Based on the language in the passage, which one of the following scenarios is correct?

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 best way for an author to cite sources when submitting a paper for publication in an academic journal is to research and follow the citation style specified by that particular journal. This ensures that the paper meets the submission standards and requirements of the journal. Option A is incorrect because it suggests trying out different citation styles, which may not align with the journal's requirements. Option C is incorrect because it emphasizes the author's preference over adherence to journal guidelines. Option D is incorrect as it assumes the author's personal style should be used regardless of journal requirements.

Correct Answer: D

Rationale: The correct answer is D, 'Exclamation mark.' Exclamation marks are used to express strong emotions such as excitement, surprise, or urgency. They indicate a heightened level of emotion in a sentence. Periods (A) are used to indicate the end of a statement, commas (B) are used to separate elements in a sentence, and question marks (C) are used to indicate questions or uncertainty. In this context, the use of an exclamation mark is the most appropriate choice to convey a strong feeling or emotion.

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: A

Rationale: The correct answer is B: 'John threw the ball.' Active voice sentences have the subject performing the action, which is the case in this sentence where 'John' is the subject performing the action 'threw.' Choices A, C, and D are in passive voice where the subject receives the action rather than performing it.
