French language Q&A Forum

In another lesson (sorry I don't know the name of the lesson, since I encounter them randomly), you specifically state that this sentence is not correct: 

"Elle me rappelle de Paula."  How is that different from "Elle se rappelle de ce garçon", which is given in this lesson as correct? It seems that "de" is not allowed in the first sentence but it is allowed in the second sentence. 

What is the possessive pronoun for "on"? Is there a fixed one or does it depend on the situation i.e. whether "on" is used as a replacement for vous or nous? Thank you!

Why use "on" to say " we" drank, we took etc. 

Could somebody tell me the meaning of 'les santons' in this dictée?  The sentence is; j'ai laissé la petite jouer avec les santons

Thank you

My question is about a quiz question in this unit: "J'ai décidé d'apprendre à jouer du piano cette année." How do you know it's "apprendre *à* jouer" instead of "apprendre *de* jouer," for example. I think that French verbs differ in this respect, but I haven't seen any systematic explanation of it, and I don't even know how to talk about it in a way that could make internet search productive. Do you have any teaching materials about this, or can you help me to understand it better? Thanks in advance.

I did a simple quiz.  One of the problems was to translate "We have a cat"  - I used the  nous avons... option.  It was wrong stating "On a..." is the correct answer.  How can one tell if an informal response, or the commonly spoken one is the correct choice out of context?  It sees to me, both answers are equally correct.  What am I missing?

Merci
