It's Friday, 4 July 2014. Most of us in the U.S. are off today. For those of you who are working today, do you really feel like working? Well then, take a break and test your test knowledge with a few questions. Answers appear on the last page.
In the three previous test quizzes -- see last page for links -- I asked for readers to submit their own questions. The questions here are courtesy of David Ashton. Thank you, David.
And now, David's quiz questions.
