Q: Developing cars that run on hydrogen gas can help solve our dependence on what?


Read this paragraph and choose the correct option from the provided answers:

You won’t see this car on the road, at least not yet. It’s a concept car that was developed by a major automaker. Instead of burning gasoline, it runs on hydrogen gas. Using hydrogen for fuel doesn’t produce pollution, and it doesn’t depend on nonrenewable fossil fuels. New technologies like this car may one day help solve our energy resource problems. But even without new technologies such as this, there are many ways we can help solve the problems right now.

 Choices:

- oxygen

- food

- water

- nonrenewable fossil fuels


A:
nonrenewable fossil fuels
