I asked about this previously and I am still confused.
I did a quiz before and it asked how you would ask "what is this" or something to that effect. And it didn't accept "quelle est..." as the correct answer.
The answer I had received is that quelle needs to be followed by a noun. However, previously, my French teachers would say questions like "Quelle est la date?", so I was very confused. Is that phrase incorrect?
Furthermore, I was doing another quiz and got this question:
Quel est le nom ___ restaurant ?
And I was confused why you could ask "what is the name of the restaurant" and use "quel est" and not "qu'est-ce que c'est" or "c'est quoi".
Basically, I'm not understanding if/when you can use "quel est.." or "quelle est..".
Thank you!
