This question is using "field" in a way that you might not recognize at first glance. The word does indeed indicate a kind of physical field in which grass (and other things) might be found. The word can also be used as a verb. In this sense, we say things such as, "He fielded questions regarding the event." This means that the person received and answered the questions. (This is somewhat like a baseball catcher being in the field and catching balls—though, in this case, the "balls" are questions!)

We tend to think of being "buried" in terms of physical burial. Whenever someone dies, his or her body is buried in the ground. This means that it is placed under the soil. It is this general sense of "placing under" that is the root of the meaning being used here. Whenever someone "buries" his or her feelings, that person hides them—sometimes even from himself or herself. Hence, the word "buried" could have "concealed" for one of its synonyms, as it does in this question.

The word "bright" is a great example of how we metaphorically use language in everyday speech. We will sometimes say that someone is "bright" or that an idea is "bright," meaning that it is intelligent. Such "brightness" is like an "intellectual light bulb," helping to illuminate some topic with insight. Hence also, we will call someone "dim" when he or she is not very intelligent.

The word "critic" comes from Greek and Latin words that mean to judge. When we "critique" someone or something, we give an opinion about that person or thing. Likewise, a "critical remark" is one that judges something, generally negatively. The word can also mean important when used as the adjective "critical." For example, at a "critical time," it is necessary to judge something one way or the other. This actually comes from the idea of judgment mentioned earlier. Something is "critical" because it requires a judgment—right now. By extension, we say something is "critical" when it is "important."

The word "elevated" means, most generally, "higher than other things." Now, this most often is used to describe physical elevation—as in the elevated mountains in contrast to valleys and hills. However, it can also be applied to things that are elevated in the sense of being more noble or important. Thus, elevated discussion is discussion of important and noble things. Thus, among the words provided, the only option that directly recognizes such "heights" is "noble." Remember, "noble" not only refers to the person such as a prince or king. It also is an adjective meaning "excellent."

When something is "sleek," it is very clean and smooth. It is often used to describe the kind of smooth hair that a person or animal can have when we say that it is "slicked back"; however, this kind of clean and smooth appearance can also indicate that something is "in style" or at least elegant (as opposed to something that is a total mess). This is the way "sleek" is being used in this question, for the only acceptable option is "stylish."
