GWD-9-Q12:

A mosquito bite can transmit to a person the parasite that causes malaria, and the use of mosquito nets over children’s beds can significantly reduce the incidence of malarial infection for children in areas where malaria is common. Yet public health officials are reluctant to recommend the use of mosquito nets over children’s beds in such areas.

Which of the following, if true, would provide the strongest grounds for the public health officials’ reluctance?

 

A.    Early exposure to malaria increases the body’s resistance to it and results in a lesser likelihood of severe life-threatening episodes of malaria.

B.    Mosquito bites can transmit to people diseases other than malaria.

C.    Mosquito nets provide protection from some insect pests other than mosquitoes.

D.    Although there are vaccines available for many childhood diseases, no vaccine has been developed that is effective against malaria.

E.     The pesticides that are most effective against mosquitoes in regions where malaria is common have significant detrimental effects on human health.

为什么E比D好呢？

我觉得D是 在题意A=>B的基础上说，没有B很严重，所以support

而E是在题意A=>B的基础上说，还有C=>B但不好，所以support

对么？

不明白 文章讲蚊帐答案讲杀虫剂？？

討論一下 為何我不會選D

題目在說 蚊帳有效 但 專家很猶豫

所以 推論是:  蚊帳 -> 減少被叮咬 -> 減少疾病傳染

所以weaken 這個結論 就等同於 專家的猶豫支持這個結論

也就是說我們的 "目標推論" 變成:  

     

              其實某某東西也可以 -> 減少被叮咬 -> 減少疾病傳染

答案D 是說 有疫苗但是不是很有效, 因此 不是一個也能支持我們目標論點的東西.

因此 只有答案E, 是符合我們目標論點的. pesticides 可以殺蚊 減少叮咬 減少疾病傳染.

答案A 是否定整個論點, 說明被叮咬也有幫助, 是比較有風險的選項 討論範圍更廣. 我不太敢選.

TKS!
