Which of the following sentences correctly uses a compound sentence structure?

Option B is the correct sentence, which reads "The building's height was exceeded by its width." This sentence employs standard English spelling, where "exceeded" is spelled correctly, and the apostrophe in "it's" is incorrect, as it should be "its" without an apostrophe.

Option C is most likely to be found in an email from a professor to her biology students at a college because it contains specific information related to the class schedule and activities. It mentions the research groups from a specific class meeting time, and gives a location where they should meet, which suggests it is a message intended for students in that class. Options A, B, and D are more likely to be found in casual conversations or in other types of messages not directly related to the biology class.

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 sentence written correctly is: "The lizard has the ability to alter its coloration to blend in with the foliage." The word "alter" is spelled correctly, and the pronoun "its" is used correctly to show possession. The word "altar" in options B and D is a different word that means a raised platform used for religious or ceremonial purposes, and the word "it's" in option B is a contraction of "it is," which does not make sense in the context of the sentence.

The concluding sentence of a paragraph serves to sum up the main idea or point that has been discussed in the paragraph. It provides closure to the paragraph and helps transition to the next one. Therefore, the correct answer is B.

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

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

In the sentence, "The pumpkin crop was incredibly small this year because of excessive rain in the spring and he", the word "incredibly" is an adverb. Adverbs are words that modify verbs, adjectives, or other adverbs. In this case, "incredibly" modifies the adjective "small," indicating the degree or intensity of the smallness of the pumpkin crop.

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.

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.
