Which of the following is the final step of the writing process?

Option A is correctly punctuated. It uses the possessive form "student's" to indicate that the friend belongs to the working student.

The possessive apostrophe is placed after "student" and before the "s" to indicate that the friend is singular and not plural.

The word that defines "subterranean" based on the prefix "sub-" is B. Underground.

A topic sentence is the main idea or point of a paragraph. It serves as a guide to the reader, telling them what the paragraph is going to be about. A topic sentence should be clear, concise, and focused on a single idea, and it should summarize the main point of the paragraph. Therefore, the correct answer is A.

According to the rules of capitalization, the first letter of a sentence and proper nouns should be capitalized. In option D, "Rocky Mountains" is a proper noun and it is capitalized correctly. Geography is also a proper noun identifying a subject.

In option A, "College" should not be capitalized as it is a common noun.

In option B, it is partly correct however"Western" should be capitalized as it is a proper adjective referring to a specific region.

In option C, "A1 Plumbing Board of Directors" is capitalized correctly, but "range" should not be capitalized as it is a common noun.

Therefore, option D is the correct answer.

Choice A: In this option, the subject "The boys and girl" is a compound subject that includes both "boys" and "girl." The mistake here lies in the verb "is," which is singular. Since the subject is plural due to the presence of "boys," the correct verb should be "are."

Choice B: This choice correctly follows subject-verb agreement rules. The subject "The boy" is singular, so the verb "come" is appropriately singular. Similarly, for "the girls," which is plural, the verb "come" is used in its plural form.

Choice C: Here, the subject "The boys" and "the girls" are connected by "or," indicating a singular choice. However, the verb "sings" is in the singular form, which is incorrect for plural subjects. To maintain agreement, the correct verb should be "sing."

Choice D: In this option, the compound subject "The boys and girl" is again presented. However, the verb "visits" is singular, not in agreement with the plural subject. To ensure proper subject-verb agreement, the verb "visit" should be used.

Proofreading is the final step, where you check for spelling and grammar mistakes. The other steps happen earlier in the writing process.

The commas correctly set off "or jiaozi," which is an extra detail. The other sentences either need a comma for direct address, have comma splices, or have incorrect punctuation.

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.

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.

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