Question ID:PT35 S1 Q6 Passage:Proponent:  Irradiation of food by gamma rays would keep it from spoiling before it reaches the consumer in food stores.  The process leaves no radiation behind, and vitamin losses are comparable to those that occur in cooking, so there is no reason to reject irradiation on the grounds of nutrition or safety.  Indeed, it kills harmful Salmonella bacteria, which in contaminated poultry have caused serious illness to consumers.Opponent:  The irradiation process has no effect on the bacteria that cause botulism, a very serious form of food poisoning, while those that cause bad odors that would warn consumers of botulism are killed.  Moreover, Salmonella and the bacteria that cause botulism can easily be killed in poultry by using a safe chemical dip. Stem:Which one of the following could the opponent properly cite as indicating a flaw in the proponent's reasoning concerning vitamin losses? Correct Answer Choice:BChoice A:After irradiation, food might still spoil if kept in storage for a long time after being purchased by the consumer. Choice B:Irradiated food would still need cooking, or, if eaten raw, it would not have the vitamin advantage of raw food. Choice C:Vitamin loss is a separate issue from safety. Choice D:Vitamins can be ingested in pill form as well as in foods. Choice E:That food does not spoil before it can be offered to the consumer is primarily a benefit to the seller, not to the consumer.
