Which of the following sentences demonstrates correct grammar and usage?

Choice B: "Whenever the boys played in the rain, they came home with muddy clothes."

This is a complex sentence. "Whenever the boys played in the rain" is a dependent clause because it cannot stand alone as a complete thought, and "they came home with muddy clothes" is an independent clause because it can stand alone. The sentence does not contain two independent clauses joined by a coordinating conjunction (which would make it a compound sentence).

Choice D: "She wanted to go to the beach after she left work."

This is also a complex sentence. "She wanted to go to the beach" is an independent clause, and "after she left work" is a dependent clause because it cannot stand alone as a complete sentence.

To clarify:

• Complex sentence: Contains an independent clause and at least one dependent clause.
• Compound sentence: Contains two independent clauses joined by a coordinating conjunction (like "and," "but," or "or").

Thus, both B and D are complex sentences, but B is the most accurate answer in many tests as it clearly demonstrates the use of a dependent clause ("Whenever the boys played in the rain") followed by an independent clause.

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

"Ran" is the correct past tense of "run." The word "runned" is incorrect, "running" is the present participle, and "rant" is a different word.

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.

The correct use of "fewer" and "less" is important in proper grammar and usage. "Fewer" is used when referring to items that can be counted, while "less" is used for quantities that cannot be counted. In this case, "people" is a countable noun, so "fewer" is the correct word to use. Additionally, "effect" is the correct noun to use in this sentence, as it refers to the result or consequence of the action, while "affect" is a verb meaning to influence or have an impact on.

"The book" is the subject, and "is" correctly agrees with it. The other sentences have incorrect verb forms for their subjects.

This sentence correctly uses a comma before "so" to connect two ideas. The other sentences have missing or incorrect punctuation.

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.

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."
