The following text is about conservation efforts.
The California condor came perilously close to extinction in the 1980s, when only 22 birds remained in the wild. Conservationists made the controversial decision to capture all remaining wild condors for a captive breeding program. Today, there are over 500 condors, with more than half living in the wild. While the population remains fragile and dependent on ongoing conservation efforts, the program is considered one of the most successful wildlife recoveries in history.
Which choice best states the main idea of the text?
Captive breeding programs always succeed in saving species
The California condor recovery program achieved remarkable success despite challenges
Wild condors are no longer at risk of extinction
Scientists first discovered condors in California in the 1980s
Correct Answer: B
Choice B is the correct answer. The text describes the recovery from 22 birds to over 500 but notes ongoing challenges ("fragile and dependent on ongoing conservation efforts").
- Evidence: Growth from 22 to 500+, called "one of the most successful wildlife recoveries."
- Reasoning: Success is clear but qualified by ongoing fragility.
- Conclusion: Remarkable success despite remaining challenges.
Choice A is incorrect because the text only discusses one program, not all programs. Choice C is incorrect because the population "remains fragile." Choice D is incorrect because discovery is not mentioned; the 1980s refer to near-extinction.
