When did the great leap forward take place?

The correct answer is - between 1958 and 1962.

The Great Leap Forward was an economic and social reform introduced by the Communist Party of China. This reform took place between the years of 1958 and 1962. The person standing behind it and that gave authorization for it was the infamous Chinese leader Mao Zedong.

The purpose of this reform was to industrialize China, thus boost its economy, as well as to strengthen the position and authority of Mao Zedong and the Communist Party of China as a whole.

The Great Leap Forward though did not lived up to the expectations. Instead of making China stronger, it actually made a bigger mess of its economy, including the most important sector, the agriculture. There was lack of food and the people were starving, though Mao Zedong was standing firm on it that it is a good and productive reform for the country in order to not admit that he made a huge mistake.

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.
