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.

Earth processes have not changed over time. The way things happen now is the same way things happened in the past. Mountains grow and mountains slowly wear away. The same process is at work the same as it was billions of years ago. As the environment changes, living creatures adapt. They change over time. Some organisms may not be able to adapt. They become extinct. Becoming extinct means they die out completely. Some geologists study the history of the Earth. They want to learn about Earths past. They use clues from rocks and fossils. They use these clues to make sense of events. The goal is to place things in the order they happened. They also want to know how long it took for those events to happen. 

Question: "What do geologists study to give them clues about the Earth's past?"

Response: "Whats happening in the future"
OPTIONS:
- no

Problem: (CNN) -- Shain Gandee, one of the stars of the MTV reality show "Buckwild," has been found dead along with two other people in Kanawha County, West Virginia, authorities said Monday. "This is a very sad and tragic event," Kanawha County Commissioner Kent Carper said. "We live in a very small community. Our thoughts and prayers are with the Gandee family." Gandee, 21, was found dead in a vehicle along with his uncle, David Dwight Gandee, 48, and Donald Robert Myers, 27, authorities said. 'Buckwild' producer talks about the show "Earlier this day after releasing information Shain Gandee was missing, the Kanawha County Sheriff's Office received word of a disabled vehicle in a wooded area near Thaxton Hollow, Sissonville, Kanawha County WV," said a statement from the Sheriff's Office. "Deputies and members of the Sissonville Volunteer Fire Department used all terrain vehicles to access that vehicle, a 1984 Ford Bronco belonging to the Gandee family. The vehicle was in a muddy area along a worn path. Inside were the bodies of three people." In a subsequent release, the Sheriff's Office said the vehicle was partially submerged in mud. It was uneven but upright; its muffler was below the surface. Mud covered the lower part of the Bronco's passenger side door, but the driver's side, where the younger Gandee sat, was free, the Sheriff's Office said. Gandee was happy with life before death He was one of the nine cast members of "Buckwild." The show follows a group of young adults trying to have fun in Sissonville, West Virginia, pulling stunts such as turning a dump truck into a swimming pool or just riding around the woods on their all-terrain vehicles. Gandee was billed as a former high school prom king who had done "every job from coal mining to being a garbage man." 

Question: "Was Shain Gandee alone when he was found dead?"

Answer: "No, he was found with his uncle and two more people"

Question:
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.  After reading the above, is "Robert Boyle" the correct answer to the question "Who demonstrated that sound could not travel through empty space, but only matter?"? OPTIONS:
- no
- yes

Answer:
yes
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. 

Question: "What types of animals did prairies contain?"

OPTIONS:
- no
- yes

Answer: "Iguanas, bull"

Response:
no
