The flowchart presents how ethanol fuel is made from corn.

Overall, the production of ethanol fuel involves storing and milling the corn, cooking it with water, fermenting, separating the liquid and solid by-products, purifying the liquid ethanol, and storing and transporting it. The process consists of several simple stages from raw material to a final product.

It starts with storing and milling the corn, then cooking it with water for four hours. Once it is cooked, it is then being fermented for 48 hours and separated into a solid byproduct or a liquid. Liquid is then being purified into ethanol for five hours, stored, and finally transformed.

Producing ethanol fuel from corn is a long process. Fermenting is the longest step in making ethanol fuel from corn. It needs 48 hours, whilst cooking the corn with water only takes 4 hours. We can also see that in the end the ethanol fuel is transported to a final destination.

Task Response

The report covers the requirements of the task by outlining the main stages of ethanol production from corn. However, there are some omissions, such as not mentioning all the steps in the correct order and missing some details about the separation of by-products. To improve, ensure all stages are included and accurately sequenced, and provide more specific details about each step.

Coherence & Cohesion

The report is generally well-organized with a clear overview and a logical progression through the stages of ethanol production. However, the connection between some sentences could be smoother to enhance the flow. For example, in the third paragraph, consider using transition words or phrases to better link the steps of cooking, fermenting, and purifying. Paragraphing is adequate, but ensure each paragraph has a distinct focus to improve coherence further.

Lexical Resource

The report demonstrates a good range of vocabulary related to the process description. Terms like 'milling,' 'fermenting,' 'by-products,' and 'purifying' are used appropriately. To enhance the lexical resource, consider incorporating more specific vocabulary related to industrial processes or fuel production. For instance, instead of 'separated into a solid byproduct or a liquid,' you could use more precise terms to describe the separation process or the types of byproducts.

Grammatical Range & Accuracy

The report demonstrates a reasonable command of grammar, with mostly accurate sentence structures. However, there are a few instances where grammatical accuracy could be improved. For example, 'Liquid is then being purified' could be more simply stated as 'The liquid is then purified.' Focus on maintaining consistent verb tenses and ensuring subject-verb agreement throughout the report. While the range of structures is adequate, consider incorporating more complex sentence structures where appropriate to showcase greater grammatical flexibility.
