Image for topic: The diagram below shows how drinking water is made using solar power.

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

The image displays a diagram illustrating a system for purifying water with the use of solar power. It features a solar panel that captures sunlight and is connected to a converter transforming solar energy into electricity. Electricity powers a pump located in an underground well, which pumps water up to a water tank situated on a wooden platform. The water tank is connected to a water filter, which purifies the water for drinking. The clean water is then dispensed through a tap into a moveable container. No numerical data points, percentages, or any quantitative information are provided in the image.

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

The diagram gives information about the process making a drinkable water with help solar panels.

Overall, the process starts with solar panels, which takes power from sunlight, and ends with a moveable container, where drinkable water is collected. The process continue in five steps, using complex equipments.

Looking at the information in more detail, first of all, solar panels catch the sunlight to provide power and it is sent to a compact converter box, where the obtained heat is converted to electricity. The next step is to pump underground water from a deep well. The received electricity is used to pump out water to a water tank, which is located on a platform made of wood. There, the water is gone through a filter to remove any dirt. Once the water has been purified, drinking water is sent to a moveable container, which is regulated by a tap before moving into it.

Task Response

The report effectively covers all stages of the process described in the diagram, from the collection of sunlight to the collection of purified water. The overview is clear and provides a good summary of the start and end points. To improve, ensure better grammatical accuracy regarding subject-verb agreement (e.g., 'process continues' instead of 'process continue') and refine the use of articles. The description of the technical steps is logical and follows a clear sequence.

Coherence & Cohesion

The report follows a logical progression, moving from the source of energy to the final collection of water. The use of sequencing words like 'first of all', 'the next step', and 'once' helps the reader follow the process. However, the cohesion could be improved by using more varied cohesive devices and ensuring that the relationship between sentences is smoother. Some transitions feel a bit mechanical.

Lexical Resource

The vocabulary is adequate for describing the process, using terms like 'purified', 'converter', and 'moveable container'. However, there are some inaccuracies in word choice and collocation, such as 'making a drinkable water' (water is uncountable) and 'complex equipments' (equipment is uncountable). Aim to use more precise academic verbs and avoid pluralizing uncountable nouns to improve your score.

Grammatical Range & Accuracy

There are several grammatical errors that impact the flow of the report. Specifically, there are issues with subject-verb agreement (e.g., 'solar panels, which takes' should be 'take'; 'the process continue' should be 'continues') and awkward phrasing (e.g., 'the water is gone through a filter'). While the report uses a mix of simple and complex structures, the frequency of these errors prevents a higher score. Focus on mastering subject-verb agreement and the correct use of passive voice for process descriptions.
