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 6.0)

Many people in the world argue that the most important aim of science should be to improve people's lives. I firmly disagree with the statement that improving people's live should be the driving force of science and innovations.

Science is the most important building block of innovations all over the world.It can not be denied that the electricity, the bulbs, mobile phones, internet and all such things are the rewards of deep and intense research in science and technology.Almost everything we use today is a part of scientific innovations that were carried out over the years and this innovations have improved people's lives significantly. For example, cars are the prime example of how science has improved people's lives by making daily comute and transportation easy.Hence it is of no doubt that science has helped and will continue to help improve people's lives.

On the other hand, according to my opinion improving people's lives should not be the most important aim of science because this will create boundaries for scope of research and innovations. Many scientific discoveries does not improve people's lives directly but are equally important as other discoveries. For example, space rockets are not important for our everyday lives but the innovation of space rockets is important for increasing the scope of research and discovering new possibilities. Also a lot of scientific expeditions are carried out for research and exploration of the flora and fauna which does not improve people's lives at all, but such discovery experiments are necessary in order to explore about the planet Earth.

Therefore, I disagree on the argument that most import aim of science should be to improve people's lives as science can not be limited just to improve people's lives. Science should be carried as a means of discovering new possbilities and not solely feed human requirements.

Task Achievement / Task Response: Band 6.5

Your position is clear: you disagree that improving people’s lives should be science’s most important aim, and you address the opposing view before explaining your own. The examples of cars, space rockets, and research into flora and fauna are relevant. The response also recognises that science has improved daily life, which helps show awareness of both sides. This meets the task well, though the support is uneven: the car example illustrates benefits but does not develop the case for your position, while the space-research point is only briefly explained. To strengthen the argument further, explain more precisely how curiosity-driven research can produce knowledge or benefits beyond immediate human needs, and develop each example’s connection to your claim.

Coherence and Cohesion: Band 6.0

The essay has a clear overall structure: an introduction, a paragraph acknowledging science’s practical benefits, a paragraph presenting your disagreement, and a conclusion. Transitions such as “On the other hand” and “Therefore” make the main stages easy to follow. However, some links feel mechanical, and the first body paragraph spends considerable space supporting the view that you ultimately reject before the counterargument is fully established. Within paragraphs, ideas sometimes run together, particularly in the list of scientific inventions and the explanation of exploration. Use clearer sentence boundaries and make each paragraph’s central purpose more consistent. Referencing could also be more precise: “this innovations” does not clearly or correctly refer back to the inventions mentioned.

Lexical Resource: Band 6.0

You use an adequate range of topic vocabulary, including “scientific discoveries,” “scope of research,” “exploration,” and “flora and fauna.” These terms help communicate the subject and your main argument. There are also attempts at more formal phrasing, such as “driving force” and “solely.” However, some word choices and collocations are inaccurate or repetitive: “daily comute,” “discovering new possibilities,” and “feed human requirements” are not natural in these contexts. Spelling errors such as “possbilities” and “comute,” along with repeated use of “important,” reduce precision. Aim for more idiomatic academic expressions and check spelling carefully; this would make your ideas sound more fluent and exact.

Grammatical Range and Accuracy: Band 5.5

You use both simple and complex sentence forms, including clauses introduced by “because,” “which,” and “that,” and your meaning is generally clear. Some sentences are controlled, such as “Many scientific discoveries does not improve people’s lives directly but are equally important as other discoveries,” although this example contains a subject–verb agreement error. Other errors include “this innovations have improved,” “discoveries does not,” and “I disagree on the argument.” There are also punctuation and spacing problems, such as missing spaces after full stops and the run-on presentation of the inventions list. Review agreement, articles and prepositions, and separate long sentences more carefully. Greater accuracy across these structures would improve control without sacrificing complexity.
