The "aud-" in "audience" derives from the same Latin roots as "audible" (able to be heard) and "audio" (recorded sound, often specifically the sound that often accompanies video). So, since "aud-" means having to do with hearing, it makes sense that an an “audience” is a group of people who are listening to and watching a show or reading a text-based work, making "listeners" the best answer choice. “Musicians” are people who play music and “performers” are people who perform in some sort of show or entertainment. So, an “audience” listens to the “musicians” or watches the “performers.”

The "fract-" part of "fracture" stems from the same roots as the words "fraction" (a portion of a whole) and "frangible" (breakable), so it makes sense that "fracture," when used as a verb, means break something hard. The word is often used to describe breaking a bone. "Break" is thus the answer choice closest in meaning to "fracture." As for the other answer choices, "include" means consider as part of a group; “bemoan” means complain about; “describe” means use words to share information about the characteristics of something or someone; “represent” means show using a visual or textual medium or stand in for.

The prefix "du-" means relating to two of something; it is found in words like "duet" (song for two singers or musical piece for two performers), "dual" (having two of something), and "duel" (a fight between two people in which specific rules are followed, often arranged because one competitor has somehow deeply insulted the other). Thus, it makes sense that "duo" means a pair. “Triplets” are sets of three of the same thing or three babies born at the same time to the same mother; a “trifecta” is a group of three great things working together; a “quartet” is a team of four.

The prefix "extra-" means beyond or outside and the "-terre-" part of "extraterrestrial" comes from the root "terra," meaning earth, so it makes sense that an “extraterrestrial” is a living creature originating from beyond earth, or an alien. A "human" is a creature of the species homo sapiens, also known as a person, “deity” is another name for a god or goddess; an "angel" is a very virtuous person or a being believed to be a spiritual attendant to the Christian god pictured depicted as a person with a halo and feathery wings; a "devil" is a rascal, an evil person, or an evil spirit, often represented as being or wearing bright red with horns and a tail.

The prefix "co-" means together, so it makes sense that a "collision" is a crash or impact. “Hint” means suggest something indirectly; “grasp” means grab onto; “assist” means help; “amend” means change, edit, or fix.

You may use the word "animated" most frequently to describe cartoons or other "animated" television shows and movies. This word, however, means much more than merely cartoons and so forth. The word "animated" comes originally from the Latin word "anima" for soul. An "animated" being is one that is thought to have some kind of soul—though this is a very complex matter. Ancient thinkers thought that plants and animals had souls, as well as humans, since they could all somewhat "act on their own." Something that is "animate" is self-moving or merely moving, whereas an "inanimate" object is one that is not moving. Therefore, to be "animated" is to be lively, vibrant, moving, energetic, and so forth. Therefore, "energetic" is the best option among those provided.

The word "multitude" has the root "multi-" in it, meaning many. You know this from words like "multiply" and many words that have "multi-" before them (like "multi-faceted" and so forth). The word "multitude" can be used as an adjective, meaning something like a lot or many—"a multitude of flowers." However, it can also be used as a noun meaning many things or a gathered group of many things. For instance, "The multitude gathered in the town square." This can mean either something like "the common mob" or, perhaps, just "a crowd."

You can tell that your answer will have to follow the noun version of "multitude" because all of your options are nouns. The only option that directly captures the sense of a group is "crowd." You might be tempted to think of "multitude" as related to "majority," which would lead you to choose either "election," "vote," or (perhaps) "politician." Do not be tricked in this way. "Crowd" is by far the best option provided.

The "grad-" part of "gradual" comes from the Latin for step or go; the English words "grade" (level of quality given to work being analyzed) and "gradation" (step or different level in a greater whole) also come from this same Latin word. It thus makes sense that “gradual” means step-by-step or moving along slowly but consistently. This means that "slow" is the best answer choice. As for the other answer choices, "hurried" means happening quickly or rushed; “reckless” means not careful and potentially causing trouble due to lack of care; “wanton” means random; and “dynamic” means energetic and active.

To solve this problem it is necessary to consider the meaning of the root of the word "scribe." The root word -scrib- means write, so a "scribe" is a writer. To "inscribe" is to write in for example. 

To solve this synonym you have to examine the roots in the word "incredible." -cred- means believe and in- means not. So the word "incredible" means not believable, which is the same as "unbelievable." Notice here how the prefixes in- and un- both function the same way, they take the original meaning of the word and negate it causing it to mean the opposite. So "unwelcoming" means not welcoming.
