“Glimmer” is a word that can be used as a verb or a noun, but because all of the answer choirs can be used as verbs, we will need to consider “glimmer” as a verb. When used as a verb, “glimmer” means gleam, so we need to pick out an answer choice that means something like gleam. That means that “beam” cannot be the correct answer, because “beam” can mean shine in a bright way, and because “glimmer” specifically refers to a more faint kind of shining, “beam” cannot be the correct answer. “Twinkle,” however, is a word that when used as a verb means glimmer, and because “twinkle” is the answer choice closest in meaning to “glimmer,” “twinkle” is the correct answer.

"Concept" is a noun meaning "an idea of what something is or how it works," so we need to pick out an answer choice that means something like "idea." While "confident" might sound like the correct answer because both "concept" and "confident" start with the syllable "con-," "confident" means "feeling or showing confidence in oneself; self-assured," or "feeling or showing certainty about something." Because "confident" does not mean the same thing as "concept," it can't be the correct answer. Since "idea" is the answer choice closest in meaning to "concept," "idea" is the correct answer.

"Esteem" is a word that as a noun, means "respect and admiration, typically for a person," and as a verb, "respect and admire." So, we need to pick out an answer choice that means something like "respect," as a noun or a verb. "Team" might seem like a potentially correct answer because "esteem" contains the syllable "teem," which sounds the same as"team;" however, "team" does not mean the same thing as "esteem," so it cannot be the correct answer. Since "deference" means "humble submission and respect," "deference" is the answer choice closest in meaning to "respect," and thus the correct answer.

“Fusion” is a noun that means “joining two or more things together,” so we need to pick out an answer choice that means something like “blending” or “joining.” That means that “separation” cannot be the correct answer, because “separation” means “the division of something,” making it an antonym, not a synonym, of “fusion.” “Combination,” however, is a noun that can mean “a joining of different parts,” and because “combination” is the answer choice closest in meaning to “fusion,” “combination” is the correct answer.

“Vigor” is another word for strength or energy, so "strength" is the correct answer. To provide further help, “intelligence”  means how smart you are, a “career” is a job you mean to do for a long time, and “research” means study in a methodical way. 

An “hypothesis” is an idea that needs to be tested to see if it is true or not. To provide further help, a “novice” is a beginner or someone new to something; a “professor” is a teacher at a college or university; a “science” is a branch of learning devoted to observing phenomena and testing ideas via experimentation; and a “menace” is someone or something who is threatening, scary, or dangerous.

A “pest” is something that is annoying, or a “nuisance.” To provide further help, “piece” means a part of a larger whole; a "whisper" is something said in a soft, quiet voice, a "secret" is some piece of information that you don't tell anyone, or that you share with very few people; and a "pet" is a domesticated animal kept for entertainment and companionship.

"Jumble," when used as a noun, means clutter, muddle, or mess, and when used as a verb, "jumble" means mix up in an untidy manner. The correct answer is "muddle," which when used as a noun means a mixed-up and confusing mess, and when used as a verb means confuse or mix up into a disorganized mess. As for the incorrect answer choices, "blunder" means make a mistake and a "blunder" is a mistake or an error.

Glee means Joy.

"Conflict" is a disagreement; Agreement is a consensus; Profession is a job; Transaction is an exchange; and Champion is a winner.
