A new genetically engineered papaya was produced not by seed companies who have been

motivated by profit, which was the case with most genetically modified crops previously approved

for commercial use, but university and United States Department of Agriculture researchers who

allowed growers to use it free of charge.

顶一下再问，这里which引导非限制定语从句为什么不对，为什么要用as,谢谢！

这是一个结构 叫做 as be the case，多出现在比较的考点和同位语中。
case 是一个概念 表示 情况 状况。意思就是在这样的状况下。
该用法非常灵活，但是能适应的意思很多，大部分我见过的出现的题都是正确答案，但是主要还是考 “在这样的状况下”这样一种意思和前面出现的东西做对比或者解释.

乱草花儿

第二问的话，我这样理解 你看which前面的词，是seedcompanies。用which的话意思是seedcompanies as the case 逻辑明显不对。题目的意思是seedcompanies 不盈利 这件事 as the case。。。。而不是company本身是个case。

非常感谢！
所以这里的as是固定用法，不能被which代替，对么？
