Task Achievement / Task Response — Band 5.5

The response is significantly under the 150-word minimum requirement, which severely limits the ability to address the task. Because the text is incomplete and stops abruptly after only 79 words, it fails to provide a summary of the main features or make the necessary comparisons between the mechanical and human arm. The content provided is too brief to develop any ideas, resulting in a failure to meet the basic requirements of the prompt. To improve, you must ensure you complete the full analysis of the diagram and meet the word count threshold.

Coherence and Cohesion — Band 5.5

The response shows an attempt at paragraphing, but the text is too fragmented to establish a logical flow or progression. While there is a basic introduction and a transition phrase ('To initiate with'), the abrupt ending prevents the development of a coherent structure. Cohesive devices are used in a very limited and mechanical way. To improve, focus on planning your response to ensure you have a clear introduction, a body paragraph that groups information logically, and a concluding summary, all while maintaining a consistent flow of ideas.

Lexical Resource — Band 5.5

The vocabulary is limited and repetitive. There are noticeable errors in word choice and collocation, such as 'working of mechanical arm' (missing article) and 'comanding the motors' (spelling error). The phrasing 'represents the efforts of individuals in making' is unclear and lacks the precision required for a technical description. To improve, focus on using more precise terminology related to mechanical processes and ensure you use articles and prepositions correctly. Expanding your range of descriptive verbs and nouns will help you convey information more accurately.

Grammatical Range and Accuracy — Band 5.5

The response contains several grammatical errors that hinder clarity. Examples include 'different parts plays their role' (subject-verb agreement error) and 'functioning as same as in humans arm' (incorrect comparative structure and possessive form). The sentence structures are simple, and the frequent errors in basic grammar and punctuation indicate a lack of control. To improve, practice subject-verb agreement and the correct use of articles. Aim to incorporate a wider variety of sentence structures, such as passive voice, which is often necessary for describing technical diagrams.
