6. Not all life depends on energy from sunlight. Microbial life has been found in bedrock more than five kilometers below the surface of the Earth, and bacteria have been found on the deep ocean floor feeding on hydrogen and other gases rising from the interior of the Earth through vents in the ocean floor. The statements above, if true, best support which of the following as a conclusion? (A) The location in the bedrock where microbial life was found was not near a system of volcanic vents through which hydrogen and other gases rose from the interior of the Earth. (B) Bacteria are able to exist at the molten center of the Earth. (C) A thorough survey of a planet’s surface is insufficient to establish beyond a doubt that the planet contains no life. (D) Life probably exists on Sun-orbiting comets, which are cold agglomerations of space dust and frozen gases. (E) Finding bacterial remains in coal and oil would establish that the bacteria had been feeding on substances that had not been produced from the energy of sunlight. 请问下:这道题是加强题吗? 结论是:不是所有生命都依赖太阳能的.用two evidences(microbial life和bacteria) 来支持结论. 如何理解正确答案C,对于错误答案A,B,D,E. OG好像都用了一种解释,即conclusion要包括两个方面,即证据的两点,思路被搅浑了. 123. Codex Berinensis, a Florentine copy of an ancient Roman medical treatise, is undated but contains clues to when it was produced. Its first 80 pages are by a single copyist, but the remaining 20 pages are by three different copyists, which indicates some significant disruption. Since a letter in handwriting identified as that of the fourth copyist, mentions a plague that killed many people in Florence in 1148, Codex Berinensis was probably produced in that year. Which of the following, if true, most strongly supports the hypothesis that Codex Berinensis was produced in 1148? (A) Other than Codex Berinensis, there are no known samples of the handwriting of the first three copyists. (B) According to the account by the fourth copyist, the plague went on for 10 months. (C) A scribe would be able to copy a page of text the size and style of Codex Berinensis in a day. (D) There was only one outbreak of plague in Florence in the 1100’s. (E) The number of pages of Codex Berinensis produced by a single scribe becomes smaller with each successive change of copyist. 能用无关词排除法得答案,但是不知道为什么选D,有NN人可以把它解释得详细点吗? 以上两题恳请友人指点,谢谢!
