Problem: It is not enough to describe some objects by their location. We may also need to know its direction. For example, a wind blows a storm over your school. Where is that storm coming from? Where is it going? How can we describe a direction? The most common way is by using a compass. A compass is a device with a floating needle (Figure 2.1). The needle is a small magnet. The needle aligns itself with the Earth's magnetic field. The compass needle always points to magnetic north. If you have a compass and you find north. You can then know any other direction. See the directions, such as east, south, west, etc., on a compass rose. The Earth has two poles. It has a magnetic north pole. It also has a geographic north pole. These two poles are close to each other but not the exact same place. 

Question: "What device has a needle that is a small magnet?"

Answer: "map"
Answer: no

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.
