Answers

The correct answer is Chile

Like the population, Chilean agricultural activity is concentrated in the central part of the country, whose climate is Mediterranean. This allows the cultivation of cultures common to places with a Mediterranean climate, such as: grapes and olives, which serve as raw material for the production of wine and oil.

The Chilean subsoil is rich in mineral resources, especially in copper, considering that about 38% of the world's deposits are in the country. This fact results in the position of first place in the production of this ore on a world scale.

In the industrial sector, Chile concentrates its pole in the vicinity of its capital, and the country's main center, Santiago. Industrial production is generally linked to primary production, such as the food, textile and mineral processing industries.

Suppose the Dutch had kept New Netherlands. How might the lives of Africans there have been

#SPJ1

Final answer:

If the Dutch had kept New Netherlands, the lives of Africans might have been different with a focus on urban and trade-related slavery rather than plantation agriculture, in a society with economic opportunities, religious toleration, and cultural diversity. However, the institution of slavery would still have been harsh, with Africans facing severe oppression.

Explanation:

If the Dutch had maintained control over the New Netherlands, the lives of Africans there might have been different compared to the later British rule. Under the Dutch, there was a significant degree of religious toleration, and a variety of European and African immigrants contributed to a culturally diverse population. However, the Dutch still relied heavily on the importation of enslaved Africans due to labor shortages. With a thriving fur trade being more central to the economy than plantation agriculture, the nature of slavery in New Netherlands may have aligned more with urban and trade-related labor, potentially offering a different set of experiences and interactions for enslaved Africans compared to the plantation-centric slavery that developed under English control.

Economic opportunities and a degree of religious toleration that welcomed non-Dutch immigrants might have allowed for a more mixed society, though the institution of slavery was still fundamentally exploitative. Comparatively, the Dutch mode of colonization, which sometimes utilized systems comparable to slavery such as the forced apprenticeships of Khoisan children, could imply that had New Netherlands persisted, Africans there would have still endured severe oppression, albeit within a different socioeconomic context than the plantation slavery that was common in English territories.

An ongoing labor shortage meant that New Netherlands welcomed immigrants and tolerated religious plurality, including the small population of Jewish people. Enslaved Africans were part of the diverse tapestry due to the labor demands, but their lives might have been influenced by the particular needs and structure of the colony's economy and society.

Many white southerners feared economic difficulties if

Answers

Their slave ran off and they owed money for it

Many white southerners feared economic difficulties due to the changes brought by the Civil War, emancipation of slaves, and Reconstruction policies that were seen as threatening their agrarian lifestyle and economic interests, leading to various forms of resistance and social upheaval.

The question concerns the fear many white southerners had regarding potential economic difficulties during historical periods of significant economic and social change in the American South. Mainly, these fears were linked to the changes brought about by the Civil War, the end of slavery, and the various economic reforms proposed and at times implemented during and after Reconstruction. The economic model of the South, which was heavily reliant on agriculture and slavery, was at risk due to these changes. Emancipation of slaves, tariffs, and other economic policies were seen as threats to the southern way of life and potentially causing economic hardship for white southerners.

Reconstruction efforts attempted to redress the societal imbalances through measures that granted freedpeople citizenship rights. However, the response from white southerners was often one of obstruction, resorting to various means, including the formation of organized terrorist organizations like the Ku Klux Klan, political corruption, and economic exploitation, to maintain control and resist these changes.

Throughout these periods, economic fluctuations and the imposition of trade restrictions added to the tension. The rise and fall of commodity prices, such as tobacco, and the imposition of trade restrictions by England further exacerbated the economic struggles of white southerners. While the elite might have been shielded to some extent, the common white southerners faced economic hardship and became increasingly anxious about potential upheavals to their economic stability.

The United States, historically, has been influenced by both Alexander Hamilton and Thomas Jefferson's visions. Hamilton's emphasis on a strong federal government, fiscal policies and support for urban commercial development are apparent in the US's economic growth and its standing as a global economic power.

However, Jefferson's vision of a rural republic with a focus on agriculture and land-owning yeoman, underscore the value placed on individual rights and state's rights, which can also be seen in aspects of American governance and lifestyle. Ultimately, it's safe to say the US leaned towards a balanced fusion of both visions, using Hamilton's financial and economic strategies, along with Jefferson’s emphasis on individual and state’s rights.

Both Hamilton and Jefferson influenced the development of the U.S., with Hamilton's strong central government vision being particularly realized in financial strategies, and Jefferson's emphasis on states' rights shaping political thought. Over time, elements of each vision were adapted to create a balance between federal and state powers. This blend is evident in the country's balance of economic and political policies.

The development of the United States was influenced by both Alexander Hamilton and Thomas Jefferson, though aspects of each vision were adopted and adapted over time. Hamilton's idea of a strong central government has been largely realized, especially through his financial strategies, including the formation of a national bank and federal assumption of state debts. On the other hand, many of his aristocratic elements, such as his specific vision for the Electoral College, were repurposed or discarded.Jefferson’s emphasis on states’ rights and agrarianism also shaped the country, particularly during his presidency and that of his successor, James Madison. While Jefferson advocated for a limited federal government, the necessity of balancing state and federal powers became apparent during events like the Napoleonic Wars. The continuing evolution of the U.S. political landscape reflects the blending and conflict of Hamilton’s and Jefferson’s foundational ideas, resulting in a nation that values both strong federal oversight and state autonomy.

Final answer:

African Americans faced discrimination and de facto segregation in northern cities, limiting their access to jobs and housing, sometimes leading to race riots, while fostering segregated neighborhoods and business districts.

Explanation:

African Americans who moved to northern cities during the Great Migration still faced racial limitations due to pervasive discrimination and segregation in housing, employment, and education. Despite the absence of strict legal segregation as in the Jim Crow South, northern cities exhibited de facto segregation, wherein racism and prejudice caused African Americans to be treated unfairly and restricted their access to various opportunities. The influx of migrants competing for jobs and housing exacerbated tensions, leading sometimes to race riots and other forms of racial violence. These circumstances contributed to the formation of racially segregated neighborhoods with their own black-owned business districts and black cultural life.

Explain how the Ordinance of Nullification caused conflict between South Carolina and the United States.

Answers

The Nullification Convention met in 1832. The convention declared the tariffs of 1828 and 1832 unconstitutional and unenforceable within the state of South Carolina after February 1, 1833. Decision of forcefully collecting taxes caused conflict between South Carolina and the United States.

Explanation:

The Ordinance of Nullification was caused by the belief that the tariffs of 1828 and 1832 favored the North over the South and therefore violated the Constitution. This led to the protest and conflict in between South Carolina and United States.

The imposition of tariffs argued that the U.S. Constitution gave rights to the states to block the enforcement of a federal law. Congress passed the new negotiated tariff to South Carolina. The convention declared the tariffs of 1828 and 1832 unconstitutional and unenforceable within the state of South Carolina after February 1, 1833.

For Rousseau, man would be born good, but society would corrupt him. In the same way, man would be born free, but everywhere he would find himself chained by factors such as his own vanity, the result of the corruption of the heart. The individual would become a slave to his needs and those around him, which in a sense refers to a constant concern with the world of appearances, pride, the search for recognition and status. Even so, he believed that it would be possible to think of an ideal society, thus having its ideology reflected in the conception of the French Revolution at the end of the 18th century.

How did the Atlantic slave trade contribute to the history of slavery? (Paragraphs 2-3)
The buying and selling of slaves has a long history. Ancient Egypt and the Roman world rested upon a foundation of slavery. From the 10th through the 16th centuries, slave markets in areas bordering the Mediterranean Sea featured Christian Slavs from the Eastern Adriatic and the Black Sea, as well as those from Africa and the eastern Mediterranean. The Islamic world in North Africa and the Middle East drew millions of slaves through trade with sub-Saharan Africa. Eventually, Christian societies forbade the owning of slaves who practiced Christianity. Muslim societies did the same, banning the owning of slaves who were Muslim. That ban, however, did not apply to anyone who followed other beliefs. In addition, through the millennia,prisoners captured in war might find themselves enslaved and transported long distances to provide labor for their captors.


If slave ownership and the trade in slaves had a long history, the Atlantic slave trade that began in the middle of the 15th century represented a new stage. It was, as British historian Hugh Thomas wrote, a “commercial undertaking involving the carriage of millions of people, stretching over several hundred years, involving every maritime European nation, every Atlantic-facing African people (and some others), and every country of the Americas.” Indeed, it laid the basis for our modern world.
A. It made it so only Africans in America could be legally enslaved.

B.

It commercialized the slave trade and made it wide-spread.

C.

It hurt the slave trade by losing potential slaves at sea.

D.

It limited the slave trade to only European countries.

Answers

Answer:

b

Explanation:

Final answer:

The Atlantic slave trade contributed to the history of slavery by commercializing it and making it widespread. Starting in the 15th century, it expanded the scale and impact of slavery to include all maritime European nations, African people, and American countries. This significant shift in the trade and enslavement of people, particularly Africans, has had lasting ramifications that are still felt today.

Explanation:

The Atlantic slave trade made a significant contribution to the history of slavery. This commercial enterprise, which started in the 15th century, marked a new stage in the history of slavery. Unlike the limited trade and regional slavery practices that existed in places like Ancient Egypt and the Mediterranean, the Atlantic slave trade broadened the scale and impact of slavery. It involved every maritime European nation, every Atlantic-facing African people, and every country of the Americas.

The Atlantic slave trade commercialized the system of slavery and it was responsible for the transportation of millions of Africans across the Atlantic to the Americas. This trade had an enormous impact on Africa, the Americas, and Europe, shaping the future demographics and societies of these continents. The wide-scale movement and subjugation of Africans have affected racial dynamics and have left behind a legacy that still resonates in the modern world.
