Les grands maisons (my answer)

Kwiziq says it's Le grandes maisons however when you look at the examples they say grand is the plural form is grands. Why did they mark my answer as incorrect?

I am so confused! Question: _____________le Louvre

I answered : Qu-est ce que c'est le Louvre. Kwiziq says this is partially right. Their answer" Qu-est ce que le Louvre

When I go to "Explain this" my answer seems to be the correct one given the examples they give but they say not. Can anyone explain this?

bon outil d'apprentissage des langues, mais trucs très malsains

When I see the sentence, She smells good, does it mean she smells good (because she doesn't have a cold and her nose is working normally) or it is because she just took a bath (and she doesn't stink?).  Do both these meanings work for Elle sent bon?

"Can anybody help me?" I'm curious about why this inversion needs "il" after "peut"?  Is the non-inverted question form: Est-ce que quelqu'un peut m'aider?

I have seen that the verb retourner is used with "Y

Nous y retournons demain.

 We go back there tomorrow

"Il n'a pas pu retourner de la guerre.

He couldn't return from the war.

 Can I say

 il n'en a pas pu retourner 

He couldn't return from there

Does it work like that?

Why did it change from "on" to "nous" in the last sentence?  Is it just more common with commands?

Just to be sure. Is it okay if I say, 

« Regardez cette fleur. C’est beau, n’est pas? » ?
