Correct Answer: A

Rationale: Choice A is the correct answer. The word 'relevant' is spelled correctly in this sentence, and the sentence is well-constructed. In Choices B, C, and D, the word 'relevant' is misspelled as 'revelant,' 'relevent,' and 'relavance' respectively. These incorrect spellings make Choices B, C, and D grammatically incorrect, thereby making Choice A the only correct option.

Correct Answer: B

Rationale: The correct answer is B, 'On the 5:30 train.' This is a sentence fragment because it does not contain a subject and a verb. In this case, 'On the 5:30 train' is a prepositional phrase, not a complete sentence. Choices A, C, and D are complete sentences as they have both a subject and a verb, making them grammatically correct and not sentence fragments.

Correct Answer: C

Rationale: The correct answer is a colon (C). In this sentence, the colon is used to introduce a list of items that the speaker wants you to bring. The colon is the most suitable punctuation mark in this context. Choice A (;) is incorrect because a semicolon is used to connect independent clauses or items in a list when those items contain commas. Choice B (.) is incorrect because a period ends a sentence and does not fit here as the sentence continues. Choice D (,) is incorrect because a comma is used to separate items in a list, but the sentence needs a punctuation mark that introduces the list.

Correct Answer: A

Rationale: The correct answer is to 'Revise the content.' This step occurs last in the writing process as it involves reviewing the entire work to ensure clarity, coherence, and error-free writing. Choice B, 'Plan and conduct research,' typically takes place at the beginning of the writing process to gather information. Choice C, 'Select the topic and write the thesis statement,' is an early step to define the focus of the writing. Choice D, 'Organize the material into a logical format,' usually occurs after researching and outlining the content but before the final revision stage.

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.
