For this 'To what extent' question, state your clear position (e.g., 'I largely agree' or 'I strongly disagree') in your introduction. While acknowledging the opposing viewpoint in a concession clause (e.g., 'While some argue that...'), immediately pivot to reinforce your primary stance, ensuring every body paragraph supports this main argument.

To support an 'agree' stance, cite the rapid advancements in cellular agriculture, exemplified by companies like Eat Just receiving approval for lab-grown chicken in Singapore. For clothing, mention the proliferation of high-quality synthetic and plant-based leathers, such as mushroom leather or recycled plastic fabrics. In medicine, discuss the shift towards plant-derived compounds and in-vitro testing, reducing reliance on animal-derived substances.

A common pitfall is failing to address the 'modern world' and 'necessity' aspects adequately, instead focusing solely on animal welfare without linking it to technological alternatives. Avoid this by explicitly discussing how contemporary innovations (e.g., biotechnology, material science) have rendered traditional animal product use less necessary, rather than just stating ethical concerns.

Employ a 'concession and refutation' strategy for opinion essays. Start a paragraph by briefly acknowledging a counter-argument (e.g., 'It could be argued that traditional medicines still rely on animal extracts...'). Then, immediately follow with a strong refutation or a more compelling argument supporting your main stance, using phrases like 'Nevertheless, advancements in synthetic biology demonstrate...' or 'However, this perspective overlooks the growing efficacy of...'

Examiners look for a nuanced discussion that goes beyond a simple 'yes' or 'no.' A band 8-9 answer will explore the complexities, perhaps acknowledging that while *some* uses remain, the *overall necessity* is diminishing due to innovation, demonstrating a sophisticated understanding of the topic and the 'extent' required by the prompt. Use precise academic language related to technology, ethics, and sustainability.
