Avoir besoin de test question

Question

The question in the test quiz "Cette année, Michaël ________ perdre du poids" is marked wrong if you enter "doit", it wants "a besoin de".  Whilst this is correct in the context of this lesson, as far as I can see looking at the lesson comparing the use of Devoir and Avoir besoin de, the use of "doit" would also be reasonable.

Sure. But, as you already point out, the lesson is about using the phrase avoir besoin de qqc.

Tran Nhi · Answer

I have the same problem as Ian. Should both answers be accepted in the quiz as I attempted the quiz after reading the "Devoir and Avoir besoin de" lesson, and both are correct answers. I tried to report a problem at the question, and I got a quick reply that "doit" was marked wrong and asked me to come to this thread for further discussion.
