The diagram demonstrates the data regarding seven various stages such as tap on, cover hole with finger, fill top bottle to overflow, level constant, finger away from hole, level per minute and empty as well as repeat the process for timing things to make own water clock.

Overall it is noticeable that the whole process is depending on water supply and plastic bottle to make clock.

Firstly, it Is illustrate the idea that at first stage we need one plastic bottle which needs to cut in to parts.Then, both parts should be stick by tape on stand.At the other side of bottle, make two small holes one at top of bottle as well as second will be placed at down side of it and put straw attached with glue at top hole .After this, make certain levels per minute by pencil on down part of bottle.At the end put it under the water tap.

Moreover, once the system made, needs to follow some steps such as at beginning tap on and after cover the both holes by finger.Start filling the bottle to top until it will overflow.Then relies the finger and process start.Check every level which indicates minutes.One whole process gives the knowledge about 60 minutes which means one hour.Follow the same process throughout the day.

Task Achievement / Task Response — Band 5.0

The response covers the main stages of the process, but the description is often unclear or inaccurate. For instance, the instruction to 'cut into parts' and 'stick by tape' is vague, and the explanation of the holes and the straw is difficult to follow. The overview is also quite weak, failing to clearly summarise the main stages or the underlying principle of the process. While the response addresses the task, the lack of clarity in describing the mechanical steps means that the information is not fully developed or accurately presented for a reader to understand the process.

Coherence and Cohesion — Band 5.5

The response is organised into paragraphs, which is a positive step. However, the progression of ideas is often disjointed. The use of cohesive devices is mechanical and sometimes misused, such as 'At the other side of bottle' or 'Moreover, once the system made'. The referencing is occasionally unclear, making it difficult for the reader to follow the sequence of the construction and operation phases. While there is an overall attempt at structure, the lack of smooth transitions and logical flow between sentences limits the coherence of the report.

Lexical Resource — Band 5.0

The vocabulary is quite limited and repetitive. There are frequent errors in word choice and collocation, such as 'level per minute' instead of 'calibrating the scale', and 'relies the finger' instead of 'releases'. The phrasing is often simplistic, relying on basic verbs like 'make', 'put', and 'check'. While the meaning is generally conveyed, the lack of precise technical vocabulary related to the process (e.g., 'calibrate', 'aperture', 'overflow', 'interval') prevents the response from achieving a higher band score. The errors do not completely impede communication, but they are noticeable.

Grammatical Range and Accuracy — Band 5.0

The response contains a high frequency of grammatical errors, including issues with articles ('the whole process is depending on water supply'), subject-verb agreement ('once the system made, needs to follow'), and sentence structure ('It Is illustrate the idea'). There is a lack of complex sentence structures, and the simple sentences used often contain errors in tense or word order. Punctuation is also inconsistent, particularly with the placement of commas and periods. These errors are frequent and occasionally make the text difficult to read, though the core message remains understandable.
