Which of the following sentences demonstrates correct grammar and usage?

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."

These prefixes mean "not" or "opposite of." "Mis-" means "wrongly" (like in "misunderstand"), so it does not fit.

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

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.

This sentence is spelled correctly. The other choices have mistakes: "hear" instead of "here," "price" instead of "prize," and "harestyles" instead of "hairstyles."

1, 3, 4, 2, 5.

This order beginspresents the initial experiments, thenthe discovery, after which it discusses the research project,introduces the beliefand ends with the classification. While it provides the context for the belief, it starts with the discovery, which may confuse the reader as it doesn't establish the topic first.

The paragraph is as follows:

"Initially, we constructed experiments that explored new relationships among six major systems of the human body: circulatory, digestive, muscular, nervous, reproductive, and respiratory. Then, we discovered, through a series of curious events and calculations, that these systems were all intricately involved in a kind of psychic economy. Our experimental research project has focused on what we call the Psycho-Physical Performance Scale. We believe that this work will revolutionize our understanding of human behavior. Therefore, we ultimately chose to classify different triggers of human actions and productions according to these new relationships."

In the given sentence, "the class" is a singular noun and requires a singular possessive pronoun. "Its" is the correct form of the possessive pronoun "it" to use with a singular noun, as opposed to "it's," which is a contraction of "it is" and would not be appropriate in this context. "They're" is a contraction of "they are" and would not be appropriate because "class" is singular, not plural.

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.

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 sentence presents a specific statistic that may not be common knowledge and is not the author's original idea, so it requires a citation to give credit to the source of this information. A citation is needed to show where this statistic came from, who conducted the study, and when it was conducted. Therefore, option C is the correct answer.
