This passage refers to the issue of keeping standing armies in times of peace without the consent of legislatures.

B. works for a multinational corporation.
C. belongs to a marginalized social group.

Answers

A microfinance group (institution) would loan to an individual who was part of a marginalized social group.

The correct answer is option C. "belongs to a marginalized social group". Microfinance institutions are non-governmental organizations that could follow a bank scheme to provide financial support to the poor.

While at a banquet during his vice presidency, John C. Calhoun gave a toast: "To the Union. Next to our liberty, most dear." What does this quote reveal about why many South Carolinians wanted to secede from the Union? a) Some South Carolinians threatened to secede if liberty was not extended to the enslaved. b) South Carolinians in support of secession believed liberty was more important than maintaining the Union. c) The South Carolinians in support of secession wanted to leave the South and move to the North. d) John C. Calhoun encouraged many South Carolinians to support the Union, even if it meant the loss of liberty.

Answers

The right answer is the B) South Carolinians in support of secession believed liberty was more important than maintaining the Union. Calhoun had firmly opposed the so-called Tariff of Abominations (1828), since it was, he believed, detrimental to the Southern states and ultimately unconstitutional (since those states would have to pay more for imported goods). During this dinner, which took place in 1830, President Jackson toasted the preservation of the Union, and Calhoun responded with those famous words, which reflected his beliefs in a state's right to secede from the Union if the freedom and sovereignty of its citizens were not being respected.

Which factor most contributed to the United States becoming a more multicultural society during the late 1700s and early 1800s?

Answers

The factor which most contributes to the United States becoming a more multicultural society was the immigration. Immigrants were generally welcomed in the late 1700s and early 1800s. Despite of the fear that immigrants would alter United States culture and customs, the match between Europeans seeking opportunity and an America in need of people left the immigration door wide open. Between 1783 and 1820, about 250,000 immigrants came to America. After 1820, ships captains had to report on the immigrants they brought to the United States, and since then 67 million immigrants have been admitted to the United States contributing to a multiplicity of cultural, social and ideological beliefs.

Explain how Upton Sinclair’s book The Jungle embodied the Progressive belief that government intervention can solve social problems.

Answers

The Jungle was about things wrong with the meat packaging industry and proposed the government should regulate the meat industry; progressives believed government intervention could solve social problems as oppose to industrial capitalists believing in social Darwinism and laissez faire
Final answer:

Upton Sinclair's 'The Jungle' epitomized Progressive principles by showing how government regulations can address major societal ills, leading to significant reforms in the food industry with the passage of the Federal Meat Inspection Act and the Pure Food and Drug Act of 1906.

Explanation:

In 1906, Upton Sinclair's The Jungle emerged as a seminal muckraking novel, intimately associated with the Progressive Era's belief in government intervention for social reform. Sinclair aimed to expose the perilous conditions faced by workers and advocate for Socialism, yet his vivid depictions of the unsanitary practices in the meatpacking industry caught the public's attention far more. His work inadvertently focused consumer outrage on the contaminated beef hitting their plates, rather than the plight of the immigrant workers producing it.

Despite Sinclair's intentions, The Jungle greatly influenced public opinion and spurred Progressive reform. The government responded by passing the Federal Meat Inspection Act and the Pure Food and Drug Act in 1906, establishing sanitation guidelines and mandating food and drug labels to ensure consumer safety. These acts highlighted the Progressive belief that government regulation could tackle the significant social issues of the time, a fundamental departure from the laissez-faire attitude that previously prevailed.

Sinclair's lament that he aimed for the public's heart but "hit it in the stomach" underscores the unexpected trajectory of social change spawned by his novel. Despite the overreaching socialist agenda, the book's impact on food safety regulations exemplified the Progressive's approach of using government authority to correct capitalist excesses and protect the public welfare.

What impact did the enlightenment have on society

Answers

Enlightenment impacted society by introducing the idea that mankind could use reason to discover the laws of the world and the rights of mankind. These ideals affected all factions of society, from politics to religion.

Final answer:

The Enlightenment influenced the promotion of democratic principles, contributed to significant political revolutions, and altered the way societies understood authority, which has continued to shape modern governance and individual rights.

Explanation:

Impact of the Enlightenment on Society

The Enlightenment had a profound effect on society and shaped the course of history. It challenged the traditional authority of the monarchy and the church by promoting democratic principles and the idea of a social contract, which suggested that governments derive their authority from the consent of the governed, as proposed by philosophers like John Locke. This revolution in thinking influenced and helped engender the French Revolution as well as the Declaration of Independence of the Thirteen Colonies in America, laying the groundwork for modern democracy. Despite its emphasis on reason and progress, the Enlightenment also unintentionally enabled the development of military technologies leading to bloody wars, and did not prevent the ongoing enslavement or dispossession of marginalized groups.

Furthermore, the Enlightenment catalyzed economic development and the Industrial Revolution by favoring rationalism and an empirical approach to knowledge. However, this shift also led to increased societal inequalities and complex social problems. Still, the legacy of the Enlightenment continues to influence our notions of liberty, legal rights, and governance, proving its enduring importance.

                                    Bullying and how to defeat it

  Nowadays, all around the world this action is affecting people of all ages and just in some cases people try to eliminate this. This issue is consecuence of not teaching the people since they are kids, the good values that everybody should know in order to live in society pacefully.

 This matter sholuld be solved but not only by the people that is suffering it, but also the government or any other person that knows a case of bullying, eventhough it does not affect him or hre, should try his or her best to solve this problem and erradicate this issue. Specialists like psychologists and psychiatrists from every state, province or town that suffers this problem should interfere and teach people, from kids to adults, how to respect, help and make other people´s lifes happy instead of ruing them. If people could learn that if we all bring happines and respect to each other´s life, and that if someone is going through a hard situation we give him or her a hand, we would overcome a lot of hard situations easily and we would not be carrying with one heavy bag that makes our lifes harder and that bag is called bullying.

 Bullying should be penalized, if kids do it they should be taught how to respect their partners and if it is necessary private them from some benefits untill they learn. And in case of teenagers and adults, eventhough they should also be taugth how to respect their partners, if it is necessary they should be punished and pay a fine. At first it is going to be hard for familys to punishe their sons, brothers, uncles, cousins or any other member, but when they start to learn how to respect the others and their attitudes change, they will notice that it worth it was worth.

 Citizens and members of any society should inform the authorities if they know of any case of bullying in any environment because there are qualities of life that are being affected and if we want to make this world a better place we have to fight for what we want and teach good values to everybody who does not have them.

what is a common characteristic of utopianism, socialism, and communisum.

Answers

Final answer:

Utopianism, socialism, and communism share the characteristic of advocating for communal or collective ownership over private property, aiming to create a more equitable society.

Explanation:

A common characteristic of utopianism, socialism, and communism is the belief in the collective or communal ownership of property and goods, rather than private ownership. These ideologies share a pursuit of greater social equality and a vision for a society in which resources and wealth are distributed according to the needs of the community. This vision often includes the aspects of communal living, the abolition of private property, and the reorganization of society to prioritize cooperation and meet the needs of all its members, as opposed to a focus on individual wealth and competition. The utopian socialists of the nineteenth century, like Henri de Saint-Simon and Charles Fourier, as well as the founders of later socialist and communist thought, such as Karl Marx, all aspired to create a more equitable society by transforming economic and social structures

Land was inexpensive and even available, so that many Texans farmed or raised cattle on their own land instead of working for another person. The main activity in farmers lives was the growing of food crops, such as oats, sweet potatoes and wheat, which constituted a major part of their diet.
