A type of alcohol made from plants is called ethanol. Plants such as corn and sugarcane which are used in cereals and breads are used to make ethanol. When ethanol is burned, it is a clean source of energy because the products are carbon dioxide and water. Therefore, if ethanol is mixed with gasoline to use for fuel, the harmful waste products will be reduced.
In the 1970s, many people from Brazil drove cars that were equipped to use an ethanol-gasoline mixture. When used as an alternative fuel, the ethanol-gasoline mixture conserved the limited supply of gasoline that was available at that time.

A. Because it increases biodiversity
B. Because it decreases air pollution *
C. Because it reduces
