Choice A is incorrect because the passage does not mention medical research as the focus of the Manhattan Project. Choice C is incorrect because the passage states that the project was initiated by the United States with support from the United Kingdom and Canada, not solely by the United Kingdom. Choice D is incorrect because the passage emphasizes the significant impact of the Manhattan Project on the course of history.

Choice B is the best answer because it accurately describes the main achievement of the Voyager spacecraft: providing detailed information about the outer planets and continuing to explore beyond the heliosphere. Choice A is incorrect because the passage states that the Voyager spacecraft were designed to study the outer planets, not the inner planets. Choice C is incorrect because the passage indicates that the spacecraft continue to send information back to Earth decades after their launch. Choice D is incorrect because the passage focuses on the spacecraft's study of the outer planets and their exploration beyond the heliosphere, not on studying Earth's atmosphere.

Choice C is the best answer because it accurately reflects the main idea of the text: that James Watt's steam engine revolutionized transportation and industry, contributing significantly to the Industrial Revolution. Choice A is incorrect because the passage focuses on the impact of the steam engine on transportation and industry, not agriculture. Choice B is incorrect because the passage states that the steam engine was developed in the late 18th century, not the 17th century, and it had a significant effect on transportation. Choice D is incorrect because the passage emphasizes the steam engine's significant role in transforming economies and societies.

Choice B is the best answer because it accurately describes the main contribution of Watson and Crick's discovery: providing a model for the double helix structure of DNA, which advanced the field of molecular biology. Choice A is incorrect because the passage does not mention the immediate eradication of genetic diseases as a result of their discovery. Choice C is incorrect because the passage states that their model provided insights into how genetic information is stored and transmitted, not that proteins are the carriers of genetic information. Choice D is incorrect because the passage highlights the significant impact of their discovery on medicine, agriculture, and other fields.

Choice C is the best answer because it accurately describes the main impact of the printing press as increasing the availability of written material and spreading knowledge. Choice A is incorrect because the passage states that the printing press increased the availability of books, not made them more expensive and less accessible. Choice B is incorrect because the passage highlights the crucial role of the printing press in significant historical movements, not a minor one. Choice D is incorrect because the passage states that the printing press was invented in the 15th century and had a significant impact.

Choice C is the best answer because it accurately reflects the main idea of the text: that Alfred Wegener's theory of continental drift was initially dismissed but later gained support through the development of the theory of plate tectonics. Choice A is incorrect because the passage states that Wegener's hypothesis was initially dismissed, not immediately accepted. Choice B is incorrect because the passage explains that the discovery of mid-ocean ridges supported, not disproved, Wegener's theory. Choice D is incorrect because the passage indicates that the scientific community initially rejected the idea of moving continents.

Choice C is the best answer. The passage discusses how Einstein's 1905 papers, especially on special relativity, transformed physics and introduced new concepts. Choice A is incorrect because it does not capture the broader impact of all his 1905 papers. Choice B is incorrect because it overstates the theory's impact by saying it replaced Newton's laws, rather than challenging and expanding them. Choice D is incorrect because it misrepresents the significance of his contributions by implying limited practical application, which is not discussed.

Choice B is the best answer. The passage emphasizes Yellowstone's role as a pioneering effort in global conservation. Choice A is incorrect because it lacks the emphasis on the global precedent set by the park. Choice C is incorrect because tourism is not mentioned as the primary goal. Choice D is incorrect because the passage does not discuss the decline of natural resource exploitation.

Choice B is the best answer. The passage highlights how the printing press helped increase literacy and spread knowledge, leading to significant cultural and intellectual movements. Choice A is incorrect because it focuses too narrowly on the cost of books. Choice C is incorrect because it overstates the role of the printing press in causing the Renaissance. Choice D is incorrect because the passage discusses broader impacts, not just in art.

Choice C is the best answer. The passage underscores how Watson and Crick's discovery of the DNA structure profoundly altered genetic science. Choice A is incorrect because it overlooks the contributions of Franklin and Wilkins. Choice B is incorrect because the passage does not specifically discuss genetic mutation. Choice D is incorrect because, while acknowledging Franklin's significant contributions, the passage emphasizes the overall impact of Watson and Crick's discovery.
