Why should goals be set for a group discussion? to limit who participates in the discussion to ensure that there are no discussion rules to form an opinion before the discussion to establish a purpose for the discussion

The reason why goals should be set up for a group discussion is “to establish a purpose for the discussion” If no clear goals or objectives are provided to the group, then the discussion might address topics or ideas that were not intended. Also, if you provide specific goals prior to the discussion, you make sure the answers and opinions given by the group are focused on what you want to achieve at the end of the discussion.

Goals do not limit the participation of specific people in the discussion so the fisrt option is incorrect.

Also, by setting up goals you are also introducing certain rules that should be accomplished so option 2 is also incorrect.

And finally, option 3 is also incorrect as the objective of setting up goals is not to form an opinion before the discussion.
