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.

Conclusion: that continued production of the drug must inevitably lead to the iboraâ€™s extinction.
Assumptions:
That drug is made only from Ibora tree
Number of trees grown proportion is less compared trees being cut for making the drug

Let me try analyzing the options:
(A) The drug made from ibora bark is dispensed to doctors from a central authority. - Irrelevant - Dispensed to doctor from central authority has nothing to do with the extenction of the tree
(B) The drug made from ibora bark is expensive to produce. - Out of scope - Expensive to produce - But this have nothing to with distinction. Even if its extensive the drun will be made and info expensive is out of scope
(C) The leaves of the ibora are used in a number of medical products. - May be strengthener - becuase the leaves are used in number of medical products which help in extenction of this Ibora tree
(D) The ibora can be propagated from cuttings and grown under cultivation. - Good weakener - Because if these trees are grown in cultiavation then this can give an alternate view for the Ibora extinction i.e. Conclusion
(E) The ibora generally grows in largely inaccessible places - Irreveleant

We need to weaken the conclusion, so if we can grow trees by any other method then there is no question of extinction.

We need to weaken the conclusion, so if we can grow trees by any other method then there is no question of extinction.

The question stem is "Which of the following, if true, most seriously weakens the argument above?" So, We can safely assume that the option can be considered to be true.

Moreover, The option says largely inaccessible places NOT completely ! So, The drug was made with accessible area.And if there will be there in inaccessible area then it cant extinct.

I agree that D is also a weakener but i want to know why E is wrong ?

Focus on Argument:
Premise 1: 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. Premise 2: It takes the bark of 5,000 trees to make one kilogram of the drug.
Conclusion : It follows, therefore, that continued production of the drug must inevitably lead to the iboraâ€™s extinction.

Now lets prethink that what author assumes while concluding his conclusion

- There is not any Law that prohibit cutting of trees
- There not any possibility for a new method by which that can be made in near future.
- There is no possibility for growing trees.

Now attack on the assumptions of author to weaken conclusion. Additionally answer choice must present some new relevant information.

Thanks Him1985 for putting so much efforts.I really appreciate that.Kudos to you.

I think i get it now. The key here is "continued production of the drug".I didn't take that into account and fell for the catch.

Thanks,
Varun

I first thought it was E. However, D seems to make more sense than E.

But the fact that these trees are growing at inaccessible places, can also means that these trees cannot be easily cut, which prevents extinction?
