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 said that scientific research must be made for the betterment of individuals's lives. I agree to the statement becuase scientist have the knowledge which can be beneficial for human beings.

In contemporary time, science and technology is evolving. If we compare our current life to the past life, the change is quite evident. Back then, science had not made enough progress and people were living a difficult life. But now technology is used in every sector such as agriculture, medicine and teaching. If we look into more detail a hundered years ago, there were no advance pesticides that could effectively kill the harmful microbes affecting the crops. Also, fertilizers enriched with nutrients are available these days that increase the production of food to meet the needs of humans. In medicine, people relied mostly on alternative medicines such as herbal cures for fatal diseases, there were no effective ways to diagnose diseases but with the advancement in technology and science diagnostic machines have been invented such as X-rays and ultrasounds, multiple treatments are available according to the severity of the disease. For instance, a cancer patient can be now treated with chaemotherapy and sugery. Therefore, it is considered that scientists should aim for the improvement of living conditions of human beings and invent technology which would make their life easy.

However in certain situations, scientists are not well aware of the results of their discoveries and how the scientific knowledge will be used by people such as discovery of mining equipment lead to the discovery of weapons(guns). Scientists do research to add in their knowledge and draw results that might not be useful at the moment but in the future they will be used.

In conclusion,the primary aim of scientific knowledge should be to improve lives because they have the capability to make discoveries that would make human life easier.

AI examiner evaluation

Task Achievement / Task Response: Band 6.0

Your position is clear from the opening: you agree that science should improve people’s lives, and the conclusion returns to this view. The examples from agriculture and medicine are relevant and show how research can increase food production and support diagnosis and treatment. You also acknowledge a qualification: discoveries may have unforeseen uses, as with mining equipment and weapons. However, that counterpoint is brief and its connection to your main argument is not fully explained. Some claims, such as the broad contrast between life in the past and today, are asserted rather than supported. Develop each main idea with a clearer explanation of why it supports your position, and clarify whether unforeseen applications change the aim scientists should pursue.

Coherence and Cohesion: Band 6.0

The response has a recognisable overall structure: an introduction, a main paragraph supporting your view, a contrasting point, and a conclusion. Sequencing words such as “But now,” “For instance,” “However,” and “In conclusion” help readers follow the argument. The long central paragraph, though, combines agriculture, medicine, and the overall claim about scientists’ aims, so the progression becomes crowded. The contrast about weapons is also not clearly linked back to the question of what science’s most important aim should be. Use separate paragraphs for distinct examples and make the relationship between each example and your position explicit. More precise referencing would also help, particularly where “they” could refer to scientists, discoveries, or people.

Lexical Resource: Band 6.0

You use an adequate range of topic vocabulary, including “pesticides,” “fertilizers,” “diagnostic machines,” “severity,” and “scientific knowledge.” These terms help make the examples relevant and specific. There are also attempts at more formal phrasing, such as “the betterment of individuals’ lives” and “improvement of living conditions,” although some expressions are awkward or repetitive. Spelling errors such as “becuase,” “hundered,” “chaemotherapy,” and “sugery” show that written accuracy needs attention, while phrases such as “alternative medicines” and “make their life easy” could be more precise or natural. Build precision by checking spelling and choosing collocations that express the intended meaning clearly.

Grammatical Range and Accuracy: Band 5.5

You use both simple statements and longer complex sentences, including conditional phrasing (“If we compare our current life to the past life”) and clauses introduced by “that” and “which.” Meaning is generally understandable, but some grammatical errors recur. For example, “scientist have” has a subject–verb agreement problem, and “science and technology is evolving” also needs agreement. Articles and plurals are inconsistent in phrases such as “a difficult life” and “make their life easy,” while the sentence beginning “In medicine, people relied…” joins several ideas without clear sentence boundaries. Review agreement, articles, and punctuation, and divide long sentences so that each example is expressed accurately. This would improve control while preserving your range of structures.
