Note to instructors: Please do not post
these study guides on the Internet where anyone may access them. I choose to
give my students study guides without the answers so they can actually do the
work themselves. However, there are so many schools that have study guides
with the answers posted for easy access my students do not have to look hard
to get out of doing the work themselves. Please delete the answers before
posting the study guides for public access. Thank you!
