Student answer (Band 6.5)

It is often argued, that the scientific inventions are just to ease the life of people, while others believe it has several drawbacks. I strongly agree with the science clear aim of convenience and safety.

Firstly, science made a wonderful inventions and discoveries. It is more related to human well-being and easiness. For example, the invention of telephone was the major breakthrough in the history of science and technology. It's not only reduced the distance between people from distant parts of the world, but also made the communication much more faster, reliable and convenient. Now people can make video calls, text messages, conduct online business meetings, and easy access to social media and content creation. It is like all in one device with plenty of features. Life has become fast-paced and quite relaxing with the wonders of science.

Secondly, with the aid of science, people gained much knowledge about life and how it works. For example, in this modern age of technology health care system has improved significantly. Compared to past, now there are treatments for almost every disease and surgeries are going successful. Doctors are highly professional with the advanced knowledge of health care.

Turning to the other side, science has also become devastated both for society and biodiversity. For example, transportation has adverse effect on public health along with its benefits like noise pollution and air pollution, which lead to chronic diseases. Though, it can be reduced by introducing electric buses and more public transport.

All things considered, science has become essential part of human lives. Science not only make the life easier but also fast and compact. It has added trust and reliability in every aspect from the very first invention (wheel) to latest technologies. Although, it has several drawbacks but it's advantages outweigh the disadvantages.

AI examiner evaluation

Task Achievement / Task Response — Band 6.5

You have addressed the prompt by taking a clear position and providing relevant arguments. You discuss the benefits of science for human well-being and healthcare, and acknowledge the drawbacks, such as pollution. However, the development of your ideas is somewhat limited. For instance, the discussion on healthcare is brief and could be further extended with more specific examples or deeper analysis of how science specifically improves the quality of life. The conclusion is a bit repetitive and could better synthesize your main points. To reach a higher band, ensure that each paragraph fully explores the implications of your arguments rather than just listing examples.

Coherence and Cohesion — Band 6.5

The essay is logically organized with a clear introduction, body paragraphs, and a conclusion. You use transition signals like 'Firstly', 'Secondly', and 'Turning to the other side' to guide the reader. However, some cohesive devices are used mechanically, and there are instances where the flow between sentences could be smoother. For example, the transition to the counter-argument is a bit abrupt. Additionally, some referencing is slightly unclear, such as 'It is more related to human well-being', where the antecedent for 'It' is not immediately obvious. Improving the variety of linking words would enhance the overall flow.

Lexical Resource — Band 6.0

You demonstrate an adequate range of vocabulary for the task, using terms like 'breakthrough', 'fast-paced', 'biodiversity', and 'chronic diseases'. However, there are some inaccuracies in word choice and collocation, such as 'science made a wonderful inventions' (should be 'science has made wonderful inventions') and 'surgeries are going successful' (should be 'surgeries are successful'). You also use 'easiness' where 'convenience' or 'ease' would be more appropriate. To improve, focus on using more precise collocations and ensuring that your word forms are grammatically correct in context.

Grammatical Range and Accuracy — Band 6.0

You attempt a mix of simple and complex sentence structures, which is good. However, there are frequent errors in grammar and punctuation that occasionally hinder the reader. Examples include 'It is often argued, that...' (unnecessary comma), 'made the communication much more faster' (double comparative), and 'Science not only make the life easier' (subject-verb agreement error). While these errors do not prevent the meaning from being understood, they are frequent enough to keep the score in the 6.0 range. Focusing on subject-verb agreement and avoiding redundant comparative structures will help improve your accuracy.
