Question

Research into nuclear fusion will likely require a large investment of time and money before it might be used as an energy source.
Which statement best describes the benefits that would make the investment worthwhile?
Fusion requires a large amount of energy and occurs in stars.
Fusion produces large amounts of energy, and the fuel is found on Earth.
Fusion produces no radioactive waste, and the fuel is plentiful.
Fusion requires little energy to begin and would continue through a chain reaction.

Answer 1

I think it is C

Hope this helps :)

Answer 2

The statement that best describes the benefits of nuclear fusion is "Fusion produces large amounts of energy, and the fuel is found on Earth.". Fusion is a more practical source of energy if ever scientists find a way to contain its production of extremely high energies. Although it produces nuclear waste like fission, its waste is much less radioactive. Also, its source, hydrogen, is very abundant on Earth.
