The key to solving this problem is the use of the word "readers." This should help you choose the correct answer, "The author's writing . . . " because "author," "writing," and "readers" go together better than any of the other answer choices. 

To solve this problem you simply need to determine which of these answer choices is the most likely reaction to a game that is boring. The correct answer then is " . . . so we left at halftime." Additionally, "compelled" means forced, pressured; "outcome" means result.

You are told in the second part of the sentence that the subject of this sentence "must have access to water" this tells you that the first part of the sentence is likely about the ability of something to grow when given water. The correct answer is therefore "If you want this tree to grow . . . " The answer choices that read "The plant is likely to perish . . . " and "The tree is slowly dying . . . " could work if there was a semicolon in this sentence, but because there is not they do not fit the context. Additionally, "perish" means die.

To solve this problem you first need to know that "intolerant" means not tolerant, not accepting or patient. So, if the teacher is "intolerant" it makes sense that she would have " . . . little patience for her students." The other answer choices would all make sense if the teacher was described in positive language, not the negative adjective "intolerant."

To solve this problem you need to determine what would likely happen if someone kept spending more money than they have. The correct answer is that their " . . . debts [would keep] climbing." The other answer choices either contain inappropriate conjunctions, such as "yet" or else contain words that could not be used to describe someone who spends more money than they have. "Miserly" means cheap, stingy, not generous with money; "frugal" means responsible with money, not likely to spend a lot of money.

To solve this problem you obviously need to know the definition of the word "jubilant." "Jubilant" means very happy and overjoyed. So, which of these answers is a reason why children might most likely be very happy? The correct answer, of course, is because " . . . it is a snow day."

To solve this problem you first need to know that "massive" means very large, gigantic. So, which of these answer choices fits with the description of something as "massive"? The correct answer is " . . . towered above the houses." If you "tower above" something you are much taller than it.

To solve this problem you simply need to figure out which of these answer choices would most likely be related to a very cold house. The correct answer is "The heater is broken . . . " All the other answer choices would either require a negating conjunction like "but" or "yet" or else don't make sense in context.

To solve this problem you need to determine why the subjects of this sentence would be unable to get any bread. The most likely answer is because "The bakery is closed . . . " Some of these answer choices might seem right at first glance, but contain incorrect pronouns. Such as "They have no money . . . " If "they" was replaced with "we" this answer would make sense. You need to always be aware of pronoun continuation in sentence completion problems.
