I use these five options when i am writing a questionnaire type of quiz on a form for a customer. the five options are:

Agree | Strongly | Agree | Neither | Disagree | Strongly | Disagree

or you can have them backwards

Strongly Disagree | Disagree | Neither | Agree | Strongly Agree

as you can see the person can put this on a form to ask the user for some input using very simple HTML code.

hope this helps you
