Choose whether it is A.M. or P.M.:
My sister is reading me a bedtime story to prepare me to sleep at night.
The correct answer is P.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 'night'.
We know that the night is the part of each day when the sun has set and it is dark outside. It is the time when most people are sleeping.
So, the correct answer is P.M.
