Which fuel is made from sugars in plants, blended with gasoline, and helps decrease the amount of oil used?

• A. Ethanol
• B. Biodiesel
• C. Methanol
• D. Propane

Answer: (A)

Ethanol is produced by fermenting the sugars found in plants such as corn or sugarcane. When blended with gasoline, ethanol displaces some petroleum use because it’s a renewable fuel produced domestically, helping to reduce overall oil consumption. It also often acts as an oxygenate, promoting cleaner, more complete combustion and typically improving octane ratings. Biodiesel is made from fats and oils and is used in diesel engines, not blended into gasoline. Methanol can be made from various sources but isn’t the plant-sugar fuel highlighted here, and propane is a hydrocarbon fossil fuel, not derived from plant sugars.
