Input: 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.

Does the response "Albert Einstein" correctly answer the question "Who demonstrated that sound could not travel through empty space, but only matter?"?

Input: Still untaken are several steps that required goodwill from local bar associations and others who had opposed the combination. "[I am] not a fan of Neal's," admitted John Peck, a former board member of the San Gabriel-Pomona Valley program and a Pasadena Bar Association board member. Peck says bad feelings still linger among Ailies of the old program who feel left out. "They really screwed us. We had a good program," Peck said. An observer familiar with the reconfiguration debate who requested anonymity wondered why Dudovitz had not spent more time mending fences. "He ought to be bending over backwards for reconciliation, but if you want to do impact work and people in the San Gabriel Valley want direct services, you have to accommodate that or change your approach," the observer said. "Neal would never consider doing that." More than a year after he officially incorporated the San Gabriel-Pomona Valley, Dudovitz had not placed a local resident on the board of Neighborhood Legal Services or made the rounds of the private legal community to recruit the volunteer lawyers. "Our emphasis has been on having our potential clients know about us and deliver services to them," Dudovitz said. "We have done that spectacularly." He did not hire any of the old program's nine lawyers and has yet to permanently place any of his 18 new hires in the San Gabriel-Pomona Valley. The lack of a legal aid presence in Pomona prompted the bar association and court officials to start their own once-monthly family law clinic. After learning of the effort, Dudovitz sent personnel to staff the clinic for three hours per week and is helping to write a grant application to fund a self-help kiosk for Pomona patterned on the center he pioneered in Van Nuys. The help, although late, has earned Dudovitz some appreciation. "There has been a transition and [the clinic] has helped to fill some void," said Deni Butler, administrator for the Eastern District Superior Court. "But we are working together quite nicely contrary to what the other side issue is." Scott Wheeler, president of the Eastern Bar Association of Los Angeles and an ally of the old program, said he mobilized his 200 members to staff the clinic after watching the ranks of unserved poor grow over the past year.

Does the response "Neal" correctly answer the question "An observer stated: "He ought to be bending over backwards for reconciliation." Who is the observer referring to?"?

Input: The digestive system is the body system that digests food. It digest food in two ways, mechanically and chemically. Both help in the process of turning food into nutrients. The digestive system also eliminates solid food waste. The major organs of the digestive system include the mouth, esophagus, stomach, and small and large in- testines. These organs all work together to help you gain energy from the food you eat. Digestion starts in the mouth. When food is swallowed, it travels through the esophagus to the stomach. In the stomach, digestion continues and a small amount of absorption of nutrients takes place. Most chemical digestion and nearly all absorption of nutrients take place in the small intestine. This organ consists of three parts: duodenum, jejunum, and ileum. The large intestine is the last stop in the digestive system. This is where water is absorbed. The food not digested is released as waste.

Does the response "In the stomach and small intestine" correctly answer the question "Where does the absorption of nutrients take place?"?

Input: 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.

Does the response "Bin Laden" correctly answer the question "Which group plotted the assassination of Hosni Mubarak?"?
