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)

It is widely argued that the main purpose of science should be to enhance people's lives. I strongly agree with this view, as societies expect to be benefited from scientific developments and discoveries. However, it may also bring negative effects for people.

One major reason for science to improve peples lives is the large investments in this sectors. Governments allocate a considerable amounnt of public resources to science, expecting positive results. For example, innovations in medicine, such as, vaccines, medical tratments and cutting-edge technology have succesfully contribute to society because they have increased life expectancy and improved public health. As a result, people live longer than ever before, while patients suffering from serious illnesses are more likely to be recovered from these medical conditions.

Science also has also contributed to advancements in techology. Without scientific research, many breakthroughs would not be possible, such as modern digital devices, which has transformed communication, education and entertainment. In this sense, science has changed people's lives in several ways.

Nevertheless, science is not without some drawbacks. One major concern is that during the process of new developments, scietists are exposed to different hazards, such as toxic substances and radioactive materials, which can threaten their lives. Scientists should also try several times before reaching an absolute innovation, which can take several years before being completely attained. Nevertheless, these disadvantages are part of sciense and may be overcomed as science continue to evolve.

In conclusion, although science can have some drawbacks, its contributions to society are significant, as it has improved porple's quality of life, while also making meaningful contributions to technology.

Task Achievement / Task Response — Band 6.5

The response addresses all parts of the prompt, maintaining a clear position throughout. The arguments regarding medical and technological advancements are relevant and well-supported with examples. However, the development of the counter-argument is slightly weak; the focus on hazards to scientists is less relevant to the core debate about the 'aim of science' than, for example, the ethical implications of weaponization or environmental damage. While the position is consistent, the depth of analysis could be improved by exploring the philosophical or societal implications of scientific goals more thoroughly. Overall, the response is well-structured and directly answers the prompt.

Coherence and Cohesion — Band 6.5

The essay is logically organized with a clear introduction, body paragraphs, and a conclusion. Cohesive devices such as 'One major reason', 'For example', 'In this sense', and 'Nevertheless' are used effectively to guide the reader through the argument. Paragraphing is used appropriately, with each paragraph focusing on a central theme. The progression of ideas is smooth, and referencing is generally clear. While the flow is logical, the transition between the benefits of science and the drawbacks could be slightly more sophisticated to enhance the overall coherence of the argument.

Lexical Resource — Band 5.5

The vocabulary is generally appropriate for the task, with some good collocations like 'cutting-edge technology', 'life expectancy', and 'public resources'. However, there are several spelling errors throughout the text, such as 'peples', 'amounnt', 'tratments', 'succesfully', 'scietists', 'sciense', and 'porple's'. These errors are frequent enough to be noticeable, although they do not impede communication. To reach a higher band, the student should aim for more consistent accuracy in spelling and attempt to incorporate a wider range of less common lexical items to demonstrate greater precision and sophistication.

Grammatical Range and Accuracy — Band 5.5

The essay demonstrates a mix of simple and complex sentence structures. There are several grammatical errors, such as 'societies expect to be benefited' (should be 'benefit from'), 'have succesfully contribute' (should be 'contributed'), 'patients... are more likely to be recovered' (should be 'recover'), and 'as science continue to evolve' (should be 'continues'). Additionally, there are minor punctuation issues, such as the unnecessary comma after 'such as'. While the meaning is always clear, the frequency of these errors prevents the essay from reaching a higher band. Focusing on subject-verb agreement and verb tense consistency would significantly improve the accuracy.
