Write a research report about a national park in the United States that is experiencing threats.
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.
