Scott, if you want a bonus answer to display added information, you can't put the added information anywhere in the third column because that column needs to consist solely of "ee" (without the quotes) so that line can be recognized as a bonus answer. However, you can put the added information in the center column along with the answer (as a text explanation, worded however you like), then put a slash followed by the bonus answer all by itself. Typing the bonus answer will cause the text explanation to appear. See the image below for an example, in a hypothetical quiz about listing the monarchies in Asia:
I assume you're doing this in a Classic quiz, and make sure the box for "Bonus/Hidden answers become wrong answers" is NOT checked on the Options page.
