Problem: 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?"

Answer: "Boyle carries them with his empty jar."

Question:
Reuters Holdings PLC said Michael Reupke resigned as general manager to pursue unspecified interests, a move the news organization termed an "amicable separation." Mr. Reupke, 52 years old and a 27-year Reuters veteran, had been the information-services company's general manager for only six months. His appointment to that post, which has senior administrative, staff and policy responsibilities, followed a several-year tenure as Reuters's editor in chief. No successor was named, and Mr. Reupke's duties will be split among three other senior Reuters executives, the company said. In a telephone interview, Mr. Reupke said his departure was for "personal reasons," which he declined to specify. "There is no business reason for my departure," nor any disagreement over policy, he added. He also rejected reports that his departure stemmed from disappointment the general manager's post hadn't also led to a board directorship at the London-based news organization. Mr. Reupke was one of three executives on Reuters's eight-person executive committee who didn't also serve on the company's board of directors. "If I were choosing the people of tomorrow, I would have chosen the people who are now on the board," he said. A Reuters spokesman said the departure reflects "no change in strategy or profits." Mark Shepperd, an analyst at UBS Philips & Drew in London, said, "I suspect (the departure) will be fairly irrelevant for the company. I would be very surprised if his departure signals any change in strategy or change in profit expectations." On London's Stock Exchange, Reuters shares rose five pence to 913 pence ($14.43). In the U.S. over-the-counter market, American depositary shares for Reuters, each representing three shares in the London market, closed unchanged at $43.875. The senior of the three executives who will assume Mr. Reupke's duties is Nigel Judah, 58, finance director and a Reuters board director. Peter Holland, 45, deputy general manager, becomes director of corporate affairs. And Patrick Mannix, 46, international technical manager, becomes director of group quality programs. After reading the above, is "Information-services company's general manager" the correct answer to the question "What position did Reupke hold one year ago?"? OPTIONS:
- no
- yes

Answer:
yes

Input: Peace and Prosperity: After years of government propaganda predicting the worst atrocities, most Japanese civilians were surprised at the warmth and friendliness of the occupying forces. The postwar period began, however, with millions of displaced people homeless and starving. To counter a perceived communist threat from the Soviet Union, the US quickly set to work reconstructing the economy by transforming Japan's institutions and devising a new pacifist constitution. Article 9 renounced Japan's right to maintain armed forces, although the ambiguous wording was later taken to permit the creati on of a "self-defense" force. The zaibatsu conglomerates that had proved so instrumental in boosting Japan's militarism were disbanded, later to re-emerge as the keiretsu trading conglomerates that dominated the economy once again. The entire economy received a massive jump-start with the outbreak of the Korean War, with Japan ironically becoming the chief local supplier for an army it had battled so furiously just a few years earlier. The occupation lasted until 1952, having already planted the seeds for Japan's future stunning economic success. Economic output was back to prewar levels, and British auto companies provided the support needed to get Japan's auto industry back on its feet. Japanese companies then enthusiastically imported any Western technologies they could get their hands on. This included transistor technologyinvented in the US but then considered to have only limited applicationsfor the surreal sum of $25,000. It was Japan that produced the world's first transistor radio. The electronic technology spurt that followed is now legendary. Parliamentary democracy finally came into its own, albeit with distinctly Japanese characteristics reflecting the dislike of debate and confrontation and the group-oriented preference for maintaining the appearance of harmony at all times. The government, through the powerful Finance Ministry and Ministry of International Trade and Industry, generously supported favored private corporations: first shipping, then cars, then electronics firms basked in the warmth of the government's loving attentions. Japan overtook Britain economically in 1964. By the end of the decade, Japan's was the third largest economy in the worldless then two decades after the war had left the country in ruins. Prosperity was not without its own problems: pollution caused by "dirty" industries, a high incidence of stomach ulcers (even suicides) among schoolchildren pressured by over-ambitious parents, and the awkward questions of what to do about nuclear energy. The famous coziness among politicians, bureaucrats, and private companies, together with the strong cultural emphasis on relationship-building and a lack of transparency and accountability, eventually led to corrupt practices of endemic proportions.
"Japan was the third largest economy by the end of which decade?" is "Finance Ministry"?

Input: Nine families displaced by a fire at Alamo Hills Apartments in March filed lawsuits Wednesday against the apartment complex. They allege that the complex could have done more to protect belongings they were forced to abandon in the aftermath of the blaze. Bernard Dempsey Jr., an attorney with Western Michigan Legal Services, the group that represents the tenants, said Alamo Hills gave the displaced families very limited opportunity to remove belongings. "They were given three days to get their stuff out, and if they couldn't get moved out in three days, their stuff was discarded," Dempsey said. "Alamo Hills just threw it out." Others, he said, lost possessions to looters after the March 23 blaze, which left 78 people temporarily homeless. According to the lawsuit, the tenants were prohibited from entering their apartments to retrieve possessions and were promised that the complex would provide security. A spokesperson for PM One, the company that manages Alamo Hills, could not be reached for comment. Nine separate suits were filed in 8th District Court, which handles civil claims of less than $25,000. "We're asking for the reimbursement of the value of their property and a small amount for stress -- $3,000 on top of their out-of-pocket expenses for their lost stuff," Dempsey said. "They're not looking to get rich off this. A lot of this is simply because they were treated so badly." Dempsey said most of the tenants who filed suits still live at the apartment complex, although many are trying to find homes elsewhere. "The new apartments (they were provided) were not in very good shape. That's actually one of the claims," he said.
"What did nine families claim Alamo Hills Apartments failed to protect?" is "Their apartments"?
