我認為was produced是可以省略的....當然...我也認為which was改成同位語應該也沒啥錯...硬要挑毛病應該是因為前面有完成式...為避免混淆故列出過去式
但是選項E) 基本上我是不會選的..companies who ...公司不是人....
另外要是有be動詞的形容詞子句...我基本上也不會選...做到目前為止沒有一題對....因為wordy...隨便舉個例
The girl who is beautiful is a lesbian.
The beautiful girl is a lesbian.
參考一下吧~~~

"硬要挑毛病應該是因為前面有完成式...為避免混淆故列出過去式 "
不知是指哪裏?

不過看了你的解說了解多了
company who果真是不能選
seed companies who have been motivated by profit 也不好
這邊的完成式是不是也不對?
