The same problem, I think, as with La Sorbonne issue below

Question

Why is "Qu'est-ce
que c'est une baguette" marked as being wrong for "What is a baguette?" when
the notes say that "Qu'est-ce que c'est un stylo" is correct for
"What is a pen?"

Accepted Answer

Hi Adrienne,
You can express 'what is something? in four different ways -
Qu'est-ce que la Sorbonne? 
Qu'est-ce que c'est la Sorbonne ?
Qu'est-ce que c'est que la Sorbonne?
C'est quoi la Sorbonne? 
The last two would be used in every day speech. 
If your correct answer wasn't accepted it is probably a problem in the specific quiz, will let Aurélie know...

Answer

I’m wondering that also, Adrienne. Surely that is also correct? That is what is stated in the lesson. I would normally add the “que”, but I’m not sure it’s absolutely necessary

Answer

Thanks Carrie and Cecile.  There is clearly a small glitch in the quiz program.  Adrienne
