Why is justice taney's argument ineffective?
read the passage from the opinion of the court in dred
scott v. sandford, written by justice taney.
he uses the freedom of african americans as evidence.
he uses a previous status of african americans as
evidence.
he uses the dissenting argument of the court as
evidence
he uses the ruling of the previous court as evidence.
the question then arises, whether the provisions of the
constitution, in relation to the personal rights and
privileges to which the citizen of a state should be entitled,
embraced the negro african race, at that time in this
country, or who might afterwards be imported, who had
then or should afterwards be made free in any state; and
to put it in the power of a single state to make him a
citizen of the united states, and endue him with the full
rights of citizenship in every other state without their
consent? does the constitution of the united states act
upon him whenever he shall be made free under the laws
of a state, and raised there to the rank of a citizen, and
immediately clothe him with all the privileges of a citizen in
every other state, and in its own courts?
the court thinks the affirmative of these propositions

He uses a previous status of African Americans as evidence.

Explanation:

This is the main reason why Justice Taney's argument is ineffective. In this passage, Justice Taney talks about the status of African Americans. The judge wants to establish what the status of African Americans is according to the Constitution, and from this, derive the rights and privileges that African Americans should enjoy. This is ineffective as it relies on a previous status of African Americans as evidence, instead of a present one.

the answer is expolration. hope this !

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.
