The Garbage Project Demonstrated Which of the Following About America's

The Garbage Project demonstrated which of the following about America's landfills?

A) Thanks to the recent public focus on recycling, only about 1% of our landfills' space is taken up by paper products.
B) Disposable diapers, plastic bottles, and large appliances together make up roughly 50% of a landfill's volume.
C) Very little in our landfills actually biodegrades; after 20 years, from 1/3 to 1/2 of all organic materials are still recognizable.
D) Organic material tends to biodegrade rapidly in our landfills, leaving abundant room for other types of garbage; contrary to popular opinion, space for landfills around large cities is in no danger of running out.
