The apostrophe certainly doesn't belong there, thanks.

I've changed the typo (though a database refresh is required before it will - hopefully - show up).

I am concerned about the classification of this test as 'elementary' level, though. There seems to be quite a lot of vocabulary required of an 'elementary learner' in order to comprehend these answers.
