The only way is to contact an editor and hope that they read your message and send the question back to you before they approve, because once it's approved, it can't be corrected until it's played in the New Question game and someone sends a correction in.
You can find who the category editors are by going to the main category pages. For example, if you click the Humanities link from the home page, you should see the list of Humanities editors underneath the list of list of Humanities subcategories.
