Bonjour,

I found this sentence on wordreference when I checked the word profondeur: 

Ce gouffre a trente mètres de profondeur.

Is it correct??

Merci

Please help for the following : 

What are the differences between these two sentences

1) Il habite à dix minutes de Marseille. 

2) Il habite à 10 min de Marseille. 

My answer was the number one, but the Kwiziq marked it wrong. 

Thank you!

Could anyone please tell me if there are any rules on if and when you can/cannot replace inanimate nouns with subject pronouns? I read the lesson c'est versus il est/elle est and thought you use c'est with nouns while il/elle est is used with adjectives. 

But I have encountered situations where the writer/speaker uses il/elle est with a noun.

For example, if you are referring to (or pointing at) "une lettre", can you say "Elle est une lettre"? Or can you only say "C'est une lettre."?

Or, if you are referring to "une conversation", can you say "Elle va bien" or can you only say "Ça va bien."? 

Thank you for any clarification. 

I wrote "Notre Salade aux Trois Fromages est [...] et assez copieuse" which was marked as incorrect. Looking at Le Robert, copieux is given as a synonym of consistant so I'm wondering why?

Does copieux mean more that the dish is physically large (ie a lot of food) whereas consistant just means it's filling but doesn't given any indication to the size of the meal?

What is the 1st conjugation for?
