(A) a gradualreversion to the raising of agricultural staples
(B) that a gradualreversion back will feature the raising of agricultural staples
(C) a gradualreversion back to the raising of agricultural staples again
(D) a gradualreversion to raise agricultural staples（A）
(E) a gradualreversion into the raising of agricultural staples
我想问下下为什么D不对呢？

划线部分的 to the raising of... 的 to 与前面的 toward increasing consumption......中的 toward用法相同，是介词+n. 表示向n.的回归趋势。同时与前面的对比形成很好的对称。
D中to 为动词不定式结构，撇开对称和语义不谈，仅从语法上，用to do来修饰a reversion ，在我理解的范围内，不符合idiomatic，也没有forsee sth to do 的结构。事实上只要这里用to do , 语义就完全变了。

哦，谢谢，说道语义的话是这样

不过你看错啦，前面是increased ~~~不过还是对称
