skumar Posted June 21, 2005 Share Posted June 21, 2005 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? (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. © 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.

skumar Posted June 22, 2005 Author Share Posted June 22, 2005 well the OA says E...I too am not convinced though..... Quote Link to comment Share on other sites More sharing options...
alex_cute Posted June 22, 2005 Share Posted June 22, 2005 I think E is clearly wrong. D is much stronger. In the absence of D E is the second best answer. Quote Link to comment Share on other sites More sharing options...
