Guidebook writer:I have visited hotels throughout the country and have noticed that in those built before 1930 the quality of the original carpentry work is generally superior to that in hotels built afterward.Clearly carpenters working on hotels before 1930 typically worked with more skill, care, and effort than carpenters who have worked on hotels built subsequently.
Which of the following, if true, most seriously weakens the guidebook writer’s argument?
Which of the following most logically completes the argument?
The irradiation of food kills bacteria and thus retards spoilage.However, it also lowers the nutritional value of many foods.For example, irradiation destroys a significant percentage of whatever vitamin B1 a food may contain.Proponents of irradiation point out that irradiation is no worse in this respect than cooking.However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since _______.
many of the proponents of irradiation are food distributors who gain from food’s having a longer shelf life
it is clear that killing bacteria that may be present on food is not the only effect that irradiation has
cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods
certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is
for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded
