Explain why the second schilling-louis fight was about more than boxing.

Joe Louis vs. Max Schmeling were two famous boxing matches, the first in 1936 and the second in 1938. Schmeling won the first confrontation by KO in the twelfth round, while in the second match, it was Louis who beat the opponent by technical KO in the first round. Although the two champions staged a remarkable show from a technical point of view, both of their fights are famous because they had significant social and political repercussions. As the greatest African American athlete of his time and most important black boxer since Jack Johnson, Louis represented the "pride of African Americans" in the 1930s. In addition, as a contrast between the United States of America and Nazi Germany, the two meetings symbolized the battle between democracy and totalitarianism. The performances offered by Louis in the two comparisons made him one of the first true African American national heroes of the United States.

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.
