问题    The Internet has made some men so rich and ambitious that Earth no longer seems large enough to contain their fortunes or egos. That is the simplest explanation for the revival of interest in space exploration. But exploring space has always been a noble and inspiring pursuit undertaken for motives that were neither. The first space race, which resulted in the moon landings, was also a struggle for military edge. This was not just a matter of missile technology. There are at least 350 military satellites orbiting the world today. The widely-used GPS system was developed for military purposes. If the moon has been largely abandoned, this is because it has no economic or military use.
   The second space race sounds more justified. Mr. Musk, for example, promotes his SpaceX enterprise as something that saves humanity from potential extinction if we stay on one planet. It is possible that a nuclear war could destroy all human civilization or all human life on Earth. But a colony on Mars could hardly survive without constant contact and reinforcement from Earth, and it will still be full of human beings as short-sighted and quarrelsome as those who destroyed their original home. The universe is expanding very fast but it will never get fast enough that we could leave all our imperfections behind.
   There is an economic rationale to these private space programs: SpaceX is now a profitable company and private enterprises can accomplish things that governments no longer can. The effectiveness of this argument is little diminished by the fact that it is not true: the private competition builds on and relies on the publicly funded work. But it is quite clear that what drives the second space race is not really economics; there are much more effective ways to make money The real reason is the powerful human desire for exploration and adventure beyond what anyone else has achieved in those fields.
   We go into space to advance the frontiers of science and to provide a new perspective on humanity’s place in the universe. In doing so, we fuel scientific curiosity and inspire generations. Billionaires may be leading that charge, but Pluto is not just for the plutocrats. A better solution may be a collective one: The UN "Office for Outer Space Affairs" is offering space trips for nations that can’t afford them. The heavens are not just left to rich men.
In Paragraph Two, the author argues that the space race______.
选项 A、can possibly save humans from extinction
B、will ensure residents on Mars survive on their own
C、will help humans get rid of their imperfections
D、can hardly help human survival on Earth
答案D
解析 文章第二段第四句的大意是：没有来自地球的援助，到火星生活的人几乎无法生存。而且这些人目光短浅、喜欢争吵，与毁灭他们家园的人没什么区别。其含义是人类很难在其他星球上生活。
