GWD-24-3求解

Although the discount stores in Goreville’s central
shopping district are expected to close within five years as a result
of competition from a SpendLess discount department store that just opened,
those locations will not stay vacant空的 for long.  In the five years since the opening of
Colson’s, a nondiscount department store, a new store has opened at the
location of every store in the shopping district that closed because it could
not compete with Colson’s. 总是不能理解这最后一句到底讲的是什么，哪位Nn讲解一下，谢谢
