by dividing powers among the levels of government

Explanation:

Any powers not relegated to the federal government is thereby given to the state governments, and those are further split in between local governments. Also, relegated powers to the federal government was further split into three different branches, being the executive branch, the legislative branch, and the judicial branch.

Towards the beginning, the federal government barely handled anything, as everything was left up to each state to decide. However, later on foreign relations was relegated to the federal government, followed by taxations and raising of armies. It is worth noting, however, that the federal government continued to gain more power throughout the years.

first paragraph (and busy all the night ,with a silence deep and white )

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
