E. The percentage of households with an annual income of $80,000 is higher in S than in M city

我们可以假设S城中没有＞80K的人，因为全部都是60K＜S＜80K的人，但M城却有一个＞80K的，而这个假设并不与原文冲突的

我以为原文中，the percentage of households with an annual income of  $60,000 or more 　＝　the percentage of households with an annual income of more than $60,000
