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

Option B is the correct sentence, which reads "The building's height was exceeded by its width." This sentence employs standard English spelling, where "exceeded" is spelled correctly, and the apostrophe in "it's" is incorrect, as it should be "its" without an apostrophe.

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."

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 final step of the writing process is editing, where the writer reviews and revises their work for clarity, coherence, and correctness.

Option C is most likely to be found in an email from a professor to her biology students at a college because it contains specific information related to the class schedule and activities. It mentions the research groups from a specific class meeting time, and gives a location where they should meet, which suggests it is a message intended for students in that class. Options A, B, and D are more likely to be found in casual conversations or in other types of messages not directly related to the biology class.

The Krebs cycle, part of cellular respiration, happens in the mitochondria. Fermentation and glycolysis happen in the cytoplasm, and photosynthesis occurs in plant cells' chloroplasts.

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

An interjection is a word or phrase that expresses a sudden or strong emotion or feeling. In this case, "ouch" is used to express pain or discomfort, which is a sudden sensation, and is not grammatically connected to the rest of the sentence. Therefore, "ouch" is an interjection.

This is because generating ideas is often the first step in the writing process, whether it's brainstorming, outlining, or freewriting. Before any other actions can take place, the writer needs to have a clear sense of what they want to communicate and how they want to structure their writing.

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.
