Answer to Question 1

Answer: A

Answer to Question 2

Answer: Atmospheric refraction adds to daylight time. When we see the Sun on the horizon, it is already below it. Refraction makes it appear higher in the sky, and we have about 9 minutes of additional sunlight per day because of atmospheric refraction.
