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 6.0)
I strongly agree that the most important aim of science should be to improve people's lives. Science has many purposes, but helping people is the most important.
Firstly, science improves health and saves lives. Medical science has invented medicines and vaccines for many dangerous diseases. For example, in the past many people died from COVID-19, but scientists made vaccines and saved millions of lives. Also, new machines in hospitals help doctors to find diseases early. So, science makes our life healthier and longer.
Secondly, science makes daily life easier and more comfortable. Technology, which comes from science, has given us mobile phones, electricity, and the internet. For instance, in my village Kunri, farmers use mobile phones to check weather and sell their crops online. In addition, science has improved transport. We can travel quickly by cars and airplanes. This saves our time and money.
Some people say science should also be used for space research or making weapons. However, I think these things are less important than people's lives. Space research is expensive and does not help poor people directly.
In conclusion, I agree that improving people's lives should be the main aim of science because it saves lives and makes our daily life more comfortable.

Task Achievement / Task Response: Band 5.5
The response clearly addresses the prompt by taking a strong position that the primary aim of science should be to improve human lives. The writer presents relevant main ideas, such as advancements in health, vaccines like those for COVID-19, and daily conveniences enabled by technology. Ideas are supported with examples, including a personal reference to farming practices in Kunri, and the response briefly acknowledges opposing views regarding space research and weapons. However, the response has a significant limitation: it contains only 206 words, falling well short of the 250-word minimum requirement. This under-length impacts the full development of ideas, preventing the essay from reaching a higher band. Consequently, the score reflects this restriction according to official assessment guidelines.
Coherence and Cohesion: Band 6.0
The essay demonstrates a logical overall organisation with a clear introduction, distinct body paragraphs introduced by sequencing phrases ('Firstly', 'Secondly', 'In addition'), and a concluding summary. Paragraphing is used appropriately to separate distinct points regarding health, daily life, and counterarguments. Cohesive devices are generally functional, although some transitions and referencing feel slightly mechanical or basic. Despite the brevity of the text, the progression of ideas is easy to follow from the thesis statement through to the final conclusion, ensuring that communication is smooth and straightforward throughout.
Lexical Resource: Band 5.5
The vocabulary used is adequate for the task, allowing the writer to communicate ideas clearly. Words such as 'vaccines', 'transport', 'electricity', and 'convenient' demonstrate a relevant lexical field related to science and daily life. The writer attempts some less common phrasing, such as 'dangerous diseases' and 'sell their crops online'. However, the range of vocabulary remains somewhat limited and repetitive, lacking the sophisticated lexical items and precise collocations expected at higher bands. Spelling and word choice are accurate and do not impede the reader's understanding.
Grammatical Range and Accuracy: Band 6.0
The essay displays a good mix of simple and complex sentence structures, including conditional or subordinate clauses such as 'Technology, which comes from science, has given us...' and 'Some people say science should also be used...'. There is good control of basic grammatical structures, and verb tenses are handled accurately when describing past events and general truths. While the range of structures is somewhat restricted due to the short length of the text, the sentences are generally clear and accurate, containing very few errors that do not impede communication.
