Family is a basic constituent of any nation. The well-being of the nation depends on the well-being of each family. A lot of factors make a family happy, and children are among of them. But how many children does a family need to be perfectly happy?
In my opinion, parents should have three children. I consider it to be the optimum number of kids. Firstly, in this case parents contribute to population growth in the country. The demographic depression is really the case of many countries. Secondly, the children grown not all alone are more sociable and less egoistic. Thirdly, a child from a big family has a better chance to succeed in life because his siblings are willing to help.
Transport has always played an important role in people's life. It's a way of travelling from one place to another.
However, a couple of centuries ago, there were only carts carried by horses and old-fashioned boats.Perhaps, the oldest type of transport is the water one. People constructed primitive boats for river navigation since the stone ages. The first land transport was presented by the carriages, which were later carried by domestic animals. The first animal-drawn vehicles were traced in Europe in the 4th millenniun BC.Rail transport appeared much later, to be precise nearly 500 years ago.
