Task Achievement / Task Response — Band 3.0
The response is significantly off-topic. The prompt asks for a summary of a chart regarding fast food consumption in the USA, but the student describes a diagram of a geothermal power plant. Furthermore, the response is under the 150-word minimum, which negatively impacts the score. Because the content does not address the provided task at all, it fails to meet the basic requirements of the prompt. The main features of the actual data are entirely absent, resulting in a very low score for task achievement.
Coherence and Cohesion — Band 4.0
The essay lacks logical progression and clear paragraphing. While there are headings like 'Body 1' and 'Body 2', the internal structure is disjointed. Cohesive devices are either missing or used incorrectly, such as 'As the finally power supply', which makes the flow of information difficult to follow. The lack of a clear introduction or conclusion further hinders the overall coherence of the piece.
Lexical Resource — Band 4.0
The vocabulary is very limited and repetitive. The student relies on basic terms like 'water', 'hot', and 'power', and struggles to use technical or descriptive language accurately. There are several instances of word-choice errors, such as 'expectation' used in place of 'components' or 'equipment'. The range of vocabulary is insufficient to convey complex ideas or describe a process effectively, keeping the score in the lower bands.
Grammatical Range and Accuracy — Band 4.0
The grammar is highly problematic throughout the text. There are frequent errors in sentence structure, such as 'it is process of geothermal power plant' (missing articles) and 'the cold water down 4.5 km and hand hot collected' (unclear syntax and incorrect verb usage). The response lacks complex sentence structures, and the frequent grammatical errors often impede the reader's understanding of the intended meaning.
