Correct Answer: C

Rationale: The correct answer is 'C: Quickly.' Adverbs modify verbs, adjectives, or other adverbs. In this sentence, 'quickly' describes how she finished her homework. Choice A 'She' is a pronoun, choice B 'Finished' is the verb, and choice D 'Homework' is a noun, making them incorrect choices for adverbs.

Correct Answer: A

Rationale: Choice A is the correct answer as it directly addresses the writing prompt by focusing on a specific threat faced by a national park in the United States, which is the rising sea level affecting Florida's Everglades National Park. This choice provides a clear thesis statement for a research report on the topic. Choices B, C, and D are incorrect. Choice B provides general information about the Grand Canyon but does not discuss any threats it is facing. Choice C is not relevant to the prompt as it talks about accidents on a specific highway within Glacier National Park rather than broader threats to the park itself. Choice D is about a personal experience at Acadia National Park and does not address any threats the park may be experiencing.

Correct Answer: D

Rationale: The correct answer is 'Not enough.' The prefix 'hypo-' means 'under' or 'not enough,' as seen in the word 'hypokalemia,' which refers to low levels of potassium. 'Better' (choice A), 'Above' (choice B), and 'Too much' (choice C) are all incorrect because they do not convey the meaning of insufficient or low levels associated with hypokalemia.

Correct Answer: C

Rationale: Choice C is the correct answer because it properly uses quotation marks to indicate a direct quote within the sentence ('My history presentation was great!'). Choices A, B, and D contain direct quotes but fail to use quotation marks, making them incorrect. In choice A, the direct question 'How was your day?' should be enclosed in quotation marks. In choice B, the direct quote 'It was awesome.' should also be enclosed in quotation marks. In choice D, the direct statement 'That's wonderful!' should be enclosed in quotation marks.

Correct Answer: B

Rationale: A complex sentence consists of one independent clause and at least one dependent clause. In sentence B, 'Because my tea was cold' is the dependent clause, indicating that it cannot stand alone as a complete sentence. Choices A, C, and D do not contain a dependent clause along with an independent clause, making them incorrect. Choice A is a compound sentence with two independent clauses joined by a coordinating conjunction. Choice C is a compound sentence with a series of independent clauses, but lacks a dependent clause. Choice D is a compound-complex sentence with two independent clauses and a dependent clause.
