问题 For which of the following years was there an increase over the previous year in the number of existing homes sold, but a decrease in the number of new homes sold?  
In the year shown in which the median price of existing homes sold was closest to the median price of new homes sold, approximately how many million existing homes were sold?
选项 A、1.2
B、1.6
C、2.0
D、2.4
E、2.8
答案B
解析 在图中，旧房销售价格的中数与新房最接近的那一年，大约销售了几百万座旧房?
解：本题的正确答案为(B)。根据房子的中等售价图(Median Price of Homes Sold)可以发现，旧房与新房的中等销售价格在1970年近似相等，该年份销售的旧房数量需根据房子的销售量与年份的关系图(Number of Homes Sold)来确定，由此图可知1970年旧房的销售量约为1.6 million。
