why not he climbed down the magic beanstalk?

Question

"In another example I read that Jacques est descendu de l'arbre means Jack climbed down the tree. So why cannot Jacques est descendu du haricot magique mean Jack climbed down the magic bean as well as Jack got off the magic beanstalk?" In the quiz I took, I was told it was wrong.

Answer

"Jacques est descendu de l'arbre means Jack climbed down the tree." 
Really the English translation should read "Jack climbed down from the tree"
This point is the translation of "de" above.
I suspect this is why you are being marked wrong.
Hope this helps.

Answer

I’ve just had the same problem. In English, 'got off ' and 'climbed down' the beanstalk mean the same. I don’t understand why this is not accepted by Kwizik.
