The main debate between the North and South in the years leading up to the Civil War was over A. the South’s demand for higher tariffs on manufactured goods.

B.
the spread of slavery into the West.

C.
where the transcontinental railroad should be built.

D.
the North’s insistence that slavery must end in the South.

B.  the spread of slavery into the West.

Explanation:

It was an established fact in the years leading up to the Civil War that the South was pro-slavery and the North was Anti-slavery and so both sides had arguments about the spread of slavery into the western territories as those territories gained statehood.

The South wanted slavery to spread into the territories so that they would have more states which would give slavery more representation in Congress and therefore keep the practice going. The North wanted the territories to be free for the same reason.

Since 1865, the Ku Klux Klan has provided a vehicle for this kind of hatred in America, and its members have been responsible for atrocities that are difficult for most people to even imagine. Today, while the traditional Klan has declined, there are many other groups which go by a variety of names and symbols and are at least as dangerous as the KKK.

Some of them are teenagers who shave their heads and wear swastika tattoos and call themselves Skinheads; some of them are young men who wear camouflage fatigues and practice guerrilla warfare tactics; some of them are conservatively dressed professionals who publish journals filled with their bizarre beliefs — ideas which range from denying that the Nazi Holocaust ever happened to the contention that the U.S. federal government is an illegal body and that all governing power should rest with county sheriffs.

Despite their peculiarities, they all share the deep-seated hatred and resentment that has given life to the Klan and terrorized minorities and Jews in this country for more than a century.

The Klan itself has had three periods of significant strength in American history — in the late 19th century, in the 1920s, and during the 1950s and early 1960s when the civil rights movement was at its height. The Klan had resurgence again in the 1970s, but did not reach its past level of influence. Since then, the Klan has become just one element in a much broader spectrum of white supremacist activity.
