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 eh molten center of the Eargh.
C. A through survey of a planet's surface is insufficient to establish beyond a doubt that the planet contains no life.
D. Life probably exist 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 bacterial had been feeding on substances that had not been produced from the energy of sunlight.
Answer:C This statement properly uses the existence of the microbes far below the land's surface and of the bacterial far below the ocean's surface to draw a general conclusion about the potential existence of life below the surface of a planet.
A,B,E. The conclusion must include both microbes and bacteria.
D. The passage provides no evidence about comets to lead to this conclusion.
这道题的问题是The statements above, if true, best support which of the following as a conclusion?
我看费费笔记上说support既可以表示加强也可以表示归纳。
如果提问形式是which of the following will be supported by the argument above?是归纳题
而如果提问形式是which of the following if true will support the argument above?就是加强题了
请教各位牛牛，这题应该是分为哪一类呢？ |
