11. In the most common procedure for harvesting forage crops such as alfalfa, as much as 20 percent of the leaf and small-stem material, which is the most nutritious of all the parts of the plant, shattered and fell to the ground.
(A) which is the most nutritious of all the parts of the plant, shattered and fell
(B) the most nutritious of all parts of the plant, shatter and fall
(C) the parts of the plant which were most nutritious, will shatter and fall
(D) the most nutritious parts of the plant, shatters and falls
(E) parts of the plant which are the most nutritious, have shattered and fallen

Key是D，我选的是B。不明白为什么用shatters and falls。主语是哪个呢？
这个句子结构怎么分析，请哪位大侠指点一下啊，多谢！

主要是20% of n.的单复数问题，知道跟n.一致即可。
由后面的material知道是单数，所以谓语动词也用单数。
In ...(介词引导状语从句)..., ... 20% of ..(主语).., the most ...(主语同位语)..., shatters and falls ...

PS 同学，这里是逻辑区～～

不好意思，贴错地方了

多谢啦！句子结构很清楚了。
我看到which后面是is，后面的谓语也应该用单数的。
另外问一下，如果A,B都不可数，A and B做主语，谓语应该用单数还是复数呢？谢谢！
