Passage 2
If the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the planet. By the middle of the 21st century, if present trends continue, we will have used up all the oil that drives our cars, for example.

But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however, has recently been suggested by an American scientist, Professor Carl Sagan.
Sagan believes that before the earth's resources are completely exhausted it will be possible to change the atmosphere of Venus and so create a new world almost as large as earth itself. The difficulty is that Venus is much hotter than the earth and there is only a tiny amount of water there.
Sagan proposes that algae organisms, which can live in extremely hot or cold atmospheres and at the same time produce oxygen, should be bred in conditions similar to those on Venus. As soon as this has been done, the algae will be placed in small rockets. Spaceships will then fly to Venus and fire the rockets into the atmosphere.

参考解析
解析：由第一段可知，如果人口按照目前速度持续膨胀的话，地球上最终会缺乏资源来维持这么多的生命。即使科学家发明出替代资源，拥挤的人口也使我们不得不到其他星球寻找生存空间。但是目前太阳系还没有发现能维持生命的行星。因此和缺乏资源相比，缺乏生存空间才是最令人担忧、最难解决的问题。所以正确答案为C。
