60. 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?

(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

原文逻辑链： 抗生素产生具有抗体的细菌，具有抗体的细菌存在于人体是由于人们服用处方抗生素

                      一些科学家指出，人们身体里的抗体细菌来自受到感染的肉

问支持科学家假设的是哪个选项

A 抗生素被加入饲料中以提高动物的生长速度 - 动物含有抗体细菌 - 人吃了也会有这种细菌

我觉得这个答案有逻辑推理GAP，动物体内存在抗体细菌不代表人吃了就一定会有啊，选项E不正是给我们提了个醒么

附上OG解释，还有这个routinely不太明白，不知道是不是这里出了问题

60.

If livestock are routinely fed antibiotics, as choice A states, meat from livestock is likely to contain the resistant bacteria, since any routine of antibiotics can result in resistant bacteria. Thus, choice A is the best answer.
