问题 Since the routine use of antibiotics can give rise to resistant bacteria capable of surviving antibiotic environments, the presence of resistant bacteria in people could be due to the human use of prescription antibiotics. Some scientists, however, believe that most resistant bacteria in people derive from human consumption of bacterially infected meat. Which of the following statements, if true, would most significantly strengthen the hypothesis of the scientists?

选项 A、Antibiotics are routinely included in livestock feed so that livestock producers can increase the rate of growth of their animals.
B、Most people who develop food poisoning from bacterially infected meat are treated with prescription antibiotics.
C、The incidence of resistant bacteria in people has tended to be much higher in urban areas than in rural areas where meat is of comparable quality.
D、People who have never taken prescription antibiotics are those least likely to develop resistant bacteria.
E、Livestock producers claim that resistant bacteria in animals cannot be transmitted to people through infected meat.

答案 A

解析 如果牲畜通常喂有抗生素,如选项(A)指出的,由于任何常规的抗生素使用会产生抗生菌,牲畜的肉可能含有抗生菌,因此选项(A)是正确答案;食物中毒的情况是如何治疗的[选项(B)]没有指明感染的细菌是否是抗生菌;选项(C)指出肉类的食用不是抗生菌高发现率的首要嫌疑;选项(D)有助于支持处方抗生素应为此负责这一相对立的假想;选项(E)指出畜牧业主宣称该假想是错误的,但没有提供基础来评价这一宣称的真实性。
