While aspects such as religion, language, and available resources varied and were also essential to the settlement's culture and societal norms, the presence of a distinct government system offered the required governance and order needed for a community to thrive.

Regarding the predominant religion in Pennsylvania, it was founded by members of the Society of Friends, also known as Quakers. Therefore, the correct answer to the second question is A. Quakerism. This religious group played a central role in the establishment and development of the Pennsylvania colony, contributing to the colony's distinctive character and beliefs.

Describe how British trade with China triggered the opium war

Answers

The Opium War was an armed conflict between Britain and China in the years 1839-1842 and 1856-1860.

With the end of the Napoleonic Wars, all maritime trade turned to the East, but there was a problem: China still maintained some restrictions in relation to trade with foreign countries.

Great Britain, which in turn was going through the second Industrial Revolution, increasingly needed raw materials at low prices and a large consumer market to sell its products. And this is where China and India arouse great interest on the part of the British as they both had a large population, which would mean a large consumer market. India was open to any foreign business, and on the contrary China was very resistant, at least with regard to the purchase of European products, but selling its products to these interested countries, she did not think twice.

China was a major producer of silk, porcelain and tea, which was the product that aroused the greatest interest in the British. In 1720 they bought about 12,700 tonnes of tea from the Chinese, and in 1830 they bought around 360,000 tonnes, however the Chinese had no interest in European products, which brought very little profit to the British. Only one product aroused great interest in them and it was often he who made trade with China profitable. That product was Opium.

All of thes are found in a commond economy except

Answers

The correct answer is ownership of corporate stock

A command economy, also called a centralized economy, is an economic model that defends State control over the economy. This model became known after its application for more than 70 years in the extinct Soviet Union.

In the centralized economy, most of the companies that operate in the economy are state-owned, that is, they belong to the state. Contrary to what happens in the market economy, the law of supply and demand does not dictate the laws of commerce, the government makes decisions. Thus, a product that is missing does not suffer from the increase and, likewise, a product that is accumulated does not suffer any reduction.

Thus, the logics and strategies of the market follow the elaboration of plans. These plans, which in the Soviet Union were called "five-year plans", have the function of unraveling and solving the problems and weaknesses of the economy. Another objective is to contain unemployment, by expanding the productive sector.

With the planning of the economy, it would be possible to control the problem of income distribution, since everyone would have jobs and wages that would not be enough to accumulate, but that would allow the maintenance of living costs in society.

Wilson's 14 Points and America's entrance into the war

Explanation:

All countries during WW1 developed total warfare, which meant all resources were being placed into the war effort. This consisted of factories now developing weapons, human resources, and a stall on an adaptation of labour unions. After German stalemates in both of their wars - Russia and Germany the population was exhausted. America entering the war, due to Germany sinking civilian ships, essentially turned the tide once again (after the defeat of Russia) to the Allies forcing German leadership to surrender or face defeat. Yet Wilson's 14 points were dropped on battlefields and civilian area in Germany and Austria-Hungary which spread the false belief that Germany would face no repercussions for surrendering which convinced the German Population to want to surrender. The communist takeover in Russia and the split of Austria-Hungary occurred after the end of WW1

What do the list show about the financial position of France in 1786

Answers

France was bankrupt in 1786, they faced a financial crisis 1786-1788. This financial crisis resulted in the French Revolution.

French Revolution, which played a very important role in the foundations of society at that time and was also a dividing point in history, since it was this Revolution that started the Contemporary Age.

This event was also very important for other movements that happened afterwards, the ideals of the French Revolution influenced many movements around the world.

Final answer:

France's financial position in 1786 was precarious, leading directly to the conditions that sparked the French Revolution. Extensive debt from royal extravagance and support for the American Revolution, coupled with social inequalities, set the stage for widespread discontent and demand for change.

Explanation:

The financial position of France in 1786, as indicated by various historical accounts, was dire and significantly contributed to the conditions leading to the French Revolution. The opulent spending by Louis XIV on constructions like the Palace of Versailles, combined with the financial strain of supporting the American Revolution, pushed France towards bankruptcy. It was a time of significant economic crisis characterized by high taxes, growing public debt, and financial mismanagement which led to widespread poverty and discontent among the population. Additionally, social inequalities magnified the turmoil, with the First and Second Estates enjoying immense wealth and privileges at the expense of the Third Estate which bore the brunt of taxes and had little political power.

The situation was further aggravated by poor harvests and the country's involvement in costly wars, leaving the monarchy in a position where raising revenue through the Estates-General was seen as a last resort. This move, intended to address the fiscal crisis, ironically opened the door to revolutionary demands for a constitutional monarchy and equitable taxation, reflecting the populace's frustrations with the old regime's extravagance and financial irresponsibility. The widespread inequality, the hunger for a new constitution, and the eventual capture of the royal family by a mob are poignant examples of the intense dissatisfaction that pervaded French society on the eve of the Revolution.

How did Southern Conservatives view Reconstruction?

*20 points*

Answers

Many Southerners, particularly those on the Conservative side, did not agree with the ideals of the Reconstruction. During the Reconstruction, the government's main objective was to assimilate Black Africans and former slaves into mainstream American society, and ensure that their newly given rights were protected.

However, many Southerners disagreed with this, as it was opposed to their traditional way of life. They believed African American people to be inferior to them, and were scared to give up power. Therefore, this period saw a lot of conflict in the South, and led to the development of institutions such as segregation and Jim Crow laws.

Who was the enlightenment thinker Voltaire?

Answers

Answer:

he was a french writer and public activities who played a singular role in defining the eighteenth-century movement called the Enlightenment.

Final answer:

Voltaire, a key figure of the Enlightenment era, advocated for intrinsic rights and freedoms, and criticized the Catholic Church and monarchy. His works contributed to shaping the French Revolution and influenced political reforms by promoting religious tolerance, freedom of speech, and the separation of powers.

Explanation:Voltaire and the Enlightenment

François-Marie Arouet, more commonly known as Voltaire, was a central figure in the Enlightenment era, whose philosophies and writings challenged the traditional doctrines of his time. Voltaire was an especially vigorous advocate of intrinsic rights and freedoms. His sharp criticism was often directed towards the Catholic Church, aristocracy, and the French monarchy, advocating for religious toleration and freedom of speech. His notable works include the 'Treatise on Tolerance' and 'Republican Ideas', and he is most well-known for his satire, 'Candide', which lampooned both established religion and secular government.

Voltaire, along with other philosophers like Montesquieu and Jean-Jacques Rousseau, played a significant role in questioning and shaping the socio-political landscape of the time. Montesquieu introduced the idea of separation of powers within a government to prevent tyranny, a concept that heavily influenced the drafting of the United States Constitution.

The principles established by Enlightenment thinkers like Voltaire contributed to a spirit of intellectual investigation and social reform. This movement paved the way for questioning old ideas and advocating for laws and reforms based on reason, natural law, and scientific observation.

What was the legacy of John C. Fremont

Answers

The legacy that remain for John C.Fremont was the drawn of the map of the United States of America.He did maps of the places he went and the states,country near by.I hope this helps

The legacy of John C. Fremont is multifaceted, encompassing his roles as an explorer, military leader, and politician. As an explorer, Fremont led expeditions to map the American West in the mid-19th century, earning him the nickname  The Pathfinder.  

In the military realm, Fremont's legacy is more complex. During the Mexican-American War, he played a key role in the conquest of California. However, his tenure as a military governor was controversial due to his authoritarian rule and the execution of several Californios, which led to his court-martial.

As a politician, Fremont was the first presidential candidate of the newly formed Republican Party in 1856, although he lost to James Buchanan. His anti-slavery platform set the stage for the party's future successes. During the Civil War, Fremont's brief command in the West was marked by controversy, particularly his emancipation proclamation in Missouri, which was revoked by President Lincoln. This action highlighted the complexities of civil-military relations and emancipation policies during the war.

Fremont's legacy also includes his role in the development of the transcontinental railroad. As a major general, he was involved in the early surveys and advocacy for the railroad's construction, which would eventually link the East and West coasts of the United States.

Overall, John C. Fremont's legacy is characterized by his significant contributions to the exploration and mapping of the American West, his contentious military leadership, and his pioneering role in American politics, particularly in the context of the anti-slavery movement and the Republican Party's early years. His actions and policies had lasting impacts on the development and governance of the United States during a period of great change and expansion.
