Which of the following sentences correctly follows the rules of grammar?

The word "their's" is incorrect. The correct form is "theirs" (without the apostrophe). "Theirs" already shows possession and does not need an apostrophe. Using an apostrophe here is a common mistake.

Anytime a student uses someone else's research or ideas, even in a summary, they must give credit with a citation. This shows honesty and avoids plagiarism. Personal thoughts and opinions do not need citations.

The correct word is "site", which means a location on the internet, like a website. "Sight" means vision, "cite" means to reference something, and "cight" is not a real word. In this sentence, "site" fits best because it's about creating a web presence.

A is correct because it uses formal words like "verify eligibility," "prior to enrollment," and "has been created." The tone is professional and clear. The other choices are too casual and use informal language like "pumped" or "stuff."

B is correct because it gives a practical announcement for students at college. A newsletter often includes updates like construction news. The other choices are more scientific, administrative, or general.

A uses a semicolon and transition word correctly to join two independent ideas. It shows contrast clearly and follows proper grammar. The other choices are confusing or contain grammar mistakes.

Explanation: Option B uses formal language with subject-specific vocabulary like "encompasses" and "categories," and a formal transition word, "however." This tone is suitable for academic and professional writing. The other choices include informal words or errors such as "a bunch of," "econ teacher," and unclear wording like “taste a deef,” making them inappropriate for formal writing.

D is correct because it includes a comma after the introductory clause "While some people love cats". This is the correct way to join two related ideas in one sentence. The other sentences contain spelling and punctuation errors.

D is correct because it uses the right spelling of "council" (a group), "affect" (to change), and "their" (possessive). The other choices confuse similar-sounding words that have different meanings.

The original phrase “Because of this” does not make sense, since the rediscovery of the genre was not a direct result of its disappearance. It is more of a surprising or reflective point.

C. "Nonetheless" works because it shows contrast. Even though baroque pop faded away quickly, people still rediscovered it later, so it helps the ideas connect.

The other options do not fit:

A. "In conclusion" is used to wrap up a full argument, not to transition between ideas.

B. "In spite of this" suggests something happened despite a problem, which does not match the meaning here.

D. "Altogether" means to sum up, which does not logically lead into the final idea.
