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.

Sound waves are mechanical waves. They can travel only through matter. They cannot travel through empty space. This was demonstrated in the 1600s by a scientist named Robert Boyle. Boyle placed a ticking clock in a sealed glass jar. The clock could be heard ticking through the air and glass of the jar. Then Boyle pumped the air out of the jar. The clock was still running, but the ticking could not be heard. Thats because the sound couldnt travel without air particles to transfer the sound energy. Is there any other place where sound cannot be heard? Here is a hint: is there any other place that does not have air molecules? Thats right, in space sound cannot be transferred. So can astronauts hear each other? Yes, they can, because they are in enclosed space stations or pressurized suits.In both cases, they are surrounded by air molecules. If they left their space ship and did not use their electronics, they would not be able to hear each other. Next time you watch a science fiction movie, think about this factoid. When spaceships are destroyed by hostile alien beings, there would be no sound heard. Sound waves can travel through many kinds of matter.

Question: "How do astronauts hear each other?"

Response: "though electronics"

Problem: Defeated last month for re-election, Gov. Roy Barnes announced Tuesday that he will spend his first six months out of office as an unpaid attorney for the Atlanta Legal Aid Society, where he will represent poor people. "One day I'll probably do some legal work that I will charge a handsome fee for - at least I hope there are those that are still willing to pay," he told reporters. "But for now, I think it is important to fulfill my duty as a lawyer to help those who need it the most, to speak for those who cannot speak for themselves and to defend those whose life and livelihoods depend on it," he said. Previous governors have gone to prestigious law firms, joined corporate boards or returned to thriving businesses. "I don't think I've ever heard of anybody doing this before," Emory University political science professor Merle Black said. "If he's actually going to represent individuals for that organization, they're going to get great representation. You're going to get some powerful legal muscle there," Mr. Black said. Mr. Barnes said he already has his first case, but he wouldn't say what it is. Atlanta Legal Aid provides civil services to poor people in five metro Atlanta counties. Mr. Barnes said he was hoping to send a message to other lawyers. "This privilege to practice law is just that - it's a privilege. And it comes with a cost and it comes with a bill . We as lawyers have a responsibility to make sure that everyone, regardless of whether they can afford it or not, has quality representation. And if we don't do that, then we're not much of a profession," he said. Steven Gottlieb, the society's executive director, said, "I can't imagine anything that could be better than to have the governor of the state, in his first act as a private citizen, donate six months of his time to represent poor people .

Question:
When land is cleared, habitats are lost. It may be cleared for agriculture. It may also be used for building new homes or businesses. Within the past 100 years, the amount of land used for agriculture has almost doubled. Land used for grazing cattle has more than doubled. Many wetlands have also been lost to agriculture. The U.S. has lost almost all the natural tall-grass prairies. Thee areas of tall thick grass have virtually disappeared. These areas of land had thick fertile soil. Their grasses had very deep root systems. These deep and thick roots reduced the amount of soil erosion. They also were home to many plants and animals. Prairies were wonderful places. They were home to colorful flowers, prairie dogs, and herds of bison. After reading the above, is "kill" the correct answer to the question "How can habitats be lost?"? OPTIONS:
- no
- yes

Answer:
no

What if you could drain all of Earths oceans? What would it look like? You might be really surprised. You see that the surface has two main features. It has continents and ocean basins. Continents are large land areas. These are the areas that are mostly above sea level. Ocean basins extend from the edges of continents. They include the ocean floor and Earths deep ocean trenches. You will also notice the ocean floor is not flat. It too has many Continents are much older than ocean basins. Some rocks on the continents are billions of years old. Ocean basins may only be millions of years old. Because the continents are so old, a lot has happened to them! As we view the land around us, we see landforms. Landforms are physical features on Earths surface. These features change over time, but how? There are actually two types of forces at work.

Question: "What is a landform?"

OPTIONS:
- no
- yes

Answer: "Physical features change over time."

Response:
yes
