This sentence tells us that some students misunderstood a writing prompt and focused their essays on the wrong topic, so it would make sense for the teacher to suggest that they make significant changes to their work before turning it in. We thus need to pick out an answer choice that means something like "make significant revisions to a piece of written work." In this context, "revise" means make changes to something based on feedback or learning new information, so "revise" is the correct answer. While one might "write" or "finish" a draft, the sentence doesn't give us any reason to think that these drafts are unwritten or unfinished, so neither of these answer choices can be correct. "Scribble" means scrawl or write in a messy manner, so it doesn't make sense in the blank and cannot be the correct answer either. "Omit" means remove, so while one might omit information, sentences, or paragraphs from a draft of an essay, one would not omit the entire essay; that doesn't make sense. So, "omit" cannot be the correct answer either.

As we know that many viewers are "surprised" by the gymnasts' flexibility, the people in the sentence are most likely "awed," or amazed, by the flexibility of the gymnasts. The other answer choices don't make sense in the context of the sentence—"confused" means perplexed because one is unable to understand something; "considerate" means thoughtful and polite; "perturbed" means annoyed, and "elated" means extremely happy.

We can infer that because Rita “couldn’t eat [the fruit]” after “[leaving] it on her counter for a week;” the fruit must have gone bad. So, we need to pick out an answer choice that means something like “go bad” or “become rotten.” While “spoiled” and “ripened” might each look like a potentially correct answer, “ripened,” when used to describe food, means “become ready to eat,” so “ripened” cannot be the correct answer because it would not make sense in the sentence. If the fruit were ready to eat at the end of the week, the sentence wouldn’t say “[Rita] couldn’t eat [the fruit].” “Spoiled,” however, is a verb that means “unfit for eating” when referring to food, and because “spoiled” best fits the context of the sentence, “spoiled” is the correct answer.

The correct answer is "observe," which means to watch carefully and pay attention to. "Neglect" and "ignore" are opposites of "observe." "See," a verb which means look at, could make sense, but "observe" is the better answer choice because if you observe something, you watch it carefully and pay attention to it, and this care and attention are not part of the meaning of "see."

The correct answer is "reduce." "Reduce" means make smaller or lessen. The other words can all make sense grammatically in the sentence, but reduce makes the most sense given that the sentence begins with the phrase "To help the environment."

The context of the sentence tells us that the doctors worked tirelessly to bring the man back to consciousness, and this is the meaning of the word “revive.” In English, the root "viv" means life or living as in “revive,” “survive,” “vitality,” and “vitamins." None of the other answer choices make sense in the blank: when used as a verb, “convict” means successfully bring criminal charges against in court, and when used as a noun, a "convict" is a criminal; “expose” means reveal; to “conjecture” is to guess; and “supplant” means replace.

When you put something off to be continued later, you “postpone” it. So, because the tennis match was stopped because of the rain and planned to be finished the next day, the correct answer is “postponed.” The word “outlawed” means banned or not allowed, and “restored” means put back into original condition.

The context of the sentence tells you that the secretary can rotate his chair so that he can focus on the whole office. You are therefore looking for an answer choice that has a similar meaning to "rotate." The correct answer is therefore "swivel." To provide further help, "demolish" means destroy, tear down; "replenish" means refuel, restock; "dispose" means throw away; "undulate" means wave.

In this sentence the teacher asks the student to go home and change his work. Based on the structure of this sentence you know that the blank word must be a verb that means "change." The correct answer is therefore "alter." To provide further help, "postpone" means delay until later; "sprint" means run fast; "conceal" means hide; "prefer" means like more than another thing. 

The children who are the subject of this sentence are doing something happily by the side of the river in summertime. From context we can reasonably infer that the children are playing, so you need to find an answer choice that means something similar to "play." The correct answer is "frolic" which means to play, to have fun. To provide further help, "labor" means work; "consume" means eat; "retire" means stop working, stop doing something; "panic" means to freak out.
