Cooling the City (with data)
On hot summer afternoons, the centres of large cities can be several degrees warmer than the surrounding countryside. This "urban heat island" effect occurs because dark surfaces such as asphalt and roofing absorb sunlight and release it slowly as heat, while buildings trap warm air and reduce the cooling effect of wind. A lack of vegetation makes the problem worse: trees and plants cool the air by providing shade and releasing water vapour.
In a recent study, researchers measured the average afternoon surface temperature in July across four neighbourhoods of one city, alongside the percentage of each area covered by trees. Their results are summarised below.
Neighbourhood | Tree cover (%) | Average July afternoon surface temperature (°C)
Northgate | 8 | 41
Riverside | 15 | 38
Elm Park | 27 | 34
Hillcrest | 35 | 32
The researchers caution that tree cover is not the only factor: Riverside, for instance, is next to a large river, which may have cooled it independently. Nevertheless, they conclude that expanding urban tree cover is a promising strategy for reducing extreme heat, particularly in neighbourhoods where many residents lack air conditioning.
Question 2
Read "Cooling the City (with data)". Why do the researchers mention the river near Riverside?
- A. to show that rivers cause heat islands
- B. to explain why Riverside has no trees
- C. to acknowledge another factor that could affect the temperature
- D. to argue that trees are useless
The Four-Day Week: Promise and Pitfalls
In recent years, a growing number of companies have experimented with a four-day working week, in which employees work about 80 per cent of their usual hours for 100 per cent of their pay, on the condition that they maintain their output. Supporters argue that the model could transform working life. Critics warn that its benefits may be exaggerated.
The most widely reported trials have produced striking results. In one large study involving several dozen organisations, most companies chose to continue the four-day week after the trial ended. Employees reported less stress, better sleep and fewer days off sick, while company revenue remained broadly stable. For businesses struggling to recruit, the promise of an extra day off can be a powerful attraction.
Yet these findings come with important caveats. Companies that volunteer for such trials may already be enthusiastic about flexible working and well suited to it. Their success may not be representative of all workplaces. Moreover, many of the participating organisations were offices or creative businesses, where output is relatively easy to reorganise. In hospitals, schools or factories, where staff must be present to deliver a service, reducing hours without hiring more people may simply be impossible.
There are also questions about what happens in the long term. Early enthusiasm can fade, and the pressure to fit five days of work into four may eventually lead to longer, more intense working days, cancelling out the benefits to wellbeing.
None of this means the idea should be dismissed. It does suggest that the four-day week is less a universal solution than a tool that may suit some sectors far better than others. The challenge for policymakers is to learn from the trials without assuming that what worked for a marketing agency will work for an emergency ward.
Question 3
Read "The Four-Day Week: Promise and Pitfalls". Which finding from the trials is reported in paragraph 2?
- A. Employees reported more stress.
- B. All hospitals adopted the model.
- C. Most companies chose to keep the four-day week.
- D. Revenue doubled.
Beavers Come Home
Four hundred years after they were hunted to extinction in Britain, beavers are back. Small populations now live wild in parts of Scotland and England, and several other European countries have reintroduced them too.
Ecologists describe beavers as "ecosystem engineers". By building dams, they create ponds and wetlands that slow the flow of water, trap sediment and provide homes for insects, amphibians and birds. In one Devon study, the amount of water flowing downstream during heavy rain was noticeably lower below beaver dams than above them, suggesting that dams can help reduce flooding.
Not everyone is delighted. Some farmers report flooded fields and felled trees, and they worry about the cost. Their concerns are real, and schemes in some areas now compensate landowners or move beavers whose dams cause serious damage.
Supporters argue that the benefits outweigh the costs. Wetlands created by beavers can store water during droughts, improve water quality and attract visitors. Yet researchers caution that results vary from river to river, and long-term data are still limited.
What is clear is that the return of beavers forces us to ask a broader question: how much room are we willing to make for wild animals in a crowded country?
Question 4
Read "Beavers Come Home". Which detail best supports the idea that beaver dams may reduce flooding?
- A. beavers were hunted to extinction
- B. wetlands attract visitors
- C. farmers report felled trees
- D. less water flowed downstream during heavy rain below the dams than above them
Two Texts on Memory
TEXT 1
For much of the twentieth century, many people imagined memory as a kind of recording device. An experience, according to this view, was stored somewhere in the brain like a film on a shelf; remembering meant taking the film down and playing it again. Forgetting was simply the film fading with age. This model was appealing because it matched how memory often feels: vivid, detailed and certain.
TEXT 2
Decades of experiments have undermined the idea that memories are fixed recordings. In one well-known type of study, participants watch a video of a car accident and are later asked how fast the cars were going when they "smashed" or when they "hit" each other. Those who heard "smashed" not only gave higher speed estimates but were more likely, a week later, to report seeing broken glass – although there was none in the video. Such findings suggest that each act of remembering is partly an act of reconstruction, shaped by later information, expectation and language. A memory can feel certain and still be wrong.
Question 5
Read "Two Texts on Memory". In Text 2, what is the significance of participants reporting broken glass?
- A. It shows participants had poor eyesight.
- B. It shows the cars were travelling slowly.
- C. It shows that a word heard later altered their memory of the event.
- D. It proves the video showed broken glass.
Question 6
A scientist claims that a new fertiliser increases tomato yield without affecting taste. A: Plants with the fertiliser produced 30% more fruit, and taste-testers could not tell the tomatoes apart. B: The fertiliser is green. C: Tomatoes need sunlight. D: The plants with fertiliser were taller. Which finding would best support BOTH parts of the claim?
- A. A
- B. B
- C. C
- D. D
