The first decision for most tenants living in a building undergoing being converted to cooperative ownership is if to sign a no-buy pledge with the other tenants。

答案：(E) conversion to cooperative ownership is whether to sign

OG解释：The process of being converted does not need to be shown since undergoing already contains the idea of process

也就是说being和undergoing这里是重复的？这里being是be的进行时？

如果将undergoing去掉。那这里的being是不是就正确了呢？

谢谢 。
