Questions and Answers

We're heard the howls of rage from students, and made the answer checker slightly more forgiving than it was previously. It should now accept:

Spelled out numbers - 'Three' as a synonym for '3', etc, and vice versa.
True/False/Yes/No - 'T'/'F'/'Y'/'N' are now automatically accepted as shorter forms.
'The' - so 'lungs' and 'the lungs' are now synonymous answers.

That's in addition to what it accepted before - answers of 'Coca Cola', 'coca cola', 'cocacola' and so forth should all still be acceptable matches for 'Coca-Cola'. But if you want it to accept 'Coke' - that's down to you and your questions!
