Correct Answer: A

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

Correct Answer: A

Rationale: The correct answer is A. In sentence A, the modifier 'Running through the park' is misplaced because it makes it seem like the dog was the one running through the park rather than the intended meaning that the speaker was running through the park. In choices B, C, and D, the modifiers are correctly placed, providing clear and concise descriptions without causing confusion about who or what is performing the action.

Correct Answer: A

Rationale: The correct answer is A: 'After the game.' A prepositional phrase consists of a preposition and its object, describing a relationship in time, location, or direction. In this case, 'After' is the preposition, and 'the game' is its object, making it a prepositional phrase. Choices B, C, and D do not contain prepositional phrases. Choice B, 'Running fast,' is a gerund phrase with an adverb modifying a verb. Choice C, 'She sings,' is a subject-verb sentence construction. Choice D, 'Can you help me?' is an interrogative sentence asking for assistance.

Correct Answer: A

Rationale: The correct use of quotation marks involves enclosing the exact words of a speaker, with punctuation placed inside the quotes. Choice A is the correct answer as it correctly uses quotation marks to enclose the spoken words 'Did you finish your homework?' with the appropriate punctuation inside the quotes. Choices B, C, and D incorrectly position the quotation marks or omit necessary punctuation, making them grammatically incorrect. In choice B, the closing quotation mark is missing. In choice C, the punctuation is placed outside the closing quotation mark, and in choice D, the quotation mark is incorrectly placed after 'homework,' disrupting the flow of the quoted speech.

Correct Answer: B

Rationale: The correct answer is B because the peer review process demands time and attention for a thorough evaluation by experts. Choice A is incorrect because peer review does not guarantee acceptance of all papers; rather, it aims to assess the quality and validity of research. Choice C is incorrect as peer review is not always a simple or straightforward task due to the detailed scrutiny involved. Choice D is incorrect because peer review does not allow papers to be published instantly; instead, it involves a rigorous evaluation process before publication.
