陈向东逻辑-解释-抗生素与免疫系统

evelyn205205

Studies have shown that people who rarely take antibiotics, which are antibacterial drugs, have stronger immune systems than do people who take antibiotics frequently. Yet there is no evidence that taking antibiotics weakens the immune system.

Which of the following, if true, best reconciles the apparent discrepancy in the information above?

(A) People who have strong immune systems seldom get the kinds of infections for which people normally take antibiotics.
(B) People who have strong immune systems are seldom aware that their immune systems are unusually strong.
(C) People who have weak immune systems have great difficulty recovering from bacterial infections if they do not take antibiotics.
(D) Some people take antibiotics even though the antibiotics cause a variety of side effects.
(E) Some people take antibiotics frequently because their doctors prescribe antibiotics for viral infections as well as for bacterial infections.

答案是A。
我选的是C。我是这样理解C的：不是antibiotics削弱了免疫系统，而是有可能那些免疫系统差的人本身就需要这些抗生素来抵抗外界病毒的侵袭。我是以反向推理来解释这道题的。
以前在削弱里就有运用到类似方法的题，即题目中说是A推出B，那么削弱可以是证明说其实是B推出A的。
于是，我就运用这样的概念，不知道哪里出问题了，为什么不对？
NN们，来帮帮我吧~I'd be appreciated！！！

少吃药的人免疫好过常吃药的人，一看到这个，如果自己推理，就会想到：
1）是吃药了，导致免疫降低
2)  免疫好的人本身 身体就好，而免疫差的人本身身体就差 （所以才不得不吃药来恢复－－选项c是吃药的原因)

文章内已经排除了1），所以答案是2）免疫高的人不是因为吃药少，是因为本身身体就好（很少传染上＊＊＊＊疾病－－选项a)

我选的也是C。。。我也想了好久，觉得可能有两个原因，一个是题目中本身就强调少抗生素，强免疫系统，而不是反过来，另外一个就是C里面的bacterial infection 实际上是新的概念啊，所以相比之下就选A了吧。。。。

为什么选A，而C不对？

我怎么觉得A和C讲得都是一个意思呢 它们都是说其实是因为人的weak/strong immune system 才导致要多吃/少吃 antibiotic
