Answer :
Final answer:
The provided student sentence is correct as is; punctuation such as commas and quotation marks is already properly used. For the reference sentences, punctuation needs correcting by either replacing a semicolon with a comma for clarity or combining sentence fragments to create a complete sentence.
Explanation:
To ensure the sentence is correct, we must add or remove punctuation as necessary. Regarding the sentence provided by the student (Reverse-Flash informed his students, "Never practice the trapeze without a net."), the punctuation is already correctly used. The sentence correctly uses a comma to indicate the speaker and the quotation marks to denote the spoken words.
However, when addressing the reference sentences provided for practice:
The rabbit darted out of the shadows. A flash of movement. The dog lunged and strained at the leash. These are sentence fragments that can be combined to form a complete thought: The rabbit darted out of the shadows, a flash of movement, and the dog lunged and strained at the leash.
Quentin’s father gave him a golden pocket watch; which was a priceless family heirloom. This sentence has a semicolon where a comma should be used: Quentin's father gave him a golden pocket watch, which was a priceless family heirloom.
