Task Response

The report attempts to address the task by describing the electricity consumption and cost of household devices, but it contains significant inaccuracies and irrelevant information. The data presented (e.g., '10 dollars,' '90 kwh/year') does not match the provided visual description, and the inclusion of 'kwh/year' and 'watts' is not supported by the task or visual. The report also introduces categories like 'luxury items' and 'daily usage items' that are not clearly indicated in the chart. To improve, focus on accurately reporting the given data, making clear comparisons between devices, and avoiding unsupported details. Ensure the response stays relevant to the task requirements.

Coherence & Cohesion

The report attempts to present an overview and some comparisons, but the overall structure is unclear and the message is difficult to follow. The introduction misinterprets the data (e.g., 'usage of electricity... for every watt consumed'), and the body paragraphs lack a logical progression. The conclusion is somewhat repetitive. To improve, focus on a clear, logical structure: start with a general trend, then describe the main features in a systematic order (e.g., from highest to lowest cost), and ensure each paragraph has a clear central idea. Use cohesive devices more effectively to link sentences and ideas.

Lexical Resource

The vocabulary used is basic and often imprecise (e.g., 'usage of electricity', 'luxury items', 'daily usage items'). There are also inaccuracies in describing the data (e.g., 'Spa having pump and heaters' instead of 'pool pump'). To improve, use a wider range of more precise vocabulary related to data description (e.g., 'consumption', 'expenditure', 'appliances', 'significantly higher', 'substantially lower'). Avoid informal or vague terms like 'things' or 'items'.

Grammatical Range & Accuracy

The report contains numerous grammatical errors and awkward phrasing that significantly impede understanding. Examples include subject-verb agreement errors ('Spa... has'), incorrect prepositions ('usage of electricity in different home appliances'), and incomplete or run-on sentences. Punctuation is also inconsistent. To improve, focus on writing clear, grammatically correct sentences. Practice using a variety of sentence structures (simple, compound, complex) and ensure subject-verb agreement and correct tense usage throughout.
