老师，我觉得这题条件1/2同时成立可以出结论。 因为条件二:X2＞XY，X2一定是正数，那么右边XY，Y＞0。所以X一定为大于0(因为一个正数不可能＜一个负数)。所以能推出结论选C.

In the Louisiana Purchase of 1803, the United States acquired 828,000 square miles for about four cents an acre, which more than doubled the country's size and that brought its western border within reach of the Pacific Ocean.
请唐瑭老师，或者王文静老师回答！谢谢！这里我主要的排除方法是看后面的more than doubling..是修饰谁的。我觉得是修饰828，000square，所以排除了ACE。剩下的BD我觉得都有毛病，但是D毛病轻点，就选了D了。再看回答案是C，我觉得后面的修饰只能就近refer到acre，这样我觉得意思不准确呀...请问我这样想对不对？

Editorial:
 
In Ledland, unemployed adults receive government assistance.  To reduce unemployment, the government proposes to supplement the income of those who accept jobs that pay less than government assistance, thus enabling employers to hire workers cheaply.  However, the supplement will not raise any worker's income above what government assistance would provide if he or she were not gainfully employed.  Therefore, unemployed people will have no financial incentive to accept jobs that would entitle them to the supplement.
 
Which of the following, if true about Ledland, most seriously weakens the argument of the editorial?

First-time computer buyers buying PXC home computers typically buy models that cost much less and have a smaller profit margin per computer than do PXC computers bought by people replacing their computers with more powerful models.  Last year PXC's profits from computer sales were substantially higher than the previous year, although about the same number of PXC computers were sold and the prices and profit margins for each computer model that PXC sells remained unchanged.
