When should a sub-ordinate clause begin with "which" and when does begin with "that".
Frequently one sees both the options in the answers. Is there a general rule for choosing one over the other?
Not sure if this has been discussed before. But any pointers would be appreaciated.
This may help a little bit:

But key to learn and spot correct usage is practice.
