In an effort to shorten the time span and cut the costs needed to grow full size beef stock, many ranchers substitute cornmeal and ground bones for their cattle's regular diet, branded by them to become generic-grade beef.

A.for their cattle's regular diet, branded by them
B.for the regular diet of their cattle which have been branded
C.for the regular diet of their cattle, having been branded
D.in place of their cattle's regular diet, for those of them branded
E.in place of the regular diet of their cattle to have been branded by them

答案B
本题按照首三词排除DE which应该有逗号排除B C的having看着不爽排除 选了A
求教各位大牛

TerraceHo

meaning：爲了縮短生長週期和降低養育全牛的成本，很多ranchers用cornmeal和gournd bones代替他們的牛的正常diet。
問題是對於後面brand修飾成份的理解。

brand表示加商標於，銘刻於。那麼代入原句意思應該是，在他們身上加商標說他們是質量好的牛肉（翻譯巨噁心，見諒哈><）

A項，branded修飾diet，diet和brand的意思not make sense。
B項，利用which從句直接修飾cattle，注意cattle是plural，所以which後面用have。
C項，having been branded做的是verb modifier，修飾substitute，同時也要與subject make sense。
但是，如果這樣理解的話，就變成ranchers have been branded。not make sense.

另外，排除的時候最好有一些確定性的理由，例如concision，主動優於被動等最好都是到最後確定性的理由都用完都無法排除的時候才使用啦

了解 翻译的很给力 句意是王道 刚开始还是没有领会brand的意思
