In January there was a large drop in the number of new houses sold, because interest rates for mortgages were falling and many consumers were waiting to see how low the rates would go. This large sales drop was accompanied by a sharp rise in the average price of new houses sold.
Which of the following, if true, best explains the sharp rise in the average price of new houses?
(A) Sales of higher-priced houses were unaffected by the sales drop because their purchasers have fewer constraints limiting the total amount they pay.
(B) Labor agreements of builders with construction unions are not due to expire until the next January.
(C) The prices of new houses have been rising slowly over the past three years because there is an increasing shortage of housing.
(D) There was a greater amount of moderate-priced housing available for resale by owners during January than in the preceding three months.
(E) Interest rates for home mortgages are expected to rise sharply later in the year if predictions of increased business activity in general prove to be accurate. 答案是a，题目说卖房子的数量减少了，但是平均价格升高了。c说因为新房子的价格升高了。这样就能解释价格升高的原因了。为什么不可以阿。[em12]作者: topway7 时间: 2004-7-9 08:31
因为贷款利率升了 所以新房的销售量少了但是 新房的平均售价大幅提高了问如何解释? 那么在答题之前就可以运用数学知识大致判断一下:肯定是在所卖的新房中高价房多了.A符合这个判断, C只是说过去三年价格上涨了,不能就此证明今年也涨了,何况C价格上涨的原因是increasing shortage of housing,而题中已经告诉大家人们都在观望,销售量是减少了.
