Metropolis' regulation limiting to four days the period during which milk can be sold to consumers after pasteurization is unreasonable. Under optimal conditions, pasteurized milk kept at 40 degrees Fahrenheit remains unspoiled for at least 14 days. If Metropolis' current limitation were changed to eight days, milk prices would drop, but product quality would be unaffected.
Which of the following, if true, would most seriously weaken the conclusion drawn above?
(A) Most consumers keep milk no more than three days after purchase.
(B) A recent survey showed that 20 percent of Metropolis consumers favored extending the current limitation on the sale of milk to 8 days.
(C) Metropolis' grocery-store owners would prefer small, frequent deliveries of milk to larger, infrequent deliveries.
(D) Milk kept longer than 14 days after pasteurization generally presents no medical dangers if consumed.
(E) In Metropolis, conditions for handling and storing milk after pasteurization are seldom close to optimum.
Which of the following, if true, would most seriously weaken the conclusion drawn above?
(A) Most consumers keep milk no more than three days after purchase.
(B) A recent survey showed that 20 percent of Metropolis consumers favored extending the current limitation on the sale of milk to 8 days.
(C) Metropolis' grocery-store owners would prefer small, frequent deliveries of milk to larger, infrequent deliveries.
(D) Milk kept longer than 14 days after pasteurization generally presents no medical dangers if consumed.
(E) In Metropolis, conditions for handling and storing milk after pasteurization are seldom close to optimum.

The right answer here is E
This is a weaken question, our first task is to identify the conclusion. Here it's the following: Limitation changed to 8 days => Milk price drops BUT quality unchanged.
A - This is nice, but OUT OF SCOPE.
B - This doesn't affect the conclusion about price and quality -> OUT
C - Do we care about grocery stores here? Nothing about limitation, nor quality, nor price -> OUT
D - Price or quality here? It's way out of scope about medical dangers -> OUT
E - Haha, and this one is a good one! With different bad storing conditions the quality will eventually change, seems legit -> CORRECT
