I used énorme for huge and it got the redline with only 'immense' indicated as correct: a response here from Cécile some time ago stated she used 'énorme' when running through the exercise also. 

I frequently come across responses where it would seem either ensuite or puis can be used, but mostly only one is accepted, and I always seem to choose the "unaccepted" word ! (That is why my gambling is limited) Again, a previous response from Cécile in another exercise indicated they are essentially interchangeable, as Larousse also indicates.

Can both énorme and ensuite be added ?
