Explanation:

• Question 47:
• The Moon rotates on its axis and revolves around the Earth. When the Moon's period of rotation (the time it takes to spin once on its axis) is equal to its period of revolution (the time it takes to orbit the Earth), the same side of the Moon always faces the Earth. This is called synchronous rotation.
• Question 48:
• A total solar eclipse occurs when the Moon passes between the Sun and the Earth, blocking the Sun's light. For a solar eclipse to occur, it must be a new - moon phase. In April 2024, the new - moon was on April 8.

Answer:

1. D. revolution equal to its period of rotation
