can someone explain to me quickly the questions asked and how to answer them?
Teece,
You'll find a brief description of the kinds of questions asked during a polygraph "test" on the AntiPolygraph.org Frequently Asked Questions list (http://antipolygraph.org/faq.shtml).
For a more detailed explanation of the trickery behind these fraudulent "tests," and to learn how to "pass" them, see Chapters 3 & 4 of The Lie Behind the Lie Detector (http://antipolygraph.org/pubs.shtml).
