Choice A is the correct answer. The passage specifically mentions that regular physical activity is linked to lower levels of depression, anxiety, and stress, directly supporting the positive impact on mental health. Choice B, while correct, is more specific and doesn't fully capture the overarching evidence. Choice C mentions a mechanism but does not directly state the mental health impact. Choice D, although generally correct, does not provide as direct evidence of the impact as Choice A.

Choice D is the correct answer. The passage discusses both economic and environmental benefits of high-speed rail systems, making it the best summary. Option A is incorrect as it only mentions the speed of the trains. Options B and C are partially correct but do not encompass the full range of benefits discussed in the passage.

Choice B is the correct answer. The passage indicates that urban farming provides local food sources and enhances biodiversity, both mentioned as benefits of urban farming. Choice A is incorrect as it only lists different types of urban farming without highlighting the benefits. Choice C, while providing an example of crop production, does not cover the broader benefits. Choice D comments on the trend of increasing urban farming but does not describe the benefits.

Choice D is the correct answer. The passage mentions the critical role pollinators play in the reproduction of crops humans rely on for food, supporting the need for efforts to mitigate threats. Choice A, while describing the importance of pollinators, does not directly support the need for mitigation efforts. Choice B lists reasons for the decline but doesn't connect to why mitigation is necessary. Choice C discusses efforts but doesn't provide the underlying reason why these efforts are important.

Choice B is the correct answer. The passage emphasizes the extensive lengths of the aqueducts and the sophisticated engineering involved, supporting the assertion that they were engineering marvels. Choice A is incorrect because it only mentions the purpose of transporting water without highlighting the engineering aspects. Choice C is incorrect as it focuses on the construction timeline rather than the engineering ingenuity. Choice D, while describing the uses of the water, does not highlight why the aqueducts are considered marvels of engineering.

Choice C is the correct answer. The passage discusses the threats monarch butterflies face, including habitat loss and climate change, supporting the need for habitat preservation. Choice A is incorrect because it only mentions the migration distance without addressing the threats. Choice B, while providing information on navigation, does not support the need for preservation. Choice D, though discussing preservation efforts, does not explicitly describe the data supporting the necessity for habitat preservation.

Choice C is the best answer because it directly supports the idea that advancements in wind power technology have improved its efficiency. The passage discusses how modern wind turbines are more efficient, and finding that they can generate electricity at lower wind speeds than earlier models aligns with this concept. Choice A is incorrect because it addresses maintenance rather than efficiency. Choice B is incorrect because it focuses on the geographical range rather than efficiency. Choice D is incorrect because it pertains to public support rather than technological efficiency.

Choice B is the best answer because it directly supports the idea that gene therapy can provide long-lasting solutions for genetic disorders. The passage discusses the potential for gene therapy to target the root cause of genetic disorders and offer long-term solutions, and finding that patients treated with gene therapy for SCID show no symptoms years after treatment aligns with this concept. Choice A is incorrect because it addresses cancer treatment rather than long-lasting solutions for genetic disorders. Choice C is incorrect because it focuses on the precision of gene editing techniques rather than the long-term effectiveness of gene therapy. Choice D is incorrect because it pertains to public opinion rather than the efficacy of gene therapy.

Choice B is the best answer because it directly supports the idea that advancements in robotics have improved the functionality of prosthetic limbs. The passage discusses how modern prosthetic limbs allow for greater precision and mimic natural movements, and finding that patients using these advanced prosthetics report improved ability to perform daily tasks aligns with this concept. Choice A is incorrect because it focuses on materials rather than functionality. Choice C is incorrect because it addresses surgical techniques rather than the functionality of prosthetic limbs. Choice D is incorrect because it pertains to public awareness rather than the actual improvements in prosthetic functionality.

Choice B is the best answer because it directly supports the idea that biodiversity enhances ecosystem resilience. The passage discusses how diverse ecosystems are better equipped to withstand disturbances, and finding that monoculture farms (with low biodiversity) are more susceptible to pest infestations than polyculture farms (with high biodiversity) aligns with this concept. Choice A is incorrect because it focuses on the adaptability of individual species rather than ecosystem resilience. Choice C is incorrect because it deals with animal migration rather than biodiversity. Choice D is incorrect because it highlights the difference in species diversity between urban and rural areas without addressing ecosystem resilience.
