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.

为什么C不对啊?抗药性细菌在城市人中高于在农村人中正因为rural的meat质量好,不正说明meat是原因吗?大家快帮帮我吧

题干：吃抗生素→病菌抗药性

      吃肉→病菌抗药性

所以要建立肉与抗生素的关系，与肉的质量无关。

明白了,C中的肉并没有说含不含抗生素. 多谢!

对，是个FOCUS问题。城里城外不是重点。

C选项最好还是按照OG的解释: 城内城外差异(假设两地肉的品质相同), 因此提供另一个解释:地区差异可能才是影响因素, 吃肉不是主因。有weaken scientists說法的效力。

Choice C suggests that meat consumption is not the primary culprit (罪犯) for the high incidence of resistant bacteria.
