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 7.0)

The most significant goal of scientific advancements should be to benefit the daily lives of mankind. I firmly agree with this statement as science should be used to make breakthroughs in the medical domain and also be used to help improve technology.

They are many diseases today which are considered incurable, such as cancer. Finding solutions to such diseases should be at the forefront of such scientific developments. Curing diseases will help people who are terminally ill live longer and also provide a sense of relief to their loved ones. For example, the procedure of the cornea replacement has allowed blind people to see, which has motivated them to do something meaningful with their lives.

Science should be used to accelerate the development of technology. Research should be done in areas that directly impact the technological world, so those inventions can help make the lives of humans easier. For instance, a lot of research was done in neural networks and deep learning which led to Tesla developing fully self driving cars, which lets the human to rest on long routes.

Destruction of human lives is also a possibility, if research is done in the wrong areas. Research in warfare and nuclear physics has led to the creation of bombs and missiles. Although the development of such weapons is for human protection, whenever they are used, they cause loss of human life.

In conclusion, the main motive of scientific investigations should be to find solutions that assist humans. While research done for malicious outcomes will be detrimental for people, breakthroughs in biology and technology will greatly benefit society.

Task Achievement / Task Response: Band 7.0

Your position is clear from the opening: you agree that science should improve people’s lives, and the conclusion reinforces this view. You address the prompt with relevant arguments about medical research, technology, and the risks of weapons research. The examples of cornea replacement and neural networks help illustrate your points, while the discussion of warfare adds a useful qualification rather than simply repeating your position. This fits a response that addresses the task and extends its ideas with support. To strengthen the development further, explain more precisely how the examples demonstrate broad improvements to people’s lives; for instance, the self-driving-car example is asserted to let people rest, but its practical benefits and limitations are not explored.

Coherence and Cohesion: Band 7.0

The essay has a clear overall progression: an introduction states your position, separate paragraphs develop medical and technological benefits, a further paragraph considers harmful applications, and the conclusion returns to your central claim. The sequence is easy to follow, and signposting such as “For example,” “For instance,” and “In conclusion” helps readers recognise the function of each point. Paragraphing is appropriate and each body paragraph has a discernible focus. To make the flow more flexible and cohesive, connect the ideas within paragraphs more explicitly rather than relying mainly on example markers. For instance, show how the medical example supports the claim about quality of life, and clarify the relationship between the weapons paragraph and your argument that science should prioritise beneficial research.

Lexical Resource: Band 6.5

You use a suitable range of topic vocabulary, including “scientific advancements,” “incurable,” “neural networks,” “deep learning,” and “nuclear physics.” These choices make the discussion specific and show some awareness of academic style. Meaning remains clear throughout, but several expressions are imprecise or awkwardly collocated, which limits the flexibility and precision expected at a stronger level. For example, “the procedure of the cornea replacement” is not a natural phrase, and “the technological world” is vague. “Mankind” and repeated references to “humans” also make the wording less natural than more precise alternatives such as “people” or “society.” Aim to choose established collocations and avoid broad or repetitive terms.

Grammatical Range and Accuracy: Band 6.5

You attempt a mix of simple and complex structures, including conditional phrasing (“if research is done in the wrong areas”) and relative clauses (“which has motivated them…”). Most sentences communicate the intended meaning, and the paragraph structure gives you opportunities to vary sentence forms. Some grammatical errors remain, however. “They are many diseases” should be “There are many diseases”; “the human to rest” needs a plural or a different construction, such as “people to rest”; and “which lets” does not agree with the plural subject “cars” (use “which let”). The sentence beginning “Although the development…” is also a fragment because its dependent clause is not joined to a main clause. Check agreement and ensure every sentence has a complete main clause.
