It's really time for me to leave, and yet there are still so many things I'd like to do; next year I think I'll spend an extra week. Which of the following punctuation marks is used incorrectly in the sentence above?

Correct Answer: A

Rationale: The comma after 'think' is unnecessary and incorrect. It should be removed to correct the sentence. The semicolon after 'do' is correct as it separates two independent clauses. The period at the end of the sentence is necessary to indicate the end of the sentence. The comma after 'and yet' is correctly used to separate two independent clauses joined by a coordinating conjunction.

Correct Answer: A

Rationale: The correct answer is 'Peer-reviewed articles.' Peer-reviewed articles are considered highly reliable because they undergo a rigorous evaluation process by experts in the field before publication. This process ensures that the research presented is of high quality and meets academic standards. Choice B, 'Wikipedia,' is not considered a reliable source for scholarly research as it can be edited by anyone, leading to potential inaccuracies. Choice C, 'Opinion articles from a newspaper,' may provide perspectives but may not always be based on rigorous research or evidence. Choice D, 'Blogs and other social media,' lack the rigorous review process that peer-reviewed articles undergo, making them less reliable for scholarly research.

Correct Answer: A

Rationale: The correct answer is 'A: Likely.' An adverb is a word that modifies a verb, adjective, or another adverb. In this sentence, 'likely' is an adverb that modifies the verb 'annoyed,' expressing the probability or likelihood of the action. The other choices, 'B: Annoyed,' 'C: Assigned,' and 'D: Unnecessary,' are not adverbs. 'Annoyed' is a past tense verb, 'Assigned' is a past tense verb, and 'Unnecessary' is an adjective describing the type of busy work assigned. Therefore, 'A: Likely' is the only adverb in the sentence.

Correct Answer: A

Rationale: The main idea of the paragraph is to highlight the dangers associated with coal mining. The sentence 'Coal miners risk injury and health issues on a daily basis' supports the concept that coal mining is a dangerous job. Choice B is incorrect as it focuses on cleanliness rather than safety. Choice C is incorrect as the location of coal mining is not the primary focus of the paragraph. Choice D is incorrect as it does not encompass the full extent of risks mentioned in the paragraph.

Correct Answer: B

Rationale: The correct answer is B: Supporting details. Supporting details are specific information that backs up the main points in an essay, such as the who, what, where, when, and why in A.J.'s essay about the Civil War. In this case, A.J. included crucial facts and explanations to support his main arguments. Choice A, 'Emphasis paragraph,' does not directly relate to providing specific information like supporting details do. Choice C, 'Topic sentence,' introduces the main idea of a paragraph, not the specific supporting information. Choice D, 'Transitions,' are used to connect ideas and paragraphs smoothly, but they do not provide the specific information needed to support the main points in an essay.
