The following text is about conservation.
National parks were created to preserve natural wonders for future generations, but they face a challenge: too much love. Popular parks like Yellowstone and Yosemite now receive millions of visitors annually, straining infrastructure and impacting wildlife. Park managers are experimenting with reservation systems, timed entry, and shuttle services to manage crowds while keeping parks accessible. The goal is to balance preservation with the democratic ideal that these public lands belong to everyone.
What is the main idea of the text?
National parks should be closed to all visitors
Parks face the challenge of balancing popularity with preservation
Wildlife has completely disappeared from major parks
Reservation systems have solved all park problems
Correct Answer: B
Choice B is the correct answer. The text describes the tension between preservation (the original goal) and high visitor numbers, noting managers' attempts to "balance preservation with... accessibility."
- Evidence: "Too much love," millions of visitors, experiments to manage crowds.
- Reasoning: The challenge is managing both goals.
- Conclusion: Balancing popularity and preservation is the core issue.
Choice A is incorrect because managers want to "keep parks accessible." Choice C is incorrect because the text says wildlife is "impacted," not gone. Choice D is incorrect because these are experiments, not proven solutions.
