Why is "ce dont on a envie" (in the fourth sentence) not correct here? For that matter, why is "ce qu'on a envie" correct? The expression is "avoir envie de", isn't it?  What am I missing here?

Also: why must the past tense in English ("didn't pay", "were encouraged") necessarily be translated as the present tense ("ne paye pas", "est encouragé") in French?

And finally, why  is it incorrect to use "souhaiter" rather than "aimer" in the last sentence?

Why is it de l’argent which I thought meant some money. The lesson wrote: either money or a gift. So why was soit d’argent wrong? Thanks. 

As I understand, a normally silent consonant at the end of a word should be pronounced if the following word starts with a vowel.

 Could you please explain why this does not happen with the S and O in the expression 'au caS Où

Thank you
