version 5 by Michael Callaghan
When we answer a question, the answer is processed by a rulebook. By adding our own rules in the game, we can tailor the Questions extension to provide the functionality that we require.
Each type of question has its own rulebook. These are:
Number questions: The number question rules.
Real number questions: The real number question rules.
Menu questions: The menu question rules.
Yes/No questions: The yes/no question rules.
Gender questions: The gender questions rules.
Text questions: The text question rules.
