In the diagram show how to make a drill machine? in making of machine drill pass by different process then make a good drill machine. If main computer control of machine by it then it send to use. Unfortunately, they send bad machine it cause of an incident.

First, it give machine to check material of machine it give information to computer . Second it check the movement of machine it work aquaritly it give information to the computer . Third it check the built in scupper control force if it right they give data computer.

After that all process create a good machine that use to different work make easy.

AI examiner evaluation

Task Achievement / Task Response — Band 3.0

The response fails to address the prompt effectively. Instead of describing the mechanical arm and its joints as shown in the diagram, the text drifts into an irrelevant narrative about a 'drill machine' and a hypothetical incident involving a 'bad machine.' The instructions specifically asked for a summary of the mechanical arm's function and a comparison with human joints, but these key features are entirely ignored. The content is largely off-topic, and the few references to the diagram are vague and inaccurate. Consequently, the response does not provide a clear overview or report the main features as required by the task.

Coherence and Cohesion — Band 4.0

The essay lacks a logical structure. While there is an attempt to use paragraphing, the progression of ideas is disjointed and confusing. The transition between the introduction and the body paragraphs is abrupt, and the use of cohesive devices is mechanical and often misused, such as 'More information the selection of machine.' The referencing is unclear, as the reader cannot follow the connection between the mechanical arm diagram and the narrative about a drill. The lack of logical flow makes the text difficult to follow, and the ideas do not build upon one another in a coherent manner.

Lexical Resource — Band 4.0

The vocabulary is very limited and repetitive. There are frequent errors in word choice and spelling, such as 'aquaratly' for 'accurately' and 'scupper' (likely a misspelling or misuse of a technical term). The range of vocabulary is insufficient to describe the technical process shown in the diagram. The student relies on basic, often incorrect, phrasing to convey meaning, which frequently impedes the reader's understanding. There is no evidence of an attempt to use precise or academic terminology appropriate for a report on a mechanical process.

Grammatical Range and Accuracy — Band 4.0

The response contains frequent grammatical errors that distort meaning. There are significant issues with subject-verb agreement (e.g., 'The diagram show'), sentence structure, and article usage. Most sentences are simple and contain errors, such as 'In the diagram show how to make a drill machine?' which is grammatically incorrect and confusing. There is no evidence of complex sentence structures, and the persistent errors in basic grammar make the text difficult to read. Punctuation is also inconsistent, further hindering the clarity of the writing.
