This lesson says to use the gerund to express "while" AND "by".  But all your examples use "while"...small thing but it would help the learning process if the examples would demonstrate both usages!

Merci

Bonjour,

Can someone please explain why the following is marked incorrect?  I'm having the same issue that Michael appeared to have in December but it's still outstanding for me.

"Qu'est-ce que c'est La Sorbonne" is scored incorrect, and  the accepted answer is:

"Qu'est-ce que La Sorbonne", but according to the lesson:

If you want to ask what something is by name, simply add the name of the thing after c'est quoi or qu'est-ce que c'est. These are not the most elegant questions, but probably the most commonly used.

Merci
