For those of you who like to make notes as you study, this lesson incorporates an answer/comment form for your personal use. Click on a  button in the lesson to display the corresponding section of the form in this frame. You can copy/paste a text or enter your own response.

You need to enter your email address below to have your comments returned to you. When you are done for the session, press the [Send] button. The form will be returned immediately formatted as a web page and shortly as an email message. Print the returned web page or the email message.  Those who study the lesson in several sessions may find it convenient to combine the email messages from each session into one document, editing out the extraneous material with a word processor or text editor.
