Accepted Answer

Hi G,
I have managed to find the exercise and have corrected accordingly. 
I don't think you can pin the Fill-in-the blanks to the Q&A so you couldn't do it, sorry!
Anyway, it is done now.
Bonne continuation!

Hi G,
Yes, you are correct, although in speech it is dropped. If you send me the link I can add it.

How do I do that? There is nothing on the page to "report" and no Q&A forum attached to that particular test. The only link I can provide is the URL:
