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?
Early exposure to malaria increases the body's resistance to it and results in a lesser likelihood of severe life-threatening episodes of malaria.
Mosquito bites can transmit to people diseases other than malaria.
Mosquito nets provide protection from some insect pests other than mosquitoes.
Although there are vaccines available for many childhood diseases, no vaccine has been developed that is effective against malaria.
The pesticides that are most effective against mosquitoes in regions where malaria is common have significant detrimental effects on human health.
纠结了C
但是发现违背了premise 肯定错
错选C：蚊帐可以为除了蚊子之外的其他昆虫提供保护，违背了premise
关于c的话， 感觉文中已经说过了文章可以防蚊子，这里说不能防在推翻文中的客观事实。
mosquito nets 蚊帐
A&C之间纠结
A选项说早暴露有抵抗力
C选项说蚊帐可以为除了蚊子之外的其他昆虫提供保护，但是这【违背了题干的premise】（ 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.）
因为单词不认识审错题了：reluctance 不情愿
A选项是提出了方案的副作用，小孩子的抵抗力下降
终于读懂题目问的是什么了！！！
问最强的根据来支持为啥官方不愿意推荐蚊帐：
答案A的意思是：早暴露在malaria的环境，可以增加抵抗力，减少得因malaria造成的重大疾病
错选E，文中说的是蚊帐，和杀虫剂无关。仔细读题！
reluctant 不知道意思错了 因果推理
就是 CQ1 其他原因
BCDE都是说应该用蚊帐，是削弱政府的行为
vaccines疫苗 detrimental有害的 reluctant 不愿意
P：mosquito nets over children's beds can significantly reduce the incidence of malarial infection
蚊帐能减少儿童疟疾
C：政府不愿意推荐蚊帐
问加强，相当于：解释这个转折
A：因为小时候得疟疾能加强抵抗力，正确
这道题说的是蚊子的nets可以reduce the chance of being bite，reduce the chance of getting malaria，而不是说bite可以reduce chance of getting malaria。脑子不清楚……
