The diagram gives detailed information about a simple system that makes drinkable water through undrinkable water.

Overall, It’s evident that, the system includes various process, starting with put dirty water into plastic barrel, continuing with mix with ingredients such as sand, charcoal and gravel, ending with drinkable water by storage drum tank.

Looking at the details, the process begins when dirty water is poured to plastic barrel tank. After putting, the dirty water is mixed with diversity of crucial ingredients namely, sand, charcoal and also gravel.

Then mixed liquids are sent to the next stage where facilitated process is applied. After liquid turned into the tank, the mixed liquid cleaned. Before the final stage where people are consumed, the tank is modified the water from undrinkable to drinkable water.

Task Response

The report addresses the task by describing the water filtration system, but it contains some inaccuracies and unclear phrasing. The overview mentions mixing ingredients, which is not accurate; the layers filter the water rather than mix. The description of the process is somewhat repetitive and lacks clarity in places. To improve, focus on accurately describing the sequential flow of water through the layers and the collection in the storage drum. Use precise vocabulary and avoid vague terms like 'facilitated process'. The report falls short of the required 150 words.

Coherence & Cohesion

The report has a basic structure but lacks clear progression and logical flow. Paragraphing is not effectively managed, and the use of cohesive devices is limited and sometimes inaccurate. To improve, organize the description into clear paragraphs: one for the overall process and one for detailed steps. Use a range of linking words (e.g., 'firstly', 'subsequently', 'finally') to guide the reader smoothly through the stages.

Lexical Resource

The vocabulary is limited and repetitive, with some inappropriate word choices (e.g., 'makes drinkable water through undrinkable water', 'mix with diversity of crucial ingredients'). To improve, use a wider range of precise terms related to filtration (e.g., 'filtration system', 'layers', 'purification', 'contaminants'). Avoid informal phrases and ensure word forms are correct (e.g., 'undrinkable' instead of 'through undrinkable').

Grammatical Range & Accuracy

The report contains frequent grammatical errors, including incorrect verb forms ('makes drinkable water through'), missing articles ('a plastic barrel'), and awkward sentence structures ('After putting, the dirty water is mixed'). Punctuation is inconsistent. To improve, practice using a variety of sentence structures (simple, compound, complex) accurately. Review basic grammar rules, especially subject-verb agreement and the use of articles. Proofread carefully to eliminate errors.
