Answer to Question 1

Answer: C

Answer to Question 2

Answer: Granite is predominantly composed of quartz and feldspar minerals. These minerals (especially quartz) are very resistant to weathering. Conversely, marble is metamorphosed limestone. Even though marble is hard and durable as a building stone it does succumb to weathering. With time, marble may dissolve from the conglomerate.
