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.

正确答案是A，可以理解，可是B为什么错？

OG的解释是How cases of food poisoning are treated (choice B) fails to indicate whether the infecting bacteria are resistant bacteria 不理解！！！

文中不是有the presence of resistant bacteria in people could be due to the human use of prescription antibiotics，如果B成立，因为吃了bacterially infected meat 所以食物中毒，所以用prescription antibiotics治疗，不是正可以推出结论么？

"most resistant bacteria in people derive from human consumption of
bacterially infected meat" 这句言下之意则为 food poisoning.但并不是所有food poisoning
都由 bacteria infected meat 所造成，因此the treatment of food poisoning can't
be the same with the treatment of resistant bacteria.  Therefore,
B is not the answer

仰望星空

Most people who develop food poisoning from bacterially infected meat are treated with prescription antibiotics

这里的MOST修饰的是吃污染肉的人。而不是修饰所有的人。

选项的意思是大多数吃污染肉的人用抗生素治疗。没有解释那些没有吃污染肉的人的体内细菌抗药性的问题。

我市今天第一次看题，不知道说清楚没。

看了IAWFY的帖子，终于明白了！谢谢！

(B) Most people who develop food poisoning from bacterially infected meat are treated with prescription antibiotics.

人是先吃细菌感染的肉才食物中毒  才用抗生素治疗  肉里面没有抗生素

    

Some scientists, however, believe that most resistant bacteria in
people derive from human consumption of bacterially infected meat.

    

假设是说  人食用含有抗生素的肉

    

这样一比 B就无关了

丫丫兔

从B中看出顺序，得出结论，赞！

豁然开朗，原来逻辑中阅读能力还是相当重要的吖。

C为什么不对 A中并没有说有很多人吃肉 肉中病毒多不一定导致很多人生病啊
