3. What does 9/11 refer to? Give a short overview of the disaster.
Answer:

9/11 conspiracy theories allege that the September 11 attacks in 2001 were either intentionally allowed to happen or were a false flag operation orchestrated by an organization with elements inside the United States government. The most prominent theory is that the collapse of the World Trade Center and 7 World Trade Center were the result of a controlled demolition rather than structural weakening due to fire. Another prominent belief is that the Pentagon was hit by a missile launched by elements from inside the U.S. government or that a commercial airliner was allowed to do so via an effective standdown of the American military. The commonly claimed motives are to justify the invasion of Afghanistan and Iraq, leading to subsequent US control of their vast oil resources; to facilitate increased military spending; and to restrict domestic civil liberties.
4. What happened on the 14th April 1912? What were the consequences?
Answer:

USS America was a troop transport for the United States Navy during World War I. She was launched in 1905 as SS Amerika by Harland and Wolff in Belfast for the Hamburg America Line of Germany. As a passenger liner, she sailed primarily between Hamburg and New York. On 14 April 1912, Amerika transmitted a wireless message about icebergs near the same area where RMS Titanic struck one and sank less than 24 hours later. At the outset of World War I, Amerika was interned at Boston rather than risking seizure by the British Royal Navy.
The sinking resulted in the deaths of 1,517 of the 2,223 people on board, making it one of the deadliest peacetime maritime disasters in history.
5. Why is the ship Mayflower so important in American history? What happened?
Answer:

The Mayflower was used primarily as a cargo ship, involved in active trade of goods (often wine) between England and other European countries. At least between 1609 and 1622, it was mastered by Christopher Jones, who would command the ship on the famous transatlantic voyage, and based in Rotherhithe, London, England.
his ship also made the crossing from England to America in 1630, 1633, 1634, and 1639. It attempted the trip again in 1641, departing London in October of that year under master John Cole, with 140 passengers bound for Virginia. It never arrived. On October 18, 1642 a deposition was made in England regarding the loss.
6. What was the significant event that took place on July 16, 1969? Illustrate.
Answer:

The Apollo 11 mission landed the first humans on the Moon. Launched on July 16, 1969, the third lunar mission of NASA's Apollo Program was crewed by Commander Neil Alden Armstrong, Command Module Pilot Michael Collins, and Lunar Module Pilot Edwin Eugene 'Buzz' Aldrin, Jr. On July 20, Armstrong and Aldrin became the first humans to land on the Moon, while Collins orbited in the Command Module.
The mission fulfilled President John F. Kennedy's goal of reaching the moon by the end of the 1960s, which he had expressed during a speech given before a joint session of Congress on May 25, 1961: "I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth."
7. What relevant event took place on January 20th 2009 in the United States? Illustrate.
Answer:

Barack Obama was inaugurated as president of the United States on January 20, 2009
8. What was Arpanet and why is this term and the man called Tim Berners-Lee very important in the world's history?
Answer:

The first network of computers involved just 4 machines collectively called Arpanet. This took place in 1969 and was funded by America’s Defence Department’s Research Projects Agency.
In the late 1970’s, Arpanet sought to change this. They wanted to devise an inter-networking system whereby different networks could ‘talk’ to one another. Arpanet devised TCP/IP. This was a set of rules for communication between networks. The Internet became a network of networks. Only the military stayed outside of this for security reasons. Such a transfer of vast amounts of information had been unthinkable just a decade earlier but TCP/IP changed all this.
n 1988, there were 50,000 computers attached to the Internet. By 1991, there were 1 million. However, it was difficult to access the information contained on the Internet as the system had little organisation. This problem was solved by Tim Berners-Lee, a British scientist studying at a research facility in Switzerland. He invented a method of organising information which he called the world-wide-web (www). His system linked documents from different sources and guided users to related information. The www was first used by the public in 1991 and it allowed the transfer of text, sound, images and video clips. Above all else, it was simple to use.
9. Why is the date - September 1, 1939 – considered to be very significant date in the history of the world?
Answer:

On September 1, 1939, Hitler told the Nazi Reichstag that Poland had tried to invade Germany, and the Wehrmacht was returning fire since 5:45 AM. Actually, in a carefully planned and highly mobile attack codenamed Fall Weiss (Case White) planned by Generalfeldmarschall Walther von Brauchitsch, German land, sea, and air forces were moving rapidly into Poland.
Poland’s army in 1939 was totally unprepared for the new warfare it found itself in. Poland, like many armies, had large cavalry forces. What modern aircraft the Polish Air Force had were caught on the ground.
10. What started on the morning of December 7, 1941? Give a short overview.
Answer:
The attack on Pearl Harbor was an unannounced military strike conducted by the Japanese navy against the United States naval base at Pearl Harbor, Hawaii on the morning of December 7, 1941. It resulted in the United States' entry into World War II. The attack was intended as a preventive action in order to keep the U.S. Pacific Fleet from influencing the war that the Empire of Japan was planning in Southeast Asia, against Britain and the Netherlands, as well as the U.S. in the Philippines. The attack consisted of two aerial attack waves totaling 353 aircraft, launched from six Japanese aircraft carriers.
