The diagram shows how ethanol fuel is produced from corn. It explains the process step by step, starting from corn and ending with the transportation of ethanol.

First of all, the corn is stored in a special place. After that, it is milled into smaller pieces. This makes the corn easier to process. Then the milled corn is cooked for four hours. During this stage, water is added to the corn. Cooking is an important step because it prepares the mixture for the next stage.

Next, the cooked mixture is fermented for 48 hours. This means it is left for two days so that ethanol can be formed. After fermentation, the mixture is separated into two different parts. One part is a solid by-product, which is removed. The other part is liquid and continues in the process.

After that, the liquid is purified for five hours. This step is done to make clean ethanol fuel. Finally, the ethanol is stored and then transported to different places where it can be used.

Task Response

The report covers the main stages of ethanol production from corn, presenting a clear and logical summary of the process. To improve, focus on incorporating more comparative language to highlight key differences in time duration or process types. Also, try to use more precise language and avoid overly simplistic phrasing to enhance the overall sophistication of the response.

Coherence & Cohesion

The report presents a clear and logical progression of the ethanol production process. Paragraphing is generally well-managed, with each paragraph focusing on a distinct stage. To enhance coherence, consider using more varied cohesive devices to link ideas within and between paragraphs. For example, instead of repeatedly starting sentences with "After that," explore alternatives like "Subsequently," "Following this," or more specific transitional phrases that indicate the relationship between steps.

Lexical Resource

The report demonstrates a satisfactory range of vocabulary suitable for describing the process. However, the language is somewhat basic and could benefit from more sophisticated word choices. For instance, instead of "special place," consider using "storage facility" or "silo." Similarly, replacing "removed" with "extracted" or "separated" could add more precision. Aim to incorporate more technical or specialized vocabulary related to fuel production to elevate the lexical quality. Boost vocabulary complexity to elevate the overall score.

Grammatical Range & Accuracy

The report exhibits a strong command of grammar with virtually no errors. The sentence structures are accurate and appropriate for the task. To further enhance the grammatical range, consider incorporating more complex sentence structures, such as using subordinate clauses or varied sentence beginnings, to add nuance and sophistication to the writing. However, the current level of accuracy is commendable.
