Which of the following sentences requires a citation?

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.

The language convention violated in the sentence is pronoun-antecedent agreement. The pronoun "you" does not agree in number with its antecedent "a person." It should either be "he or she" or "they" to agree with the singular or plural antecedent.

Choice B: "Whenever the boys played in the rain, they came home with muddy clothes."

This is a complex sentence. "Whenever the boys played in the rain" is a dependent clause because it cannot stand alone as a complete thought, and "they came home with muddy clothes" is an independent clause because it can stand alone. The sentence does not contain two independent clauses joined by a coordinating conjunction (which would make it a compound sentence).

Choice D: "She wanted to go to the beach after she left work."

This is also a complex sentence. "She wanted to go to the beach" is an independent clause, and "after she left work" is a dependent clause because it cannot stand alone as a complete sentence.

To clarify:

• Complex sentence: Contains an independent clause and at least one dependent clause.
• Compound sentence: Contains two independent clauses joined by a coordinating conjunction (like "and," "but," or "or").

Thus, both B and D are complex sentences, but B is the most accurate answer in many tests as it clearly demonstrates the use of a dependent clause ("Whenever the boys played in the rain") followed by an independent clause.

The given sentences present a logical sequence of events, starting with the dog and owner being asleep in their home, followed bythe intruder breaking into the house, the dog biting the intruder who was attacking the owner, and finally, the statement about the dog being a man's best friend.

This order creates a clear and coherent story.

A compound sentence is a sentence that consists of two or more independent clauses joined by a conjunction. Example: "I like my job, but I like this more." This sentence has two independent clauses, "I like my job" and "I like this more," joined by the conjunction "but."

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.

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.

It follows all the rules of punctuation compared to the rest.

The sentence that demonstrates proper subject-verb agreement is D. "Physics is a difficult subject to learn." In this sentence, the singular subject "Physics" agrees with the singular verb "is."

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