Problem: Fossils may form in other ways. Fossils can be preserved almost completely. In this process, the organism doesnt change much. As seen below, tree sap may cover an organism. With time, the sap hardens. It turns to into amber. The original organism is preserved. This is very exciting for scientists. They are able to study the DNA of the organism that no longer lives on Earth. Some animals have been found frozen in ice. Others have been found in tar pits after falling in. Molds and casts are another way organisms can be fossilized. Have you ever walked in soft mud and left footprints? Once in a while, these traces of organisms can be preserved. In this case, nothing is left of the organism. A mold is an imprint of an organism that is preserved in rock. The organisms remains break down completely. There is nothing left of the original plant and animal.

Question: "What are three materials an organism can be preserved in?"

Answer: "Ice, amber, and tar"

Problem: Not until 1998 did al Qaeda undertake a major terrorist operation of its own, in large part because Bin Laden lost his base in Sudan. Ever since the Islamist regime came to power in Khartoum, the United States and other Western governments had pressed it to stop providing a haven for terrorist organizations. Other governments in the region, such as those of Egypt, Syria, Jordan, and even Libya, which were targets of some of these groups, added their own pressure. At the same time, the Sudanese regime began to change. Though Turabi had been its inspirational leader, General Omar al Bashir, president since 1989, had never been entirely under his thumb. Thus as outside pressures mounted, Bashir's supporters began to displace those of Turabi. The attempted assassination in Ethiopia of Egyptian President Hosni Mubarak in June 1995 appears to have been a tipping point. The would-be killers, who came from the Egyptian Islamic Group, had been sheltered in Sudan and helped by Bin Laden. When the Sudanese refused to hand over three individuals identified as involved in the assassination plot, the UN Security Council passed a resolution criticizing their inaction and eventually sanctioned Khartoum in April 1996. A clear signal to Bin Laden that his days in Sudan were numbered came when the government advised him that it intended to yield to Libya's demands to stop giving sanctuary to its enemies. Bin Laden had to tell the Libyans who had been part of his Islamic army that he could no longer protect them and that they had to leave the country. Outraged, several Libyan members of al Qaeda and the Islamic Army Shura renounced all connections with him. Bin Laden also began to have serious money problems. International pressure on Sudan, together with strains in the world economy, hurt Sudan's currency. Some of Bin Laden's companies ran short of funds. As Sudanese authorities became less obliging, normal costs of doing business increased. Saudi pressures on the Bin Laden family also probably took some toll. In any case, Bin Laden found it necessary both to cut back his spending and to control his outlays more closely.

Question: "Why did Bin Laden tell his Islamic Army he could no longer protect them and that they needed to leave the country?"

Answer: "Because of his financial problems"

Problem: The Bush administration in its first months faced many problems other than terrorism. They included the collapse of the Middle East peace process and, in April, a crisis over a U.S." spy plane" brought down in Chinese territory. The new administration also focused heavily on Russia, a new nuclear strategy that allowed missile defenses, Europe, Mexico, and the Persian Gulf. In the spring, reporting on terrorism surged dramatically. In chapter 8, we will explore this reporting and the ways agencies responded. These increasingly alarming reports, briefed to the President and top officials, became part of the context in which the new administration weighed its options for policy on al Qaeda. Except for a few reports that the CSG considered and apparently judged to be unreliable, none of these pointed specifically to possible al Qaeda action inside the United States-although the CSG continued to be concerned about the domestic threat. The mosaic of threat intelligence came from the Counterterrorist Center, which collected only abroad. Its reports were not supplemented by reports from the FBI. Clarke had expressed concern about an al Qaeda presence in the United States, and he worried about an attack on the White House by "Hizbollah, Hamas, al Qida and other terrorist organizations." In May, President Bush announced that Vice President Cheney would himself lead an effort looking at preparations for managing a possible attack by weapons of mass destruction and at more general problems of national preparedness. The next few months were mainly spent organizing the effort and bringing an admiral from the Sixth Fleet back to Washington to manage it. The Vice President's task force was just getting under way when the 9/11 attack occurred.

Question: "What other countries did the Bush administration have to deal with other than al Qaeda?"

Answer: "Australia"
