GWD1-40(TN版)

GWD1-Q40:

Until mow, only injectable vaccines against influenza have been available.  Parents are reluctant to subject children to the pain of injections, but adults, who are at risk of serious complications from influenza, are commonly vaccinated.  A new influenza vaccine, administered painlessly in a nasal spray, is effective for children.  However, since children seldom develop serious complications from influenza, no significant public health benefit would result from widespread vaccination of children using the nasal spray.

Which of the following is an assumption on which the argument depends?

A.      Any person who has received the injectable vaccine can safely receive the nasal-spray vaccine as well.

B.       The new vaccine uses the same mechanism to ward off influenza as jnjectable vaccines do.

C.      The injectable vaccine is affordable for all adults.

D.      Adults do not contract influenza primarily from children who have influenza.

E.       The nasal spray vaccine is mot effective when administered to adults.

答案是D. 为什么?

我觉得是E,因为对大人无效果,而小孩又不太会发展到serious complications,所以没有利益。

请牛牛们指点!!!

大人会因为流感得并发症,所以注射疫苗,(并不是感冒可怕,而是并发症可怕)小孩并不会由于感冒得并发症因而。
如果大人不会因为儿童没有预防感冒而导致感冒从而得了并发症,那么儿童使用喷雾剂预防疫苗就没有意义了,因为谁都不会得到真正可怕的并发症。
benefit应该不是只经济利益,是福利。
并且D错在无关,喷雾对大人有没有用都无所谓,因为大人有注射剂。
