Final answer:
To make a negative question in French about brushing teeth in the morning, use the words 'ne' and 'pas' surrounding the verb 'te brosses'.
Step-by-step explanation:
In French, to make negative sentences, we use the word 'ne' before the verb and 'pas' after the verb. So to make a negative question asking if someone brushes their teeth in the morning, you would say 'Est-ce que tu ne te brosses pas les dents le matin?' The word 'ne' and 'pas' surround the verb 'te brosses' which means 'brush' and 'les dents' means 'the teeth'.
