Problem: Fossils can be used to match up rock layers. As organisms change over time, they look different. Older fossils will look different than younger fossils. Some organisms only survived for a short time before going extinct. Knowing what organisms looked like at certain times also helps date rock layers. Some fossils are better than others for this use. The fossils that are very distinct at certain times of Earths history are called index fossils. Index fossils are commonly used to match rock layers. You can see how this works in Figure 2.30. If two rock layers have the same index fossils, then they're probably about the same age.

Question: "How can extinction help to date rock layers?"

Answer: "It shows glaciers"

Problem: While this process moved along, diplomacy continued its rounds. Direct pressure on the Taliban had proved unsuccessful. As one NSC staff note put it, "Under the Taliban, Afghanistan is not so much a state sponsor of terrorism as it is a state sponsored by terrorists." In early 2000, the United States began a high-level effort to persuade Pakistan to use its influence over the Taliban. In January 2000, Assistant Secretary of State Karl Inderfurth and the State Department's counterterrorism coordinator, Michael Sheehan, met with General Musharraf in Islamabad, dangling before him the possibility of a presidential visit in March as a reward for Pakistani cooperation. Such a visit was coveted by Musharraf, partly as a sign of his government's legitimacy. He told the two envoys that he would meet with Mullah Omar and press him on Bin Laden. They left, however, reporting to Washington that Pakistan was unlikely in fact to do anything," given what it sees as the benefits of Taliban control of Afghanistan." President Clinton was scheduled to travel to India. The State Department felt that he should not visit India without also visiting Pakistan. The Secret Service and the CIA, however, warned in the strongest terms that visiting Pakistan would risk the President's life. Counterterrorism officials also argued that Pakistan had not done enough to merit a presidential visit. But President Clinton insisted on including Pakistan in the itinerary for his trip to South Asia. His one-day stopover on March 25, 2000, was the first time a U.S. president had been there since 1969. At his meeting with Musharraf and others, President Clinton concentrated on tensions between Pakistan and India and the dangers of nuclear proliferation, but also discussed Bin Laden. President Clinton told us that when he pulled Musharraf aside for a brief, one-on-one meeting, he pleaded with the general for help regarding Bin Laden." I offered him the moon when I went to see him, in terms of better relations with the United States, if he'd help us get Bin Laden and deal with another issue or two." The U.S. effort continued.

Question: "When did President Clinton visit Pakistan and what was discussed between Clinton and Musharraf?"

Answer: "January 2000"

Problem: One look at Fred Rooney, and you just know he's the good guy. A trace of childish innocence in his face gives the lanky Bethlehem lawyer a Jimmy Stewart-like quality of quiet trust. In black jeans and button-down shirt, he's a kind of folk hero in the south Bethlehem melting pot where he's crafted a law practice catering to working-class families - mostly Latino - in the shadow of the hulkish remnants of Bethlehem Steel. A two-hour drive away, at City University of New York Law School in Queens, Rooney spends several days a week helping upstart lawyers develop storefront practices that, like his, provide legal representation to folks who can't afford a $250-an-hour legal counselor. Kristin Booth Glen, the law school's dean, took one look at Rooney and knew he was the right person to head the innovative Community Legal Resources Network. ''Fred's so low-key, he's Midwestern in effect,'' says Glen, a former New York Supreme Court judge. ''He captivates people, he inspires loyalty.'' For bringing legal representation to the poor and a host of other social causes, including finding medical care for seriously ill children in Latin America, the Moravian College Alumni Association has chosen Rooney for its prestigious Haupert Humanitarian Award. The award, given to only a select few alumni, will be presented at 7:30 tonight at a reception on Moravian's Priscilla Payne Hurd campus. Moravian, where he was an undergraduate in the early 1970s, inspired Rooney's deep sense of social justice. The son of a Bethlehem Steel executive in New York, he came to the Bethlehem campus from an affluent upbringing on Long Island. The young Rooney might have set his sights on Washington, D.C., like his uncle, former U.S. Rep. Fred Rooney of Bethlehem. After all, politics run in the Rooney family. His brother, state Rep. T.J. Rooney of Bethlehem, is a power in the state Legislature and the Democratic Party. But on a trip to Colombia when he was a junior at Moravian, the child of privilege saw human suffering, malnutrition and poverty the likes of which he had never imagined. ''I couldn't understand why we live this way and they live that way,'' Rooney recalled. ''It's been the guiding light of my life ever since.'' After graduating in CUNY Law School's first class in 1986, he took a job with Lehigh Valley Legal Services.
