French language Q&A Forum

I have tried to figure out why some words in the example sentences are in bold and some are underlined, but I don't get it and I can't find it in FAQ or anything.

In the last sentence I typed "quand ils partent de mon salon !" but "partent de" marked as an error and advised "quittent" or "sortent de". 

Could you please explain why "partent de" cannot be used here as an option ?

For "partir", in the relevant lesson, it is written as: "When used with a place, it will always be followed by a preposition (e.g. I leave from / for  = Je pars de / pour)" Example: Je pars de cette ville.

How do I say there will be sun tomorrow?

Tu es calme into imperitif?

Mes chausseurs ne vont pas ensemble:  _____ est bleu est l'autre jaune-colors may be wrong.  I put l'un which was wrong and l'une was right.  What am I missing here, chausseur is masculine

Why isn't it 'depouillement des votes'?

Why is "celle" the correct answer  to this

 "J'aime ta robe mais je préfère ________ que Laura porte," 

rather than "laquelle"?

Aren't they both pronouns identifying one among others?

This exercise is broken into more audio files than usual. This means that each file is shorter, and this is very helpful as I listen to each section many times, usually just to hear a couple of difficult parts that I’m having trouble understanding. I thought it would be useful to let you have this feedback! :)
