Je pense

Why "Mon fils travaille (present tense) comme promeneur de chiens depuis quelques semaines" for has been working? and not "Mon fils a été travaillant comme promeneur de chiens quelques semaines"?

"on aurait dit un savage" translates to it looked like a savage, but I'm unsure of the rule for that. Is there a lesson on this? 

I've heard this as a song title, but all of the examples above are sentences with auxiliary verbs, so is this correct French?

The question was “ tell your friends, don’t sit down!” Shouldn’t we use the tu form not the vous form in this case?

Dans le texte, j'ai remarqué que "Liban" est parfois précédé de "Le", et parfois de La. Pouriez-vous clarifier cela? SVP. 

Why is the future perfect used in this sentence: "Mais personne mieux que Claude Nougaro n'aura incarné..."?

Would present tense not work here?

In the following example, I am struggling to understand why we must use la and not lui? To me, it sounds like the sentence requires an indirect object pronoun, because the question "What" is not answered in response to the "must", which is the verb in this sentence. I use the "what" test to determine if there is a direct object in the sentence. With this sentence, should I consider "what must they warn" as my question, or "what must they do". Apologies if my line of thought is completely skewed but it seems to work in most cases. 

Does Julie know? We must warn her ,

Why is it "Tarte au Maroilles" and not "Tarte aux Maroilles"?
