问题
A drug that is highly effective in treating many types of infection can, at present, be obtained only from the bark of the Ibora, a tree that is quite rare in the wild. It takes the bark of 5,000 trees to make one kilogram of the drug. It follows, therefore, that continued production of the drug must inevitably lead to the Ibora’s extinction. Which of the following, if true, most seriously weakens the argument above?
选项
A、The drug made from Ibora bark is dispensed to doctors from a central authority.
B、The drug made from Ibora bark is expensive to produce.
C、The leaves of the Ibora are used in a number of medical products.
D、The Ibora can be propagated from cuttings and grown under cultivation.
E、The Ibora generally grows in largely inaccessible places.
答案
D
解析
如果人类可以成功地种植Ibora,就可能在不威胁Ibora生存的情况下继续生产该药物,因此,选项(D)是正确答案;如果生产继续,生产出来以后分配该药物的方法[选项(A)]不可能仅凭此得到Ib一ora继续生存的结果;药物的价格[选项(B)]也不可能;如果Ibora的树叶也有用处[选项(C)],那么Ibora灭绝的危险增强了而不是减弱了;最后,如果Ibora大部分生长在人类无法到达的地方[选项(E)],这与该药物的生产是否能继续的问题有关,但与如果生产继续下去将发生什么无关。
