Read this passage about the Energy Crisis. Then answer the questions.

The world depends on non-renewable resources like oil and coal. The term "non-renewable" means that one day, the world will run out of that resource. As the world's resources run out, the cost for energy will rise. This is bad for everyone. If people can't afford coal for their power plants, they can't power their homes. If people can't buy gas for their cars, they can't drive to work. If energy is not affordable, people can't use it. This is the energy crisis. Some people feel that the way out is to drill and dig for more non-renewable resources. However, others believe that alternative energy sources, such as nuclear power, might offer a solution.

What is a benefit of nuclear power over other non-renewables?

A. Uranium is a lot easier to mine than coal or oil.
B. Nuclear reactors don't expel pollution into the air.
C. Nuclear reactors don't produce a waste byproduct.
D. Nuclear power is relatively cheap.

E. I don't know this yet.
