单选题 What do people think of the suggestion of using nuclear weapons to alter the course of asteroids?

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.

【正确答案】 B

【答案解析】[解析] 本题属细节性问题。文章的最后一段，是人们对这个问题的看法，因此读完这一段后，对比四个选项，看哪一个和文章的内容更加符合。首先，我们可以排除A选项It sounds practical but it may not solve the problem。在文章中并没有提及；B选项It may create more problems than it might solve。和原文最后的叙述很接近，是一个正确的选项；我们再看一下D选项Further research should be done before it is proved applicable，文章中说这种做法是可以的，但是会引起许多的问题，因此，不存在Further research的问题，所以这个选项不正确，因此，我们选B。
