1. My friend and I were confused about question #3. Couldn't a parsec be used to measure the distance of a star or the light travel time, since they are related? Isn't measuring in parsecs interchangeable with measuring in light-years? Could you clarify?
2. Do stars, planets, the sun and the moon all move from east to west across the sky? Can you explain question 25?
Thank you for your help.
