Task Achievement / Task Response — Band 4.0
The response is severely under-length, containing only 100 words against the required minimum of 150 words. This significantly limits the student's ability to cover all parts of the prompt adequately. While the student attempts to summarise the diagram, the text miscounts the number of steps, stating there are 6 steps when the diagram clearly depicts 9 numbered steps. Additionally, important intermediate processes such as filtering, softening with chemicals, and pressing are omitted or glossed over. The overview is weak and uninformative. Due to the incomplete coverage, under-length penalty, and factual inaccuracies regarding the process stages, this falls under Band 4.0.
Coherence and Cohesion — Band 4.5
The text suffers from poor paragraphing and structural cohesion. The entire main body of the response is written as a single, massive run-on sentence connected by comma splices and repetitive transitional phrases like 'afterwards', 'moving ahead', and 'after that'. There is no clear division into distinct paragraphs or logical stages of the manufacturing process. Pronoun referencing and cohesive devices are mechanical and overused, creating a breathless reading experience. Although the chronological order of the process is somewhat maintained, the lack of appropriate discourse markers and standard paragraphing results in a Band 4.5 performance.
Lexical Resource — Band 5.0
The vocabulary used is very basic and repetitive. Words like 'plant', 'harvest', 'strips', 'liquid', 'yarn', and 'fabric' are lifted directly from the prompt. The student attempts a few process-related terms such as 'pulp', 'spinned' (incorrect form), and 'weaved', but the range is extremely limited. There are noticeable word formation errors, such as 'cutted' instead of 'cut', and spelling mistakes like 'elliminated'. The vocabulary is barely adequate to communicate the basic sequence of events, aligning with the descriptors for Band 5.0.
Grammatical Range and Accuracy — Band 4.5
The grammatical structure of the essay is heavily compromised by comma splices, run-on sentences, and a complete absence of proper punctuation over long stretches. Almost the entire body paragraph is stitched together with commas instead of full stops or appropriate subordinate clauses. There are persistent morphological errors, such as 'is cutted' and 'is spinned', alongside active/passive confusion. The structural range is restricted entirely to simple clauses chained together. Frequent errors that impede smooth reading place this criterion at Band 4.5.
