Answer:


Question: Ethanol is a type of alcohol made from plants. Sugarcane and corn, which are both used in foods such as cereals and breads, are used to make ethanol. Burning ethanol provides a clean source of energy because the products of ethanol are water and carbon dioxide. Therefore, mixing ethanol with gasoline reduces harmful waste products. In the 1970s, many Brazilians drove cars with engines that used an ethanol gasoline mixture. This alternative fuel conserved the limited supply of gasoline available at that time. In the 1990s, gasoline became cheaper than ethanol, and Brazilians returned to driving more gasoline-fueled cars. Recently, Brazilians started driving more cars that use an ethanol-gasoline mixture. Ethanol is a good alternative fuel because it

Choices:
A. reduces air pollution
B. increases biodiversity
C. reduces sound pollution
D. increases ozone emissions
