Read this paragraph and choose the best concluding sentence.

The Lower Salt River, an area in Arizona that's home to an abundance of wildlife, is at risk. To preserve this essential habitat and the wildlife that relies on this water source, residents must stop littering. Nesting bald eagles, herons, and egrets, as well as bobcats, coyotes, and wild horses, all rely on this water source. Human activity—tubing, fishing, and kayaking at the river—is inevitable, but dangerous and polluting litter is not.

In this sentence, the adverb "slowly" is used correctly to modify the verb "wrote," indicating the manner in which the student wrote. Additionally, the adjective "slow" is appropriately used to describe the writer in the second part of the sentence.

The prefix "re-" indicates repetition or duplication, often suggesting the idea of doing something again.

In this sentence, the preposition "at" is followed by its object, which is "the clown." The object of the preposition is the noun or pronoun that follows the preposition and relates to the rest of the sentence.

After gathering research and creating information cards, the next logical step is outlining the structure of the writing. Outlining helps organize ideas logically, ensuring a smooth flow of information in the draft. It provides a roadmap for drafting and helps writers prioritize content effectively. Editing and revision come after the initial draft is complete.

"The boy or the girls come to school late," the verb "come" correctly agrees with the plural subject "girls" since the presence of either the boy or the girls triggers a plural verb.

The best concluding sentence should reinforce the main idea of the paragraph while providing a strong closing statement. Option C effectively restates the call to action presented earlier in the paragraph, emphasizing the importance of preventing littering to protect wildlife. The other options either repeat existing information or do not effectively wrap up the paragraph.

This option correctly uses a comma after "dull" to separate the introductory clause from the main clause. Additionally, it correctly uses an apostrophe in "it's" to indicate the contraction of "it is."

This sentence uses commas correctly. The appositive phrase ("a first-generation German-American") is properly set off with commas to provide additional information about Dorothes Lange. Commas are also correctly used in the list of social issues: "poverty, racism, and migration." Proper comma usage improves clarity and readability.

Sentence A is punctuated correctly because it maintains proper dialogue formatting. The exclamation mark within the quotation marks correctly conveys the owner's emotion, and the comma before the dialogue tag ("Pat said") is appropriately placed. The closing punctuation is also correct.

A pronoun is a word that takes the place of a noun. In this sentence, "us" is a personal pronoun referring to the speaker and a group of people. It functions as the object of the preposition "for." Personal pronouns like "us" are commonly used to avoid repetition of nouns in sentences.
