overall, one bottle is taped in the top of stand just below to the tap. Where another bottle with neck cutted off is placed in bottom of the stand. All the process is without any machinery and electricity, this all can possible by the help of water.

At the first step that stand is placed below to the tap, there is hole at the bottom of the first bottle which should cover at first and pour the water and straw at the neck it should filled up where water overflow. After that the level of water remains constant, then remove finger from that hole.

Then water continously droped in another neck cutted bottle, in where the second bottle is marked as per minute. After completely filled remove that water and repeat that same process for timming things.

Task Achievement / Task Response — Band 5.0

The response attempts to describe the process of making a water clock, identifying key components such as the tap, bottles, straw, and stand. However, the overview is weak and confused, stating that 'all the process is without any machinery and electricity, this all can possible by the help of water,' which is conversational and lacks academic tone. Furthermore, the description of the sequential steps is difficult to follow and lacks precision. Important stages of the diagram, such as calibrating the measuring bottle and the overflow mechanism, are poorly explained and muddled with grammatical inaccuracies. Consequently, the task is only partially addressed, earning a band score of 5.0.

Coherence and Cohesion — Band 5.0

The text is divided into an introduction and three brief body paragraphs, but the overall progression of ideas is hindered by weak cohesive devices and confusing referencing. Transition phrases like 'overall, one bottle is taped in the top' and 'At the first step that stand is placed' are awkward and mechanical. The pronoun referencing is frequently unclear, particularly when the writer uses 'it' or 'that' without a clear antecedent (e.g., 'at the neck it should filled up where water overflow'). Paragraphing is attempted, but internal logic within the paragraphs is frequently broken, making the sequence of steps difficult to track. This reflects band 5.0 performance.

Lexical Resource — Band 5.0

The vocabulary used is basic, repetitive, and at times inappropriate for an academic report. Words like 'tap', 'bottle', 'straw', and 'jar' are repeated frequently, and the writer relies on descriptive phrases rather than precise technical terms (e.g., 'neck cutted bottle' instead of a severed or inverted bottle). There are notable word-choice errors, such as 'timming things' instead of timing or calibration, and 'pour the water and straw at the neck'. The range of vocabulary is limited and minimally adequate for conveying the basic topic, placing it at a band 5.0.

Grammatical Range and Accuracy — Band 5.0

The student attempts a mix of simple and complex sentence forms, but control over grammar is weak. There are frequent errors in tense, voice, and sentence structure that cause difficulty for the reader. Examples include 'neck cutted off is placed', 'this all can possible by the help of water', 'which should cover at first and pour the water', and 'water continously droped'. Punctuation is also erratic, with missing commas and run-on sentences. The high frequency of grammatical errors places this response firmly in the band 5.0 category.
