Student answer (Band 5.0)
The given figure illustrates the performance and formation of mechanical arm compare to human arm. Overall, the manufactory of artifical arm includes motors and metal equipments for use in any effectorless work.
Fristly, the base is made in adjustable way can be sticked to one palce either can be moved occasionally. Followed by the shoulder it helps in rising and lowering of the arm. In addition to, the pivot enables the arm to rotate in all direction just like the work of a human arm. The mechanism of eblow allows with flexibility as well as for other movement to reach out this attached with wirst making it to flex and rotate, also it plays role in griping.
Finally the gripper, which perform as human finger. The grip has a sensor built-in that control force. The whole management is conducted by three motors situated in base, elbow and at the joint of wrist and grip, these motors are contorled by a computer which precise the function.

Task Achievement / Task Response: Band 5.0
The student attempts to describe the main features of the mechanical arm and its functional correspondence to a human arm. An overall summary is provided, and key components such as the base, shoulder, pivot, elbow, wrist, and gripper are mentioned. However, there are several inaccuracies in reporting the visual data. For instance, the text states that the three motors are 'situated in base, elbow and at the joint of wrist and grip,' whereas the diagram shows all three motors connected directly to the computer at the top, with individual lines leading to the elbow, wrist/arm section, and gripper. Furthermore, some functional descriptions are vague or inaccurate, leading to a score of 5.0.
Coherence and Cohesion: Band 5.0
The response is organized into three paragraphs, attempting an introductory overview, a body paragraph detailing specific parts, and a concluding remark. However, the logical progression is hindered by frequent structural issues and awkward transitions, such as starting paragraphs with 'Fristly' and 'Finally the gripper'. Cohesive devices are either missing or applied mechanically, and referencing between sentences is occasionally unclear, making the flow somewhat disjointed. Paragraphing is present, but internal cohesion requires improvement to reach a higher band.
Lexical Resource: Band 5.0
The vocabulary used is limited and contains numerous errors in word choice and spelling (e.g., 'manufactory', 'artifical', 'Fristly', 'palce', 'rising', 'eblow', 'wirst', 'griping', 'contorled', 'precise', 'equpiment'). While the student attempts less common terminology related to the diagram (such as 'effectorless', 'alternative end-effectors', and 'sensors'), the high frequency of lexical and spelling errors noticeably impairs readability and restricts the lexical score to a 5.0.
Grammatical Range and Accuracy: Band 5.0
The essay displays a very limited range of grammatical structures, relying heavily on simple or awkwardly fused sentences. There are frequent grammatical errors, incorrect prepositions, and punctuation issues throughout the text, such as 'base is made in adjustable way can be sticked', 'allows with flexibility', and 'drill a holes'. Complex sentences are frequently faulty (e.g., 'either can be moved occasionally'), which can cause difficulty for the reader and places the performance firmly at Band 5.0.
