Answer to Question 1

Answer: B

Answer to Question 2

Answer: Rainwater falling through the air becomes slightly acidic from chemical reactions with natural carbon dioxide in the air. When this slightly acidic rainwater comes in contact with limestone, the acidic water partially dissolves the rock. For caves and caverns to form, time is needed.
