Task Achievement / Task Response — Band 4.5
The student attempts to summarise the diagram showing the process of manufacturing fabric from bamboo, but the response falls short of the minimum 150-word requirement, containing only 138 words. While the writer outlines several steps in the process, the information is heavily lifted from the prompt's labels rather than paraphrased effectively (e.g., "plant bamboo plants (Spring)"). Furthermore, the overview is extremely basic and the conclusion is abrupt and unclear ("at the end fabric was ready to use"). Due to the under-length penalty and limited independent development of the process features, this performance corresponds to a band 4.5.
Coherence and Cohesion — Band 4.0
The text lacks proper paragraphing, with most sentences grouped together awkwardly, compounded by an irrelevant introductory note about an aging population that appears to belong to a different essay. Cohesive devices are used mechanically and repetitively, such as the excessive use of "and then after that" and "to commence with, firstly". The logical progression of the process is difficult to follow in the middle section due to fragmented sentences and poor referencing (e.g., "After that, after the crush strips to separate long fibres from liquid"). Progression is hindered, leading to a band 4.0 score.
Lexical Resource — Band 4.0
Vocabulary is extremely limited and largely dependent on copying the prompt directly (e.g., "plant bamboo plants", "harvest", "soften fibres"). There are noticeable word choice errors and incorrect word forms, such as "fabrie to bamboo bamboo tree" and "amino oxide" instead of amine oxide. The attempt to use less common vocabulary results in unnatural collocations like "make the spin to make yarn". Communication is strained in places due to these lexical inaccuracies, placing this response at band 4.0.
Grammatical Range and Accuracy — Band 4.0
The submission displays a very limited range of grammatical structures. Most sentences are incomplete, poorly constructed, or contain severe structural errors (e.g., "The diagram below illustrate..." and "In seventh step, make the spin to make yarn with the of spin to produce weave to make fabric"). Subject-verb agreement, prepositions, and clause structures are handled incorrectly throughout. Errors are frequent and severely impede understanding, warranting a band 4.0.
