French language Q&A Forum

Just wondering why these exercises aren't marked automatically.   I think the whole thing would flow much better if we could go straight from one section to the next.

Is it not acceptable here to say 'Cherchez-vous'?

this combination of verb tenses in a si claus/result statemnet  seems at odds with what I've learned about them.

why not "si tu avais besoin d'aide, je serais ravie de t'aider" as a second condtional   or

"si tu as besoin d'aide, je serai ravie de t'aider" as a first condtional?

If you don't know the person, how can you use te; si vous ne connaissez pas cette personne, comment peut-on utiliser te?

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 ,

In the second sentence, the conversation has "lui" although it is hard to distinguish "lui" from "leur" with the speaker's intonation.  For the remainder of the conversation, the conversation has "leur" when referring to the recipient(s) of the gift.  While I can get the difference after listening for multiple times, I still find it strange that the two are not consistent.
