The quiz says: "Lucas a monté la nouvelle armoire de sa soeur: means.
The 2 answers expected were:
1. Lucas assembled his sister's new wardrobe.
2. Lucas took his sister's new wardrobe upstairs.
But the French does not specify the location so the translation can only be "Lucas took his sister's new wardrobe up" - not upstairs. Perhaps it was up a ramp or a hill. Since that translation was not offered surely only the one answer should be allowed.
