Explanation:

• Question 7: When an object (like the Sun) is farther away, it appears smaller and dimmer due to the inverse - square law of light (the intensity of light decreases with the square of the distance).
• Question 8: "Apparent" means something that seems or appears to be a certain way, not necessarily the true or exact nature.
• Question 9: During the day, the Sun's bright light scatters in the Earth's atmosphere, making the sky bright. Stars are much fainter than the bright sky, so we can't see most of them.

Answer:

1. A. The Sun would look smaller and dimmer.
2. B. Seeming or appearing to be.
3. C. The Sun's bright light makes the sky too bright to see them.
