Task Achievement / Task Response: Band 3.5

You state a relevant, partly qualified position: you agree “to some extent” that science should improve people’s lives, while also arguing that it must protect animals and the planet. This shows awareness of the question and gives a possible direction for an argument. However, the response addresses the task only partially: the first supporting point stops at “science must,” and neither side is explained or supported with a developed reason or example. The response also falls 150 words short of the required minimum, leaving the position and ideas substantially incomplete. To strengthen your answer, explain how science improves human life, then discuss why environmental and animal welfare should also matter, using specific examples and a clear conclusion.

Coherence and Cohesion: Band 4.0

There is a basic attempt to organise the response: an opening states your position, “the main reason” signals a supporting paragraph, and “however” introduces a qualification. These markers help the reader recognise the intended direction. However, the overall progression is incomplete because the supporting paragraph ends abruptly at “science must,” and the final paragraph introduces animals and plants without developing the connection to the earlier point. The short response also has no concluding summary. Build a complete sequence of introduction, developed supporting paragraphs, and conclusion; use each paragraph to explain one main idea and connect it clearly to your position. This would make the organisation more coherent rather than relying mainly on signposting words.

Lexical Resource: Band 5.0

You use some vocabulary relevant to the topic, including “objectives of science,” “harm,” “animals,” and “planet,” and the reader can identify your central concern. However, the range is limited, and several inaccurate word choices or forms make parts of the message difficult to interpret. For example, “develope people’s lives” is not a natural expression, while “vivant” and “importance presence” do not convey your intended meaning clearly. Spelling errors such as “experement” also reduce accuracy. Develop a more precise set of topic-related expressions, such as “improve quality of life,” “conduct experiments,” and “protect biodiversity,” and check that each word fits its grammatical and contextual role.

Grammatical Range and Accuracy: Band 5.0

You attempt both a complex opening sentence with “because” and a contrast introduced by “but,” as well as a separate sentence beginning “however.” This shows some effort to connect clauses rather than relying only on short statements. However, the range remains limited, and errors in sentence construction frequently make the meaning unclear. The opening joins several ideas awkwardly, and “but also without forget that it should take care also” is not a complete, well-formed clause. The unfinished sentence “the main reason why i support this view is that science must” further prevents the idea from being expressed. Practise writing complete sentences with clear subject–verb structures, then check clause connections and punctuation before adding more complex forms.
