1. How does corn turn into ethanol?
◯ Corn is heated up to make sugar
◯ Corn is cooked into sugar, which turns into ethanol over time
◯ Corn is what can go into cars to make fuel
◯ Corn uses lots of water
Using corn for biofuel or biodiesel is better than oil in many ways. It is cleaner when being made, doesn’t pollute the earth, and helps stop bad things going into the environment. It can also be cheaper than regular oil, though the process of creating biofuel is more complex.
2. Why is biofuel a good choice for someone to put into their car?
◯ Biofuel is better for the environment
◯ Biofuel is easier to find
◯ Biofuel lasts longer
◯ Biofuel can be made more easily than regular oil
There are a few problems with using corn for biofuel. One problem is that farmers will grow corn for cars instead of using their land to produce corn crops that will then be sold and distributed in markets for people to eat. This means that there might be less food available for people to find and buy, causing a shortage of corn.
3. How can corn for biofuel be bad for a country to grow?
◯ Biofuel is bad for the environment
◯ Biofuel means growing corn for fuel and not for food
◯ Biofuel will not make a country money
◯ Biofuel will hurt people that use it
The correct answer is:
◯ Biofuel means growing corn for fuel and not for food
