The correct answer is "her." This pronoun refers to the subject, "she," which is singular and feminine, so the pronoun must also be singular and feminine. It also needs to be a possessive pronoun, since the pronoun describes something that belongs to the subject of the sentence ("her friend"). The only choice that fits these descriptions is "her," so it is the best choice. 

The correct answer is "its." This sentence requires a singular pronoun to agree with the subject, "apartment" which is singular, therefore, the choice "their," which is plural, is incorrect. The word apartment does not have a gender, so we do not use "his" or "her." That is why the best choice is "its."

This question is a simple interrogation of correct pronoun usage. The only possible correct answer is thus "her" since "Kathy" is the object of the second main clause. 

This question asks you to select the best answer based on context clues, and a knowledge of the most appropriate idiomatic expression in this case. While "solo" and "primary" could both be considered grammatically correct options, neither of these is a common business expression, whereas "chief financial officer" is a very common job title at companies of a certain size. While "boss" has a vaguely similar meaning to chief, it is to informal to be appropriate for use in this setting.

"Disorder and bad publicity" clearly would "hurt" or "damage" a company's standing. "Ameliorated" is a verb meaning to improve, and is thus an antonym of the correct answer. A company's standing is unlikely to be completely "removed" unless that company ceases to exist. "Opened" does not make sense in this context.

Here, we're looking for a noun that would refer to a detailed accounting of the company's financial "books" or records. The only word that makes sense in this context is "audit."

The sentence states that the subject did not want to become sick like his friends. "To catch the flu" means to become sick with the flu. "To catch sight of something" means to have your attention drawn to it; "make a mess" means to cause disorder and "have a rest" means to relax.

This sentence is talking about the possibility of flooding so could is the best answer. "Could" is used to express possibility. "Should" is used when giving advice. "Is" is a being verb.

"Should" is the correct answer because should is an imperative commonly used when giving advice. "Could" is used when talking about past abilities. While the question is talking about the advice his uncle used to give. "Would" is incorrect because "would" is commonly used when speaking about unreal situations or conditions.

"Take after" is the correct answer because it means to resemble someone. Here the sentence says the subject shares physical traits with his father like hair color and nose shape. "Go after" means to try and get something. "Look after" means to care for someone.
