Choose whether it is A.M. or P.M.:
I am brushing my teeth before school.
The correct answer is A.M.
- A.M. = Ante meridiem: Before noon
- P.M. = Post meridiem: After noon
- Noon (or midday) is 12 o'clock in the daytime, as opposed to midnight.
The keyword here is 'brushing teeth', and 'before school'.
We know that this activity is a sure happening in the morning.
So, the correct answer is A.M.
