The response to lectures involves a bit of library and internet research. You should choose an issue or point raised in the lecture, find a scientific, peer-reviewed article by doing an online library search. Then do an internet search for another relevant source on that issue or point. You should
briefly summarize each of your research findings and state how they relate to the lecture. You should do this by the deadline and then check back so as to reply to two of the posts of classmates. Discussion of lectures chapter 5-8.
