2) It is waning.
3) There is not enough information given to answer this.

Answer 1

The Moon is highest in the sky at 9:00 pm and it is waxing.

Step-by-step explanation:

The Moon is highest in the sky at 9:00 pm, and it is at the gibbous phase. The gibbous phase occurs during the two weeks following the full moon when the Moon is more than half illuminated. As the Moon progresses from the first quarter phase to the gibbous phase, it goes through a waxing phase, meaning it is getting larger and more illuminated. Therefore, the answer is 1) It is waxing.
