The diagram below illustrates the process of producing a biofuel called Ethanol from corn.

The production begins by gathering the raw material, which is corn, and storing the corn in order to proceed to the next step. The vegetable is then milled and cooked for four hours, encorporating water in the process. Additionally, the cooked corn-water mixture is to be fermented for approximately 48 hours, to obtain a more concentrated fuel.

After fermenting, it undergoes a procedure called separating, where the compound is transformed into a liquid fuel called ethanol. The substance was initially in solid state, but after dividing its contents and deriving the by-product, it transforms into a liquid state. The production will then proceed with purifying the fuel for 5 hours, to achieve the most concentrated results. Finally, the ethanol is stored and ready to be tranported to its designated destination for usage.

In summary, producing ethanol fuel from corn is a tedious process which requires a meticulous amount of preparation, starting from its raw form and resulting in an important source of energy which aids in our daily lives.

Task Response

The report adequately covers the main stages of ethanol production from corn, presenting a clear overview of the process. However, there's room for improvement in terms of detail and comparative language. To enhance the response, consider including more specific details about each stage, such as the purpose of milling and fermenting, and the destination of the solid by-product. Also, incorporating comparative language to highlight the transformations at each stage would further elevate the response.

Coherence & Cohesion

The report is generally well-organized and easy to follow. The progression of the ethanol production process is clearly described. However, the use of cohesive devices could be improved to enhance the flow between sentences and paragraphs. For instance, using more varied transition words and phrases would make the connections between ideas smoother. The final paragraph is a bit too general; try to summarize the key stages or highlight a specific comparison rather than just stating it's a tedious process.

Lexical Resource

The report demonstrates a good range of vocabulary related to the process description. Terms like 'milled,' 'fermented,' 'separating,' and 'purifying' are used appropriately. However, there's room to incorporate more precise or technical vocabulary to elevate the description. For example, instead of 'vegetable,' using 'corn' consistently would be more accurate. Also, consider using synonyms or more specific terms to describe the processes involved to showcase a wider lexical range.

Grammatical Range & Accuracy

The report demonstrates a good command of grammar with only minor errors. The sentence structures are varied, and the tense usage is generally accurate. However, pay attention to subject-verb agreement and article usage to eliminate minor errors. For example, 'encorporating' should be 'incorporating'. Reviewing the report for these small errors would further enhance its grammatical accuracy.
