RES 710 Week 3 Discussion

Students need to contribute SIX substantive posts in this discussion for attendance per week based on academic policies. The substantive posts can be any combination of responses and replies.

Please choose six questions to respond from the followings. Please respond to one question a day for 6 days or two questions a day every other day. Do not post all 6 messages in one day because the system will record your attendance as one day per week only, and you will be auto-dropped from the class accidentally.
