Critical Reasoning

However, the new cork that our company developed, which will be adopted by the entire red wine industry, represents a solution. Since the new cork is natural and not treated with chemicals, when the industry completes its transition to the new cork, there will no longer be any threat to landfills from red wine corks.

Which of the following, if true, most weakens the argument above?

A) The industry's transition to the new red wine corks will take years, allowing thousands of old corks to pollute landfills.-Time no factor,it says when(bold-faced)
B) Even after the industry's transition to new corks, a large number of wine bottles with old corks will continue to be consumed.-Appropriate to the context.
C) The new corks take considerably longer to produce-.Time no factor,it says when(bold-faced)
D) Production of the new cork emits more toxic fumes than were emitted in the production of the old cork.-We are talking about landfills not the air.
E) The new corks are more expensive than the old corks.-PRice is not the issue

A) The industry's transition to the new red wine corks will take years, allowing thousands of old corks to pollute landfills.
Incorrect : This cannot weaken the argument because the company claims that there will no longer be any threat to landfills from red wine corks ONLY AFTER the transition from old corks to new corks.

B) Even after the industry's transition to new corks, a large number of wine bottles with old corks will continue to be consumed.
Correct : Since the company claims that the solution is only AFTER TRANSITION... this statement correctly undermines the argument by stating that even AFTER TRANSITION there will be a threat to landfills (from old corks)

C) The new corks take considerably longer to produce.
Incorrect : Time taken for production is not an issue here.

D) Production of the new cork emits more toxic fumes than were emitted in the production of the old cork.
Incorrect : Toxic fumes from old and new corks production does not undermine the conclusion that after the transition there will be no threat to landfills.

E) The new corks are more expensive than the old corks.
Incorrect : Price of new corks is irrelevant here.
