Critical or Logical Reasoning: Critical or Logical Reasoning Practice MCQ

Question Statement:

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?

The drug made from borax bark is dispensed to doctors from a central authority.

The drug made from borax bark is expensive to produce.

The leaves of the ibora are used in a number of medical products.

The ibora can be propagated from cuttings and grown under cultivation.

The ibora generally grows in largely inaccessible places.

Explanation:

Correct Answer: D

Option A : The method of the drug's distribution is irrelevant, unless the central authority can limit the drug's production from the bark of wild ibora trees. But this information is not provided.

Option B : The cost of producing the drug does notaffect the outcome for the treeunless it deters production.

Option C : The existence of uses for other parts of the tree opens the possibility that the ibora-bark drug would cause no increase in destruction of trees other than what exists already. If this information were provided, it would weaken support for the conclusion. Since it is not provided, this option does not significantly weaken the argument.

Option D : Correct. This information most weakens the argument.

Option E : Difficulty of access to the trees could provide a disincentive to their harvesting—but we are not told that it would prevent their harvesting.

The correct answer is D.
