Certain messenger molecules fight damage to the lungs from noxious air by telling the muscle cells encircling the lungs' airways to contract. This partially seals off the lungs. An asthma attack occurs when the messenger molecules are activated unnecessarily, in response to harmless things like pollen or household dust.
Which of the following, if true, points to the most serious flaw of a plan to develop a medication that would prevent asthma attacks by blocking receipt of any messages sent by the messenger molecules referred to above?

(A) Researchers do not yet know how the body produces the messenger molecules that trigger asthma attacks.
(B) Researchers do not yet know what makes one person’s messenger molecules more easily activated than another's.
(C) Such a medication would not become available for several years, because of long lead times in both development and manufacture.
(D) Such a medication would be unable to distinguish between messages triggered by pollen and household dust and messages triggered by noxious air.
(E) Such a medication would be a preventative only and would be unable to alleviate an asthma attack once it had started.
误选了E
求问大神这题的核心逻辑链是不是: blocking receipt of any messages--->prevent ashma attacks.
典型的方案推理吖..削弱方法就是可行性,有效性和副作用吖.
那按这个逻辑链的话D答案是有副作用,但是副作用并没有削弱prevent ashma attacks这个结论吖.
本质上D答案就是已经满足了prevent ahama attacks这个目的吖.不管会不会inhale那些noxious air
所以我觉得这题逻辑链是不是这个:develop medication that would prevent ashma attacks by blocking receipt--->(protect health).
感觉这样子否定性副作用削弱就说得通了?
求大神解释一题逻辑链到底是怎样..
还有求问关于helr大神的方案推理模式,那个否定性副作用的是要在作为削弱结论的副作用才可以选么??
thanks a lot!
按照GWD的说法,你能把你的中国人式的思维放一放吗?
such a medication would not become available for several years
这句话唯一告诉你的信息就是"这个药几年之内不会有",你怎么推出来“such a medication would become available after several years”的?
A--->B 为真
not A--->not B 一定为真?
真假不定啊!
