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?
Researchers do not yet know how the body produces the messenger molecules that trigger asthma attacks.
Researchers do not yet know what makes one person's messenger molecules more easily activated than another's.
Such a medication would not become available for several years, because of long lead times in both development and manufacture.
Such a medication would be unable to distinguish between messages triggered by pollen and household dust and messages triggered by noxious air.
Such a medication would be a preventative only and would be unable to alleviate an asthma attack once it had started.
GWD居然说选E选项，尴尬😅问了国外的论坛也说选D。
错选E，无关选项，题目中说只要prevent就可以，但是是否able to alleviate 不在考虑范围内
某些信使分子通过告诉环绕肺部的肌肉细胞收缩来对抗有害气体对肺部的伤害。这部分封闭了肺部。当信使分子被不必要地激活时，就会发生哮喘发作，以应对花粉或家庭灰尘等无害物质。
因此，推出了一种药物可以阻止接收信使分子发出的任何信息，问这种药物最严重的缺陷是什么？
组织了任何信息表明无论是有害的还是无害的都被阻止了
