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 prime purpose of science should be to better people’s lives. I agree with this statement. There are some other aims of science as well like advancements in agriculture, pestisides, insectisides, civil engineering, artificial intelligence. However, these are helpful in improving our lives indirectly. Some people also use science for their bad intensions like to destroy peace. These activities should be discouraged.

Healthcare systems are imporved due to the advanced research in medicine. People can have a better experience in medicine and surgery. Now a days complex surgeries are very common and successful. There are many preventive medicines available for the chronic conditions. For example, arthritis can be prevented by medicine. Neurosurgeries are performed with enhanced facilities. A number of genetic diseases can be prevented by genetics testings. Biotechnology has also an important role in healthcare. Specific lab testings are available almost every disease that helps in proper diagnosis and treatment plans.

Science has also aimed to improve other sectors of life such as civil engineering. People faced a lot of issues in housings, roads, buildings that were improved due to the technological advancements. Infrastructure has improved as compared to previous decades. For example, traffic has reduced due to the highways and signal-less roads.

On the other hand science can also be used for the bad purposes like creating technologies that are threat to the human race. For example, nuclear bombs have the potential to destroy a whole country. So such uses of science which are threat to humanity should be controlled by relevant authorities.

In conclusion, science should only be used for the betterment of human lives and its use in dangerous technologies should be strictly monitored.

Task Achievement / Task Response: Band 6.5

Your position is clear from the opening—“I agree”—and remains consistent in the conclusion. You address the central issue by explaining how medical research and engineering can improve lives, while acknowledging harmful uses such as nuclear weapons. These relevant examples show a sound response to the task. However, some points are asserted rather than fully explained: for instance, the claim that arthritis “can be prevented by medicine” is not clarified, and the engineering paragraph gives limited detail about how infrastructure improves people’s daily lives. The discussion of other scientific aims is also brief. To strengthen the response, explain the benefits and limitations of each example more precisely and connect them explicitly to your view that improving lives should be science’s foremost aim.

Coherence and Cohesion: Band 6.5

The essay has a clear overall structure: an introduction, paragraphs on healthcare and engineering, a counterpoint about dangerous technologies, and a conclusion. The progression from benefits to risks is easy to follow, and phrases such as “For example” help introduce supporting details. This gives the response a coherent arrangement. At times, however, connections between ideas are basic or slightly mechanical. The opening list of agriculture, pesticides, engineering, and artificial intelligence is not developed later as a connected line of reasoning, while “On the other hand” introduces a contrast without fully explaining how it qualifies the earlier argument. Some references, such as “these activities,” could be more specific. Use clearer links between each example and the main claim, and vary transitions to make the argument flow more naturally.

Lexical Resource: Band 6.0

You use an adequate range of topic vocabulary, including “preventive medicines,” “genetic diseases,” “biotechnology,” “infrastructure,” and “nuclear bombs.” These terms make the subject clear, and some choices show an attempt to use more specific language than everyday vocabulary. However, spelling and word-choice errors occur in several places, including “pestisides,” “imporved,” and “bad intensions.” Some collocations are also unnatural, such as “a better experience in medicine and surgery,” “genetics testings,” and “signal-less roads.” These do not prevent understanding, but they reduce precision and naturalness. Build accuracy by checking spelling and learning common word partnerships—for example, “medical treatment,” “genetic testing,” and “traffic congestion”—rather than translating phrases directly.

Grammatical Range and Accuracy: Band 6.0

You use both simple statements and some more developed structures, including “Although” is not needed here, but the sentence “There are some other aims of science as well like…” introduces a supporting list, and the essay includes examples and relative clauses such as “that helps in proper diagnosis and treatment plans.” Most ideas remain understandable, showing reasonable control of basic sentence forms. Some grammatical errors persist, however. For example, “Specific lab testings are available almost every disease” is missing a preposition, and “which are threat to humanity” needs an article. “Now a days complex surgeries are very common and successful” also needs punctuation after the introductory time phrase. Aim to produce more consistently accurate complex sentences, checking articles, prepositions, and sentence boundaries as you revise.
