First-time computer buyers buyingPXC home computers typically buy models that cost much less and have a smallerprofit margin per computer than do PXC computers bought by people replacingtheir computers with more powerful models. Last year PXC's profits from computer sales were substantially higherthan the previous year, although about the same number of PXC computers weresold and the prices and profit margins for each computer model that PXC sellsremained unchanged.

(A) PXC's competitors raised theprices on their computers last year, making PXC computers more attractive tofirst-time computer buyers.

原文意思是，第一次买电脑的人一般会选择比较便宜的型号，而买电脑来取代旧电脑的人会选择比较贵的。PXC去年与前年销售电脑的数量差不多，每个型号的售价和毛利率也没有发生变化。但PXC去年的利润比前年高。
答案应该是d，因为第一次买电脑的人的比例去年比前年低。
