IELTS Academic Reading — Practice Test 1

For most of the twentieth century, buying second-hand clothes carried a stigma. It signalled that one could not afford new garments, and the trade was largely confined to charity shops and street markets. Over the past fifteen years, that perception has been turned on its head. Resale — the buying and selling of previously owned clothing — has become one of the fastest-growing segments of the fashion market, and several analysts now expect it to outpace the sale of new clothes within a decade.

Two forces, pulling in the same direction, explain the shift. The first is economic. A generation that came of age after the financial crisis of 2008 has been more cautious with money and more comfortable with the idea that ownership need not be permanent. The second is environmental. The fashion industry is a heavy consumer of water and a significant source of carbon emissions and textile waste, and younger buyers in particular have grown wary of 'fast fashion' — cheap garments designed to be worn a few times and discarded. Buying used clothing, the argument runs, extends the life of a garment and keeps it out of landfill.

What truly accelerated the trade, however, was technology. Online platforms removed the friction that had always limited second-hand selling. Where a seller once had to stand at a market stall or hand goods to a charity, an app now lets anyone photograph a jacket, list it and reach buyers anywhere in the country within minutes. Some platforms specialise in authenticating luxury items, charging a commission in return for guaranteeing that a designer handbag is genuine; others simply connect individual buyers and sellers and take a smaller cut. The result is a market that is both larger and more trusted than the informal trade it replaced.

Established brands watched this growth with a mixture of alarm and opportunity. At first, many feared that a thriving resale market would cannibalise sales of new goods: why buy this season's coat when last season's is available, barely worn, at half the price? Increasingly, though, brands have chosen to participate. Several now run their own 'take-back' schemes, accepting used items in exchange for store credit and reselling them under their own name. This lets a company capture revenue from a garment twice, burnish its environmental image, and keep the customer within its own ecosystem rather than losing them to an independent platform.

Yet the environmental case for resale is less straightforward than its advocates suggest. Critics point out that a lively second-hand market may, paradoxically, encourage more consumption rather than less. If buyers know they can recoup part of the cost by reselling, they may feel freer to buy in the first place, treating their wardrobes as something to be constantly refreshed. Economists call this a 'rebound effect': a practice that is efficient in isolation can increase total consumption once behaviour adjusts. The benefit of keeping one garment in use is real, but it can be cancelled out if it simply funds the purchase of two more.

There is also the awkward question of what happens to clothing that no one wants to buy. A large share of donated and traded garments is never resold locally; instead it is baled and shipped abroad, often to countries in Africa and South Asia. There, the influx can undercut local textile producers and, when the garments are finally worn out, create a waste-disposal burden that the exporting countries have effectively passed on. The tidy image of a circular economy, in which every garment finds a new owner, obscures a messier reality.

None of this means the resale boom is a mirage. It has genuinely changed how millions of people think about clothing, and it has made durability and reuse fashionable rather than shameful — a cultural shift that may matter more, in the long run, than any single transaction. But its champions would do well to be honest about its limits. Selling a garment a second time is better than throwing it away; it is not, on its own, a solution to the industry's appetite for resources.

Science has grown accustomed to explaining the mind in terms of the brain. We can say, with increasing precision, which networks of neurons fire when a person recognises a face, recalls a name or feels afraid; we can predict, from a pattern of activity, what someone is likely to report seeing. These are formidable achievements. Yet a stubborn gap remains between such explanations and the thing they are meant to explain. Knowing which circuits are active when you see red tells us nothing, it seems, about why there is something it is like to see red at all — why the process is accompanied by an inner experience rather than proceeding, as it were, in the dark.

The philosopher David Chalmers gave this difficulty its modern name in 1995, distinguishing the 'easy' problems of consciousness from the 'hard' one. The easy problems — how the brain integrates information, focuses attention or controls behaviour — are easy not because they are simple but because we know what an answer would look like: a mechanism, described in physical terms, that performs the function. The hard problem is different in kind. Even a complete account of every mechanism, Chalmers argued, would leave untouched the question of why any of it is experienced. It is conceivable, he suggested, that a creature could be identical to us in every physical respect and yet have no inner life whatever — a so-called philosophical zombie. If such a being is even coherent to imagine, then experience is not simply identical to physical function.

Not everyone accepts that the problem is genuine. To one influential school of thought, the sense of an unbridgeable gap is an illusion generated by the very mind that reports it. On this view, when future neuroscience has explained every capacity associated with consciousness — every judgement, every report, every reaction — there will simply be nothing left over that needs explaining. The intuition that something has been missed, these thinkers argue, is a cognitive trick, not a datum to be respected. The philosopher Daniel Dennett, the best known advocate of this position, has long maintained that the apparent mystery dissolves once we stop trusting our first-person impressions as though they were direct reports of inner facts.

Between outright denial and Chalmers's dualism lie a range of intermediate proposals. Some researchers look to physics itself, suggesting that experience might be a fundamental feature of the universe, as basic as mass or charge, present in some rudimentary form wherever information is processed. This idea, panpsychism, was long dismissed as mystical but has attracted renewed, if cautious, interest, precisely because it refuses to treat consciousness as something that must emerge, unexplained, from unconscious matter. Its critics reply that it merely relabels the problem: saying that experience is everywhere does not explain how the simple experiences of particles could combine into the rich, unified consciousness of a person — the so-called combination problem.

A more empirically minded camp brackets these metaphysical disputes and asks a narrower question: which physical processes are reliably associated with conscious experience, whatever its ultimate nature? The search for such 'neural correlates of consciousness' has produced competing theories. One holds that a mental state becomes conscious when its information is broadcast widely across the brain, made available to many systems at once; another locates consciousness in the degree to which a system's parts are causally integrated, proposing that experience corresponds to a specific, in principle measurable, property of a network. Each theory has its evidence and its difficulties, and no consensus has emerged as to which, if either, is correct.

The stakes of the debate reach beyond the seminar room. If consciousness is a matter of integrated information, some argue, then a sufficiently complex machine might possess it, with consequences we are unprepared to face; if it depends on features peculiar to living brains, no computer, however capable, would ever be more than an unfeeling simulation. The same uncertainty shadows medicine, where clinicians must judge whether a patient who cannot respond is nonetheless aware, and ethics, where the question of which creatures can suffer turns on which of them have experiences at all.

What unites these otherwise incompatible positions is a shared suspicion that the tools inherited from the rest of science may not, as they stand, be adequate to the task. The physical sciences advanced by setting aside the observer and describing the world in objective, third-person terms. Consciousness is the one phenomenon that cannot be so described without discarding the very feature that makes it puzzling. Whether this means we need new concepts, a new physics, or merely more patience is itself disputed — which is perhaps the surest sign of how far we still are from an answer.
