Explanation:

1b: At new - moon, the Moon is between the Earth and the Sun. Sunlight does reach the Moon, but the side of the Moon facing the Earth is not illuminated. The far - side of the Moon is illuminated.
1c: At the first - quarter phase, half of the Moon is illuminated by the Sun. This is because the Sun, Earth, and Moon form a right - angle, and the Sun's rays illuminate half of the Moon's surface.
1d: At the first - quarter phase, we see half of the sunlit part of the Moon from Earth. This is due to the geometric arrangement of the Sun, Earth, and Moon at this phase.

Question 1c: Half of the Moon is illuminated by the Sun at the first - quarter phase.
Question 1d: We see half of the sunlit part of the Moon from Earth at the first - quarter phase.
