Input: The idea that Earth is a magnet is far from new. It was first proposed in 1600 by a British physician named William Gilbert. Knowing it acts like a magnet is one thing. Knowing why it acts like a magnet is more difficult. In fact, finding out why is a fairly recent discovery. To find out why required new technology. It was the seismograph that made it possible to learn why the Earth acted like a magnet. Seismograph are used to study earthquakes. By studying earthquake waves they were able to learn about Earths interior. They discovered that Earth has an inner and outer core. The outer core consists of liquid metals, mainly iron and nickel. Scientists think that Earths magnetic field is generated here. It is caused by the motion of this liquid metal. The liquid metal moves as Earth spins on its axis.
"How did they learn why the Earth acts like a magnet?" is "By studying earthquake waves they were able to learn about Earths interior"?

Input: (CNN) -- English club Chelsea have completed the signing of Oriol Romeu from Spanish and European champions Barcelona. The 19-year-old is currently playing for Spain at the World Under-20 Championships in Colombia and has signed a four-year deal with last season's Premier League runners-up. The deal is worth $7 million and includes a buy back clause, set at $14 million after the first year and $21 million after the second. Romeu started his career at Barcelona's city rivals Espanyol before joining the Camp Nou academy in 2004. The midfielder, who can also play in central defence, made his debut for Barcelona in last season's Spanish Supercup match with Seville and got his first taste of league action against Deportivo in May 2010. He has played 90 minutes in both of Spain's games at the World Under-20 Championships, when they beat Costa Rica and Ecuador.

Literary career During the war Camus joined the French Resistance cell Combat, which published an underground newspaper of the same name. This group worked against the Nazis, and in it Camus assumed the nom de guerre Beauchard. Camus became the paper's editor in 1943. He first met Sartre at the dress rehearsal of Sartre's play, The Flies, in June 1943. When the Ailies liberated Paris in August 1944, Camus witnessed and reported the last of the fighting. Soon after the event on 6 August 1945, he was one of the few French editors to publicly express opposition and disgust to the United States' dropping the atomic bomb in Hiroshima. He resigned from Combat in 1947 when it became a commercial paper. After the war, Camus began frequenting the Cafe de Flore on the Boulevard Saint-Germain in Paris with Sartre and others. He also toured the United States to lecture about French thought. Although he leaned left, politically, his strong criticisms of Communist doctrine did not win him any friends in the Communist parties and eventually alienated Sartre. In 1949, his tuberculosis returned, whereupon he lived in seclusion for two years. In 1951, he published The Rebel, a philosophical analysis of rebellion and revolution which expressed his rejection of communism. Upsetting many of his colleagues and contemporaries in France, the book brought about the final split with Sartre. The dour reception depressed Camus; he began to translate plays. Camus's first significant contribution to philosophy was his idea of the absurd. He saw it as the result of our desire for clarity and meaning within a world and condition that offers neither, which he expressed in The Myth of Sisyphus and incorporated into many of his other works, such as The Stranger and The Plague. Despite his split from his "study partner", Sartre, Camus was still categorized as an Existentialist. He specifically rejected that label in his essay "Enigma" and elsewhere.

Question: "How long did Camus edit the paper Combat before it became a commercial paper?"

Problem: In chapters 3 and 4 we described how the U.S. government adjusted its existing agencies and capacities to address the emerging threat from Usama Bin Laden and his associates. After the August 1998 bombings of the American embassies in Kenya and Tanzania, President Bill Clinton and his chief aides explored ways of getting Bin Laden expelled from Afghanistan or possibly capturing or even killing him. Although disruption efforts around the world had achieved some successes, the core of Bin Laden's organization remained intact. President Clinton was deeply concerned about Bin Laden. He and his national security advisor, Samuel "Sandy" Berger, ensured they had a special daily pipeline of reports feeding them the latest updates on Bin Laden's reported location. In public, President Clinton spoke repeatedly about the threat of terrorism, referring to terrorist training camps but saying little about Bin Laden and nothing about al Qaeda. He explained to us that this was deliberate-intended to avoid enhancing Bin Laden's stature by giving him unnecessary publicity. His speeches focused especially on the danger of nonstate actors and of chemical and biological weapons. As the millennium approached, the most publicized worries were not about terrorism but about computer breakdowns-the Y2K scare. Some government officials were concerned that terrorists would take advantage of such breakdowns. On November 30, 1999, Jordanian intelligence intercepted a telephone call between Abu Zubaydah, a longtime ally of Bin Laden, and Khadr Abu Hoshar, a Palestinian extremist. Abu Zubaydah said, "The time for training is over." Suspecting that this was a signal for Abu Hoshar to commence a terrorist operation, Jordanian police arrested Abu Hoshar and 15 others and informed Washington. One of the 16, Raed Hijazi, had been born in California to Palestinian parents; after spending his childhood in the Middle East, he had returned to northern California, taken refuge in extremist Islamist beliefs, and then made his way to Abu Zubaydah's Khaldan camp in Afghanistan, where he learned the fundamentals of guerrilla warfare. He and his younger brother had been recruited by Abu Hoshar into a loosely knit plot to attack Jewish and American targets in Jordan. After late 1996, when Abu Hoshar was arrested and jailed, Hijazi moved back to the United States, worked as a cabdriver in Boston, and sent money back to his fellow plotters. After Abu Hoshar's release, Hijazi shuttled between Boston and Jordan gathering money and supplies. With Abu Hoshar, he recruited inTurkey and Syria as well as Jordan; with Abu Zubaydah's assistance, Abu Hoshar sent these recruits to Afghanistan for training.

Question: "Along with Abu Hoshar, who was one of the 15 terrorists arrested by Jordanian authorities?"

Answer: "Bill Clinton"
