The given image illustrates the process of formation of ethanol fuel from corn.

This procedure is carried out in eight different steps, starting from storing where corn is collected and stored. Next the corn is forwarded to milling stage where corn is converted into flour and sent for cooking, which take 4 hours and it is the stage where water is added into corn flour. Moving forward, this mixture is forwarded for fermenting that consume 45 hours of the whole procedure. After fermenting, seperation take place where solid – by product is seperated from liquid. Liquid is sent for purifying and it is the step where ethanol is produced and forwarded for storing and then transported to different fuel stations for usage.

In conclusion, this whole procedure have 8 total steps and each have its own value and consume different time that help to produce ethanol from corn and then it is finally transported to public.

Task Response

The report adequately covers the main stages of ethanol production from corn, presenting a generally clear overview of the process. However, there are some inaccuracies in the time taken for certain steps (e.g., cooking and fermenting), and the description could benefit from more precise language and detail. To improve, focus on accurately representing the information provided in the diagram and using more specific vocabulary related to the process.

Coherence & Cohesion

The report presents the information in a generally logical sequence, following the stages of ethanol production. However, the flow could be improved with more precise transitions between steps. The introduction and conclusion are basic and could offer a more insightful overview and summary, respectively. Consider using more varied cohesive devices to enhance the connection between sentences and paragraphs.

Lexical Resource

The vocabulary is adequate for describing the process, but there's room for improvement in using more specific and technical terms related to fuel production. For instance, instead of 'converted into flour,' you could use 'milled into a fine powder.' Varying your word choice can make the description more engaging and demonstrate a broader lexical range.

Grammatical Range & Accuracy

The report contains grammatical errors that affect clarity. For example, 'seperation take place' should be 'separation takes place,' and 'consume 45 hours of the whole procedure' could be rephrased for better accuracy. Focus on subject-verb agreement, correct tense usage, and accurate preposition usage to improve grammatical accuracy. Also, vary sentence structures to demonstrate a wider range.
