Image for topic: The diagram shows how electricity is produced from coal. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

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

The image shows a 9-stage process of making electricity from coal: (1) a Coal Supply System uses a conveyor to move coal to (2) a Pulverizer. The pulverized coal is then burned in (3) a Boiler, creating steam and ash. Exhaust gas passes through (4) a Dust Collection System and exits via a Stack. The steam powers (5) a Turbine, which is connected to (6) a Generator that produces electricity. The steam then enters (7) a Condenser, where it's cooled back into water by (8) a Cooling System. The ash from the boiler is collected by (9) an Ash System for disposal. Finally, the electricity goes to a Substation/Transformer and is distributed through a transmission tower.

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

The diagram demonstrates the process by which electricity is produced from coal.

In summary, the manufacturing process involves 9 stages, beginning from a system that supplies the fossil fuel and finishing with the disposal through the ash system.

Firstly, the initial resource is pulverised, being crushed to smaller particles. Subsequently, it is boiled in high temperatures, and went through a system that collects its dust. Following this, coal passes into a turbine. Motored by a turbine, generator transforms the fuel into electricity. The product is next transported from the turbine to condenser. Afterwards, it flows and has its temperature lowered in a cooling system. The final phase is in the ash system. The produced electricity power is transported to it and went to disposal, where the cycle is finished.

Task Response

The report covers the main stages of electricity production from coal, but there's room for improvement in clarity and organization. Consider structuring the description more logically, perhaps grouping related stages together. Also, focus on using more precise language to describe the transformations and processes involved at each stage. For example, instead of 'Motored by a turbine, generator transforms the fuel into electricity,' you could say 'The turbine powers a generator, which converts mechanical energy into electricity.' Finally, ensure that all stages are mentioned and their relationships are clearly articulated. The report falls short of the required 150 words.

Coherence & Cohesion

The report provides a general overview of the process but lacks clear connections between the stages. The flow of information could be improved by using more cohesive devices to link the steps in a logical sequence. Paragraphing is present but could be used more effectively to group related stages of the process. For example, the description of the initial stages (pulverizing, boiling, dust collection) could be grouped into one paragraph.

Lexical Resource

The report uses some appropriate vocabulary related to the process, such as 'pulverised,' 'turbine,' 'generator,' and 'condenser.' However, the range of vocabulary could be expanded to provide a more detailed and precise description of each stage. Consider using synonyms and more specific terms to enhance the clarity and sophistication of the language.

Grammatical Range & Accuracy

The report contains grammatical errors and phrasing issues that affect clarity. For example, 'went through a system' should be 'goes through a system,' and 'Motored by a turbine, generator transforms the fuel into electricity' is awkward and could be rephrased as 'The turbine powers a generator, which transforms the energy into electricity.' Correcting these errors and improving sentence structure would enhance the overall accuracy and readability of the report.
