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)

In the modern era, the importance of science is most limited to its aim of improvement of lifestyle of humans. This statement is the point of debate among various experts but has my support.

As far as my opinion is valued, the foremost cause of science should be the benefit of humankind and proposal of effective remedies to sort out the issues and problems plagueing human lifestyle. A compelling reason for this is the fact that developments in the field of science and technology by the scientists were meant to create convenience for people. For instance,the invention of light bulb by Thomas Edison was to enable humans to carry out their affairs without hindrance during the night as well as the dark periods. Another example is the invention of telegraphs which were intended to soothe long distance communications without interuption.

So this demonstrates that scientific inventions have always contributed and targeted to increase comfort and ease in the lives of general public.

While science has contributed to significant inventions, it has also been misused to tend to ulterior motives of individuals or conceited organisations. One instance which is worth of mentioning, is the invention of nuclear weapons including atomic bombs and missiles. These were invented in the disguise of self defence and security essentials but in reality, these weapons are the greatest misuse of scientific knowledge and has the potential to wipe out humanity from the face of the planet.

In conclusion, science has always worked wonders for those who worked for collective welfare and development but also proved to be the deadliest weapon of those who exploited it for their personal interests. It is quite inevitable for all people to understand the fact that science and technology is not itself good or bad but it is the usage of it that makes it so.

Task Achievement / Task Response: Band 6.5

Your position is clear: you support science primarily serving human welfare, while acknowledging that it can be misused. The examples of the light bulb, telegraphs and nuclear weapons are relevant and help address both the benefits and risks of scientific progress. This gives the response a solid, task-focused argument. However, the benefits are explained mainly through convenience, and the examples are asserted rather than explored in much detail; the discussion of how science improves lives could include areas such as medicine or public health. The final point that science itself is neutral is useful, but its relationship to your claim about science’s “most important aim” could be made more explicit. More balanced development and clearer links between examples and your position would strengthen the response.

Coherence and Cohesion: Band 6.5

The essay has a recognisable structure: an introduction states your position, the body paragraphs consider benefits and misuse, and the conclusion summarises the argument. Ideas generally progress in a logical order, and signposts such as “For instance,” “Another example,” and “In conclusion” help readers follow the discussion. At times, however, linking feels formulaic, and some references are not fully clear. For example, “So this demonstrates” refers broadly to the preceding examples, while the shift from scientific benefits to misuse could be connected more directly to your central argument. The opening sentence is also difficult to follow, which weakens the introduction’s flow. Use clearer topic sentences and more precise links between each example and the point it supports.

Lexical Resource: Band 6.0

You use a reasonable range of vocabulary for the topic, including “collective welfare,” “scientific knowledge,” “ulterior motives,” and “wipe out humanity.” These choices show an effort to use less common and topic-specific language, and the overall meaning remains clear. However, some expressions are inaccurate or unnatural, such as “importance of science is most limited to its aim,” “proposal of effective remedies,” and “soothe long distance communications.” There are also spelling errors, including “plageing” and “interuption.” Aim for precise, natural collocations rather than formal-sounding phrases that do not quite fit the meaning. Proofreading spelling and choosing simpler, more idiomatic wording would improve clarity and control.

Grammatical Range and Accuracy: Band 6.0

You attempt a mix of sentence forms, including complex clauses such as “While science has contributed to significant inventions, it has also been misused…” and a concluding contrast between science and its use. Meaning is generally understandable, but some grammatical errors remain. For example, “the issues and problems plagueing human lifestyle” lacks a clear grammatical connection between “problems” and “plagueing,” and “these weapons … has the potential” has a subject–verb agreement error. Articles and sentence construction also need attention in “the invention of light bulb” and the opening sentence, whose structure makes the intended meaning unclear. Review agreement, article use and clause construction, and check punctuation around introductory phrases. More consistently accurate complex sentences would make your argument easier to read.
