Corinne is playing in a golf tournament representing her school. while playing in a foursome that includes her best friend, sheila, corinne notices that sheila took 5 shots to finish the 16th, 17th, and 18th holes but put a 4 on her scorecard for all three holes. how should corinne handle this situation?

post a blog on sheila’s website accusing her of cheating
say nothing at all and mind her own business
tell the tournament official what she witnessed
wait until she gets home and tell her parents what she saw
