Task Achievement / Task Response — Band 3.0
The response fails to meet the minimum length requirement of 250 words, containing only 73 words. Because of this extreme under-length, the ideas cannot be adequately developed, resulting in a severely restricted treatment of the prompt. While the writer touches upon the general theme of science improving lives by mentioning diseases, earthquakes, and technology, the position is undeveloped and lacks supporting evidence or examples. Consequently, this performance falls below the Band 4 descriptor, as the response is minimal and tangential due to the lack of sufficient content.
Coherence and Cohesion — Band 4.0
The text consists of a single, run-on paragraph without any logical structure, paragraphing, or meaningful cohesive devices. Sentences are strung together with repetitive conjunctions or simply juxtaposed without clear transitions. There is no clear overall progression of ideas, making the progression difficult to follow. This aligns with the Band 4 descriptor, where information and ideas are not arranged coherently and cohesive management is largely absent.
Lexical Resource — Band 4.0
The vocabulary used is extremely basic, repetitive, and plagued by severe word-choice and collocation errors (e.g., writing 'devolop our live' instead of 'develop our lives', 'faciltate to go in galaxy', and 'itelligent person'). The range of vocabulary is very limited and inadequate for discussing academic topics. Due to the frequent errors and restricted lexical choices that frequently strain the reader's understanding, the response corresponds to a Band 4 level.
Grammatical Range and Accuracy — Band 4.0
Grammatical range and accuracy are severely limited. The text relies on simple, poorly constructed sentence forms with persistent, fundamental errors in subject-verb agreement, pronoun usage ('he help', 'his going'), and tense consistency. There is a complete lack of complex structures, and punctuation is entirely absent. The frequency of grammatical errors constantly distorts meaning and causes significant difficulty for the reader, fitting the Band 4 descriptor.
