In which sentence is the word fast used as an adverb?

The correct word to use in this context is "There."

Therefore, the corrected sentence would be: "There are three things to remember for the test: vocabulary, grammar, and spelling."

The options A. ":", B. "For," and D. "and" are used correctly in the sentence. It is only the incorrect use of "Their" that makes the sentence grammatically incorrect.

The contraction "they're" combines the pronoun "they" with the verb "are." It is a shortened form used to represent the combined words in a more concise and informal manner. The apostrophe in "they're" replaces the missing letter "a" from "are."

The other options are not the correct contractions for "they are."

Option A, "their," is a possessive pronoun indicating ownership. It is not a contraction for "they are."

Option B, "the're," is not a valid contraction in English. The correct form is "they're."

Option D, "No Contraction used," is not the correct answer because "they're" is the appropriate contraction for "they are."

Therefore, the correct contraction for "they are" is "C. They're."

"The men and women of the graduating class threw their caps into the air."

In this sentence, "threw" is the past tense of the verb "throw" and matches the subject "The men and women of the graduating class" in terms of verb agreement. It indicates that the action of throwing the caps into the air was performed by the graduating class.

The other options do not fit the context:

A. "Thorough" is an adjective that means complete or careful. It does not fit the action of throwing caps.

C. "Throwing" is a present participle form of the verb "throw" and does not match the tense needed in the sentence.

D. "Through" is a preposition that indicates movement or passage, but it does not fit the action of throwing caps.

Therefore, the correct word to make the sentence grammatically correct is B. "Threw."
