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 iboraâ€™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. (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.
If the Ibora can be grafted then mediacal botanists could easily be propogated in a controlled enviornment (most likely at a high cost however). Still (D) clearly weakens the central argument that the species would be made extinct.
in A if a cental authority controls extraction of timber than it is unlikely will lead the ibora tree to extinction in E if it is grows in inaccessible places than may be costs to acesss it would outweight the benefits of using it than it would not affect the tree. _________________

How is (E) not a good answer?
We are talking about extinction. If they can't access it, it will continue to exist.
D is good too.
Hi, E could imply that it is impossible to produce large quantities of drugs as the ibora would be difficult to obtain but to me it a very indirect and far fetched fact.
D is direct and to the central point.
It worries me what you mention that the CR100 has some/many errors, does anybody know of a list of known errors in the answers? I spent a lot of time thinking why I answered incorrectly when the OA seemed really wrong
Do you know if the SC & RC1000 have the same problem?
