问题 What does the passage say about asteroids and meteoroids?
What do people think of the suggestion of using nuclear weapons to alter the course of asteroids?
选项 A、It sounds practical but it may not solve the problem.
B、It may create more problems than it might solve.
C、It is a waste of money because a collision of asteroids with Earth is very unlikely.
D、Further research should be done before it is proved applicable.
答案B
解析 参见最后一段“The cure…，The world has…”其中cure一词指的是阻止小行星撞击地球的解决办法，即用核武器改变小行星的运行轨道，而 disease一词指的是小行星可能撞击地球这一令世人担心的事，所以，可以推断出：核武器比小行星带来的后果，也许更糟……大批对付小行星的核武器带给世人的恐惧要大于那些毁灭性的石头，故选B。
