This sentence misuses the word "flout," which means to disregard/mock. Since the award belongs to the subject, it is unlikely that he would mock it. Instead, he is likely showing it off, which is the definition of the word "flaunt." The correct choice is, "He flaunted his award."

Note that a colon should not interrupt the main clause of this sentence.

This sentence misuses the word "proscribe," which means to forbid. The correct word here is "prescribe," which means to recommend. No punctuation is needed in this sentence because it is a simple sentence. The correct choice is, "The doctor prescribed some medicine for Misha's daughter."

This sentence misuses the word "shrunk." "Shrunk" is the participle form of the word "shrink," NOT the past tense form. You may say something like: "The shrunk shirt was no longer wearable" or "I have strunk the shirt," but NEVER "I strunk the shirt." The correct word here is "shrank." The correct choice is, "the amount of volunteers shrank." Note: the other choices cause issues in tense agreement/parallelism.

This sentence misuses the word "phenomena." The word "phenomena" is a plural noun. "The Wow! signal" is singular, so the correct word would be "phenomenon." Note: the use of the article "the" would not be appropriate because it would imply that the Wow! signal was the only thing that still confuses scientists, which is untrue. The correct choice is, "The Wow! signal was a phenomenon that still."

This sentence misuses the word "credulous," which means gullible. It is clear from the phrase "since he would always break his promises" that the sentence means not trustworthy. This is the definition of "credible," which is the correct answer.

This sentence misuses the word "invent," which means to create. What is meant in this sentence is the arrival, which is the meaning of the word "advent." No punctuation is necessary because this is a simple sentence. Technically, you could use commas to separate the phrase "like the GoPro," because it can function as a parenthetical expression: a phrase that explains more about a particular word or phrase in the sentence, but is not introduced by a relative pronoun; however, the correct punctuation is not available as a choice here. The correct choice is, "The advent of products like the GoPro have made."

This sentence misuses the word "affect," which is a verb meaning to change. It is clear from the context of the sentence, however, that a change (noun) is meant here. The word "effect" is the correct choice. Furthermore, there should not be a comma before "and" because "emotions and how we act" is not a list (lists contain 3+ items). The correct choice is, "demonstrated effect on our emotions and how we act."

This sentence misuses the word "bemused," which means confused. It is clear from the context of the sentence, however, that Kareem does not find Kelly's jokes funny. The word "amused," meaning entertained is meant here. Note that the phrasing "was not amused" is not passive voice here because "amused" is an adjective, linked to Kareem by the linking verb "was." The correct choice is, "was not amused by Kelly's awful jokes."

This sentence misuses the word "criteria," which is plural. The word "only" dictates that the word following it must be singular. The singular form of "criteria" is criterion. The correct choice is, "the test is the only criterion for the position."

This sentence misuses the word "ironic," which means contrary to what is expected. Since the latter half of the sentence states that other believed that she would obtain the part, it is most likely that "unfortunate," meaning not lucky, would be the correct choice since it is likely that people wanted Julie to get the part. The correct choice is, "unfortunate."
