Over the next few years, increasing demands on the Chattahoochee River, which flows into the Apalachicola River, could alter the saline content of Apalachicola Bay, which would rob the oysters there of their flavor, and to make them decrease in size, less distinctive, and less in demand.

C and rob the oysters there of their flavor, making them decrease in size, 分析该选项
D robbing the oysters there of their flavor and making them smaller, 分析该选项
E robbing the oysters there of their flavor, and making them decrease in size, 分析该选项

正确答案: D
想问DE选项。robbing在这里的施动者应该是increase demand吧？ 但是感觉逻辑上应该是increase demand 改变了content这整件事robbing了而不是increase demand robbing了？

comma + robbing 就是修饰前面的subject 和 Verb，这里robbing是 alter 的result，所以不必在意谁是施动者这种事情
