I was thinking it would be "de" instead of des since the adjective is before the noun.  What am I missing?  Thank you.

In the two optional answers below, why hasn't 'beaucoup' been given as an option to 'nombreuses'?

Why is the plural form of "complimenter" used in this sentence? 

This appeared in a test question on Laura's site.

(If I was rich, I could travel a lot.).

Is this grammatically correct? No!

Shame!!!

One possible translation heer is given as "Est-ce que l'on peut aller prendre un café? "

Is the "le" at all related to the café as direct object?  Could you explain/provide examples of other uses of "l'on" in such contexts?  Merci en avance! 

In the phrase, "...il faut défendre ses opinions", why do the French use 'ses'?  I would have expected 'vos', i.e. it is necessary to defende YOUR opinions.  Is it simply the way the French express this allusion to others?

when is une peinture un tableau?

Hello. Would it make a subtle difference if we use "on doit" instead of "on devrait" in this context? What would be the difference? Thank you.

Would it be an alternative to say:  Ils ont du [accent] leur devoirs avant le diner [accent]" (which I believe translates to  "They must have finished their homework before dinner.")

Can you please explain how these are different?
