Task Achievement / Task Response — Band 4.0
The response is severely under-length, containing only 71 words compared to the minimum requirement of 250 words. Because of this extreme brevity, the task is only addressed minimally and the ideas are severely under-developed, cutting off abruptly in the second paragraph ('and they can'). While the writer attempts to introduce a position agreeing with the prompt and mentions a relevant example regarding healthcare, the lack of completion and development prevents any substantial fulfillment of the task. Consequently, this falls firmly within the lower-band descriptors, specifically Band 4.0, due to the minimal and truncated nature of the response.
Coherence and Cohesion — Band 5.0
The text begins with a clear introduction and attempts a logical sequence by introducing a general statement followed by reasons in the second paragraph. However, because the text stops abruptly after only a few sentences, it is difficult to fully assess overall progression and paragraphing structure. The limited cohesive devices used, such as 'First is that', are rather mechanical and basic. Paragraphing is disjointed due to the incomplete nature of the second paragraph. Based on what is actually produced, the writing shows some attempt at organisation but lacks clear overall progression, warranting a Band 5.0.
Lexical Resource — Band 5.0
The student uses a very limited and repetitive vocabulary range, such as repeating 'important' and 'science' multiple times in the opening sentences. There are notable word choice and collocation errors, such as 'improve individuals lifestyle' instead of 'improve individuals' lifestyles' and 'make convenient people's life' instead of 'make people's lives more convenient'. However, the vocabulary is minimally adequate to convey a basic meaning ('vaccines and antibiotics'). These limitations and noticeable errors place the lexical resource at a Band 5.0 level.
Grammatical Range and Accuracy — Band 4.0
The response displays a very limited range of grammatical structures. The sentences attempted are simple or contain faulty attempts at complexity, such as 'The more important target of science ought to be improve individuals lifestyle' (incorrect infinitive structure) and 'if science grow up in their life then they can' (subject-verb agreement error and awkward phrasing). Frequent errors in grammar and punctuation are present in nearly every sentence, which causes some difficulty for the reader and restricts the text to a Band 4.0.
