Written answer form ?

Hello,
I am testing Educator.
I’ve adding Written answers for one lesson but when I test it I can’t see any form for answer to the question.
So, Is it the good way for received students answers and how to do this ?
You can see the problem to http://www.kreaclic.fr/lessons/concevoir-un-site-web/
Thanks for your help and thanks for Educator
