The diagram illustrates the process in which raw corn is used to produce ethanol fuel.

Overall, there are three main stages: collecting raw corns for storing, convert these into ethanol fuel that can be used, and delivering them to supermarkets for sales. The second stage is the most intensive, with five steps, which is double the others stages.

In detail, raw corns will be harvested and stored in suitable places for later use in the first stage. What follows is the second stage, beginning with milling these corns into powder, to which water is then added. The mixture from this addition is subsequently cooked for four hours before fermenting for 48 hours. After two days in a fermentation process, the resulting oil liquid is separated from the solid by-product of the previous step and then purified for 5 hours to ensure the ethanol oil is clean and is safe to use. In the final stage, final products will be stored for some time before being transported to supermarkets to sell to the customers.

This is a very poor practice example.. Ethanol is an alcohol-based alternative fuel that is added to gasoline for trucks and cars.

We do not eat or drink gasoline, do we? Drinking pure ethanol can be deadly. ) for sales. (wrong form I think you just copied this from another essay!)

Oh my god, thank you so much; this was a real test on 18/1/2020 in my country, and I think if I took the test on that day, I would fail Emotion: sad

Can I ask you a few more questions?

AlpheccaStarscorns (wrong form)

What is the correct form of this word? Is it right if I use “corn” instead?

walk gray 259What is the correct form of this word? Is it right if I use “corn” instead?

Corn (the food) and the crop is non-count. The part that you eat are the kernels of corn. What is left over (you throw away) is the corn cob.


Corns are hard knots of skin that grow on people's feet.

Much obliged for your explanation. Now I understand.
