Which of the following describes the situation in the US properly?

参考解析：

细节理解题。根据文章第二段第三、四句“High-skilled occupations increasingly clustered in cities, while low-skilled service jobs have become more plentiful outside of urban centers. At the same time, wages for mid-skilled jobs like manufacturing and office work equalized between cities and rural areas — workers in these jobs can no longer get much of a pay bump by moving into town”可知，高技能职业越来越多地聚集在城市，而低技能的服务业工作更多地出现在市中心以外地区。与此同时，制造业和办公室工作等中等技能工作的工资在城乡之间趋于均等——从事这些工作的工人再也无法通过移入城市获得大幅涨薪。因此A项（城市中的低技能工作少于农村地区）符合文意。故选A。
