PREP1-Q1

To meet the rapidly rising market demand for fish and seafood, suppliers are growing fish twice as fast as their natural growth rate, cutting their feed allotment by nearly half and raising them on special diets.

(A) their natural growth rate, cutting their feed allotment

(B) their natural growth rate, their feed allotment cut

(C) growing them naturally, cutting their feed allotment

(D) they grow naturally, cutting their feed allotment

(E) they grow naturally, with their feed allotment cut

答案是D，但是我选的是C。D中的they不是有指代不清的嫌疑嘛，既可以指代suppliers，又可以指代fish。
而且根据平行对称的原则，“suppliers are growing fish twice as fast as” 后面不是应该也是growing嘛？
望各路大侠的指教，实在搞不懂这题
先在此谢谢各位啦~

夜幕如斯

这题有陷阱 大大的坏
D项they grow naturally表达的意思是供应商养殖鱼的生长速度 比鱼自然生长速度快两倍

C项growing them naturally是平行，但是意思就变成供应商人工养殖鱼的生长速度 比自然养殖鱼的生长速度快两倍
逻辑意思改变了 而且有点awkward

哦，经过你的一番解释，我恍然大悟，GMAT的陷阱真多。。。
