OG11th-6

[bobo123456]

Not all life depends on energy from sunlight. Microbail 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 ther 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?

(C)a thorough survey of planet's surface is insuffcient to establish
beyond a doubt that the planet contains no life.
(E)finding bacteria remains in coal and oil would establish that
bacteria had been feeding on sbustances that had not been
produced from the energy of sunlight.

請問一下(C)要怎麼翻譯押?為什麼對呢?(E)錯哪裡呢?

(C) 對此星球表面做一徹底調查是不足以說明這個星球是沒有任何生物的 ---> 因為題目提到的例子, 生物都是在很深的地層(非表面)被找到, 所以帶出結論 : 如果表面沒有發現到任何生物, 是不足以說明這個星球是沒有生物的.

(E)finding bacteria remains in coal and oil would establish that 是假設情況, 並不代表真的就是這樣, 而且 had been feeding on 表過去曾經持續進行但現在停止的動作, 所以這些 bacteria 現在還是 feeding on sbustances produced from the energy of sunlight. 是weaken argument
