IELTS Writing Task 2 question

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)

It is often argued that, the foremost purpose of scientific endeavor is to ameliorate human welfare.

I wholeheartedly agree that, I largely concur with this statement. Even though other aims exist, improving life should be our priority. And science has also yielded unprecedented advances in transforming healthcare. Especially, life-saving vaccines, combat pandemic, innovative surgical procedure and early disease detection increase the longevity of human being.

Because of it, life quality enhances, mortality rate reduces and human suffering also decrease. Moreover, scientific progress also addresses fundamental human needs. Because of innovation in agricultural biotechnology, ensured food security, renewable energy technology and access to clean water, large groups of population are able to eat food that is inexpensive.

It also helps in uplifting communities, it quickens sustainable development and eradicates poverty. While there are some people who argue that science should only focus on improving lives and stop the projects like space and ocean exploration. And they think that is just wastage of our resources. But I believe that would help humanity in long term race.

Because of it, humanity gets to know about space, quantum physics, astrophysics and it also broaden human understanding. But some people still reject this notion by saying that the funding of these scientific practices come from tax money of public so they should only focus on the problems of public. And they think founding a new star or new specie bring no benefit to their life. But still it is only way we are different from the all other species on this planet.

AI examiner evaluation

Task Achievement / Task Response — Band 6.0

The response addresses the prompt and maintains a clear position throughout. You successfully argue that while improving lives is the primary goal, scientific exploration (like space) is also vital for long-term progress. However, the development of ideas is somewhat uneven. For instance, the paragraph regarding space exploration is a bit repetitive and could have been more tightly linked to the 'improving lives' argument by explaining how such research eventually leads to practical applications. While the main points are relevant, some arguments, such as the mention of 'quantum physics,' are introduced but not fully explained in relation to the prompt's core theme of human welfare.

Coherence and Cohesion — Band 5.5

The essay is organized into logical paragraphs, each with a clear focus. You use some cohesive devices like 'Moreover' and 'While,' which help the flow. However, there are instances where the connection between sentences is slightly mechanical or abrupt. For example, starting sentences with 'Because of it' repeatedly creates a repetitive structure that hinders the natural flow of ideas. Additionally, the paragraphing is functional, but the transition between the discussion of agricultural benefits and the counter-argument regarding space exploration could be smoother to better guide the reader through your line of reasoning.

Lexical Resource — Band 5.5

You demonstrate an adequate range of vocabulary for the task, using terms like 'ameliorate,' 'unprecedented,' and 'biotechnology' effectively. There are some minor errors in word choice and collocation, such as 'combat pandemic' (should be 'combating pandemics') and 'founding a new star' (should be 'discovering a new star'). While these errors do not impede communication, they indicate a need for more precise control over word forms and collocations. To reach a higher band, focus on using less common lexical items more accurately and ensuring that your word choices are consistently appropriate for an academic context.

Grammatical Range and Accuracy — Band 5.5

The essay uses a mix of simple and complex sentence structures. While you attempt complex sentences, there are frequent grammatical errors, particularly with subject-verb agreement and article usage (e.g., 'human suffering also decrease' instead of 'decreases'; 'all other species' instead of 'all other species'). Punctuation is also inconsistent, with unnecessary commas appearing after 'argued that,' and 'agree that,'. These errors are noticeable but do not prevent the reader from understanding your main points. To improve, focus on proofreading for basic agreement and refining your use of complex sentence structures to ensure they are error-free.
