"Alias," when used as a noun, means "a false or assumed identity." The word can also be used as an adverb "used to indicate that a named person is also known or more familiar under another specified name." (The adverb functions in the same way as the phrase "also know as," but is specifically used to discuss real and assumed names.) So, we need to pick out an answer choice that has to do with names, specifically, with fake or assumed names. Since "fake name" is the answer choice closest in meaning to "alias," it is the correct answer.

The magnitude of an object or person refers to their size and often suggests vastness.

"Perseverance" is a noun that means "steadfastness in doing something despite difficulty or delay in achieving success." While "bravery" might look like a potentially correct answer, because someone who is brave might also demonstrate perseverance, "bravery" does not mean "perseverance," so it cannot be the correct answer. "Persistence," however, is a noun that means either "firm or obstinate continuance in a course of action in spite of difficulty or opposition" or "the continued or prolonged existence of something." Because "persistence" is the answer choice closest in meaning to "perseverance," it is the correct answer.

If there is pandemonium, it means there is a high level of commotion or chaos.

"Allegiance" is a noun that means "loyalty or commitment of a subordinate to a superior or of an individual to a group or cause." That means that "rebellion" can't be the correct answer, because "rebellion" means "an act of violent or open resistance to an established government or ruler" or "the action or process of resisting authority, control, or convention," so "rebellion" is an antonym of "allegiance." "Loyalty," however, is a noun that means "the quality of being loyal to someone or something," so "loyalty" is the correct answer because it is the answer choice closest in meaning to "allegiance."

"Agony" is a noun that means "extreme mental or physical pain." So, we need to pick out an answer choice that means something like "extreme pain." That means that "comfort" can't be the correct answer, because "comfort" means "a state of physical ease and freedom from pain or constraint" or "consolation for grief or anxiety." So, "comfort" is an antonym of "agony." "Torment," however, is a word that when used as a noun means "severe physical or mental suffering" or "a cause of such suffering," so "torment" is the correct answer because it is the answer choice closest in meaning to "torment."

"Clarity" is a noun that can mean "the quality of being clear, in particular," "the quality of coherence and intelligibility," " the quality of being easy to see or hear; sharpness of image or sound," "the quality of being certain or definite," or "the quality of transparency or purity." So, we need to pick out an answer choice that means something like "clearness." That means that "obscurity" can't be the correct answer, because "obscurity" can mean "the quality of being difficult to understand," so "obscurity" is an antonym of "clarity." "Transparency," however, is an adjective that means "the quality of being able to see through something" or "the quality of being readily understood," so "transparency" is the correct answer because it is the answer choice closest in meaning to "clarity."

"Prejudice" is a word that when used as a noun defined as "preconceived opinion that is not based on reason or actual experience" or "dislike, hostility, or unjust behavior formed on such a basis." So, neither "fact" nor "friendship" can be the correct answer, because they are each an antonym of "prejudice." "Preconception," however, is a noun that means "a preconceived idea or prejudice," and because "preconception" is the answer choice closest in meaning to "prejudice," "preconception" is the correct answer.

"Travesty" is a word that when used as a noun, means "a false, absurd, or distorted representation of something," and when used as a verb, means "to represent something in such a way." So, "praise" cannot be the correct answer because to "praise" something is to say good things about it, while to "travesty" it is "to produce a false, absurd, or distorted representation of something." "Mockery," however, is a noun that means either "derision; ridicule," or "an absurd misrepresentation or imitation of something." Because "mockery" is the answer choice closest in meaning to "travesty," "mockery" is the correct answer.

"Priority" is a noun that can mean "a thing that is regarded as more important than another," "the fact or condition of being regarded or treated as more important," or "the right to take precedence or to proceed before others." So, we need to pick out an answer choice that means something like "greater importance." "Precedence" is a noun that means "the condition of being considered more important than someone or something else; priority in importance, order, or rank," and because it is the answer choice that is closest in meaning to "priority," "precedence" is the correct answer.
