People from different cultures have different conventions for answering seemingly innocuous questions like this. Users will become frustrated if when you ask for an email address, for example, if the response box only allows for 20 characters.
See our Guidance notes, page 6, paragraph 2. When filling in your forms people want the information they need there and then. Put yourself in the form users position and think about which questions they might have a problem with. Provide examples of the sorts of answers you are looking for, and where appropriate, provide guidance notes as near as possible to the question they relate to (i.e. in the actual form).
