请教NN,OG11th黄-第6题

6.Not all life depends on energy from sunlight.Microbial 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 from the interior of the Earth

B.Bacteria are able to exist at the molten center of the Earth

C.A through survey of a planet's surface is insufficent to establish beyond a doubt that the planet contains no life.

D.Life probably exsits 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 bacteria had been feeding on substances that had not been produced from the energy of sunlight.

请教NN,此题是否为结论归纳题? 原文推理如下,结论:不是所有的生命依靠阳光产生能量。举例1.微生物生活在地下层5千米以下,举例2.细菌在海洋底靠氢气等生存。

既然题目中有了结论,问题还要问,如上陈述支持下面哪一个结论?

通过排除法可以得到C正确选项。但是,我对C选项很疑惑。beyond a doubt?什么意思

请教NN指点!

谢谢!

this question is Main conclusion type in laywer_1's methodology.in this type, the statement in right choice not only must be true but aslo is the generalization of main purpose of the author which may present the values of all evidence. Note that, the first sentence is just a sub-conclusion that will lead to further conclusion.

beyond doubt means "in a manner or to a degree that could not be doubted"

the argument ilustrates two kinds of life-form that can live deeply below the surface of the earth without depending on energy of sunshine, that is to say, any evidence showing that no life-form live on the surface of one planet is insifficent to establish a general conclusion that no life exist on the planet since there may be lifes living below surface.
