"Legitimate" is a word that can be used as either a verb or an adjective, but because all of the potential answer choices are adjectives, we will need to consider "legitimate" as an adjective. When used as an adjective, "legitimate" means allowed by the law or rules, so "lawful," which means legal or authorized, is the correct answer. "Illegal" is an antonym of "legitimate" and "lawful"; it means unlawful and in violation of the rules. None of the other answers have meanings related to that of "legitimate": "decisive" means conclusive or crucial; "lucid" means clear; and "costly" means expensive.

"Significance" means importance, so "importance" is the correct answer. None of the other answer choices are close in meaning to "significance": "connection" means a relationship or link between two people, ideas, or things; "hatred" means extreme dislike or ill-will; "necessity" is something that is required or needed; and "exile" means someone who has been expelled from their home country and is not allowed to return.

"Magnitude" means size or extent. "Morality" means ethics that distinguish between what is right and wrong. "Swiftness" means quickness or agility. "Goal" means objective or target. A "garden" is a patch of land where plants and food are grown.

Since "vocation" is a job, we need to pick out another word that means "job." While "vocation" looks like "vacation," the two words have very different meanings, so "vacation" cannot be the correct answer. Similarly, "income" refers to money that is earned from a job, but not the job itself, so it isn't the correct answer either. "Occupation," however, means profession, and since it is the answer choice closest in meaning to "vocation," "occupation" is the correct answer.

"Expansion" means growth.

"Festival" means celebration.

An "admission" is a confession. "Destination" means the end of a journey. "Council" is a decision-making body. "Opinion" is a person's viewpoint. "Pause" means a temporary stop or break.

"Interpretation" means the explanation of an idea, concept, or viewpoint, so "explanation" is the correct answer. None of the other answers are close in meaning to "interpretation": "bribery" is the act of giving money to an official in order to influence a government decision; "memory" is an event or activity in the past that a person remembers; "winter" is the season of the year in which the coldest weather is experienced; and "company" is a business or a commercial institution.

The definition of "contemplation," the noun form of "contemplate," is deep consideration or thoughtful observation. "Reflection" is the best answer choice, as it means deep thought.

"Disclosure," the noun form of "disclose," is the correct answer. "Exposure" and "disclosure" both mean the act of revealing or making known.
