[EX Q]: 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. <sep>What technology made it possible to test the Earth's magnetic properties? How were scientist able to use this machine to study this phenomenon?<sep>Earth has an inner and outer core. The outer core consists of liquid metals, mainly iron and nickel.

[EX Q]: U.S. Secretary of State Colin Powell arrived here on Tuesday night for meetings with fellow foreign ministers aimed at solidifying a second front, in Southeast Asia, in the campaign against global terrorism. But he has had to balance that goal with longstanding concerns about human rights abuses in the region. In meetings on Tuesday in Malaysia and Singapore before touching down in this oil-producing sultanate for two days of talks with members of the Association of South East Asian Nations, Powell said he repeatedly raised the issue. "We still believe strongly in human rights, and that everything we do has to be consistent with universal standards of human rights," he said. But at a news conference in Singapore, Powell hinted that the Bush administration was ready to discuss resuming military cooperation with Indonesia, the world's most populous Muslim nation and a sometimes reluctant partner in the efforts to crack down on militant Islamic groups. The United States cut virtually all military links with Indonesia in 1999 after its forces were implicated in the violence that swept East Timor after that territory voted for independence. On Thursday, Powell and representatives of the nations of the Asian group, including Indonesia, are expected to sign a declaration promising cooperation to prevent terrorism by sharing information, blocking funds, tightening borders and making it hard to use forged travel papers. "We recognized that terrorism is a global threat and that the disturbing acts of terrorism and transnational crimes, which continue to threaten world peace and stability, must be tackled by the international community," the ministers said in a communique on Tuesday. Powell is among the representatives from 13 nations outside Southeast Asia, including China, Japan and Russia, that are taking part in the annual meeting of the group's regional forum. Terrorism dominates the agenda, though the possibility of a meeting here between Powell and his North Korean counterpart, Paek Nam Sun, has generated the most news. It would be the highest-level contact between the United States and North Korea since President Bush took office. Powell heads to Indonesia's capital, Jakarta, late on Thursday before finishing a weeklong trip through the region in the Philippines on Saturday. He said that when he arrives in Jakarta, he will have "some ideas and some initiatives" to present to President Megawati Sukarnoputri. Indonesia is already receiving $400,000 in the current fiscal year for civilian training programs and is to receive a like amount next year; and the United States expects to provide an additional $16 million this year to train police officers in counterterrorism. At the same time, the Pentagon is reviewing how to allocate another $17 million in "counterterrorism fellowships," some of which could go to Indonesia. But a senior State Department official also acknowledged that some in the administration and Congress are pushing for more direct military cooperation, which would require congressional approval. "I think they recognize the danger that we all face and I think they have been cooperating more fully with us as time goes by, and I'm quite sure that Mrs. Megawati is committed to this cause," Powell said in Singapore. He met there with Prime Minister Goh Chok Tong, who endorsed the idea of renewed military ties between the United States and Indonesia as an important step in stabilizing that country. <sep>Who does Secretary Powel say is committed to counterterrorism cause?<sep>President Megawati
[EX A]: Yes

[EX Q]: Bin Laden began delivering diatribes against the United States before he left Saudi Arabia. He continued to do so after he arrived in Sudan. In early 1992, the al Qaeda leadership issued a fatwa calling for jihad against the Western "occupation" of Islamic lands. Specifically singling out U.S. forces for attack, the language resembled that which would appear in Bin Laden's public fatwa in August 1996. In ensuing weeks, Bin Laden delivered an often-repeated lecture on the need to cut off "the head of the snake." By this time, Bin Laden was well-known and a senior figure among Islamist extremists, especially those in Egypt, the Arabian Peninsula, and the Afghanistan-Pakistan border region. Still, he was just one among many diverse terrorist barons. Some of Bin Laden's close comrades were more peers than subordinates. For example, Usama Asmurai, also known as Wali Khan, worked with Bin Laden in the early 1980s and helped him in the Philippines and in Tajikistan. The Egyptian spiritual guide based in New Jersey, the Blind Sheikh, whom Bin Laden admired, was also in the network. Among sympathetic peers in Afghanistan were a few of the warlords still fighting for power and Abu Zubaydah, who helped operate a popular terrorist training camp near the border with Pakistan. There were also rootless but experienced operatives, such as Ramzi Yousef and Khalid Sheikh Mohammed, who-though not necessarily formal members of someone else's organization-were traveling around the world and joining in projects that were supported by or linked to Bin Laden, the Blind Sheikh, or their associates. In now analyzing the terrorist programs carried out by members of this network, it would be misleading to apply the label "al Qaeda operations" too often in these early years. Yet it would also be misleading to ignore the significance of these connections. And in this network, Bin Laden's agenda stood out. While his allied Islamist groups were focused on local battles, such as those in Egypt, Algeria, Bosnia, or Chechnya, Bin Laden concentrated on attacking the "far enemy"-the United States. After U.S. troops deployed to Somalia in late 1992, al Qaeda leaders formulated a fatwa demanding their eviction. In December, bombs exploded at two hotels in Aden where U.S. troops routinely stopped en route to Somalia, killing two, but no Americans. <sep>What was the names and locations of two peers of bin Ladin?<sep>Blind Sheik - New Jersey
