Thus, the simple word "place" is the best option!
