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.
题目:抗生素可以增强抵制细菌,吃抗生素可以表现出抵制细菌。但是科学家认为:
抵制细菌可以从吃由细菌污染的猪肉里获得
答案:抗生素包括在家禽饲养,所以家禽生产者可以提高家禽的生长率
我弄不明白题目和答案之间的关系,请大家指教
up!希望路过的人不吝赐教哦!
经常使用抗生素可以增加细菌在抗生素环境下的生存能力,这种细菌在人体中的存在归因于人们使用了抗生素。但是科学家认为这种细菌在人体中的存在源于人们消费了细菌感染的肉。
A说抗生素通常使用在家畜的饲料当中.
这道题的难点在于答案看起来与题目无关。
答案A前半句说给牲畜吃得饲料中有抗生素
后半句说是为了让它们长得更快,ETS的
阴险就在这里。前半句是答案(因为它指出了
人体内的对细菌的抵抗力是来自人吃得肉与科学家的
观点一致),后半句是无关
的干扰,让你很容易将真正的答案否定!
同志们小心!
Had an impression that the answer should say resistance is from bacteria/meat but not from antibiotics. But the stem says: prescription antibiotics vs meat.
ETS put “bacterially infected” and “increase the growth rate” as confusion.
The correct answer could also be: non-prescription antibiotic is the reason.
