Each student may respond with strongly favor or strongly oppose to at most five questions. Because Jeffs students are very understanding, each student is happy if he or she prevails in just one of his or her strong policy preferences. Either describe a polynomial time algorithm for setting course policy to maximize the number of happy students or show that the problem is NPhard. 2.
