HI akhilsuhag,
This CR question is based on a plan by Mammoth Industries. In these types of prompts, it's common for you to be asked to find a way to strengthen (prove that the plan will work) or weaken (prove that the plan won't work) the logic).
The Facts:
-Sales of telephones have INCREASED DRAMATICALLY over the LAST YEAR.
-To take advantage of the increase, Mammoth Industries is planning to do 2 things:
1) Expand its production of its model of telephone
2) Continue with its already extensive advertising of the telephone
The Plan:
-The first sentence tells us that sales of telephones (all telephones, not specifically the ones produced by Mammoth Industries) have increased dramatically. Mammoth clearly thinks that the trend will continue, so to take advantage, Mammoth is going to produce MORE of its telephone and continue with its extensive advertising of the telephone. Mammoth's idea is that since telephone sales are UP, then Mammoth should be able to sell more of its telephones.
We're asked to find an answer that offers a reason why Mammoth CANNOT INCREASE ITS telephone sales with this plan. The first thing I notice is the first sentence - just because telephone sales are up doesn't mean that Mammoth sold more of ITS telephones (or would sell more in the future), so I'd be looking for an answer that focused on THAT idea. If Mammoth is selling fewer telephones (for any reason over this last year), then the sales trend wouldn't likely help Mammoth to sell more telephones in the future. The only answer that addresses this issue is Answer E. Answer A tells us that Mammoth sold ALL of its phones, so there's some logic to say that the sales trend DID help Mammoth and will help it again. This is the opposite of what we're asked for.
