J Difficulty: High

Category: Inference

Getting to the Answer: The clue “The passage suggests” indicates that this is an Inference question, but the question stem does not point to any one paragraph definitively. When you receive limited help from the question stem, use your passage notes to help you confirm or rule out choices. Eliminate F because, according to paragraph 2, no organic compounds were found in Martian soil. Choice G is incorrect because the question asks for a difference between Earth and Mars. Both Earth and Mars lie in the path of ultraviolet radiation; the crucial distinction is that Earth is shielded by ozone. Choice H is also a distortion because the passage does not mention the amount of carbon dioxide in Earth’s atmosphere. In paragraph 4, the passage tells us that even if life had begun on Mars, it could not have survived. The correct answer, then, is (J).
