What is the main reason to do research before a group discussion? to find facts and details to use as evidence to find a topic that is interesting and complex to be able to talk a lot during the conversation to show why a student’s opinion is the only right one

Explanation:

When you're going to assist to a discussion you must talk based on facts and evidence, otherwise you're going to be speculating and that takes you nowhere in the discussion.

In fact, evidence is the main core of discussion. Imagine that a political leader attends to a public discussion and talks about different topics without evidence, he's just a clown to people.
