Sorry again. :)

Bonjour Max !

That's an excellent question :)
Here it's a question of pronunciation:
- indeed if you pronounce [tooss] (like in the example), then "tous" = all [of the people/of them]

- but if you pronounced [too] with a mute h, then the "tous" would go with "vos devoirs"and would mean = "all your homework".

Have a look at our related lesson:

I hope that's helpful!
Bonne journée !
