Question 2
The Andromeda Galaxy is faintly visible to the naked eye in the constellation Andromeda. Suppose instead it were located in the same direction in space as the center of the Milky Way Galaxy (but still at its current distance).
How would it appear to the eye in that case? A) We could not see it at all.
B) It would look about the same, but would be in the constellation Sagittarius instead of Andromeda.
C) It would be much brighter, because it would be illuminated by the many stars in the center of our galaxy.
