Reading Passage 1

The Hidden Cost of Fast Fashion

AThe global clothing industry has become skilled at turning designs into inexpensive garments within a short period. New styles appear in shops and online throughout the year, encouraging consumers to treat clothing as a rapidly changing product rather than a durable possession. This model, commonly called fast fashion, depends on short production cycles, large volumes and prices low enough to make frequent purchases seem reasonable. Its success has widened access to fashionable clothing, but it has also raised questions about the environmental and social costs hidden behind low prices.

BThe environmental effects begin long before a garment reaches a shop. Producing fibres requires land, water, energy or chemicals, depending on the material. Cotton can require substantial irrigation in dry regions, while synthetic fibres are usually made from fossil fuels. Dyeing and finishing textiles can generate polluted wastewater if treatment is inadequate. Transport adds emissions, although the distance travelled is only one part of a garment's total impact; the materials and production processes may matter just as much.

CThe business model also influences how clothes are made. Brands compete to respond quickly to trends, placing pressure on suppliers to deliver large orders on tight schedules. Factories may face unpredictable changes in demand, and workers can experience long hours or insecure employment where labour protections are weak. Conditions differ between countries and factories, so it would be inaccurate to assume that every low-cost garment is produced under the same circumstances. Nevertheless, intense price competition can make it difficult for suppliers to invest in safer workplaces and higher wages unless buyers are willing to pay for those improvements.

DUnsold clothing creates another problem. Retailers must decide whether to discount stock, store it, send it to another market, recycle it or dispose of it. Recycling is often presented as a simple solution, but textile materials can be difficult to separate when garments contain blended fibres, stitching, buttons and coatings. Turning old clothing into new clothing of similar quality remains technically and economically challenging at scale. Some collected textiles are reused, but others are exported or become waste, and collection alone does not guarantee that a garment will be recycled.

EConsumers are often advised to make better choices, yet individual decisions take place within a system shaped by price, advertising, availability and convenience. Buying fewer items and wearing them for longer can reduce demand for new production. Repairing, swapping and purchasing second-hand clothing can also extend a garment's useful life. However, these options may be less accessible to people who have limited time, money or local services. Responsibility therefore cannot rest entirely on consumers; manufacturers, retailers and governments influence the options available.

FSome companies are experimenting with rental services, repair programmes and designs intended to last longer. These approaches can be useful, but their overall effect depends on how they operate. A rental system that involves frequent transport and intensive cleaning may not always have a lower impact than owning a garment and wearing it many times. Likewise, a durability claim is meaningful only if the product is actually used for longer. Evaluating such models requires evidence about total use, maintenance, transport and what happens at the end of a garment's life.

GPolicy can influence the industry through product standards, clearer information, extended producer responsibility and enforcement of labour rules. Yet rules must be designed carefully. A requirement that is easy for a large company to meet may overwhelm a small supplier, while a label that makes broad environmental claims without explaining its basis can confuse consumers. Reliable data and independent checks are needed to distinguish measurable improvements from marketing. The challenge is not simply to make clothing more expensive, but to ensure that prices more accurately reflect the resources and work involved.

HFast fashion illustrates a wider problem in modern consumption: the price paid at the checkout does not necessarily include every cost created during production and disposal. No single action can resolve the issue. Longer garment use, better manufacturing practices, credible regulation and more transparent supply chains can all contribute. The most useful question is not whether people should stop caring about fashion, but how the industry can meet that desire without treating resources, workers and discarded materials as if they were unlimited.

Can Urban Trees Cool a City?

ATrees are often promoted as a natural way to make cities more comfortable during hot weather. Their shade reduces the amount of solar energy reaching pavements, walls and people, while water released from leaves can cool the surrounding air through evaporation. These effects are valuable in places where roads and buildings absorb heat during the day and release it slowly at night. However, the cooling provided by trees varies with species, age, water availability, planting design and the shape of the surrounding streets.

BA tree's shade can make a large difference to the temperature of a surface even when the change in air temperature nearby is modest. This distinction matters because people experience heat in several ways. Direct sunlight, hot surrounding surfaces, wind, humidity and the body's ability to lose heat all affect comfort. A shaded pavement may therefore feel substantially cooler than an exposed one, even if a weather station several streets away records a similar air temperature.

CUrban trees also depend on water. In dry climates, newly planted trees may need irrigation until their roots become established. During severe drought, some species close the tiny openings in their leaves to conserve moisture, reducing the release of water vapour and therefore one source of cooling. If a city plants large numbers of thirsty trees without planning for water supply, the project may compete with other needs. Choosing species suited to local conditions and protecting soil around roots can improve survival.

DThe benefits are not distributed evenly across cities. Wealthier neighbourhoods often have more mature trees, private gardens and shaded streets, while heavily built-up districts may have little vegetation. These differences can intensify unequal exposure to heat. Planting programmes can help, but young trees provide less shade than mature ones and need years of care. A plan that counts only the number of trees planted may look successful even if many trees die or fail to reach maturity.

EStreet design can limit what trees achieve. Narrow pavements, underground pipes, overhead cables and dense building foundations leave little space for roots. Small pits may restrict growth, while compacted soil can prevent water and air from reaching roots. Trees also need enough room for their branches, and some locations may be unsuitable because of visibility requirements or the risk of falling branches. Urban forestry is consequently a matter of engineering and long-term maintenance as well as planting.

FResearchers use several methods to estimate the cooling effect of urban trees. They may compare temperatures in shaded and unshaded locations, use satellite images to measure surface heat, or run computer models that simulate different planting patterns. Each method answers a somewhat different question. Satellite measurements describe surface conditions rather than the exact temperature experienced by a person at street level, while a small field study may not represent the whole city. Combining methods can provide a more complete picture.

GTrees are not a replacement for every other heat adaptation. In some streets, reflective roofs, shaded bus stops, drinking-water points and changes to working hours may provide important protection. Trees can also interact with airflow: in a narrow street, dense crowns may reduce ventilation under certain conditions. This does not mean trees should be avoided, but it shows why planting plans need to be matched to local geometry and climate rather than applied as a universal formula.

HThe strongest urban tree programmes treat planting as a long-term public service. They select appropriate species, protect soil and water, monitor survival, and prioritise areas where heat exposure is greatest. They also consult residents, who may know which streets become dangerously hot or where maintenance has failed in the past. Counting trees is useful, but the ultimate measure is whether the urban environment becomes safer and more comfortable for the people who live and work there.

Reading Passage 3

Why Some Scientific Discoveries Take Time to Be Accepted

AA scientific idea does not become widely accepted simply because one researcher presents convincing evidence. Other specialists need opportunities to examine the methods, repeat important observations and consider alternative explanations. This process can take time, particularly when the claim challenges established theories or requires instruments that are not yet widely available. Delay does not always indicate that scientists are being unreasonable; sometimes the evidence is genuinely incomplete or difficult to evaluate.

BScientific communities rely on shared standards for collecting and interpreting evidence. A surprising result may attract attention, but researchers will ask whether the sample was large enough, whether measurements were reliable and whether other factors could explain the pattern. Independent replication is especially valuable because it can reveal errors that were missed by the original team. Even then, a failure to reproduce a result needs interpretation: the original finding may have been mistaken, or the effect may depend on conditions that were not repeated.

CEstablished theories influence how scientists interpret new observations. A theory is not merely a personal opinion; it is a framework supported by evidence that helps researchers connect many findings and make predictions. When a new observation appears to conflict with such a framework, researchers may first check the instruments, calculations and assumptions involved. This caution can protect science from premature conclusions, but it can also make a field slow to respond when a genuinely important anomaly persists.

DThe tools available at a particular time can determine which questions scientists are able to answer. A phenomenon may be noticed long before researchers can measure it accurately. Later advances in microscopy, computing or chemical analysis may make it possible to test explanations that previously remained speculative. New tools do not automatically prove an old idea, but they can turn a vague proposal into a precise question that can be investigated.

ECommunication and professional incentives also matter. Researchers need time and funding to conduct follow-up work, while journals may favour findings that appear novel or dramatic. Studies that confirm earlier results or report no clear effect can receive less attention, even though they may be essential for assessing reliability. If the scientific record over-represents striking discoveries, readers may gain an exaggerated impression of how quickly and neatly knowledge develops.

FThe acceptance of an idea is not always a simple contest between a lone genius and a stubborn establishment. Scientific debates involve evidence, methods, professional judgement, institutional structures and sometimes personal interests. Some researchers may defend a familiar approach because it has served them well, while others may favour a new proposal because it opens a promising research direction. These motives can influence discussion, but they do not determine whether a claim is ultimately supported by evidence.

GWhen evidence accumulates, scientific views can change. Several independent studies may produce consistent results, improved instruments may resolve earlier uncertainty, or a new theory may explain observations that the previous framework could not account for. Acceptance can still be uneven across different fields because researchers may rely on different data or face different practical constraints. Scientific agreement is therefore often gradual rather than a single event.

HThe slow acceptance of some discoveries shows why science should be understood as a method of correction rather than a list of permanent answers. Caution, criticism and replication can delay agreement, but they also help distinguish robust findings from attractive speculation. The goal is not to accept every new claim immediately or to defend every established view indefinitely. It is to change conclusions in proportion to the strength and consistency of the evidence.
