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.

答案A，我怎么觉得A不对，但也没有哪个选项是对的

原文结论：因为吃了受感染的肉才产生抗体的

A： 抗生素被用于家畜喂养中，以此来提高家畜的生长速度。 （肉受感染了，支持）

打了抗生素的家畜的肉怎么会就是bacterially infected meat的呢

这是我不明白的地方

Since antibiotics can give rise to resistant bacteria capable of surviving antibiotic environments.

明白了，呵呵

谢谢

这个岂不是要求答题人要有题目给出信息额外的知识了
