Help me out with a question pleaseee 🧍🏻‍♀️

Ok sooo the question is basically that

"regional parties have started to play an important role in Indian politics" comment.

This is supposed to be in the context of 1989 and beyond era but I guess a few examples of previous eras (like 1977 or before that) could also work.

It's a question of 6 marks. I do know a few points but I'm not exactly sure how to write them down?
