You've already got some answers (the mirror one is probably what I would have done), but I just wanted to share an approach Justin, one of our developers, thought up that is very slick. Essentially you use CSS to conditionally display things only for specific questions.
The first step would be to give a unique class to the conditional text using something like a span tag. Let's assume we put the following into a question called Q1:
Answer 1 <span class="SpecialDisplay">Text of interest goes here</span>
Without anything from you, the text will just display as Answer 1 Text of interest goes here.
However, we can leverage the way SSI Web builds questions to quickly tell the browser not to display something on a certain page. For example, if I have Q1 and Q2, and I want to use the same list but not display additional text in Q2, I could leverage a div tag ID and my own span tag and do the following:
What that does is tell the browser that if something has both the q2_div ID and a class of SpecialDisplay, don't display it. The result is that on Q1 I would see "Answer 1 Text of interest goes here" but in Q2 I would just see "Answer 1."
