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: "Leaving your footprint in mud, is similar to what process that creates fossils?"

Answer: "Molds and Casts"

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: "Who outraged Libyans of al Qaeda?"

Answer: "The UN Security Council passing a resolution and criticizing their inaction"

Problem: In 1878, Martinez Campos was Governor-General of Cuba, and Maximo Gomez was Commander-in-Chief of the Cuban forces. Both parties were weary of the prolonged hostilities, and neither was able to compel the other to surrender. Spain, however, professed a willingness to yield an important part of the demands of her rebellious subjects. Martinez Campos and Gomez met at Zanjon and, on February 10, 1878, mutually agreed to what has been variously called a peace pact, a treaty, and a capitulation. The agreement was based on provisions for a redress of Cuban grievances through greater civil, political, and administrative privileges for the Cubans, with forgetfulness of the past and amnesty for all then under sentence for political offences. Delay in carrying these provisions into effect gave rise to an attempt to renew the struggle two years later, but the effort was a failure. Matters then quieted down for a number of years. The Cubans waited to see what would be done. The Spanish Governor-General still remained the supreme power and, aside from the abolition of slavery, the application of the Spanish Constitution and Spanish laws to Cuba, and Cuban representation in the Cortes, much of which was rather form than fact, the island gained little by the new conditions. Discontent and protest continued and, at last, broke again into open rebellion in 1895.

Question: "What was the reason for rebellion after the peace pact?"

Answer: "The provision of greater civil, political, and administrative privilleges for Cuban remained unaddressed"
