Sample Response
For the past few centuries, there has been a significant advancement in medical sciencesciences. Experiments involving different animal speciesspanning over different animal species have resulted in important discoveries. SomeFew people believe that testingdoing testing on animals is cruel, while others argueother argues that these experiments should continue to benefit mankind. This essay will analyse both pros and cons of conducting trials on animals.
People favouring laboratory experiments on animals argue that it is the best way to research, analyse and observe effects of different medicines before testing them on human beings. Experiments conducted onover animal species have resulted in the development of vital medicines including vaccines, drugs and antibiotics. For instance, polio which was a widespread disease in the mid-nineties was developed after rigorous testing on mice and monkeys, unavailability of these experimental subjects would have left the world in an epidemic state. Moreover, animal testing helps medical students to acquireseek the required knowledge and advance researchadvance in the research domain. Researchers also aim to minimise the suffering that animalsanimal experience.
On the other hand, trials and experiments on animals are cruel and we have no moral right to take away their lives for the sake of our research work. Their existence and ecosystem should be respected. There are many alternativesalternates available to perform scientific research. In many countries, cosmetics testing on animalstesting for the cosmetic industry on animal race isin now prohibited. Moreover, experiments on animal species might not give us the same resultsresult as they have different anatomies and biological systemsdifferent anatomy and biological system than human beings.
To conclude, the points above providethe above provide solid arguments highlightingin highlighting merits and demerits of doing experiments on animals. In my opinion, the benefits outweigh the disadvantages, but research and evaluation should be done in a controlled way. The government should also set up strict policies and regulationsregulation which should limit the use of animals as experimental subjectskeep the animal as an experimental subject to critical research purposes onlyin critical research purpose only.
Why this response received Band 6.5
The response’s strongest feature is its clear, balanced structure: it explains benefits and ethical objections before giving a definite, qualified conclusion. Its main limitation is imprecision, both in the factual example about polio and in recurrent awkward word choices and grammar. The highest-priority improvement is to develop each argument with accurate evidence while proofreading agreement, articles, and sentence boundaries.
IELTS Writing Criteria Scores
Task Response
The response addresses both sides and states a clear position with relevant support, although some development is uneven and the polio example is factually confused.
Use one accurate, fully explained example for each side and link it explicitly to the final judgement.
Coherence and Cohesion
The four-paragraph structure and contrast between viewpoints create clear progression, but some long sentences and mechanical links weaken the flow.
Break overloaded sentences into clearer units and use referencing to connect supporting details more naturally.
Lexical Resource
The response uses a sufficient range of topic vocabulary, but frequent collocation and word-form problems reduce precision.
Replace awkward combinations such as laboratory experiments conducted over animals with conventional, precise academic phrasing.
Grammatical Range and Accuracy
A mix of simple and complex structures communicates the argument clearly, despite recurring agreement, article, plural, and sentence-boundary errors.
Proofread systematically for subject–verb agreement and noun forms, then separate comma-spliced independent clauses.
