Instead of saying, 'nous avons reste des predateurs', why couldn't we write, 'nous avons demure des predauteurs'?
I understand that the lesson is focusing on one skill but it would seem that if the student got the concept correct but used a different word that was correct, it should be accepted. (unless of course demurer should not have been used in this lesson instead of rester).
Thank you! I love Kwiziq (and I had sent an email previously about how some of the feedback from the lessons could be enhanced).
