Why couldn't I say "as voulu" for "why did I want a dog?

If I wanted to say, "I misunderstood," would any one of the following be acceptable?

Je me suis mépris. 

J'ai mal compris.

Je me suis trompé.

Why is it 'cote d'Azure' but 'cote atlantique'?

Which is correct je ne veux pas or que ne je voulais pas

Why does the last sentence use the impersonal construction, "Pourquoi se priver" instead of "nous priver"? 

Also, I translated "namely" as "en l'occurrence" but that wasn't one of the accepted answers (only "nommément" and "à savoir"). Is there a difference?

I am not sure why it is not que chaque esclave, or que tous les esclaves...?

the lesson says "Adjectives modified by adverbs with 2 or more syllables"
And the lesson made an example:
"Compare these examples with the following counter-example containing a one-syllable adverb:
un très joli manteau
a very pretty coat"

Based on the information the lesson provided, I assumed "une histoire très intéressante" wouldn't be right.
I saw other questions on this, but none really explained the rule.

Is it because besides having one-syllable adverb, the adjective also have to be one of those that are put before the verb?
