A "sanctuary" is a place of safety or refuge, especially when surrounded by an unsafe environment. Similarly, a "haven" is a place of security, so "haven" is the correct choice. Just to be thorough, let's look at the rest of the choices. "Peril" is synonymous with danger, so it conveys the opposite of safety. As you might be able to tell by dissecting the word, "companionship" refers to the state of having a companion or friend. Finally, "opacity" is derived from the word "opaque," which describes materials that are not transparent or "see-through." Hence, opacity means impermeability to light and has nothing to do with "sanctuary."

"Terrain" is land. "Land" is the best choice because it is a part of the definition of the word "terrain."

The prefix "spec-" means to see or to look at. A “specimen” is an example to look at. In this sense, it is closest in meaning to “sample.” To provide further help, an “integer” is a number; “fusion” is a process of joining things together; “dogma” is an established belief system; “refractory” means stubborn or disobedient. 

Start by looking at the word "declaration" to find any possible base words that you might know. Certainly, you know "declare," which you would use in a sentence like, "I declared my feelings to her so that she would know how much I loved her." This means that you told or announced your feelings to the girl of your heart's desire. A "declaration" is the message that is declared; the words themselves are the declaration. Generally speaking, the word "declaration" is used to describe an official announcement, such as a "Declaration of Law 4832B," or something similar. Among the options provided, only "announcement" matches this closely enough. Perhaps you will be confused by "advertisement," for an advertisement "shows" something to someone else. However, the meaning of "announcement" is closer to the general sense of "declaration."

A "haven" is a refuge or a place of safety, so "refuge" is the correct answer. None of the other answer choices are close in meaning to "haven": a "vehicle" is a thing used to transport or move things or people; "legislation" refers to laws or bills enacted by a governing body; "pollution" is the addition of a toxic or harmful thing to something; and a "station" is a stop for public transportation or a building that serves as a central location for a specific group or activity.

A calamity is best described as a disaster or unfortunate event.

"Commotion" means a state of chaotic and noisy confusion. "Uproar" is the word that most closely matches this definition. "Punishment," "conquest," and "restoration" are all unrelated terms.

“Preamble” means before the main story, so it is similar in meaning to “introduction.” The prefix "pre-" means before. To provide further help, the “conclusion” is the end; the “epilogue” is the part of the story that comes after the main story; a “dissertation” is an academic essay submitted at the end of university; a “thesis” is the main argument of an essay.

A "pamphlet" is a small booklet or packet, so "booklet" is the correct answer. "University" is a school of higher learning. "Quarrel" is a fight or a disagreement. "Connection" means bond or link. "Restaurant" is a place where people go to have food cooked for them and eat it.

An “abode” is a home or where someone or something lives. If you are “in your abode,” you are “in your house.”
