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 6.5)

The primary motive of science should be to enhance the people's lives. I completely agree with the statement as there are multiple reason to endorse it that will be justified in the upcoming paragraphs.

The primary reason to science in improving lives of humans is that it will lead to peaceful and better quality of life. If science is used in betterment of humans there will be no wars between nation. As a result, the people can live without any fear of destruction and peacefully at any location in the world. Another reason, is that it will help the mother nature to prosper. To elaborate, the science used to improve the quality of life will focus more on saving the precious resources such as water, food and land. Hence, this will only happen if people will take care of environment and surrounding.

On the other hand, it is also very crucial to use science apart from the betterment. The main reason is to protect the earth from outer space asteroids and meteors. To put it more vividly, Many destructive weapons are being made, in motive to deviate the route of space objects which can cause massive destruction if fall on earth. As a result by bombarding the missiles the route can be diverted in order to save the earth.

In conclusion, although science used to develop destructive weapons is essential to save humanity and mother earth, however the science used to enhance the lives of the people is even more important because it can lead to peaceful life and also save environment.

Task Achievement / Task Response: Band 6.5

Your position is clear from the opening: you completely agree that improving people’s lives should be science’s primary aim, and the conclusion returns to this view. You give relevant reasons, including peaceful living, protecting natural resources and using technology to divert dangerous space objects. This covers the task, and the asteroid example adds a useful qualification by recognising another important scientific purpose. However, some claims are asserted rather than explained: for example, the link between science improving lives and there being “no wars between nation” needs a clearer chain of reasoning or a concrete example. The environmental point is also brief. To develop the response further, explain how particular scientific advances improve lives and weigh these benefits against other scientific aims.

Coherence and Cohesion: Band 6.5

The response has a coherent overall structure: an introduction states your view, the body paragraphs present supporting reasons and a qualification, and the conclusion restates your position. Signposts such as “Another reason,” “On the other hand” and “In conclusion” help readers follow the progression. The organisation is generally effective, though some connections feel mechanical or unclear. For instance, “On the other hand” introduces a related qualification rather than a direct opposing view, and “Hence, this will only happen if…” does not clearly show how the previous point leads to the next. Referencing in “it will help” and “this will only happen” could also be more precise. Use transitions that express the exact relationship between ideas and make each paragraph’s reasoning progress step by step.

Lexical Resource: Band 6.0

You use an adequate range of topic-related vocabulary, including “quality of life,” “precious resources,” “destructive weapons” and “massive destruction.” These choices make the main ideas understandable, and you attempt more formal phrasing. Some word choices and collocations are inaccurate or awkward, however, such as “primary reason to science,” “in motive to deviate” and “if fall on earth.” Repetition of “improve,” “lives” and “science” also limits flexibility. Aim for more natural combinations and precise verbs—for example, describe science as “contributing to” human welfare, and say that a threat “could strike Earth.” Check word forms and spelling, including “nature” where you mean “the environment,” and use consistent capitalisation for “many.”

Grammatical Range and Accuracy: Band 6.0

You use a mix of simple and complex forms, including conditional structures such as “If science is used…” and a relative clause in “weapons … which can cause massive destruction.” The overall meaning remains clear, but some grammatical errors recur. Examples include the plural and article problems in “multiple reason” and “between nation,” the missing subject in “if fall on earth,” and the awkward conditional form “if people will take care.” There are also punctuation issues, such as the unnecessary comma after “Another reason” and the run-on construction “although …, however …” in the conclusion. Practise accurate agreement, articles and conditional clauses, and avoid combining “although” with “however” in the same sentence. Greater control of these forms would make your varied sentences more fluent.
