Additional possibility for the translation of 'fulfilling'

Question

In the translation of "... or by starting a new fulfilling hobby.", I chose 'gratifiant’ for ’fulfilling’.  It was not accepted.   Was it overlooked or is there some distinction that I don’t understand ?  Thanks, in advance.  BTW, I thought this exercise was easier than the B1 Giving up Smoking.

Accepted Answer

Bonjour Frank,
Thank you for your comment! You are correct that "gratifiant" is an alternative to "fulfilling". It has now been added to the correct options.
Also, it is possible that sometimes a B1 exercise will look easier than a B2 because of the grammar skills you might have already mastered or simply because the B2 exercise is on the very low end of the scope. However, I will discuss this with my other colleagues.
I hope this is helpful.
Bonne journée !
