在最近的将来，什么是公众在和科学相关的问题上应做的决定呢?迄今为止最紧急的有关核武器的决定。其他的全球问题，诸如食物供给或者温室效应则是相对迟缓的，核战争意味着地球的全人类在几天内被消灭。冷战结束带来的东西方紧张关系的缓解表明，核战争的恐惧已从公众意识中退出。但是只要还存在可以把全球人口消灭许多遍的武器，这种危险仍然在那里。即使我们避免了核战争，仍然存在把我们消灭的其他危险。有人讲过一个恶毒的笑话，说我们之所以未被外星人文明所接触，是因为当他们的文明接触到地球时总是自己先被消灭掉了。但是我对公众的意识有充分的信任，那就是相信我们能够证明这个笑话是荒谬的。综观全文，对最后一句话的理解，错误的一项是：( )。A.
相信我们能够很好地解决酸雨及温室效应等问题，实现生态的可持续发展
B.
相信我们能够很好地解决核武器和遗传工程所带来的危机，实现地球的真正和平
C.
相信我们能够很好地解决食物供给和遗传工程等难题，确保地球人自身的可持续发展
D.
相信公众在和科学相关的问题上能够做出明智的决定，能够消除一切“把我们消灭”的“危险”，让“恶毒的笑话”不攻自破
