OG11-34 中 a major goal of...修饰什么

adai

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.
    

(A) has not significantly reduced the gaps existing

(B) has not been significant in reducing the gap that exists

(C) has not made a significant reduction in the gap that exists

(D) have not significantly reduced the gap that exists

(E) have not been significant in a reduction of the gaps existing

前面主语是efforts, a major goal是同位语吗，好像前面没有合适的名词可以修饰，最合理的修饰对象是不定式“to equalize the funds available to school districts".这样的修饰感觉有些怪，谁能解释一下，谢谢了
