Problem:
Some students said they couldn't play the sound files from the web page.
If you are having trouble hearing the sound files when you click the link, it is possible that your audio player is out of date. In this case, you may need to update it. The mp3 files that are on the page for Chapter 3 can be played by many different players, including Windows Media Player and Apple QuickTime. Since most of you use Windows Media Player, I will explain the steps to take to update this audio player.
