Based on the excerpt, what are three reasons President Truman provides for the development and use of atomic bombs by the United States? Atomic bombs caused less destruction and death than other bombs. The Axis powers would have been unstoppable if they had developed the atomic bomb first. The atomic bombs needed to be tested in a real-world war scenario in Asia. The Americans used the bomb to end the war and minimize American casualties. The bombing was necessary to stop aggressive nations that endangered world peace.

1.) the Americans used the bomb to end the war and minimize American casualties.

2.) The atomic bombs needed to be tested

3.) They didn't want the war to go on any longer.

Out of the reasons you provided me, some of them didn't seem to fit the answer, I also don't have the excerpt that you read.

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.
