Task Achievement / Task Response — Band 4.0
The response attempts to address the task by describing the trends for copper, nickel, and zinc in 2014. However, the coverage of the data is limited and contains significant inaccuracies. For example, the student states that nickel is 'falling state janaury to june', whereas the graph clearly shows nickel starting at +6% in January and staying positive (or fluctuating) before dropping in June. The overview is weak, merely stating 'Overall, the graph illustrate the avarage per monthly change', and fails to clearly highlight the main overall trends, such as the general shift from positive changes early in the year to negative changes around June, followed by a recovery. Ideas are underdeveloped, and data interpretation is confused, placing the response at Band 4.0.
Coherence and Cohesion — Band 4.0
The text is divided into three short paragraphs, but the logical progression and overall coherence are heavily disrupted by poor referencing, confusing sequencing, and weak transitional markers like 'First of all,' and 'On the other hand'. The relationships between sentences are often unclear, such as the abrupt transition in the second paragraph ('firstly nickel price is 6% and ...'). Paragraphing is attempted, but the internal cohesion lacks logical flow and referencing devices (like 'these metals') are repetitive and imprecise. This performance aligns with Band 4.0 descriptors for Coherence and Cohesion.
Lexical Resource — Band 4.0
The lexical range is very basic and repetitive, with frequent spelling and word-choice errors that strain the reader. Examples of errors include 'illustrate' instead of 'illustrates', 'avarage per monthly' instead of 'average monthly', 'janaury', 'intial', 'tp eprice', and 'chnaged'. The student attempts some topic-specific vocabulary ('percentage', 'price', 'change'), but the control over word formation and collocation is weak. Because the vocabulary is repetitive and contains frequent non-systematic errors that impede smooth reading, it fits Band 4.0.
Grammatical Range and Accuracy — Band 4.0
Grammatically, the response relies on simple and often heavily fragmented or run-on sentences. There is a lack of control over basic verb forms and tenses (e.g., 'nickel is falling state janaury to june', 'these three metals very decline in the june months', 'Nickel is increase the 2%'). Punctuation and capitalization are frequently neglected, particularly with months ('janaury', 'june'). Complex structures are rarely attempted accurately. Due to frequent grammatical errors that distort meaning and the absence of error-free complex sentences, a Band 4.0 is appropriate.
