I think why there is a debate between (B) and (c),because some people don't recognize the real question it asked.
The question:Which of the following is most strongly supported by the information provided ?
That is to say: What can be concluded from the information provided above?
However, if the question changes: Which of the following most strongly support the argument above?
In my opinion ,the answer would be (B).
这题的思路是什么呀
B
不选E:原文有“ Lofgren’s disease has been observed frequently in commercially raised cattle but very rarely in chickens. ”既然都观察到了, 怎么能说“A failure to observe Lofgren’s disease “呢 ?所以,E不对。
这道题是说:鸡和牛都吃了带有病毒的饲料,可是可以观测到大量的牛得了L,却很少观测到鸡得L,why?因为,一般L的症状要在患病1年以后才显现,而鸡在饲养一年之内往往就被卖出去了。
题目的信息说明了,人们是依靠simptons的检测,观察到动物患L的。 在L显出simptons之前,也就是鸡被卖出去之前,是没有方法可以检测出鸡得了L的。(不然人们可以观测得到大量的鸡得病....)
讨论讨论中~~
我选C
