第一段提到：海底幾乎沒燈光，而且壓力又比地球表面大好幾百倍。深海底部對人類而言是個非常不友善的環境，某些方面就如同外太空一樣，是個險惡又遙遠的空間。

Totally without light and subjected to intense pressures hundreds of times greater than at the Earth's surface, the deep-ocean bottom is a hostile environment to humans, in some ways as forbidding and remote as the void of outer space.


題目問作者為什麼要提到「外太空」，故應選擇

(B) it is similar to the ocean floor in being alien to the human environment

◥　因為海底像外太空一樣，對人類而言是個陌生的環境
