TV becomes the most popular source at 35%, followed closely by online news sites at 33%.
For old people, TV clearly dominates as the main news source, making up 42%. Printed newspapers are also widely used by this group, accounting for 29%. Meanwhile, other sources represent 23%.

People are beginning to use home robots more often in modern society. With the rapid development of technology, home robots are becoming familiar in many families. Although these machines are created to support humans, they have both advantages and disadvantages.

Using home robots has several advantages. Firstly, they help people save time by doing household chores such as cleaning, cooking, or taking care of simple daily tasks. This allows people to focus on more important work and enjoy their free time more. Moreover, home robots can improve living standards because they work continuously without feeling tired. In some situations, robots can also reduce stress, especially for people who are busy or under pressure.

However, there are some disadvantages to owning home robots. One clear drawback is their high cost, which means not everyone can afford them, but they are still very popular. Another problem is that people may become too dependent on robots, leading to laziness and weaker daily skills. In addition, home robots can cause privacy issues since they collect personal data.

In conclusion, home robots may make lives easier and happier, but they also bring certain problems that should not be ignored.

The line graph illustrates the percentage of urban and rural population in Viet Nam from 1960 to 2020. Overall, the proportion of the rural population experienced a significant decline, while the urban population saw a steady increase over the period.

In 1960, the vast majority of Vietnamese people lived in rural areas, accounting for 85% of the population. This figure decreased slightly to 81% in 1980 and 80% in 1990. Subsequently, the proportion of rural inhabitants fell more sharply, dropping to 70% in 2010 and reaching its lowest point of 63% in 2020.

By contrast, the urban population rose throughout the same period. Starting at a mere 15% in 1960, the percentage increased to 19% in 1980 and 20% in 1990. From 1990 onwards, the growth accelerated, reaching 30% in 2010 and finishing the period at 37% in 2020.

In many public restrooms, people leave the lights on and the water running after they finish using the facilities. This behavior leads to a serious waste of electricity and water. Over time, the unnecessary use of these resources increases utility costs and puts pressure on the environment, especially because clean water and energy are limited.

There are several reasons for this problem. First, some people are careless or in a hurry and forget to turn off taps and lights. Second, many restrooms do not have clear reminders to encourage responsible behavior. Finally, traditional taps and light switches rely completely on users, so waste happens easily.

To solve this problem, schools and public places should install automatic sensor lights and taps. These devices turn off by themselves when not in use, reducing waste effectively. In addition, posters and signs reminding people to save water and electricity should be placed in visible areas. Schools can also educate students about environmental protection through lessons and campaigns.

In conclusion, wasting water and electricity in restrooms is a small action with big consequences. With better equipment and awareness, this problem can be reduced significantly.
