QUES: Magnetism is the ability of a material to be attracted by a magnet. It also include the ability for some material to act like a magnet. No doubt youve handled refrigerator magnets. You can see some in Figure 1.28. You probably know they stick to a metal refrigerator. This is what holds your homework up. Maybe your little sisters drawings are hung on the fridge in this manner. Do magnets stick to all materials? Of course not. You have probably checked and they do not stick to other surfaces. They do not stick to wooden doors or glass windows. Wood and glass are not attracted to a magnet. Obviously, only certain materials are attracted to magnets.

QUES: The explosion, while killing one of the Cossacks and seriously wounding the driver and people on the sidewalk, had only damaged the bulletproof carriage, a gift from Napoleon III of France. The emperor emerged shaken but unhurt. Rysakov was captured almost immediately. Police Chief Dvorzhitsky heard Rysakov shout out to someone else in the gathering crowd. The surrounding guards and the Cossacks urged the emperor to leave the area at once rather than being shown the site of the explosion. Nevertheless, a second young member of the Narodnaya Volya, Ignacy Hryniewiecki, standing by the canal fence, raised both arms and threw something at the emperor's feet. He was alleged to have shouted, "It is too early to thank God". Dvorzhitsky was later to write:

QUES: Alexander II's death caused a great setback for the reform movement. One of his last ideas was to draft plans for an elected parliament, or Duma, which were completed the day before he died but not yet released to the Russian people. In a matter of 48 hours, Alexander II planned to release his plan for the duma to the Russian people. Had he lived, Russia might have followed a path to constitutional monarchy instead of the long road of oppression that defined his successor's reign. The first action Alexander III took after his father's death was to tear up those plans. A Duma would not come into fruition until 1905, when Alexander II's grandson, Nicholas II, commissioned the Duma following extreme pressure on the monarchy as a result of the Russian Revolution of 1905. The assassination triggered major suppression of civil liberties in Russia, and police brutality burst back in full force after experiencing some restraint under the reign of Alexander II, whose death was witnessed first-hand by his son, Alexander III, and his grandson, Nicholas II, both future emperors who vowed not to have the same fate befall them. Both of them used the Okhrana to arrest protestors and uproot suspected rebel groups, creating further suppression of personal freedom for the Russian people. A series of anti-Jewish pogroms and antisemitic legislation, the May Laws, were yet another result. Finally, the tsar's assassination also inspired anarchists to advocate "'propaganda by deed'--the use of a spectacular act of violence to incite revolution." With construction starting in 1883, the Church of the Savior on Blood was built on the site of Alexander's assassination and dedicated in his memory.

QUES: Tuesday, September 11, 2001, dawned temperate and nearly cloudless in the eastern United States. Millions of men and women readied themselves for work. Some made their way to the Twin Towers, the signature structures of the World Trade Center complex in New York City. Others went to Arlington, Virginia, to the Pentagon. Across the Potomac River, the United States Congress was back in session. At the other end of Pennsylvania Avenue, people began to line up for a White House tour. In Sarasota, Florida, President George W. Bush went for an early morning run. For those heading to an airport, weather conditions could not have been better for a safe and pleasant journey. Among the travelers were Mohamed Atta and Abdul Aziz al Omari, who arrived at the airport in Portland, Maine. Boston: American 11 and United 175. Atta and Omari boarded a 6:00 A.M. flight from Portland to Boston's Logan International Airport. When he checked in for his flight to Boston, Atta was selected by a computerized prescreening system known as CAPPS (Computer Assisted Passenger Prescreening System), created to identify passengers who should be subject to special security measures. Under security rules in place at the time, the only consequence of Atta's selection by CAPPS was that his checked bags were held off the plane until it was confirmed that he had boarded the aircraft. This did not hinder Atta's plans. Atta and Omari arrived in Boston at 6:45. Seven minutes later, Atta apparently took a call from Marwan al Shehhi, a longtime colleague who was at another terminal at Logan Airport. They spoke for three minutes. It would be their final conversation.

Where did Atta and Oari travel from, and where did they travel to?
