Which of the following is a complex sentence?

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.

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.

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 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 sentence " There were buffalo in every western territory of the United States as of 1860." requires citation because it presents a claim or fact that is not common knowledge and needs to be supported by a source

A complex sentence is one that contains an independent clause and at least one dependent clause.

In Choice C: "Since time was running short, I hurriedly brushed my teeth while breakfast was warming up," we have an independent clause: "I hurriedly brushed my teeth," and a dependent clause: "Since time was running short." The dependent clause cannot stand alone as a complete sentence, so it depends on the independent clause for its meaning. This combination of an independent and dependent clause makes Choice C a complex sentence.

The other choices are not complex sentences because they either lack a dependent clause or do not have the same level of complexity in their structure.

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.

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

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.

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."
