Which of the following sentences is punctuated correctly?

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

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 sentence that demonstrates proper subject-verb agreement is D. "Physics is a difficult subject to learn." In this sentence, the singular subject "Physics" agrees with the singular verb "is."

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.

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.

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.

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.

A complex-compound sentence has at least two independent clauses and one dependent clause. This sentence correctly combines all three parts.

The given sentences present a logical sequence of events, starting with the dog and owner being asleep in their home, followed bythe intruder breaking into the house, the dog biting the intruder who was attacking the owner, and finally, the statement about the dog being a man's best friend.

This order creates a clear and coherent story.

A dangling modifier is a phrase or clause that does not logically modify any word in the sentence. Example: "My brother had an old truck that sat by the garage that needed paint." The phrase "that needed paint" is a dangling modifier because it does not clearly modify any word in the sentence.

It is unclear whether it is the truck or the garage needed paint.
