Countries that legalized the drug X twenty years ago, because

a significant percentage of the population had been using X on a daily basis without any apparent harm to the community at large, reset the benchmark for what is appropriate and proper behavior among their citizens. Since X's legalization, there has been an increase in manic depression, suicide and certain kinds of cancer. In order for Andovia, a country that has not yet legalized X,to avoid the development of such undesirable tendencies and prevent the social problems stemming from broad usage of drug X, it should close its borders and not issue visas to any tourists from countries where drug X is legal.

Which of the following, if true, most seriously weakens the argument above?

    A.Drug X emits a faint smell that makes it very difficult for trained canines to identify at border
    control points.

    B.The detrimental side effects of drug X only become visible after several years of usage.  

    C.Andovia is surrounded on three sides by water, but has an excellent naval border police force.  

    D.Drug X resembles several other designer drugs currently on the market.  

    E.Drug X is very easy to extract chemically from certain consumer products and is taken in droplet size doses that can easily be camouflaged as items such as hairspray or nail polish remover.

答案:
E

X这种药

一些国家合法使用后产生了一些自杀癌症等影响,A国还没使X合法化,为了避免这些不良影响,决定控制X的使用,不让X合法的那些国家的人进来。问削弱

A  X释放的气体让警犬很难识别,错,文章说的是不给那些人发护照,所以跟X释放气体无关

B  X的副作用在几年后才产生,错,A这个国家还是要采取措施,不能削弱

C  A国边防力量强,增强

D X和其他药很像,无关信息

E X在一些产品中能提取出来,而且很容易被伪装成头发喷雾或者卸甲水的样子,这样X就很容易在当地就被生产,正确
