Answer:

3) There are means of transport that we will use to travel in the future such as flying car, underwater train, driverless car,...

4) Overpopulation causes a lot of problems for the community:

- The increase in population makes the roads become more narrow and more vehicles are on the road.

- It can make the number of accidents happening in the world increase because of the vehicles on the roads.

- More people will commit crimes because overpopulation makes people homeless and have to live in the slums.

The solution to solve these problems is: 

- The presidents should limit the number of children born from 1 to 3.

- Use public transport so that we help the environment and reduce the number of vehicles on the roads.

5) Talking about one of the best festivals that I attend, it will probably be Tet Holiday. It is celebrated according to the lunar calendar. People do various amounts of activities. People usually cook special food, make offerings,... I see that many children came out and get lucky money from their relatives and the elderly. They play many interesting games such as jump rope and more. That day I felt really comfortable and happy because families gathered together and talk. I will never forget these days for the rest of my life because they are wonderful.

Question 5: 

My favourite festival is summer vacation. Simply because it was a vacation after a year of hard study. Going back to the countryside with grandparents, playing and resting in the middle of the day with the sound of cicadas humming peacefully. Nothing more to say it's amzing.
