Correct Answer: D

Rationale: The correct answer is D. The passage's descriptive and narrative style, focusing on character and setting details, suggests that the writer is an author of literature. Choice A is incorrect because there is no indication of a business environment or professional context in the passage. Choice B is incorrect as the passage does not align with the technical or formal language typical of scientific journals. Choice C is incorrect as the passage does not reflect the style or content common in student papers, which are usually more structured and formal.

Correct Answer: B

Rationale: The correct answer is B: 'Check to see that the coffee maker in the breakroom is unplugged.' This task is explicitly mentioned in the memo as one of the tasks to be performed when leaving the office. Choices A, C, and D are not specific tasks listed in the memo and do not directly relate to the instructions provided. Therefore, they are incorrect choices. It is essential to pay attention to the specific details mentioned in the instructions to identify the correct task to perform.

Correct Answer: A

Rationale: Option A uses correct punctuation by correctly utilizing the semicolon to separate two closely related independent clauses. This punctuation choice effectively conveys the relationship between the two ideas presented in the sentence. Choice B is incorrect because it uses a comma without a coordinating conjunction to join two independent clauses. Choice C is incorrect as it lacks the coordinating conjunction 'and' after the comma to connect the two independent clauses. Choice D is incorrect because it lacks any punctuation or conjunction to properly separate the two independent clauses, leading to a run-on sentence.

Correct Answer: B

Rationale: The correct answer is B: 'Let's eat, Grandma!' The comma is correctly used to separate the direct address 'Grandma' from the rest of the sentence. In choice A, there should be a comma after 'eat' to separate the direct address. Choice C is missing an apostrophe in 'Lets,' and there should be a comma after 'eat' to separate the direct address. Choice D incorrectly places a comma after 'Lets,' and there should be a comma after 'eat' to separate the direct address.

Correct Answer: C

Rationale: The comma after 'glasses' is used incorrectly in the sentence. Commas are not needed to separate the subject from the verb in this context. In this case, the subject 'She' is not separated from the verb 'wore,' making the comma unnecessary. The semicolon after 'book' is appropriate for separating two independent clauses, the comma after 'long' is correctly used for introductory elements, and the period at the end of the sentence is necessary for indicating the end of a complete thought.
