La vs. le

Bonjour Claus !

In French, le, la, l' (it) and les (them) are used to replace objects.

The choice between le and la is depending on the gender of the prementioned object.

In this case, you were not given any clue as to what the object gender was (what was sent), therefore both "Bernard la lui envoie (e.g. la lettre)" or "Bernard le lui envoie (e.g. le colis) were possible answers.

We could have offered either, but we went with la.

I hope that's helpful.
À bientôt !

Hi Aurélie My understanding is that in French the default is masculine. If defined male - le/il/ils would apply If defined female - la/elle / elles would apply If mixed/not specified use male. In this case for the question of Bernard sends it to her, wouldn't it be more logical to expect the 'le' response or both le and la in the test?
