Based on historical context, the federalists argued against state sovereignty. Federalists concluded that for the country to join together, the state should not be sovereign but be under a strong central government.

In contrast, Anti-federalists want the state government to be sovereign from the central government to protect the people's interests.

On President power, Federalists supported the President's power and the executive to carry out federal laws and foreign relation policy.

In contrast, Anti-federalists believed that President's power would make the presidency become elected monarch with a tendency to become a tyrant.

On political corruption, federalists believed that separation of powers among the branches of government would curb political corruption.

In contrast, Anti-federalists argued that the three branches of government and the new constitution would only promote political corruption among the elected people.

On taxation, Federalists supported the idea that the central government should have the power to impose taxes for national defense and repayment of national debts.

In contrast, anti-federalists debated that such power would make the central government impose unfair and repressive taxes.

Hence, in this case, it is concluded that Federalists and Anti-Federalists held contrasting views on many key issues in the early period of the United States formation.

Explanation:

The space was a well-constructed thrust stage however, the stage was not raised off the ground and the seats appeared to be mobile which lead to the belief that this is an Environmental Theater. As for the layout of the stage, there was a couch and a table in center stage for the first two acts, a door to the unseen outside front of the house upstage right, there were two large double doors upstage center leading to the backyard garden, and a raised floor upstage left containing a piano, a bookcase and a door leading to the home library. Stage left there was a half spiral staircase that lead up to the second floor which had a painting and lights that extended across to stage right. The second floor also contained the bedrooms for the house but the doors were not in sight. The detail was greater than expected: the hardwood floor throughout the first floor seemed to be genuine, the actual bookcase filled with real books not stage books, and the extremely large double doors with translucent glass and floral designs lead to the Garden, which featured an array of plants behind the doors. The entire space was well lit for the duration of the play; the stage took place inside the Bliss’ home so the bright lighting added a confortable feel to the inside of the house. The theatre was nearly sold out; it was hard to spot an empty seat, including the balcony and lower level seating. The crowd contained nearly an even amount of student audience members and senior citizens; there was few in the audience that appeared middle aged.

What was the “whisper campaign” and how did Washington respond to it?

Answers

Answer:

whispering campaign or whisper campaign is a method of persuasion in which damaging rumors or innuendo are spread about the target, while the source of the rumors seeks to avoid being detected while spreading them. For example, a political campaign might distribute anonymous flyers attacking the other candidate. It is generally considered unethical in open societies, particularly in matters of public policy. The speed and anonymity of communication made possible by modern technologies like the Internet has increased public awareness of whisper campaigns and their ability to succeed. This phenomenon has also led to the failure of whisper campaigns, as those seeking to prevent them are able to publicize their existence much more readily than in the past. Whisper campaigns are defended in some circles as an efficient mechanism for underdogs who lack other resources to disclose wrongdoings of the powerful without repercussions.

Essay on why you would quit valley forge?(help)!

Answers

Answer:

The harsh environment of Valley Forge provided many motivations for soldiers to quit. This included sick soldiers suffering from the cold, frostbite, and disease. The soldiers were housed in small huts with poor ventilation that lead to the spread of illness and disease. Around 2,000 soldiers died from disease. The Continental Army struggles with supply problems while also trying to retrain and reorganize their army. Rather than snow and frigid temperatures, it was actually the rainy, temperate weather at Valley Forge that turned the surrounding roads to mud, further hindering an already tenuous supply network. In addition, local farmers were more likely to send their foodstuffs to the British army who had currency that could be used immediately for exchange. The Continental army could only offer the farmers devalued paper currency our vouchers the farmers could use in the future to make back their expenditures. All in, the problems the Continental Army faced at Valley Forge were holistic and affected every aspects of the army and every soldier's life.

How did Rome’s government help unify the empire

Answers

Explanation:

Rome was able to gain its empire in large part by extending some form of citizenship to many of the people it conquered. Military expansion drove economic development, bringing enslaved people and loot back to Rome, which in turn transformed the city of Rome and Roman culture.

The emperor Diocletian decided to divide it into western and eastern halves in A.D. 285 to make managing the empire easier. Competition between the leaders of the halves emerged and resulted in civil war, which ultimately led the general Constantine to unify the empire under his own rule.

President Franklin D. Roosevelt felt that creating jobs was a better fix to the hardships of the Depression than government handouts of money.
