标题: [求助]OG-60
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. A

(E) Livestock producers claim that resistant bacteria in animals cannot be transmitted to people through infected meat.

不是很看的懂这题的加强方式，答案为A。

我是这样理解的。

题干：日常使用抗生素会提高抵抗细菌存活于抗生素环境的能力，因此抵抗细菌的出现可以归因于人们使用抗生素。然而一些科学家相信大部分人体中的抵抗细菌来源于人们所消耗的被感染细菌的肉。

A:抗生素被包含于家禽的日常饲料中，所以家禽饲养者可以增加这些动物的生长率。

似乎选项与题干没有太大关联啊。请哪为NN解释。
