The diagram illustrates the process of how a water filter is used and constructed to produce clean water.

Overall, the method for constructing a water filter is concluded to have 6 main materials. Which is a tube, sand, charcoal, gravel, pipe, and a small tube to store the processed clean water. After constructing the water filter, than the process of filtering water could begin, and it concluded as 4 main steps that are filtering, removing, cleaning, and transporting.

Before the process starts, individuals need to construct a water filter by firstly connecting the small tube and large tube together with pipe, than inserting gravel around the tube. After that charcoal were inserted in the top of the gravel, and sand are putted in the top of the charcoal. After all of the materials were constructed, we shall continoue to the process of how the water filter filtered the water.

Firstly, impure water that going into filtered process by changing the collor of the water with sand, than it continue to removing process where harmfull bacteria were killed by charcoal antibiotic substance. After removing process, the water than were cleaned through gravel and transported into another tube that store clean water.

Task Response

The report addresses the task by describing the construction and function of the water filter, and it includes an overview. However, there are several inaccuracies and unclear descriptions. For instance, the order of layers is described incorrectly (gravel at the bottom, then charcoal, then sand), and the function of each layer is misrepresented (e.g., sand changing color, charcoal killing bacteria). The report also includes irrelevant details about the number of materials and steps, and the language is often imprecise. To improve, focus on accurately describing the diagram's key features, use clear and concise language, and ensure the overview summarizes the main stages without unnecessary detail.

Coherence & Cohesion

The report has a logical structure with an introduction, an overview, and body paragraphs, but the flow is often disrupted by awkward phrasing and unclear referencing. For example, the overview lists materials and steps in a confusing way, and the body paragraphs mix construction and filtering processes without clear transitions. To improve, use clear topic sentences for each paragraph and ensure each paragraph focuses on a single main idea. Also, use cohesive devices (e.g., 'firstly', 'then', 'after that') more accurately and avoid abrupt shifts between stages.

Lexical Resource

The report uses some appropriate vocabulary related to the process (e.g., 'construct', 'filter', 'transport'), but there are several inaccuracies and limited range. Words like 'collor' (color), 'harmfull' (harmful), 'continoue' (continue), and 'putted' (put) are misspelled or misused. Additionally, phrases like 'charcoal antibiotic substance' are unnatural. To improve, expand your vocabulary for describing processes (e.g., 'undergo', 'pass through', 'eliminate impurities') and ensure correct spelling and word choice. Use more precise terms for the materials and their functions.

Grammatical Range & Accuracy

The report contains numerous grammatical errors that affect clarity. There are issues with subject-verb agreement (e.g., 'charcoal were inserted', 'sand are putted'), incorrect verb forms (e.g., 'putted', 'continoue'), and incomplete sentences (e.g., 'Which is a tube...'). Punctuation is also problematic, with run-on sentences and missing commas. To improve, practice using a variety of sentence structures, ensure subject-verb agreement, and proofread for common errors. Focus on using correct past tense forms and proper punctuation to enhance readability.
