Which of the following is a complex sentence?

The sentence written correctly is: "The lizard has the ability to alter its coloration to blend in with the foliage." The word "alter" is spelled correctly, and the pronoun "its" is used correctly to show possession. The word "altar" in options B and D is a different word that means a raised platform used for religious or ceremonial purposes, and the word "it's" in option B is a contraction of "it is," which does not make sense in the context of the sentence.

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.

A complex sentence is one that contains an independent clause and at least one dependent clause.

In Choice C: "Since time was running short, I hurriedly brushed my teeth while breakfast was warming up," we have an independent clause: "I hurriedly brushed my teeth," and a dependent clause: "Since time was running short." The dependent clause cannot stand alone as a complete sentence, so it depends on the independent clause for its meaning. This combination of an independent and dependent clause makes Choice C a complex sentence.

The other choices are not complex sentences because they either lack a dependent clause or do not have the same level of complexity in their structure.

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

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 passage is written in a narrative style with a mix of description and events. It mentions a specific character (Lydia) and introduces a setting and an upcoming event (Halloween costume contest). This style and content suggest that it is likely a short story.

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.

The suffix "-ful" means "characterized by," so "graceful" means "characterized by grace."

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.

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.
