问题 According to the passage, what might be human being’s best choice for the final exit?
What does the author think interstellar travel can do?

选项 A、It practically enables human to escape the end of the world.
B、It simply postpones the process of human extinction.
C、It helps human avoid the fate of being vaporized or frozen.
D、It is a way to help human escape from death by gravity.

答案B

解析第2段第2句中的do no more than defer...表明星际旅行唯一的意义在于它可以推迟世界末日的到来，这与该段首句中的prolong the process意思相近，而the process指的就是首段讨论到的人类灭亡的过程，由此可见，选项B为本题答案。第2段只表明星际旅行可以推迟(defer)世界末日的到来，但世界末日仍然无法避免，因此选项A不正确；第2段倒数第2句表明星际旅行的结果是从一个星球到另一个星球最终也难逃vaporized和frozen的命运，因此选项C不对；而第2段末句表明最终我们仍然难逃gravity or entropy的死亡，因此选项D也不正确。
