Which of the following punctuation marks is used incorrectly in the sentence? "Otto, somewhat abruptly, got up out of his chair, and just like that, headed into the next room."

Correct Answer: C

Rationale: The semicolon after "that" is used incorrectly; a comma should be used instead. Semicolons are typically used to join two independent clauses without a conjunction. In this sentence, the phrase "just like that" is not an independent clause, so a comma is more appropriate for separating it from the rest of the sentence. Choices A, B, and D all use commas correctly within the sentence.

Correct Answer: C

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: D

Rationale: Choice D is the correct answer as it uses quotation marks to properly set off the spoken words. In this sentence, the spoken words by Philip are enclosed within double quotation marks and correctly punctuated with a comma before the attribution 'said Philip.' Choices A, B, and C contain errors such as missing commas, incorrect placement of quotation marks, or incorrect punctuation within the quoted speech. For example, in Choice A, there should be a comma after 'appetite' within the quotation. In Choice B, the comma should be placed inside the quotation marks. Choice C incorrectly places the attribution 'said Philip' within the quotation of spoken words, which is not the standard practice.
