To reduce the number of people who fall ill from eating undercooked chicken, Halvern's food safety agency plans to require that all raw chicken sold in shops carry a label stating the safe internal cooking temperature. The agency notes that most such illnesses result from chicken cooked at home and that surveys show most home cooks do not know the safe temperature. Moreover, households in which the cook does know the safe temperature report far fewer such illnesses than other households. The agency therefore predicts that the labels will substantially reduce these illnesses.
Which of the following, if true, most seriously weakens the agency's prediction?
A. In Halvern, most home cooks who know the safe temperature own a meat thermometer, whereas very few other home cooks own one.
B. A significant minority of these illnesses in Halvern are traced to chicken served in restaurants rather than to chicken cooked in the home.
C. Most home cooks who know the safe temperature report having learned it from cookbooks, television programs, or cooking classes.
D. Printing the required labels will add slightly to the cost of packaging, and shops are expected to pass that cost on to their customers.
E. In a neighboring country that adopted a similar labeling requirement, the number of such illnesses declined during the following year.

Plan: Show safe temperature information in labelling
Effect: Reduced illness
How: Household cooks who knew safe temp have fewer illness
What will weaken this?
Which of the following, if true, most seriously weakens the agency's prediction?
A. In Halvern, most home cooks who know the safe temperature own a meat thermometer, whereas very few other home cooks own one. This directly brings in additional info that says cooks, even though they knew the safe temp, had no means of measuring it.
B. A significant minority of these illnesses in Halvern are traced to chicken served in restaurants rather than to chicken cooked in the home.-- Significant minority will not impact most
C. Most home cooks who know the safe temperature report having learned it from cookbooks, television programs, or cooking classes.-->Irrelevant
D. Printing the required labels will add slightly to the cost of packaging, and shops are expected to pass that cost on to their customers.- Irrelevant
E. In a neighboring country that adopted a similar labeling requirement, the number of such illnesses declined during the following year.- Additional information but of no weakening impact, strengthens the expression slightly

Which of the following, if true, most seriously weakens the agency's prediction?
The agency assumes that teaching cooks the safe temperature will itself substantially reduce illness. That inference is weakened if another factor explains why knowledgeable cooks have fewer illnesses.
(A) In Halvern, most home cooks who know the safe temperature own a meat thermometer, whereas very few other home cooks own one.
Correct. This provides an alternative explanation for the lower illness rate. The important factor may be having a thermometer, not merely knowing the safe temperature. If labels increase knowledge but cooks still cannot measure the temperature, the labels may have little effect.
(B) A significant minority of these illnesses in Halvern are traced to chicken served in restaurants rather than to chicken cooked in the home.
Incorrect. The passage already says most illnesses result from chicken cooked at home, so the labels could still substantially reduce the majority of cases.
(C) Most home cooks who know the safe temperature report having learned it from cookbooks, television programs, or cooking classes.
Incorrect. This explains where they learned the temperature, but it does not suggest that labels would be ineffective.
(D) Printing the required labels will add slightly to the cost of packaging, and shops are expected to pass that cost on to their customers.
Incorrect. A slight price increase does not show that the labels will fail to reduce illness.
(E) In a neighboring country that adopted a similar labeling requirement, the number of such illnesses declined during the following year.
Incorrect. This supports rather than weakens the prediction.
