The line chart depicts how many people took part in 4 kinds of sports, including basketball, tennis, badminton, and rugby over a 20-year period , starting from 1985.
Overall, there was a decrease in the number of people taking part in rugby, while the opposite trajectory can be observed in that of tennis, with tennis witnessing the most dramatic rise in the latter half of the period. In addition, the figures for badminton and rugby saw the same trend, with them remaining relatively stable. Notably, badminton consistently had the lowest number throughout the period.
About 250 participants were reported for rugby in 1985, with a mild decline over the subsequent decade to 200 people before plummeting to 100 in 2000 and hitting a trough of 50 in the last year of the period examined. In contrast, the number of people engaging in tennis started at 150, after which it increased considerably to 200 in the next 10 years and a final growth to more than 220 people in 2005.
As for the other sports, basketball started with 80 players in 1985, about 25 more than badminton. From this point, both the former and the latter exhibited the same trajectory, dropping to 78 and 49 people respectively in 1990. Nonetheless, over the next ten years, basketball participation increased slightly to around 90, while badminton numbers dropped to 45 in 1995. For the remainder of the period, both sports maintained steady participation levels, with their numbers remaining relatively constant until 2005.
