The above translation is correct. However, the lesson marks it as incorrect and says the correct answer should be "She wants some bleu cheese". Clearly the English spelling is "blue"
Could you give us more info? What platform (computer/phone) are you using and what exercise was it (typing/picking word tiles/listening)?
It is fixed from my perspective. We'll investigate the error if we know where it's coming from.
why is it that the English translation "wishes for" and "wants" is accepted in some cases and not in others?
The verb "vouloir" is directly translated as "want". If you translate with "want" you will have no problems. Any other synonym, and you're relying on whether "wish for" fits the particular meaning of "vouloir" in the sentence and whether they've been added to the database.
I'm trying to remember if I ever saw the 'bleu' translated in the US to 'blue' when referring to the cheese. I always thought it was like 'taco' - a word that stayed true to it's origin.
