The diagram illustrates the process of how corn become ethanol fuel.

Overall , it can be seen that this process contain plenty of steps such as harvesting , milling , cooking , fermenting , separating , purifying , storing and distributing.

Corn will be havested in the field then be storing and ready to be millied. In the next step , the millied corn added with some water will be cooked for approximately four hours and be fermented for two days.

Apart from that , the remain product will be separated into liquid which will be kept and the solid – by product will be removed. Once that is done, the liquid will purified ethanol for five hours to become ethanol fuel . Ultimately , the products will be storing and ready to be transported and distributed to gas station.

Task Response

The report adequately describes the process of ethanol production from corn, covering the main stages. However, there's room for improvement in terms of detail and precision. To enhance the response, consider including more specific information about the quantities, temperatures, or other relevant parameters involved in each stage. Also, ensure that the sequence of steps is clearly and accurately presented, avoiding any ambiguity or potential misinterpretations. Pay attention to grammar and sentence structure for improved clarity. The report falls short of the required 150 words.

Coherence & Cohesion

The report provides a general overview and follows the process sequentially. However, the organization could be improved with clearer paragraphing to separate distinct stages of the process. Transitions between steps could also be smoother to enhance the flow of information. For example, using phrases like 'Following this' or 'Subsequently' can help connect the steps more logically.

Lexical Resource

The report uses vocabulary relevant to the process, such as 'harvesting,' 'milling,' 'fermenting,' and 'purifying.' However, the range of vocabulary could be expanded to provide a more detailed and nuanced description. Consider using synonyms or more specific terms to describe the actions and equipment involved. For instance, instead of just 'separating,' you could describe the method of separation if known.

Grammatical Range & Accuracy

The report contains grammatical errors that affect clarity. There are issues with verb tense consistency ('Corn will be havested'), subject-verb agreement, and article usage. Sentence structure is relatively simple, and there's room to incorporate a wider range of grammatical structures to express the information more effectively. For example, using passive voice where appropriate ('the corn is milled') or complex sentences to combine steps could improve the grammatical range.
