This is , I think, a technical question, but I don't know where to post it - perhaps you could pass it on....
In this exercise, every time I have written an apostrophe - "Je l'ai enfin fait", "J'ai obtenu", "J'ai décidé d'agir", J'ai démandé....qu'eux" etc, the marking has flagged this up as an error, as if I have somehow typed "the wrong sort of apostrophe". This has never happened before - I wonder if it is some kind of glitch that has developed with the new marking system - but I'm at a loss to work out what I am supposed to be doing wrong here, and what I could possibly do any differently !
