Now we're going to try something completely different.
Below is a list of problems.
Under each of the problems is a list of options for you to select from.
Choose what you think is the correct answer, and you'll be told whether or not your
selection was correct.
Next to each problem is a link taking you to the section that problem uses.
Click on the link if you want to go back for a review.
Unlike the exercises, prior to now, you'll only have one chance to choose
the correct answer
