the art of oratory

I have a course named the art of oratory and Im supposed to participate in a discussion talking about  ( How have you used contrast in real life to persuade someone?

Were you doing it on purpose?

How have YOU been persuaded to change your mind by someone else?)

I need someone very good in writing and can get me the full mark out of this discussion , its just one page long but needs to have strong content .. I will be rating our deal according to the grade I got from this so please only expert writers can contact me. one last thing , the attached file is the rubric of this discussion.

Thanks
