Band 7+: You should spend about 20 minutes on this task. The diagram below shows how ethanol fuel is produced from corn. Summarise the information by selecting and reporting the main features and make comparisons where relevant. You should write at least 150 words.

The given diagram illustrates the process of producing ethanol fuel from corn. Overall, there are eight steps in this process, starting with collecting corn from corn trees and ending with transporting and distributing ethanol fuel in several gas stations.

At the beginning of the process, the corns are collected from the corn trees, after which the harvested corns are stored in several warehouses to prevent them from bad conditions. Then, the corns are milled step by step through a machine into a mixture and cooked for 4 hours with adding water. After that, the mixture is fermented in another machine for 48 hours.

The process continues when the mixture is separated into liquid and solid products. The next step of the process is that the liquid product is purified ethanol. At the final stage of the process, the finished ethanol is packaged and supplied to different gas stations for consumption.
