Which of the following sentences demonstrates proper subject-verb agreement?

The prefix "inter-" implies the idea of between or among, often indicating a relationship or interaction between two or more things.

This sentence is complete because it contains a subject ("Matt") and a predicate ("spent most of the summer training for the marathon"), forming a complete thought. The other options are fragments that lack essential sentence elements. Option A is a fragment due to the missing main verb. Option C lacks a conclusion after the dependent clause. Option D has no main clause to form a grammatically correct sentence.

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

The adverb "swiftly" describes how the woman ran, indicating the manner or speed of the action.

The formal tone and legal language in the passage, including references to "appropriate remedy," "neglected to protect his interests," and "verdict presently sought," indicate that this text is likely from an appellate court opinion. Such opinions provide legal reasoning and interpretations used as precedents in future cases. The structured legal vocabulary distinguishes it from other publication types like business journals or newspaper articles.

This sentence uses correct capitalization by capitalizing the first letter of "The Red Cross" as a proper noun, and the first letter of the sentence. Additionally, it follows proper capitalization rules for the names of organizations and titles.

The prefix "mis-" means "incorrectly" or "badly." "Misalign" refers to aligning something incorrectly. Prefixes change the meaning of root words. For example, if car wheels are "misaligned," they are improperly positioned, potentially affecting driving performance. The other options contain prefixes with different meanings, such as "ir-" for "not" and "down-" indicating a reduction.

Receive is the only correctly spelled word.

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.

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.
