GWD1-Q40

GWD1-Q40:

Until now, 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D  为什么E不对

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.

小弟的淺見....

因為題目最後結論說道...小孩子並不常衍生出嚴重的併發症, 所以使用這種噴鼻劑的疫苗, 就沒有顯著來推廣這種疫苗的公共衛生利益

but adults, who are at risk of serious complications from influenza, are commonly vaccinated.

but adults, who are at risk of serious complications from influenza, are commonly vaccinated.

但前提說道...成年人比較有衍生出併發症的高風險

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

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

所以如果要產生顯著的公共衛生利益就必須對成年人有顯著影響...但是

結論提到並沒有顯著的公共衛生利益, 所以要支持這各結論就必須有

(D)這個答案的假設囉!!!

(E)本題並沒有提到這噴鼻疫苗對成年人有沒有效用!!!

歡迎大家來討論!! 謝謝!!

可不可以这样理解阿？（因为我选的也是E，但是当时是D和E想了半天才选的E。）

如果是D的话，取非D可得：大人从小孩那边传染---->significant public health benefit would result from widespread vaccination of children. 但是这个返回条件去看，children seldom develop ....->怎么可能有那么多大人的这个病呢？更不用提这个vaccine的作用。所以我排出了D.

但是E我觉得也有问题。毕竟if vaccine is effective when administered to adults------>significant publich health benefit..而结论中还有一项是from widespread vaccination of children using the nasal spray.

真是纠结阿~~~既然prep说E，我们只能这样强求了！！看看大家是否有其他的思路？？

我看PREP的答案也是D啊。

题目说no significant public health benefit would result from widespread vaccination of children using the nasal spray.

E 选项说对大人有效似乎无关;及便没有上面的红字，E的意思似乎也在削弱，而不构成assumption
