1000CR Question No 1 : Test 16

(D) appears riht to me

Please explain your view.

harvesting the chanterelles growing beneath a Douglas fir seriously endangers the tree
The answer choice should cast a doubt or weaken this statement i.e we have to choose a statement
that doesn't imply ,endangering Douglas fir by Hravesting chanterelles . looking at answer choices

A) NO relation .
B) We are talking about harvesting Chanterlles growing specifically under Douglas fir , so this is irrelevant to the
context.
C) No relation.
D) It indicates harvesting mushrooms will stimulate growth of mushrooms and since mushrooms are source of nutrients
to Douglas fir . It implies harvesting will stimulate the growth of Douglas fir in a way hence weakening the original
conclusion drawan in passage.
E) It supports the argument rather than weakening it

I'm not sure I've understood why E is supporting the conclusion.

E says "Young Douglas fir seedlings die without the nutrients and water provided by chanterelle filaments. "...So chanterelle is actually helping in growth of Douglas fir & hence can't endanger the same.

Please point out the flaw in this reasoning.

The conclusion drawn in the passage is, "Because of this mutually beneficial relationship, harvesting the chanterelles growing beneath a Douglas fir seriously endangers the tree." We are looking for a statement that will weaken this conclusion, most likely by providing evidence that harvesting the chanterelles either will not affect, or will improve the health of, the Douglas fir tree.

Choice D casts doubt upon the conclusion. If the harvesting of wild mushrooms stimulates future growth of those mushrooms, then the Douglas fir will continue to be sustained by the "necessary sugars" provided by the new mushrooms. If this is the case, the trees will not be endangered--the opposite of the conclusion drawn in the passage.

In response to your question, samyak: Choice E supports the conclusion in the passage. E tells us that Douglas fir seedlings will die without the nutrients provided by the wild mushrooms; in other words, the lack of mushrooms will seriously endanger the tree. This is precisely the conclusion drawn in the passage, and thus is exactly the opposite of a correct answer choice.
