Be careful on this question! The word "compact" can have two meanings that are pretty different. It can mean dense. Thus, a compact load of laundry is very densely packed. (The option "heavy" is a trick, trying to make you confuse being dense with being heavy.) The other meaning is "agreement." A "compact" is an agreement between two or more people. (Think of the Mayflower Compact that you have perhaps learned about in history class. This was an agreement among the settlers of the Plymouth colony.)

The word "central" can be used to mean in the middle. It can also mean very important. For example, we might say, "She was the central figure in the whole project." This doesn't mean that she merely was in the middle point of the group. She was the most important person involved. (The idea of being central in this sense does come from the general awareness of something being "in the middle" being important often. It is important to see that this involves some changes in meaning.)

When we are "inspired" by something, that thing makes us feel filled with hope. An inspirational speech makes us want to go and be the best that we can be. In a way, such a speech "moves" us—it moves our emotions at least. The word "moving" can be used to talk about physical movement. It can also be used to mean "inspirational" or something that brings out a person's emotions. It is in this sense that it is the correct answer for this question.

The verb "to join" can be used to describe the action of entering a group. For instance, when someone "joins a book club," he or she becomes a member of that group. This meaning of "to join," however, is based on the more basic meaning—to connect. Thus, you can say, "He joined together the two sticks using glue."

When something is decent, it is "okay" or even respectable.  Sometimes, we use this to describe someone's personality: "He was a decent man."   This means that he was a good man—or at least good enough and honest.  Sometimes, we can use the word to mean "enough" or "an adequate amount."  For example, you could say, "He ate a decent amount of food."  This means that he ate an acceptable amount of food.  It isn't too much, though it is definitely not too little.

Do not be tricked by a question like this! When someone is "kind," he or she is likely nice and helpful. However, this does not mean that he or she is happy or "bubbly." You can be kind without being overly happy. This question is using "kind" in the sense of meaning a particular category. Thus, we say, "Chocolate is a kind of candy." This could also be said, "Chocolate is a type of candy."

The word "leak" can have several meanings (though they are related). Whenever a substance "leaks," it oozes out from its container. Thus, you can have leaky pipe, a leaky tire, or even a leaky bottle of shampoo. The word can also be used in the sense of "leaking a secret." This is the way that the word is being used in this question. None of the options pertain to leaking physical substances. The word "divulge" means "to tell information that should have been kept secret." It is like the information leaked out from its secrecy!

The word "severe" can be used either to describe a personality trait or to describe something more general. A person is "severe" when he or she is harsh, mean, or strict. A thing or event is "severe" when it is terrible, painful, or very strong. Thus, a severe storm is a very strong storm. The only option that expresses one of these meanings is "intense." Whenever a storm is very strong, it is intense.

The word "ground" can have multiple meanings. Yes, it can mean the physical ground beneath your feet. It is also a form of the verb to grind. Thus, when something has been "ground up," it has been crushed into little pieces. When we "pulverize" something, we smash it into little pieces, almost like dust. Therefore, among the options provided, only "pulverize" is a good synonym. Several of the options are traps—dirty and low, especially. These might describe aspects of the physical ground. They do not, however, function as synonyms for "ground" in this sense.

The word "labor" can be used as a noun meaning work. When used as a verb, however, it emphasizes the difficulty involved with a given attempt to work on something. Thus, it basically means to work very hard at something. Therefore, the only option that is acceptable is "struggle." If you said, "I labored at the task all day," this could be translated, "I struggled very hard all day at the task."
