Which of the following, if true, indicates that there is a major flaw in the argument above?
(A) Fresh potatoes bought in convenient 2-pound bags are about $1 a bag, or 2 1/2 times more expensive than fresh potatoes bought in 10-pound bags.
(B) Since fresh potatoes are 80 percent water, one pound of dehydrated potatoes is the equivalent of 5 pounds of fresh potatoes.
(C) Peeled potatoes in cans are also more expensive than the less convenient fresh potatoes.
(D) Retail prices of dehydrated potatoes have declined by 20 percent since 1960 to the current level of about $3 a pound.
(E) As a consequence of labor and processing costs, all convenience foods cost more than the basic foods from which they are derived.

According to PowerScore CR Bible, this question belongs to family 2. i.e. we need to find the flaw in the conclusion by considering each answer choice as 100% correct.

If we look at the choice (B), it states that

1 Pound of Dehydrated potatoes = 5 pound of fresh potatoes.

That means, 2 pound of dehydrated potatoes = 10 pound of fresh potatoes. It means consumer will pay actually paying 6$ for the equivalent of 10 pounds of fresh potatoes. So, rate is increased by 3 times instead of 15 times.

Hence choose (B)

Option (C) is out of scope, because it talks about Peeled potatoes, which is out of scope in this context.

Hope this helps...

Reason you have given, looks like you are supporting the argument.
