Question

question 3 not yet answered marked out of 1.00 flag question bio - alcohol is used primarily: a. as a blend with traditional petrodiesel. b. by itself. c. as a blend with liquefied natural gas. d. as a blend with gasoline.

Explanation:

Bio - alcohol, such as ethanol, is commonly used as a blend with gasoline. This is because it can enhance octane ratings and reduce emissions. For example, E10 (a blend of 10% ethanol and 90% gasoline) is widely used in many regions. Blending with petrodiesel (biodiesel is a different bio - fuel blend with petrodiesel), using it by itself (not practical due to engine compatibility in most cases without modification), or blending with liquefied natural gas (not a common practice for bio - alcohol) are less typical primary uses.

Answer:

d. as a blend with gasoline.
