Which of the following sentences requires a citation?

This sentence presents a specific statistic that may not be common knowledge and is not the author's original idea, so it requires a citation to give credit to the source of this information. A citation is needed to show where this statistic came from, who conducted the study, and when it was conducted. Therefore, option C is the correct answer.

This is because generating ideas is often the first step in the writing process, whether it's brainstorming, outlining, or freewriting. Before any other actions can take place, the writer needs to have a clear sense of what they want to communicate and how they want to structure their writing.

The suffix "-ful" means "characterized by," so "graceful" means "characterized by grace."

A dangling modifier is a phrase or clause that does not logically modify any word in the sentence. Example: "My brother had an old truck that sat by the garage that needed paint." The phrase "that needed paint" is a dangling modifier because it does not clearly modify any word in the sentence.

It is unclear whether it is the truck or the garage needed paint.

The ureter is a large tube that carries urine from the kidneys to the bladder. The other options are small (microscopic) parts of the kidney that help filter blood.

An interjection is a word or phrase that expresses a sudden or strong emotion or feeling. In this case, "ouch" is used to express pain or discomfort, which is a sudden sensation, and is not grammatically connected to the rest of the sentence. Therefore, "ouch" is an interjection.

The passage is written in a narrative style with a mix of description and events. It mentions a specific character (Lydia) and introduces a setting and an upcoming event (Halloween costume contest). This style and content suggest that it is likely a short story.

The sentence "He liked to cook at home, but she preferred to eat at restaurants." correctly uses a compound sentence structure. It consists of two independent clauses "He liked to cook at home" and "she preferred to eat at restaurants" joined by the coordinating conjunction "but".

These prefixes mean "not" or "opposite of." "Mis-" means "wrongly" (like in "misunderstand"), so it does not fit.

"Ran" is the correct past tense of "run." The word "runned" is incorrect, "running" is the present participle, and "rant" is a different word.
