Hi Guys,
I need help with the below CR question. Please post your choice along with the explanation.GMAT

instructors,please help!!!

Statement of a United States copper mining company: Import quotas should be imposed on the less expensive copper mined outside the country to maintain the price of copper in this country; otherwise, our companies will not be able to stay in business.
Response of a United States copper wire manufacturer: United States wire and cable manufacturers purchase about 70 percent of the copper mined in the United States. If the copper prices we pay are not at the international level, our sales will drop, and then the demand for United States copper will go down.
If the factual information presented by both companies is accurate, the best assessment of the logical relationship between the two arguments is that the wire manufacturer's argument
(A) is self-serving and irrelevant to the proposal of the mining company
(B) is circular, presupposing what it seeks to prove about the proposal of the mining company
(C) shows that the proposal of the mining company would have a negative effect on the mining company's own business
(D) fails to give a reason why the proposal of the mining company should not be put into effect to alleviate the concern of the mining company for staying in business
(E) establishes that even the mining company's business will prosper if the mining company's proposal is rejected

Cheers,

(A) is self-serving and irrelevant to the proposal of the mining company. This is my answer
(B) is circular, presupposing what it seeks to prove about the proposal of the mining company. Mining co is seeking for imposing import duty on imported mined copper whereas wire manufacturing co is concerned about prices at international level for its own benefit. So both are not related to each other. So eliminated
(C) shows that the proposal of the mining company would have a negative effect on the mining companyÃ¢â‚¬â„¢s own business. out of scope
(D) fails to give a reason why the proposal of the mining company should not be put into effect to alleviate the concern of the mining company for staying in business. copper wire co is not attempting to provide reason for not implementing mining co's proposal rather it is concerned about itself. so eliminated(E) establishes that even the mining companyÃ¢â‚¬â„¢s business will prosper if the mining companyÃ¢â‚¬â„¢s proposal is rejected. Irrelevant. against mining co's proposal.

Thanks Phirozz.Even in my view the answer should be A, but unfortunately the OA is C.

Now i am not able to understand the logic behind the OA.

Can i find some help from the GMAT instructors on this?

Answer is C only. OA is right. Last sentence of copper mining co's stamement create confusion, but we are looking from cable manufacturers' point of view. So its completely right.
thanx

Cheers,

Here is my take....

Mining company is favoring import quota for cheap imports
and Wire manufacturer is going for cheap prices of copper they get from international market...

as wire manufacturer says that they consume 70% of copper from US origin..
they use 30% from outside and if prices of 30% of copper will increase , the demand for
70% copper will also decrease ...due to lack of overall demand

SO proposal of Mining company will have negative impact on itself...

SO C is the ans

since the question asks us to look from the Wire manufacturer's perspective,
i believe C should be right.

For the same reasoning as above
70% domestic CU + 30% international CU = current cu cost is lower

70% domestic CU + 30% international CU ( NOW more expensive) = overall expense is more

which in turn might indicate that the demand is lowered, leading to an overall reduction in consumption.
this will affect US mining companies more.
