What is one expaple of your own of two parties in a dispute that a judge and jury might decide. Your scenario must illustrate a "fact" (something the jury believed and found to have happened or that exists) and it must illustrate a legal question the judge decided. Your legal issue cannot be about letting a witness testify.  Other legal issues can be: whether a piece of evidence can be shown to the jury; whether a witness knows enough about something scientific to be considered an expert; whether the law the judge told the jury to follow was the correct law to follow.
