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)

Many people argue that the most important purpose of science is to enhance people's lives. Scientific inventions in medicine and technology have made life easier, though they can have significant drawbacks, such as ignoring major issues like poverty and the scarcity of food and water. In my opinion, I agree that the aim of science is to make people's lives better.

Scientific innovations have introduced many medicines, medical equipment, and vaccines. These advancements have led to the prevention of diseases, improved treatment and increased life expectancy. For example, during the pandemic, vaccines helped prevent further spread of the disease. Another rapidly growing field is technological inventions such as the internet, search engines, smartphones and artificial intelligence. Technology has made people's lives easier, as they can communicate effectively and instantly through their mobile phones anywhere in the world. Many social media platforms have also developed, allowing people to build their careers. For example, platforms like Instagram have created new professions, such as influencers and social media marketing agents. Moreover, these advancements make it easier for people to live their lives effectively.

Conversely, there are many drawbacks, such as huge investments in space technology that yield little result. Those funds could address real-world problems such as poverty and the scarcity of food and water. Space inventions can cost millions of dollars and still fail to deliver effective results. In many countries, for instance, around half the population lives in poverty and lacks adequate food or water to survive.

In conclusion, science should aim to improve everyone's lives, not be limited to a select group, ignoring those suffering from poverty.

Task Achievement / Task Response: Band 6.5

Your position is clear: you agree that science should improve people’s lives, and the conclusion reinforces this view. You address both benefits and drawbacks, using relevant examples such as vaccines, communication technology, and investment in space research. This gives the response a sound basis and meets the task. However, the discussion is unevenly developed. The benefits of medicine and technology receive several explanations, while the claim that space research yields little result is asserted rather than supported with a specific example or explanation. The reference to poverty and food or water scarcity is also broad. To strengthen the response, explain how scientific priorities could directly address these needs and clarify whether you oppose space research itself or only excessive spending on it.

Coherence and Cohesion: Band 7.0

The essay has a clear overall structure: an introduction, a paragraph on benefits, a contrasting paragraph on drawbacks, and a conclusion. Ideas generally progress logically, and signposts such as “For example,” “Moreover,” and “Conversely” help readers follow the argument. Paragraphing is appropriate, and the conclusion returns to the central position. Some connections could be more precise, however. The transition from medical advances to social media is understandable but broad, and “Moreover, these advancements” does not clearly identify which developments the sentence refers to. The contrast paragraph also moves quickly from space spending to poverty without fully explaining the link. Use more specific references and develop the relationship between each example and your main claim to make the progression more seamless.

Lexical Resource: Band 6.5

You use an adequate range of topic-related vocabulary, including “life expectancy,” “vaccines,” “artificial intelligence,” “scarcity,” and “adequate food or water.” These choices communicate the main ideas clearly, and some less common terms show an effort to discuss science and social priorities precisely. At times, though, wording is broad or repetitive: “made life easier,” “make people's lives better,” and “advancements” recur without much variation. A few collocations are also less natural, such as “yield little result” and “live their lives effectively.” More precise phrasing would help distinguish practical benefits from wider social impact. Aim to use varied, accurate expressions for improving wellbeing and to describe the consequences of scientific investment more specifically.

Grammatical Range and Accuracy: Band 7.0

You use a mix of simple and complex sentence forms, and many sentences are controlled accurately. For example, “These advancements have led to the prevention of diseases, improved treatment and increased life expectancy” uses a clear parallel structure, while “as they can communicate effectively and instantly” adds a subordinate clause appropriately. Punctuation and sentence boundaries are generally sound, and errors do not obstruct meaning. There are a few areas to refine: “such as huge investments in space technology that yield little result” has a slightly awkward relationship between the example and the clause that follows, and “not be limited to a select group, ignoring those suffering from poverty” leaves the subject of “ignoring” somewhat unclear. Recast such sentences so that modifiers and references attach unmistakably to the intended idea.
