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
(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!
我觉得6象要求通过给定的一些事实推理结论。事实是某些生物可以生活的星球的很底层，所以光扫描某个星球的表面是无法确认哪个星球上是否有生命的。
123 确实难啊。怎么用无关词啊？能用这几个选项为例讲解一下吗？非常谢谢！
仔细看题后发现有几个特别现象：80pages >>20 pages，但是20 pages are by three copyiest，暗示plague的作用导致 some significant disruption.所以只要仅发生一次的话，那这几个人就死于那个plague，而知道仅有的plague的时间是1148，那这个copy就是大约1148完成的，起码其中的20页中的前一部分（那三个copyists前两个的文字）就在1148年完成。
123.A.从第四个copyist中的handwriting中可以确定这篇copy的日期,如果人们能辨识出前三个copyist的handwriting,那么加强结论,但是事实他们对此一无所知.所以A排除
B.结论是这篇copy完成于1148年,意思是让你确定他完成的时间点,与瘟疫持续时间的长短无关
C.copyist在一天内的工作量与结论无关
E.不同类型的copyist的工作效率与结论无关
个人看法.另外,我还是不太明白楼上对于D的解释,可以再详细点吗?
对于第6题,我的结论是:不是所有的生命对依赖太阳能,似乎和楼上的相差很远啊,不知道为什么会这样?

第6题你主要看前面的两个例子都是在surface以下很深的地方有生物，那么仅仅靠表面有没有生物是不足以判断这整个星球有没有生物的。即不能从部分推知全部
看了一下答案，123 用取反的方法证明D可以起支持作用。Choice D is the best answer because if there had been other outbreaks of plague in the relevant period, one of these, instead of the plague of 1148, might have disrupted the manuscript’s production. This information therefore supports the hypothesis.
看了一下6的解释，讲的更清楚
Situation Microbes found five kilometers below the surface of the Earth and bacteria found on the deep ocean floor are both evidence that not all life depends on sunlight.
Reasoning What conclusion may be drawn from this statement? Since the passage includes information about both microbes below Earth's surface and bacteria on the ocean floor, the conclusion must embrace both situations. The conclusion will not be a specific statement about either one or the other, but rather a general statement about both. What is true equally of the microbes and bacteria discussed here? They are both life forms that exist far below the surface of the Earth.
