The Articles of Confederation was the first written constitution of the United States. Stemming from wartime urgency, its progress was slowed by fears of central authority and extensive land claims by states before was it was ratified on March 1, 1781. Under these articles, the states remained sovereign and independent, with Congress serving as the last resort on appeal of disputes. Congress was also given the authority to make treaties and alliances, maintain armed forces and coin money. However, the central government lacked the ability to levy taxes and regulate commerce, issues that led to the Constitutional Convention in 1787 for the creation of new federal laws.
The correct answer is B.
The Korean War was fought between 1950 and 1953. It was considered a proxy war in the major conflict known as Cold War, that confronted the Eastern bloc of communist countries leaded by the URSS and the Western bloc of capitalist countries headed by the US.
When the Korean War started, the country had splitted in two halves and North Korea attempted to invade South Korea. The communist North was supported by the URSS and China while the South was supported by the US.
The presidency of George Washington began on April 30, 1789, when Washington was inaugurated as the first President of the United States, and ended on March 4, 1797. Washington took office after the 1788–89 presidential election, the nation's first quadrennial presidential election, in which he was elected unanimously. Washington was re-elected unanimously in the 1792 presidential election, and chose to retire after two terms. He was succeeded by his vice president, John Adams of the Federalist Party.
Washington had established his preeminence among the new nation's Founding Fathers through his service as Commander-in-Chief of the Continental Army during the American Revolutionary War and as President of the 1787 Constitutional Convention. Once the Constitution was approved, it was widely expected that Washington would become the first President of the United States, despite his own desire to retire from public life. In his first inaugural address, Washington expressed both his reluctance to accept the presidency and his inexperience with the duties of civil administration, but he proved an able leader.
