[求助] og11th-34

34 Efforts to equalize the funds available to school districts,a major goal of education reformers and many states in the 1970's , has not significantly reduced the gaps existing between the richest and poorest districts,

此处考虑到Efforts，因此应该选择复数形式have,但是答案选择的D项为have not significantly reduced the gap that  exists。为什么不用existing呢? 记得一般现在时用来表示客观真理，但此处用进行时是不是也对呢？

忍者哥哥，原题的D是 the gap that exists

吓偶一跳，hoho

呵呵，多谢楼上的：）
