Input: Light rays strike a reflecting surface. They are then reflected back. You can predict the angle of the reflected light. Imagine a ball bouncing off a surface. Light can do the same thing. That is, assuming the surface is shiny. So how do you know where light will go after it strikes a shiny surface? It depends on how the light initially strikes the shiny object. Light does not always go straight toward a surface. Therefore, not all light bounces straight back. Sometimes, light can hit a surface at an angle. The angle at which it strikes the surface tells us how it will bounce off. While light is different to a ball, they react in a similar manner. Many sports rely on knowledge of reflection. Pool players know a lot about reflection. They take great care when they strike the pool ball. They need it to go to a certain place. They know the angle it will hit the side of the pool table.

Does the response "People who engage in many sports." correctly answer the question "What type of people know alot about reflection?"?

Input: Among the early blows struck for independence was a rebellion in the town of Olhao. On 16 June 1808, the townsfolkarmed with little more than ancient swords, spears, and stonesattacked and captured the local French garrison. It's said that a party of local men then set sail from Olhao all the way to Brazil, without maps or navigational aids, to tell the king of the insurrection. The real battle, however, was waged under the leadership of the Duke of Wellington, whose coalition forces expelled the French after two years of bitter fighting. The war left Portugal further weakened, and in 1822 its major empire outpost, Brazil, declared independence. At the same time, a dispute over the crown continually raged between Pedro IV, the absentee monarch who preferred to reign as Emperor of Brazil rather than return to Portugal, and his brother Miguel. The power struggle, with strong overtones of absolutism versus liberalism, excited the interest and intervention of other powers. With British help, Pedro defeated Miguel off Cape St. Vincent in 1833, and his expeditionary force marched to Lisbon. Pedro took the throne, though armed struggle continued for months and the lingering bitterness long after that. By 1892 Portugal, racked by wars and the continuing expense of maintaining its African colonies (including those of Mozambique and Angola), declared itself bankrupt. The seeds of discontent with absolutist rule were sown. Kingdom's End Bloodshed would haunt the remaining years of the Portuguese monarchy. On 1 February 1908, the royal family was riding in an open carriage along the Lisbon river front plaza, Terreiro do Paco, when an assassin opened fire and killed King Carlos and the heir to the throne, Prince Luis Filipe. The prince's younger brother, Prince Manuel, was also hit, but he survived and was thus propelled to the throne at the tender age of 19. Amid republican agitation, a surprise uprising led by elements within the armed forces deposed Manuel in 1910. Having ruled for less than three years, Manuel died in exile in 1932 in England. The sudden end of more than seven centuries of monarchy brought confusion and crisis to the country. Presidents and prime ministers were ushered into and out of office an unbelievable 45 times between 1910 and 1926, until a military revolution suspended Portugal's problematic democracy.

Does the response "Yes" correctly answer the question "Did Pedro IV take the throne peacefully?"?

Input: U.S. Secretary of State Colin Powell arrived here on Tuesday night for meetings with fellow foreign ministers aimed at solidifying a second front, in Southeast Asia, in the campaign against global terrorism. But he has had to balance that goal with longstanding concerns about human rights abuses in the region. In meetings on Tuesday in Malaysia and Singapore before touching down in this oil-producing sultanate for two days of talks with members of the Association of South East Asian Nations, Powell said he repeatedly raised the issue. "We still believe strongly in human rights, and that everything we do has to be consistent with universal standards of human rights," he said. But at a news conference in Singapore, Powell hinted that the Bush administration was ready to discuss resuming military cooperation with Indonesia, the world's most populous Muslim nation and a sometimes reluctant partner in the efforts to crack down on militant Islamic groups. The United States cut virtually all military links with Indonesia in 1999 after its forces were implicated in the violence that swept East Timor after that territory voted for independence. On Thursday, Powell and representatives of the nations of the Asian group, including Indonesia, are expected to sign a declaration promising cooperation to prevent terrorism by sharing information, blocking funds, tightening borders and making it hard to use forged travel papers. "We recognized that terrorism is a global threat and that the disturbing acts of terrorism and transnational crimes, which continue to threaten world peace and stability, must be tackled by the international community," the ministers said in a communique on Tuesday. Powell is among the representatives from 13 nations outside Southeast Asia, including China, Japan and Russia, that are taking part in the annual meeting of the group's regional forum. Terrorism dominates the agenda, though the possibility of a meeting here between Powell and his North Korean counterpart, Paek Nam Sun, has generated the most news. It would be the highest-level contact between the United States and North Korea since President Bush took office. Powell heads to Indonesia's capital, Jakarta, late on Thursday before finishing a weeklong trip through the region in the Philippines on Saturday. He said that when he arrives in Jakarta, he will have "some ideas and some initiatives" to present to President Megawati Sukarnoputri. Indonesia is already receiving $400,000 in the current fiscal year for civilian training programs and is to receive a like amount next year; and the United States expects to provide an additional $16 million this year to train police officers in counterterrorism. At the same time, the Pentagon is reviewing how to allocate another $17 million in "counterterrorism fellowships," some of which could go to Indonesia. But a senior State Department official also acknowledged that some in the administration and Congress are pushing for more direct military cooperation, which would require congressional approval. "I think they recognize the danger that we all face and I think they have been cooperating more fully with us as time goes by, and I'm quite sure that Mrs. Megawati is committed to this cause," Powell said in Singapore. He met there with Prime Minister Goh Chok Tong, who endorsed the idea of renewed military ties between the United States and Indonesia as an important step in stabilizing that country.

Does the response "Powell's North Korean Counterpart" correctly answer the question "Who is Paek Nam Sun?"?
