Answer and Explanation:
1. The capital of Brazil was changed on April 21, 1960 by the president Jucelino Kubitschek, who built a city, called Brazilia, to become the country's federal capital instead of Rio de Janeiro, which was the old capital. He did this because Rio de Janeiro is very close to the ocean and he believed that it left the capital vulnerable to marine attacks, for this reason, he decided to move the capital to a more central region of the country, where it would be more protected.
2. Internal migration in Brazil occurs mainly due to economic factors, where citizens from the poorest states and with the worst living conditions (northeastern states) migrate to the producing centers of the country, which are the southeastern states, mainly São Paulo. Internal migration in China also has the economic condition as its main reason, however the Chinese are constantly migrating to the country's capital and need to submit to a series of laws and guidelines, while in Brazil, this process is done without any type of legislation or restriction.
Answer with Explanation:
<em>Genetics' influence on the happiness</em> of a person has long been studied. Some people say that the genes of a person affects the person's mood. For example, "5-HTTLPR" is a gene that is regarded to be connected to depression. This is why it is called<u> "the depression gene."</u> It is also associated with sleep disorders like "insomnia." When someone has trouble sleeping, it disrupts his way of life thereby affecting his happiness.
On the contrary, the genes exhibit themselves according to external environments. This is also one reason why a person's happiness may also be determined by his<em> success in life, material possession, relationships with people and so on.</em> So, a person's situation in life partly influences his happiness.
