How did the k-n act, and opposition to the act, change the political spectrum and
landscape in america?

PLEASE GIVE BRAINLESTS!

Backround:

The Kansas-Nebraska Act organized two new territories in the land acquired through the Louisiana Purchase, Kansas and Nebraska. The act established that in these territories, the principle of popular sovereignty would apply, meaning that the white residents of each territory would vote on whether to permit slavery when applying for statehood.

The Act repealed the Missouri Compromise of 1820, which drew the horizontal line of slavery across the West along the 36° 30' parallel, as both Kansas and Nebraska were north of this line. This reopened the question of slavery’s western expansion.

Furthermore, many in the South were growing resentful of the Missouri Compromise, which established the 36° 30' parallel as the geographical boundary of slavery. Slaveholders entrenched themselves in defense of their “way of life,” which depended on the ownership of slaves, while also claiming that prohibiting slavery’s expansion ran counter to basic American property rights. They now contended that the question should be decided by popular sovereignty, or allowing the white residents of a territory to decide whether it should permit slavery when it applied for statehood.

Meanwhile, some antislavery northerners wanted the West reserved for poor whites to seek opportunity. Abolitionists, too, were becoming more vocal in their support for the complete end of slavery.

Democratic leaders sought to bind these disparate ideologies together. Illinois Democratic senator Stephen Douglas believed he had found a solution—the Kansas-Nebraska bill—that would promote party unity and also appease Southerners who detested the Missouri Compromise line. The act created two territories: Kansas, directly west of Missouri; and Nebraska, west of Iowa. The act applied the principle of popular sovereignty. Since both territories fell above the 36° 30' line, the proposed bill would repeal the Missouri Compromise of 1820.

explanation:

just took the test

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.
