The line graph illustrates how many people visited three museums in a UK city over a ten-year period, from 2015 to 2025, measured in millions.

Overall, visitor numbers at all three museums fell sharply in 2021 before recovering strongly, and the National History Museum consistently attracted the largest audience except during this dip.

In 2015, the National History Museum welcomed 2.1 million visitors, comfortably ahead of the City Art Gallery, which had 1.5 million, and the Science Centre, which had the fewest visitors at just 0.9 million. Over the following four years, all three venues saw gradual growth, and by 2019 the National History Museum had climbed to 2.8 million visitors while the Science Centre had nearly doubled its 2015 total to 1.8 million.

This upward trend was interrupted in 2021, when visitor numbers plunged across the board, falling to between 0.6 and 1.2 million. From this low point, however, all three museums rebounded rapidly. By 2025, the National History Museum had reached its highest total of the decade, 3.4 million, and the Science Centre had overtaken the City Art Gallery to finish just behind it at 3.1 million, compared with the gallery's 2.0 million.

The bar chart compares the average weekly hours that five different age groups in the UK spent on their smartphones in 2015 and in 2025.

Overall, smartphone use increased across every age group over the ten-year period, and younger people consistently spent far more time on their phones each week than older age groups.

In 2015, 16 to 24 year olds spent an average of 18 hours per week on their smartphones, roughly six times as long as the over 55s, who used theirs for just 3 hours. Usage then declined steadily with age, with the 25 to 34 age group averaging 14 hours, the 35 to 44 group 10 hours, and the 45 to 54 group 6 hours.

By 2025, weekly smartphone use had risen in every category, though the gap between the youngest and oldest groups remained wide. The 16 to 24 age group recorded the sharpest rise, reaching 27 hours per week, an increase of 9 hours. The 25 to 34 and 35 to 44 groups also grew substantially, to 22 and 17 hours respectively. Although the over 55s still used their phones the least, their weekly average more than doubled, climbing from 3 to 7 hours.

The two pie charts compare how UK households distributed their spending across five categories in 1995 and in 2025.

Overall, housing became a significantly larger proportion of household budgets over the thirty-year period, while spending on food fell considerably. Transport and other costs remained relatively stable, whereas leisure spending rose.

In 1995, housing accounted for the largest share of expenditure at 28 percent, followed closely by food at 22 percent and transport at 18 percent. Leisure represented the smallest category, at just 12 percent, with the remaining 20 percent classified as other spending.

By 2025, housing had grown to represent over a third of household budgets, at 34 percent, making it by far the dominant category. In contrast, the proportion spent on food dropped to 15 percent, a fall of 7 percentage points, and transport declined slightly to 16 percent. Leisure spending, meanwhile, increased noticeably from 12 to 19 percent, overtaking transport to become the third largest category. Spending classified as other fell marginally, to 16 percent.

The two maps illustrate how the town of Riverbridge changed between 1990 and 2025.

Overall, the town underwent substantial development over the 35 year period, with a central park replaced by a shopping centre, new housing built, and a new road constructed, while the river, the school and the main road remained fixed features.

In 1990, Riverbridge was a relatively small town, situated along the River Aran, with a single main road running along its southern edge. At its centre lay a park, and to the south west stood a school. A small cluster of three houses had been built to the east of the park.

By 2025, the park at the centre of the town had been demolished and replaced by a shopping centre. A new road had also been constructed, running north to south and connecting the shopping centre directly to the main road. The area of housing to the east had expanded considerably, growing from three houses to six. The school and the river, however, remained unchanged in both size and location throughout this period.

The diagram illustrates the six stages involved in recycling a plastic bottle, from collection to the manufacture of new products.

Overall, the process is linear, beginning with the collection of used bottles from households and ending with the production of new plastic goods, and it involves both mechanical and industrial stages.

The process begins when used plastic bottles are collected from household recycling bins. These bottles are then transported by truck to a sorting facility, where, in the third stage, they are sorted according to plastic type and colour.

Once sorted, the bottles are washed before being shredded into small flakes, a step that also removes any remaining labels or caps. In the fifth stage, these flakes are melted down and formed into small pellets. Finally, in the sixth and last stage, the pellets are used as raw material to manufacture new plastic products, completing the process.
