C.are overoptimistic about the safety of the food they eat
D.overstate the Government’s interference with the food industry
正确答案：A
解析：The opening sentence states: ‘Many Americans harbor a grossly distorted and exaggerated view of most of the risks surrounding food.’ ‘Distorted and exaggerated’ directly corresponds to ‘overestimate’. Fergus Clydesdale’s quote about streets being ‘littered with people’ further underscores the exaggeration.
解析：The passage states: ‘Bruce Ames… points out that up to 10% of a plant’s weight is made up of natural pesticides’ and ‘many naturally produced chemicals… prove… to be strong carcinogens’. It explicitly says: ‘Mushrooms might be banned if they were judged by the same standards that apply to food additives’ — emphasizing inherent natural danger, not just man-made contamination.
8.By saying “they employ chemical warfare” (Para. 2), Bruce Ames means _.
A.plants make use of natural chemicals to promote their growth
B.plants produce certain chemicals to combat pests and diseases
C.farmers use man-made chemicals to dissolve the natural chemicals in plants
D.farmers use man-made chemicals to protect plants against pests and diseases
正确答案：B
解析：The sentence before reads: ‘Since plants do not have jaws or teeth to protect themselves, they employ chemical warfare.’ This is a metaphor for endogenous defense mechanisms — i.e., plants synthesize natural toxins (e.g., alkaloids, cyanogenic glycosides) to deter herbivores and pathogens.
