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 4.5)

I agree to the statement, "The most important aim of science should be to improve people's lives". Wheels are the main part of automobiles. What if that wheel is not round but in sqaure? We can't ride bicycle, auto, motorbikes, cars, etc., So they have found that if the wheels are round, it's easy to move the cart and it's easy to carry. That's science. What if we don't have science? We all know about Sir Issac Newton. He discovered Force. And because of that we got to know about physics, which has kinetics, dynamic, static, and more and more. Science is Technology and Technology is Science. Those two terms are inter related. During old days we don't have anything like smartphones. But now technology have improved such that we got different models of smartphones. Science is related many terms. Shall i say something? Food is also a part of Science. Do you know how we are getting curd from milk. There is Science behind. The milk is turning into curd because of a bacteria. I just said an example. Science is involved in almost everything around us. But in some cases, we shoud not use science in wrong way. You know some scientist may test something and if that goes wrong it will affect the people and our environment. Science should be used in carefull way, such that it should benefit the people's life. And it should also improve people's lives. We live in the Universe which is surrounded by Science. Science is more important than we are thinking. Life starts with science and also ends with science. Our birth has science behind it and our death also has science behind it. So, "Science is everything."

Task Achievement / Task Response: Band 5.0

Your position is clear from the opening: you agree that science should aim to improve people’s lives, and you return to this idea when arguing that it should be used carefully and benefit people. The examples of transport, smartphones and curd-making are relevant illustrations of science’s presence in everyday life. However, the response only partially develops the question of what science’s most important aim should be. Several examples explain that science exists or is useful, rather than showing why improving lives should take priority over other aims. The references to Newton and science being “everything” are broad, and the risks to people and the environment are mentioned but not explained. Develop fewer examples with clearer reasoning about their benefits and limitations.

Coherence and Cohesion: Band 3.5

The response has a recognisable line of thought: it begins with agreement, gives everyday examples, then introduces the need to use science carefully before concluding. However, ideas are presented in one continuous paragraph, so the reader has little help distinguishing the main argument from supporting examples. Progression is also weak: the discussion jumps from wheels to Newton, smartphones, food, and the universe, with limited explanation of how each point advances the answer. Repeated questions such as “What if we don’t have science?” and “Do you know how…” create a conversational sequence rather than a developed essay. Use separate paragraphs for the position, developed reasons, and conclusion, and connect examples explicitly to the central claim.

Lexical Resource: Band 5.0

You use a range of topic-related words, including “automobiles,” “bacteria,” “environment,” and “technology,” and the reader can generally understand the intended meaning. However, vocabulary is often repetitive or imprecise: “Science is involved in almost everything” and “Science is everything” repeat a broad claim without adding precision. Some expressions are awkward for an academic essay, such as “Science is Technology and Technology is Science” and “in carefull way.” There are also spelling errors, including “sqaure,” “Issac,” “shoud,” and “carefull,” which reduce accuracy. Aim for more precise terms to describe scientific applications and outcomes, and check spelling and collocations carefully.

Grammatical Range and Accuracy: Band 5.0

Most sentences use straightforward structures, and the main message is usually understandable. You also attempt longer sentences, for example, “You know some scientist may test something and if that goes wrong it will affect the people and our environment,” but control becomes less reliable as clauses are joined. Errors occur frequently in verb forms and agreement: “During old days we don’t have” and “technology have improved” do not use appropriate tense or agreement. Other examples include “Science is related many terms” and “because of that we got to know,” where grammatical relationships are unclear or awkward. Sentence boundaries and punctuation also need attention, particularly around the rhetorical questions and lists. Practise accurate simple sentences first, then build longer sentences with clear clause links.
