Today I have a test for you. Don't worry, this involves nothing painful like a poke with a needle by a student nurse or reciting the Gettysburg Address while nasty children throw rotten tomatoes at you.
All that I'm asking is for you to pick just one of the following examples that you like best, and a short explanation why.
Now remember, I want to see your report on my desk first thing in the morning. If you do well on your homework, I may dismiss you for an early recess. But if you score poorly, you may be kept after school (along with those nasty kids who were caught tossing the tomatoes).
After all, I only said this wasn't painful... I didn't say there weren't any consequences. :D
