Student answer (Band 6.5)
Science play`s a vital role in humans lives. In my viewpoint i totally agree that science should develop to improves people`s lives and make lives happy and prosperous.
The most important reasons that i agree because science is the driving power for the technology. For example advancement in science in the field of radiography which leads to the innovation of X-rays machines which help many people to detect bone damage. Nowdays doctors can easily examine the internal parts of the body using MRI and X-ray and provide proper prescription which helps human to cure fast and before serious illness. This develoment lead to making human lives easy and curring of disease without huge damage to body. Hence due to advancement in science and technology people can save their lives.
Another imprtant reasons is innovation of Ethanol, which is purley because of advance research in science. Ethanol is made form the waste of sugarcane, which is processed in industry added with some chemicals and can be used as a fuel. This helps to keep the environment clean causing less pollution as well as helps to preserve natural resources for our futher generation. Ethanol is blended with the petrol and is currently used in vehicles, which leads to reduce in fuel consumtion.Hence science helps to invent such fuels that can be used with the petrol to reduce consumpation.
In summay, it is clear that science hould develop to improves people`s lives. In this essay we discussed two major innovation of science, the first is radiography whch helps in early disease detection and secondly innovation of ethanol which is used to reduce pollution and preserve natutal resources.

Task Achievement / Task Response — Band 6.5
The response addresses the prompt by taking a clear position in favor of science improving lives. The ideas are relevant, focusing on medical advancements and environmental sustainability. However, the development is somewhat limited; while the examples of radiography and ethanol are pertinent, the explanation of how these specifically relate to the 'most important aim' could be more deeply explored. The essay maintains a consistent position throughout, but the conclusion is slightly repetitive, merely summarizing the points rather than synthesizing the argument.
Coherence and Cohesion — Band 6.5
The essay is organized into logical paragraphs, each with a clear focus. Cohesive devices are used, such as 'For example', 'Another important reason', and 'In summary', which help guide the reader. However, the use of these devices is sometimes mechanical or repetitive. Additionally, there are minor issues with referencing and flow, such as the transition between the introduction and the first body paragraph. Paragraphing is used appropriately, but the overall progression of ideas could be smoother to achieve a higher band.
Lexical Resource — Band 6.0
The vocabulary is adequate for the task, allowing the student to communicate their ideas clearly. There are attempts to use topic-specific vocabulary like 'radiography', 'innovation', and 'sustainability' (implied). However, there are several spelling errors ('Nowdays', 'develoment', 'curring', 'imprtant', 'purley', 'futher', 'consumpation', 'summay', 'whch', 'natutal') and some awkward phrasing ('driving power for the technology'). These errors are frequent enough to occasionally distract the reader, though they do not impede overall understanding.
Grammatical Range and Accuracy — Band 6.0
The student uses a mix of simple and complex sentence structures, but there is a high frequency of grammatical errors. Common issues include subject-verb agreement ('Science play`s', 'science should develop to improves'), missing articles, and incorrect punctuation (misuse of apostrophes in 'humans lives' and 'people`s'). While the meaning is generally clear, the persistent errors in basic grammar and punctuation limit the score. To improve, the student should focus on proofreading for subject-verb agreement and consistent verb tense usage.
