Put the verb in brackets into the Present Simple or the Present Continuous. Millie (understand) Maths?

The correct answer is: Does Millie understand Maths? Explanation: The question is asking about Millie's understanding of maths in general, not at this specific moment. Therefore, the Present Simple tense is more appropriate than the Present Continuous. Since 'Millie' is a singular subject, we use 'Does' to form the question. So, the correct question is 'Does Millie understand Maths?'
