According to some economists, the July decrease in unemployment so that it was the lowest in two years suggests that the gradual improvement in the job market is continuing.
so that it was the lowest in two years
so that it was the lowest two-year rate
to what would be the lowest in two years
to a two-year low level
to the lowest level in two years
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
D选项错在哪里呢？
two-year low level和the lowest level in two years是两个意思。前者的意思是一个两年的低等级，后者的意思是，两年内的最低值。
所以说，选E是为了保持原句意思吗？
划线前面是说七月的失业率下降，如果是D选项，意思是到了一个两年到低水平，那么前后到比较期间不一样。如果是用D选项，前面可以是2014-2015 decrease in unemployment。
D的多错误可以参照Ron的解释：

谢谢~ D选项理解为“一个两年的低水平”；E是“两年内的最低水平”。
