1. Although the Lusitania was sunk in 1915, and it angered many Americans, the government refused to go to war. Why do you think the country remained out of the war for two more years?

Answers

Final answer:

The U.S. remained neutral after the Lusitania's sinking due to isolationist policies and the unpreparedness of the American military; however, Germany's renewal of unrestricted submarine warfare and provocative actions ultimately pushed the U.S. to join the war in 1917.

Explanation:

Although the sinking of the Lusitania by a German U-boat in 1915 enraged many Americans, the U.S. remained neutral for two more years due to a variety of reasons. The American public and government held a strong isolationist sentiment, viewing the conflict as a European affair that the U.S. should avoid. President Woodrow Wilson was re-elected in 1916 with the campaign slogan 'He kept us out of war', signaling popular support for this stance. Furthermore, despite the outrage over the Lusitania, the American military needed time to prepare for potential involvement. It wasn't until 1917, when Germany resumed unrestricted submarine warfare and made several diplomatic missteps, such as the Zimmermann Telegram, that the sentiment shifted, leading to U.S. entry into the war.

Final answer:

The United States remained out of the war for two more years due to isolationist sentiment, economic ties, and a gradual shift in public opinion.

Explanation:

The United States remained out of the war for two more years after the sinking of the Lusitania for several reasons:

Isolationist sentiment: Many Americans believed that the war in Europe was not their concern and that American troops should not be involved.Economic ties: Despite their neutrality, the United States provided military and civilian supplies to the British, as well as loans to support the British economy.Gradual shift in public opinion: The sinking of the Lusitania, along with subsequent attacks on American civilian vessels, shifted public sentiment and eventually led to the U.S. declaring war on Germany in 1917.

Which of the following best describes how Hammurabi’s Code and the Jewish Ten Commandments are similar?
A. They were written to retell the myths for each society.
B. They were written to be codes of laws for early civilizations.
C. They were written by people who practiced the same religion.
D. They were written to tell future generations about each society.

Answers

B. They were written to be codes of laws for early civilizations. 

Answer:    B. They were written to be codes of laws for early civilizations.

Explanation:  Both laws provide a set of rules and duties that people have to respect and fulfill in accordance with the attainment of an ethical and legal standard of living. Hammurabi's code is the Babylonian legal framework for the inhabitants of ancient Mesopotamia, and it can be considered in addition to being a legal, also religious law, because it is a civilization period when kings were "chosen" by god or gods. Ten Commandments are the primary religious law with all norms of conduct and obligations regulating the legal framework, that is, the laws that came from the law of God.

The Hammurabi's code is one of the oldest laws in the world, and is considered the basis or starting point for the development of Jewish, Christian and Islamic laws.

Another similarity is that, for example, in the Hammurabi's code, social classes are clearly divided, starting with nobility, through free people to slaves, therefore there is a social ranking, while according to the Ten Commandments from which a set of books on laws and religious customs has been developed, duties are clearly divided between tribes of Israel.

When Machiavelli wrote The Prince in 1513, he faced a lot of criticism. What were the key ideas of The Prince, and how did these ideas influence European rulers?

Answers

The key ideas of The Prince were to instruct on how to be a strong, dependent leader. The text suggested that Italy needed a rather ruthless leader to maintain a safe state.Machiavelli received a great amount of criticism for dismissing popular opinions in politics, sticking with his idea of a cruel leader. However, this did influence European rulers to begin thinking in a more realistic way, determining what's likely to come of a human rather than simply hoping for good.

The Prince is noteworthy in the history of political thinking because it proposes a purposeful approach to problems. Because he believed that leadership could not transform the world, he offered a governance structure focused on making the most of what was available.

Why did Machiavelli write The Prince?

Machiavelli's goal in writing 'The Prince' was twofold: first, to demonstrate to a ruler or would-be ruler how to maintain a safe and prosperous state in the midst of the political turbulence of early 16th century Italy, and second, to redeem himself in the eyes of Florence's ruler, Lorenzo de Medici.

The Prince's overarching subject is that princely goals, such as glory and survival, can justify the employment of immoral means to attain such goals. According to Machiavelli's correspondence, a version with the Latin title De Principatibus was issued in 1513.

how did genghis Khan succeed as a conqueror ?

Answers

He was a great military leader and would often do things the enemy did not expect. Also, the Mongols were very skilled horsemen and one of their inventions, stirrups, allowed them to stand up and turn around while fighting on horseback.

Genghis Khan was one of the most successful conquerors in world history. He united the nomadic Mongol tribes into a powerful empire and established the modern nation of Mongolia.

Genghis Khan's success as a conqueror can be attributed to three things: his use of superior military tactics, his relentless ambition and determination, and his ability to exploit political fragmentation among his enemies. Khan’s military prowess included mobility, strong discipline among the troops, advances in war tactics and weapons technology, and an adaptive approach that often outmaneuvered his opponents.

His ambition was demonstrated through his relentlessness in pursuing wars and expanding his empire, as well as his willingness to take risks when he needed to. His political acumen was evident in how he used political divisions and rivalries among his foes to his advantage.

Khan’s remarkable success in conquering and uniting a large number of tribes under one banner is a clear testament to his genius, ambition, and military and political strengths as a leader.

What event resulted in the political weakening of patriarchy in china?

Answers

Following the collapse of the Han Dynasty, several events paved way for the weakening of patriarchy in China. In the political sphere, weakening of patriarchy came about because of the invasion of the pastoral and nomadic people in northern China and more importantly, the rise into power of Empress Wu, who is the first and only woman to ever rule China. The nomadic culture, which was less restrictive to women, began to spread and influence the people of China, and the reign of Empress Wu further empowered women, leading to the weakening of patriarchy.

Final answer:

The Communist Revolution in China (1945-1952) and subsequent establishment of the PRC in 1949 under Mao Zedong led to the political weakening of patriarchy, as it involved the implementation of reforms promoting gender equality and challenging traditional patriarchal norms.

Explanation:

One significant event leading to the political weakening of patriarchy in China was the Communist Revolution (1945-1952). Following the establishment of the People's Republic of China (PRC) in 1949, Mao Zedong and the Chinese Communist Party (CCP) began implementing reforms, including gender equality, that challenged traditional patriarchal structures. Women's position in society took a turn, as Mao pledged equal rights between sexes and enacted policies that allowed women to own land, receive education, and take on leadership roles, which were radical departures from the patriarchal norms entrenched by Confucianism.

Final answer:

Americans at the turn of the twentieth century had mixed feelings about urban life, embracing the cultural vibrancy and economic opportunities while also confronting challenges like poverty and social tension. Urbanization contributed to the melting pot of American society but also led to inequalities and prejudice.

Explanation:

In urban life at the turn of the twentieth century, Americans experienced a mix of both excitement and apprehension. The positives of urbanization included vibrant cultural attractions such as museums, theaters, and the City Beautiful movement, with its emphasis on public green spaces and improved urban design, and the opportunities for economic growth through advances in technology and transportation. However, alongside these developments came challenges such as high poverty rates, unsanitary living conditions, and social strife grounded in nativism and economic disparities. This duality in the American perspective reflected both an enthusiastic embrace of new social possibilities and profound worries about the threats to traditional ideals.

The melting pot of American society was stirred by urbanization, seeing an increase in diversity that contributed to the rich fabric of the nation but also led to stereotyping and prejudice. Fiction writers and sociologists of the era sought to capture and critique these complexities, reflecting deep ambivalence about the trajectory of the American society. Urbanization also sparked significant socioeconomic divides, with differences in entertainment and leisure activities reflecting one's status and wealth. Nonetheless, the allure of city life attracted many, and the subsequent suburban expansion and automobile culture further transformed American lifestyles.
