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)

The most pivotal objective of scientific techonology should be to enhance the lifestyle of human. I completely agree with the nuance that the primary role of science should be to improve humanity but it is not limited to it.

Science has contributed in several ways to facilitate humans to live a modern life. First of all, advancement in the health sector is the major contribution of science. Introduction of vaccines alleviate the spread of many viral and becterial diseases. Owing to scientific research, the adverse and detrimental effects of many life-threating diseases can be minimized. Secondly, modernisation in agriculture, education, tourism and many other sectors are the gift of scientist's great invention. Scientists are working tirelessly to introduce new ways, machines, gadgets, apps, devices and many more things to bring ease in our lives. Without the intervention of science, we still would be using the moonlight to see at night and do not have any means to preserve foods for longer periods.

However, this holistic and paragmatic approach of science is not just limited to serve for humanity. Science has many other objectives to work on. Scientists are often research because of mere curiosity but most of the time this hunting for information ends up in human's favor. For example, the exploration of outer world. They wanted to foster their knowledge about the life other than humans including aliens. Nevertheless, they discovered communication can be enhanced by introducing spaceships in stratosphere. Whereas, while exploring the oceans, many species have been discovered in the ocean bed. Scientists are thriving for their lfestyle and reproductive cycles. This side of science is known as pure research where curiosity is get information about other animals and living organisms beside humans.

In conclusion, although science has made major contribution in serving people, it serves other purpose too. Not only does it discover the skies beyond our solar system, but also exploring the life inside deepest water bodies.

Task Achievement / Task Response: Band 6.5

Your position is clear: you agree that improving human life is science’s primary aim, while recognising that science also pursues other goals. The health examples—vaccines and reducing the effects of serious diseases—directly support your view, and you address the qualification through curiosity-driven research. This covers both sides of the question and includes relevant examples. However, some points are less fully explained: the references to agriculture, education and tourism are listed rather than illustrated, and the space-exploration example does not clearly show how satellites or spacecraft improved communication. Explain the link between each example and your argument, and develop the distinction between practical benefits and knowledge pursued for its own sake more precisely.

Coherence and Cohesion: Band 6.5

The response has a coherent overall structure: an introduction states your position, the next paragraphs present practical benefits and other scientific aims, and the conclusion returns to the central contrast. Sequencing phrases such as “First of all,” “Secondly,” and “However” help readers follow the main stages. At times, though, cohesion feels mechanical, and some links between ideas are unclear. For example, “Nevertheless” introduces the claimed communication benefit of space exploration without making the relationship explicit, while “Whereas” begins a fragment-like transition to ocean research. The final sentence also shifts from “not only” to “but also” without parallel grammatical structure. Use fewer formulaic transitions and make the cause-and-effect links between examples explicit.

Lexical Resource: Band 6.0

You show an adequate range and make attempts to use less common vocabulary, including “detrimental effects,” “intervention,” “curiosity,” and “reproductive cycles.” These choices help convey the topic, and the overall meaning remains understandable. However, some word choices and collocations are inaccurate or unnatural, such as “scientific technology” for science, “enhance the lifestyle of human,” “gift of scientist’s great invention,” and “hunting for information.” There are also spelling errors, including “techonology,” “becterial,” “paragmatic,” and “lifestlye.” These slips limit precision even when the intended meaning can be inferred. Aim for natural academic collocations and check spelling carefully, especially in key terms.

Grammatical Range and Accuracy: Band 5.5

You attempt a mix of simple and complex structures, including a concessive opening and the inversion “Not only does it discover…”. Some sentences communicate their meaning clearly, but grammatical errors recur and occasionally make relationships difficult to follow. For example, “Introduction of vaccines alleviate” has an article and subject–verb agreement problem; “Scientists are often research” uses an incorrect verb form; and “curiosity is get information” is not a complete, well-formed clause. The final “Not only… but also…” construction is also not parallel. Practise accurate agreement, articles, verb forms and complete clause structures, then proofread complex sentences to ensure their parts fit together.
