The three pie charts show the main news sources for teenagers, young adults and old people.

Overall, the preferred news source varies greatly among the three age groups. Teenagers and young adults mainly get news from online sources, while old people tend to rely more on traditional media such as TV and printed newspapers.

For teenagers, online news sites are the most popular source, accounting for 52%. TV ranks second at 37%, while printed newspapers make up only 7%. Other sources are the least common at 4%.

Among young adults, the percentages are more balanced. TV is the most common source at 35%, followed closely by online news sites at 33%. Other sources account for 26%, whereas printed newspapers remain the least used at 6%.

In contrast, old people prefer traditional media. TV is the dominant source at 42%, and printed newspapers are also significant at 29%. Only 6% use online news sites, while 23% obtain news from other sources.

Problem 2: People leave the lights on and the water running in restrooms

One common problem in many schools is the waste of electricity and water in restrooms. Many students forget to turn off the lights or leave taps running after washing their hands. This situation leads to a large amount of water and electricity being wasted every day, which not only increases costs for the school but also harms the environment.

There are several possible solutions to this problem. First, the school should put up clear reminder signs near light switches and taps, such as “Please turn off the lights” or “Save water.” These signs can help raise students’ awareness and remind them to act responsibly. Second, the school can install automatic sensors for lights and water taps. With this system, lights will turn off automatically when no one is inside, and water will stop running when hands are removed. Finally, teachers should educate students about the importance of saving natural resources through lessons and school activities.

In conclusion, wasting electricity and water is a serious but solvable problem. With proper education, reminders, and modern equipment, schools can significantly reduce waste and protect the environment.

The line graph shows the urban and rural population in Vietnam from 1960 to 2020. Overall, the urban population increased while the rural population decreased.

In 1960, most Vietnamese people lived in rural areas. However, from 1960 to 1980, the percentage of the rural population fell slightly to 81 per cent. Then the figure remained stable for the next ten years. From 1990 to 2000, the proportion of the population living in rural areas continued to decrease gradually. In 2020, the rural population was only 63 per cent of the total population of Vietnam.

By contrast, the urban population rose throughout the same period. In 1960, the percentage of the city population was just around 15 per cent. The figure went up slightly in 1980 and remained stable until 1990 when less than 20 per cent of the population lived in urban areas. Since 1990, the proportion of the urban population has increased gradually and in 2020, it reached 37 per cent of the total population.
