The most important aim of science should be to improve people’s lives. To what extent do you agree or disagree with this statement? Give reasons for your answers and include any relevant examples from your own knowledge or experience.

 

Student answer (Band 5.5)

I am one hundred percent agree with this statement that scientific knowledge is must used for the betterment of humanity. Because with the use of scientific knowledge, the living standards of the every single person can be improved. At present all of the modernity of the world is just due to the right use of science and it's inventions like if we start discussing related to current technology that AI tools are helping in every aspect of life . We use airplane for travelling hundreds of miles in only few hours while in past it takes months to travel from one country to another country. Similarly for contacting people we use letters or pegion as a fast communication. Science is improving life in every aspect of life like if we talk about health sector a lots of techniques are introduced for different types of diseases . For example for kidney stones we use ultra lights for the breakdown of stones into pieces without cutting the body or operation. We are able to identify the every type of disease through blood sample or even we can recognise the whole human only with his finger prints or hair . Now we are able to study the complete human genome sequence and through this we could be able to prescribe personalised medicine for individual. Using stem cells technology scientists can grow the human body parts if any one damaged. Now if we discuss about defence fields science play a very crucial role in developing atomic weapons which although I personally think not good for humanity but it is used to threat your enemy which is also due to the scientific knowledge. So know if I give you a personal example that my mother is a diabetic patient so we use insulin for her which is produced through a Bactria and all of this is possible due to scientific progress. I think it is all depends on humans that how they use the science or scientific knowledge either for betterment of devastation of humanity

AI examiner evaluation

Task Achievement / Task Response — Band 5.5

The response addresses the prompt by taking a clear position in favor of science improving lives. However, the development of ideas is somewhat uneven. While you provide relevant examples like medical advancements (insulin, kidney stone treatment), the discussion on defense and atomic weapons is slightly contradictory to your main thesis and lacks depth. The structure is essentially a single long paragraph, which hinders the full development of your arguments. To reach a higher band, ensure you organize your ideas into distinct paragraphs—one for each main supporting point—and provide a more balanced exploration of the 'extent' to which you agree, perhaps acknowledging potential counter-arguments more formally.

Coherence and Cohesion — Band 5.5

The essay lacks paragraphing, which is a significant issue for coherence. The entire response is presented as one block of text, making it difficult for the reader to follow the progression of your arguments. While you use some cohesive devices like 'Similarly', 'For example', and 'Now', their use is sometimes repetitive or mechanical. The flow of ideas is generally logical, but the lack of clear transitions between different thematic areas (e.g., moving from transport to medicine to defense) makes the essay feel like a list of points rather than a cohesive argument. Using clear paragraph breaks is essential for better organization.

Lexical Resource — Band 5.5

You demonstrate an adequate range of vocabulary for the task, using terms like 'human genome sequence', 'personalised medicine', and 'stem cells technology'. However, there are several instances of awkward phrasing and word choice errors, such as 'modernity of the world' instead of 'modern world', 'ultra lights' instead of 'ultrasound', and 'Bactria' instead of 'bacteria'. These errors occasionally distract the reader. To improve, focus on learning the correct collocations for scientific terminology and avoid over-relying on basic descriptors. Expanding your range to include more precise academic vocabulary will help elevate your score.

Grammatical Range and Accuracy — Band 5.5

The essay contains a mix of simple and complex sentence structures, but there are frequent grammatical errors that persist throughout the text. Examples include 'I am one hundred percent agree' (should be 'I one hundred percent agree' or 'I am in complete agreement'), 'scientific knowledge is must used' (should be 'must be used'), and 'it is all depends' (should be 'it all depends'). Punctuation is also inconsistent, with missing spaces after commas and periods. While these errors do not completely impede communication, they are frequent enough to lower the overall accuracy score. Focus on subject-verb agreement and correct verb forms.
