The use of growth-promoting antibiotics in hog farming can weaken their effectiveness in treating humans because such use can spread resistance to those antibiotics among microorganisms. But now the Smee Company, one of the largest pork marketers, may stop buying pork raised on feed containing these antibiotics in order to avoid jeopardizing their sales. So if Smee makes this change, it will probably significantly slow the decline in antibiotics’ effectiveness for humans.
Which of the following, if true, would most strengthen the argument above?
Other major pork marketers will probably stop buying pork raised on feed containing growth-promoting antibiotics if Smee no longer buys such pork.
The decline in hog growth due to discontinuation of antibiotics can be offset bu improved hygiene.
Authorities are promoting the use of antibiotics to which microorganisms have nor yet developed resistance.
A phaseour of use of antibiotics for hogs in one country reduced usage by over 50 percent over five years.
If Smee stops buying pork raised with antibiotics, the firm's costs will probably increase.
如果SC不买抗生素的猪肉，结论是使得抗生素对人体的有效性的下降变得缓慢。就是让抗生素还能对人体有好处可以抵御微生物。
方案推理
A 其他的厂家也不会买这些猪肉了。加强了结论，因为市场上卖的都是不含抗生素的了，自然微生物抗药性就不会形成了
B 提高卫生水平 无关方案
C 无关方案
D 无关方案 减少剂量50% 可能50%也足够产生抗药性了
E 不关心成本
