Answer 1

I'm unable to see images or diagrams. However, I can help you understand how to determine the correct relative positions of the Sun, Moon, and Earth based on the phase of the Moon you observed.

1. New Moon: The Moon is between the Earth and the Sun, and the illuminated side is facing away from Earth.
2. Waxing Crescent: The Moon is slightly east of the Sun (from Earth's perspective), with a sliver of light visible.
3. First Quarter: The Moon is at a right angle to the line between the Earth and the Sun. Half of the Moon is illuminated.
4. Waxing Gibbous: The Moon is still moving away from the Sun, but more than half is illuminated.
5. Full Moon: The Earth is between the Moon and the Sun, with the entire face of the Moon illuminated.
6. Waning Gibbous: The Moon is past full, moving towards the last quarter, but still more than half is lit.
7. Last Quarter: Like the first quarter but on the opposite side, half of the Moon is illuminated.
8. Waning Crescent: The Moon approaches a new phase, with a small sliver of illumination left.

If you can describe the phase of the Moon that the students observed, I can help you determine which diagram (A, B, C, or D) is correct.
