PLEASE I NEED IT SUMMED UP QUICK!! In this unit, you read about transitions of power and the formation of newly independent nations in Africa, Asia, the Americas, and the Middle East. Some of these transitions were peaceful, while others caused long-term instability. Why do you think some countries were more successful than others with political transitions? What do you think were the biggest challenges facing newly independent countries? Would it have been possible for leaders to prevent these problems before they happened? Why or why not?

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.
