93
P:states that countries closed out of any of anothercountry’s markets should close some of their own markets to the other country
C:no country would trade with any other
就是说每个被制裁的国家都应该报复。。这样的话冤冤相报大家都别trade了
所以如果最开始没有一个国家制裁别的国家，那么后边的所有事情都不会发生咯

106
Facts:proportion of schoolchildren sent for treatment of allergic reactions to those chemicals has increased
Exp:either Renston’s schoolchildren have been exposed to greater quantities of the chemicals, or they are more sensitive to them
B 题中说的是对those chemicals过敏，不讨论其他
C 就是说现在的孩子更矫情了。。过敏了就会到医务室，而原来的孩子可能过敏了但是不会去。这样也可能在实际过敏人数不变的情况下导致看病人数上升
D跟common不common没有关系吧

93. d 选项 For any two countries,at least one has some market closed to the other.
at least one 至少有一个，取非就是一个都没有，就是任意两个国家都没有对对方关闭市场，削弱了结论
