某个地方发现某一种加工材料里面铅(lead)过高,铅对孩纸的脑子会有影响让他们的一种病,所以政府禁止使用这种加工材料,但是N年后得这种脑子病的的孩纸数目反而增加了,因为?
之前做练习的时候答案是因为这些铅会渗入土壤,而孩纸夏天喜欢光脚玩所以体内铅含量增加
这次很悲剧选项全部重新换过了,卤煮看着唯一一个比较顺眼的就是:用这种铅超标的材料建造的房子会向空气中释放铅,孩纸们呼吸就会吸入过量的铅。
PREP疑似:
In Arumville, among those young children with elevated levels of lead in their blood, few live in houses containing lead-based paint, but many live in areas where vehicular traffic is heavy.These children's elevated blood-lead levels probably result from lead added to gasoline, since, although gasoline sold in and around Arumville has been lead-free since 1990, lead from vehicle exhaust remains in the soil for many years.
Which of the following, if true, most strengthens the argument?
A. Sales of lead-based paint for use in homes was banned in Arumville in 1977.
B. Vehicle traffic in most residential areas of Arumville is heavier today than it was twenty years ago.
C. Some lead in the soil comes from deteriorating lead-based paint on the exteriors of buildings.
D. In Arumville, children's blood-lead levels typically rise during the warm summer months when children frequently play outdoors but not in the winter when children spend more time indoors.
E. If improperly carried out, the removal of lead-based paint from older houses can significantly increase the risk that children living in such houses will ingest lead dust.
感谢小伙伴提供情报~
