Truth and lies How do you know when others are telling lies?

2) Why have many cities become so densely populated?
Because they are popular and they have many opportunities to offer to the citizens. For example, as I know Beijing which is located in China and Moscow Russian city and New York are a very crowded, very densely populated. Because all of people from different parts of the world come to those cities to find a better work and reside with decent commodities or even not so developed cities also tend to be very crowded and densely populated. Because they have relatively batter conditions than regions. For example, Tashkent also can be considered as densely populated area. Because it is more developed more than other region of my country. So people seek better opportunities and better like facilitators and come to those cities.
3) Is it possible that all of the population move to cities?
I wouldn't say that all of the rural people will move into the cities someday. But I think the rural places will alter to a city. Because even in a countryside nowadays we have certain construction sites which has high rise plans and in the future I think those skyscrapers will be in decent numbers in rural pleases too and make those areas cities too.
4) What changes do you think would make cities better places to live?
First of all lower level of noise. Because cities tend to have a high level of noise pollution. Because of the traffic and if the cities work a bit quieter. They would be much more pleasant to live.
5) Is it good for elderly people to live in large cities?
well yes why not. although there is high level of noise pollution. City buildings tend to be equipped with sound blocking and noise blocking windows. Therefore old people and other people in general are hardly ever distracted by them if they close their windows. and the comforts levels are so high in cities which make them very suitable for already people, already individuals. One example can be easy access to hot and cold water. Decent electricity and good supply of gas from which old age individuals have a better life.
