A. understand that managing the moon landing while the lunar module had 30 seconds left of fuel required intense concentration.

Answer:
Ethanol lowers the amount of harmful carbon dioxide gases released into the air by burning fossil fuels like gasoline.
Explanation:
"Ethanol fuel" is considered a<em> renewable fuel </em>that is derived from "biomass."
A biomass is an<u> organic matter</u> such as <em>agricultural products (corn), wastes, woods, garbage, alcohol fuels, etc. </em>So, this means that <em>ethanol is not only made from distilled, fermented corn.</em> Such type of ethanol is known as <u>"corn ethanol."</u>
Ethanol, compared to gasoline, <u>can lower the amount of harmful gases released into the air</u>. For example, when ethanol is combined with gasoline, the emission results to more regulated pollutants. When ethanol is used as a fuel for vehicles, the carbon dioxide it produces is counteracted or offset by the crops (corn crops, for example) that are needed for its production.
Thus, the amount of harmful carbon dioxide gas is being reduced.
