Does the decimal equivalent of P/Q, where P and Q are positive integers, contain only a finite number of nonzero digits?
(1)   P＞Q 
(2)   Q=8
contain only a finite number of nonzero digits 的意思应该是“非零数位的数目只是有限的"的意思吧，那么1／8＝0.125，小数点前有一个0，符不符合非零数位的要求啊？

In the United States, while the number of foreign-born residents and their children is higher than ever, the percentage of the population they represent is not; in 1910 this group made up 35 percent of the population when compared to 20 percent in 2000.
做的时候只剩A和E不知怎么比较，当时也纠结了很久，后来觉得E里面，compared with不知道是population还是前面指代整个一句话，有歧义，所以选了A。
