Task Achievement / Task Response: Band 3.0

The response identifies a position that appears to agree with the statement, saying science’s “very Significant aim” is to improve people’s lives. However, the task is addressed only minimally: there is no developed reason, supporting example, or consideration of how important this aim is compared with other scientific goals. The final sentence, “The most predominant factor is”, introduces an argument but leaves it unfinished. The response also does not meet the required minimum of 250 words, so there is not enough material to demonstrate a developed answer. To improve, state your degree of agreement clearly, then explain at least two relevant reasons and support them with specific examples, such as medical advances or clean-energy research.

Coherence and Cohesion: Band 4.0

There is a basic attempt to organise the response: an opening introduces the topic and position, and “To commence with” signals the start of a supporting point. This gives the reader a limited sense of direction. However, the progression stops almost immediately, and the final clause is incomplete, so the ideas are not arranged into a coherent argument. The opening also refers to “upcoming paragraphs,” but no developed paragraphs follow. Use a clear structure with an introduction, separate body paragraphs, and a conclusion. Within each body paragraph, present one main idea, explain it, and connect it to a relevant example; use linking expressions only where they clarify the relationship between ideas.

Lexical Resource: Band 4.5

The response attempts some topic-related and formal vocabulary, including “contributing factor,” “predominant,” and “shed light.” These choices show an effort to move beyond very basic wording. However, several expressions are inaccurate or unnatural, such as “science escalate by leaps and bounds” and “better live to people,” and capitalisation is inconsistent in “Significant” and “Life.” The limited amount of writing also provides little evidence of a flexible range. Aim for precise, natural collocations and check spelling and word forms. For example, describe science as “advancing rapidly” and say that it “improves people’s quality of life.”

Grammatical Range and Accuracy: Band 4.5

The response attempts both a complex opening sentence and a longer introductory structure, but control is uneven. The opening lacks an article before “undeniable fact,” and the sentence beginning “To commence with the contributing factor that why…” is not a complete, well-formed sentence. The final phrase, “The most predominant factor is,” is also unfinished and leaves the grammatical structure incomplete. Sentence boundaries and punctuation need attention, particularly the missing space after the full stop in “humans.The.” To improve, use complete sentences with a clear subject and verb, and check articles and clause structure. For instance: “It is undeniable that science has advanced rapidly and improved people’s lives.”
