Image for topic: The diagram below shows how ethanol fuel is produced from corn

Our system will evaluate the answer based on this AI-generated description.

The image consists of a circular diagram with eight stages showing the ethanol production process from corn. The stages are numbered from 1 to 8, starting with corn, then moving to storing, milling, cooking with water for 4 hours, fermenting for 48 hours, separating liquid from solid by-product, purifying ethanol for 5 hours, and ending with storing and gas station. Each stage is represented by a line drawing of the respective process or machinery involved.

Given the complexity of the image, the above description may not be entirely accurate.

The process illustrates how fossil fuel called ethanol fuel is made from corn.

Overall, process involved 9 stages, starting with storing the corn and ending with delivering to the gas station. It is also good to measure the vehicles, devices and chemicals used in process with latter taking up the largest proportion.

To start with, process begins with collecting the corn and storing it before milling it where it cleaned from leftovers. Milled corns delivered to the place, where corn cooked 4 hours with water. After cooking completed, it transported to fermenting where it stayed 48 hours. After fermenting completed, remained corn divided by two: liquid and solid by product.

After that, it transported to fabric where corn liquid and solid corn product purified with ethanol 5 hours. After 5 hours of completing the purifying method, it delivered to the store, where it deilevered to gas station using vehicle called truck.

Task Response

The report covers the main stages of the process and follows a logical sequence. However, there are some inaccuracies in the interpretation of the data, such as the claim that chemicals take up the largest proportion, which is not supported by the visual description. Additionally, some phrasing is slightly unclear (e.g., 'it transported to fabric'). To improve, focus on using more precise transitional phrases and ensuring that all observations made are directly supported by the provided diagram.

Coherence & Cohesion

The report follows a logical sequence, following the stages of the diagram from start to finish. However, the progression is hindered by repetitive sentence structures and a lack of sophisticated cohesive devices. The use of 'After... completed' is repetitive. To improve, try using a wider variety of transition signals (e.g., 'Subsequently', 'Following this', 'Once the fermentation stage is concluded') and vary your sentence openings to create a smoother flow.

Lexical Resource

The vocabulary is sufficient to describe the basic steps, but it is quite limited and repetitive. There are several instances of awkward phrasing, such as 'remained corn divided by two' and 'corn liquid and solid corn product purified with ethanol'. Additionally, the term 'fossil fuel' is factually incorrect in the context of ethanol (which is a biofuel), and 'fabric' is likely a misspelling of 'factory'. Aim to use more precise technical verbs (e.g., 'processed', 'separated', 'distilled') and avoid repeating the word 'corn' in every sentence by using synonyms or pronouns.

Grammatical Range & Accuracy

Grammatical errors are frequent and occasionally impede communication. There is a consistent issue with the omission of articles (e.g., 'process begins' instead of 'the process begins') and the incorrect use of passive voice (e.g., 'it transported' instead of 'it is transported'). Since this is a process diagram, the passive voice is essential for describing how things are done. Work on mastering the present simple passive tense and ensuring that subject-verb agreement is maintained throughout the report.
