2008 Short Fiction Competition

Sorry if this is mentioned somewhere in the rules and I missed it.

I wanted to know if it is necessary to include the prompt word for word within your story or if it simply has to be about the prompt.

For example does the story need to contain the exact words "A mysterious figure watches from a distance." or can there just be a figure watching from the distance at some point such as "I watched mysteriously from the distance." or some other variety. Thanks.
