“Quake” is a verb that means “shake or tremble,” especially when referring to the earth, or “shake or shudder with fear” when referring to a person. So, we need to pick out an answer choice that means something like “shake.” That means that “freeze” cannot be the correct answer, because “freeze” can mean “to become paralyzed with fear or shock,” making it an antonym, not a synonym, of “quake.” “Quiver,” however, is a verb that means “to tremble or shake,” and because “quiver” is the answer choice closest in meaning to “quake,” “quiver” is the correct answer.

"Camp" and "team" are synonyms. The word "camp" can be used to describe a side, a team, a particular group of people with a shared value or conviction. The other words do not have meanings closely related to camp.

"Trunk" and "box" can both refer to a receptacle used to store or carry items. The other words are not synonymous with "trunk." An "alternator" is a part of an "engine" (at least for cars).

"Wind" may be a noun (relating to air movement and weather), but it may also be a verb. As a verb, "wind" means to move in a twisting or spiral course. The verb "weave" means to turn from side to side while moving somewhere, and is an appropriate synonym for wind.

The verbs "bank" (when used as a verb) and "invest" can be synonymous, referring to the actions of a financier. The meanings of the other answer choices are not related to the word "bank."

"Current" and "airstream" can be synonyms, especially if the word "current" represents a stream of wind ("current" can also refer to the present time). The other words are not related in meaning to the word "current."

"Elite" and "exclusive" are synonyms referring to a select group (usually implying the selection is tied to excellence). The other words do not have related meanings. "Natural" means not artificial. "Audible" means perceptible through aural faculties.

An incarnation is the embodiment of a god, or an individual's lifetime.

"Glacial"can have two meanings: very cold or moving very slowly. ("Glacial"comes from the word "glacier," which is a huge mass of ice that moves extremely slowly.) Given that none of the answer choices are similar to the word "cold,"the best synonym is one that means slow.Thus, the best answer choice is "slow."
