What is one difference between american government under the articles of confederation versus the constitution?

There are many differences between the Articles of Confederation and the US Constitution, but the biggest one is that under the Articles of Confederation the central government was weak and only had a unicameral legislature (which was the main reason why the Founding Fathers created the US Constitution), it didn't had any power to collect taxes or pay international debt, under the Articles of Confederation the US government looked weak on foreign affairs and could not deal with disputes between states because states were the ones who had all the power. Under the US Constitution there is a strong federal government which is divided by three branches: executive, bicameral legislature and judicial with a check and balances system that prevents an abuse of power; the federal government has the power to collect taxes and deal with foreign affairs and disputes between states.

well i cant say as there are no answers for me to choose from.

explanation:

sorry!

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.
