The chanterelle, a type of wild mushroom, grows beneath host trees such as the Douglas fir, which provide it with necessary sugars. The underground filaments of chanterelles, which extract the sugars, in turn provide nutrients and water for their hosts.Because of this mutually beneficial relationship, harvesting the chanterelles growing beneath a Douglas fir seriously endangers the tree.

Which of the following, if true, casts the most doubt on the conclusion drawn above?

A The number of wild mushrooms harvested has increased in recent years.
B Chanterelles grow not only beneath Douglas firs but also beneath other host trees.
C Many types of wild mushrooms are found only in forests and cannot easily be grown elsewhere.
D The harvesting of wild mushrooms stimulates future growth of those mushrooms.
E Young Douglas fir seedlings die without the nutrients and water provided by chanterelle filaments.

I'll go with D. It attacks the reasoning that removing Wild mushrooms does not endanger the douglas fir trees. In fact, the removal of mushrooms paves way for more mushrooms to grow, which in turn can be implied as more water and nutrients for the fir.

In my opinion, the answer should be 'D'.

The passage is not concerned with the number of wild mushrooms, it is specific about chanterelle. So, 'A' is ruled out.

'B' supports as well as weakens the conclusion what if chanterelles endangers other tress also. This will actually support the author's conclusion.

'E' suggests that chanterlle is required for douglas seedlings which means that douglas seedlings should be sown at places where chanterlle is present. It does not actually effect the author's conclusion that chanterlle is harmful for douglas tree rather it talks about douglas seedlings.

The conclusion is based on the premise that douglas tree needs sugar which is extracted by chanterlle. 'D' weakens it by saying that wild mushroom harvesting stimulates the growth of other wild mushrooms which thereby means that chanterlle harvesting will stimulate chanterlle growth and thus will not extract sugar.

E Young Douglas fir seedlings die without the nutrients and water provided by chanterelle filaments.

I think its E .
A - not relevant
B - not relevant again
C - not relevant again
D - thats fine so its benefitting mushroom ..does it do anything with tree ...no
E - "Because of this mutually beneficial relationship, harvesting the chanterelles growing beneath a Douglas fir seriously endangers the tree." And E says seedlings will die without nutrients provided by mushroom. So mushrooms are good for douglas trees ..so its making the argument weak which says "endangers the tree"

E Young Douglas fir seedlings die without the nutrients and water provided by chanterelle filaments.

We need to weaken the conclusion so E is out because it strengthens the conclusion.

C: if anything strengthens.
B: irrelevant
A: irrelevant.

D: if harvesting these mushrooms increases the futher growth, then this benefits the tree even further.

Wow..this one really kicked my butt..I got confused with word "harvesting" .
Should be a clear D .
