Student answer (Band 5.0)

The given picture chart depicts about the process of producing ethanol .its shows several steps of production in diagram.

overall, eathanol production has 7 total stages. fist stages shows plants and grows with solar energy ,followed harvesting .after production releases carbon dioxide.

Initially, vasrious kind of plants and trees grow in under sunlight and with solar energy ,when plants grows fully harvesting started then help of tractor or vehicles its turns into small pieces it called pre processing and turns into cellulose.

futhermore,cellulose send for producing in chemical form followed this step its turn to sugars .Finally microbes added in sugars and ethanol produced after thaat it send to people for there uses like as for car ,truck and airplan last but not least these vehicles release carbon dioxide.

Task Achievement / Task Response — Band 5.0

The response attempts to summarise the process of biofuel production as shown in the diagram. However, the task is under-length, containing only 129 words against the required 150-word minimum, which impacts the overall development of the response. While the writer manages to identify the circular nature of the process and mentions several key stages such as plant growth, harvesting, pre-processing, cellulose formation, sugar conversion, and ethanol creation, the description lacks sufficient detail. The overview is overly simplistic, stating 'eathanol production has 7 total stages', and the connection between ethanol usage and the release of carbon dioxide closing the loop is only briefly touched upon. Consequently, the task is only partially addressed.

Coherence and Cohesion — Band 5.0

The essay is divided into four short paragraphs, attempting an introduction, an overview, and body paragraphs. However, logical progression is frequently disrupted by poor cohesion and erratic punctuation. Transitional phrases like 'futhermore' and 'Initially' are used, but they are often undermined by missing spaces, random capitalization, and run-on sentences. For instance, the transition between steps lacks smooth linkage, making the overall arrangement somewhat disjointed. Paragraphing is attempted, but the internal cohesion within paragraphs is faulty due to mechanical referencing and inadequate punctuation.

Lexical Resource — Band 4.5

The lexical range is limited and repetitive. The writer uses basic vocabulary such as 'plants', 'trees', 'energy', 'sugars', and 'ethanol'. There are several spelling errors throughout the text, including 'eathanol', 'fist', 'vasrious', 'futhermore', 'thaat', and 'airplan'. Attempts at less common vocabulary or subject-specific terms are minimal or inaccurate, as seen in phrases like 'chemical form' or 'pre processing and turns into cellulose'. These lexical limitations and frequent spelling errors cause some difficulty for the reader.

Grammatical Range and Accuracy — Band 4.5

The response exhibits a very limited range of grammatical structures, relying mostly on simple and flawed complex sentences. There are frequent, persistent errors in punctuation, capitalization, and sentence boundaries. Examples include missing periods or commas, running clauses together without proper conjunctions ('plants grows fully harvesting started then help of tractor'), and awkward phrasing ('depicts about the process'). Subject-verb agreement and tense consistency are also problematic ('plants grows', 'harvesting started'). These frequent errors hinder readability and demonstrate weak control over basic grammar.
