How do you know when to use tu and when to use vous?

Why "des murs d'escalade" instead of "de murs d'escalade"?  Note "beaucoup d'obstacles." 

I saw this sentence "Ils ont envie que nous leur donnions notre avis" - does envie here mean 'to want'?

 I’m confused. The lesson states:

“To express lacking [something], you use:

As you're literally saying I lack of [something], you never use partitive articles (du, de l', de la, des) here; i.e., Je manque du sucre.”           

So why not “Je manque de sucre?” The answer directly contradicts the Green highlighted guidance.

Hi,

Is "de" a partitive article by itself? That is, without being used as "du/de la/de l'"? I ask because of the following example

J'apprends le francais. Et moi est un debutant. Alors, Je cherches deux mots cet/ce. 

Why was "préférerais" marked wrong when it is what I believe to be the conditional, i.e. second "e" has an acute accent not a grave as you has said.

How does an adverb derive its masculin or feminine form? The adjective derives it's gender from the noun it is describing, but when the adjective is turned into an adverb, where does the gender come from?

 My instinct was to put a 'de' in front of 'differents' in this sentence. Can I do it?
