A landscaper is shopping for landscaping materials. She wants to use materials through which water flows easily.Which two materials should she choose?

Water flows easily through materials with large, connected spaces between particles. Gravel and loosely packed soil have spaces that let water pass through, so the correct choice is gravel and loosely packed soil. Clay has very tiny spaces and slows water flow, while solid granite also does not let water pass through easily.
