a ，e 的which 错了

c  不平行

d 的话单纯从语法上来讲 过的去（个人感觉）  ，however  stabilziing 不应该是 to increase 的伴随动作， 应该是 和to  increase 平行的

b 的 an ex。。。做同位语  修饰 six b cubic a day


是不是这样的， 我开始选的d 错了

OG对D项的解释：
D Stabilizing is an incorrect verb form; it
should be an infinitive to parallel to increase;
the subsequent phrase is awkward and
confusing because it is not clear what noun
allowing is supposed to modify.

不太明白黑体的部分哈，个人认为allowing在这里做状语，逻辑主语是yield，前面stabilizing也是如此，之所以错是因为两个句末的状语很奇怪……
不知道这样相对不对啊？？

照OG的说法，allowing还能修饰谁啊？？

恳请NN们解答！！
