What does Lincoln mean when he says “the laws of the Union be faithfully executed in all the States?” The Confederacy could create its own laws if approved by Lincoln. All states could choose to form their own governments if they wanted. All states, even those that seceded, must obey the laws of the Union.

Because if all states don't abide by the law it not only makes America look weak but also leads other states to believe they don't have to follow the capitals laws which leads eventually to Civil war in this case.

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.

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.
