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 5.0)
Several people believe that the most crucial aim of science should be to improve mankind lives. Which is true to some extent not fully and reasons are mentioned below to support my opinion.
Firstly, it is clear that science is made to make the peoples life more easier and less complicated. Science has outdone itself in various aspects of life. For example, due to science and technology we are successful to travel way much quicker and faster through cars and airplanes as compared to our ancestors. Science is indeed a blessing. Many essential medicines and drugs are produced by science.
Adds on, many cures and treatments have been found due to science. It teaches us on how to conserve and maintain the enviroment in which we live. Nowadays, we can produce lab grown vegetables, meat and much more at a very reasonable cost.
Scientists are continously striving for new findings just to make the humans life more comfortable. But here's a catch that they also have many other duties for suppose, space exploration, enviromental research's and much more they just cannot continiously set their aim for improving people's life. I believe th knowledge that we know about our external space and plannets is all because of science and technology advancements.
Furthermore, all these facts about stars that there are billions of them in space and moon is cold and there is no gravity out there. Moving on, sun is the biggest star of our galaxy and it is super hot with temprature around 16000 degrees.
To sum up, science has made us rational and not fully but one of the most important aim of science should be to people's living condition.

Task Achievement / Task Response — Band 5.0
The response addresses the prompt by discussing whether science should primarily aim to improve people's lives, presenting a somewhat clear position that it is true to some extent. However, the development of ideas lacks depth and organisation in places. For instance, the transition into space exploration and astronomical facts in the later paragraphs feels disjointed and tangential to the core theme of human welfare. While the student attempts to weigh practical applications against theoretical pursuits like space research, the arguments remain somewhat superficial and lack extended elaboration. The conclusion attempts to summarise the viewpoint, but overall, the task is only partially satisfied because certain ideas are under-developed or veer off-topic, aligning the work with Band 5.
Coherence and Cohesion — Band 5.0
The text exhibits some organisational structure with basic paragraphing, but overall progression is hindered by abrupt transitions and disjointed sentences. For example, the opening paragraph features broken phrasing such as 'Which is true to some extent not fully and reasons are mentioned below'. Furthermore, cohesive devices are sometimes awkward, mechanical, or lacking, such as 'Adds on' instead of 'Additionally'. The grouping of ideas is loose, particularly in the shift from medical and environmental benefits to astronomical facts about stars and temperature, making the overall flow quite choppy and difficult to follow. This level of organisation corresponds to a Band 5 score.
Lexical Resource — Band 5.0
The vocabulary used is generally basic and repetitive, frequently relying on simple words like 'science', 'life', and 'make'. There are noticeable word choice and collocation errors, such as 'mankind lives' instead of 'human lives', 'peoples life more easier' instead of 'people's lives easier', and 'enviromental research's' containing both a spelling mistake and an incorrect pluralisation. Attempts at less common vocabulary are limited and often inaccurate, such as 'continously' (spelling error) and 'temprature' (spelling error). These lexical limitations and errors place the response firmly in the Band 5 category.
Grammatical Range and Accuracy — Band 5.0
The essay demonstrates a limited range of grammatical structures, relying heavily on simple sentences and basic coordination. When complex structures are attempted, they frequently contain errors, such as 'we are successful to travel way much quicker' instead of 'we are able to travel much more quickly'. There are frequent errors in punctuation, subject-verb agreement, and word forms, such as 'there is no gravity out there. Moving on, sun is the biggest star...' which disrupt the flow of reading. Although the meaning is usually retrievable despite the mistakes, the high frequency of grammatical inaccuracies restricts the score to a Band 5.
