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 "Yes, they do." correctly answer the question "Do pool players use the principles of reflection to get a ball to go to a certain place?"?

Input: (CNN) -- Japan's prime minister conceded defeat in parliamentary elections Sunday, signaling the return to power of the Liberal Democratic Party and ending the brief rule of the disappointing upstart Democratic Party of Japan. Prime Minister Yoshihiko Noda pledged to step down as party president after exit polls showed a smashing loss in lower house voting. The party, once seen as a breath of fresh air in Japanese politics, came to be regarded as increasingly ineffective. "We got a regrettable result," Noda said. "The result is everything in the politics. The biggest responsibility lies on me. I will quit as the partly leader of DPJ." The move clears the way for the return to power of former Prime Minister Shinzo Abe, the current leader of the conservative-leaning Liberal Democratic Party, or LDP. "The Japanese people will be keenly looking whether the LDP can meet with their expectations," Abe said in interviews after the polling. The LDP ruled the country almost continuously since its establishment in 1955 until it was forced from power three years ago by the DPJ. Public broadcaster NHK said the LDP and its coalition partner, the new Komei party, gained at least 302 seats in the 480-seat lower house. CNN's main affiliate, TV Asahi, reports the LDP/Komei coalition gained at least 312 seats. The official count is expected to be released Monday. The LDP is inheriting a struggling economy, regional tensions and questions over Japan's role in Asia. "The economy is at the bottom. It's our first mission to turn it around," Abe said.

Does the response "Order a military coupe" correctly answer the question "What did Prime Minister Yoshihiko Noda pledge to do after conceding defeat in parliamentary elections"?

Input: The after-action review had treated the CIA as the lead agency for any offensive against al Qaeda, and the principals, at their March 10 meeting, had endorsed strengthening the CIA's capability for that role. To the CTC, that meant proceeding with "The Plan," which it had put forward half a year earlier-hiring and training more case officers and building up the capabilities of foreign security services that provided intelligence via liaison. On occasion, as in Jordan in December 1999, these liaison services took direct action against al Qaeda cells. In the CTC and higher up, the CIA's managers believed that they desperately needed funds just to continue their current counterterrorism effort, for they reckoned that the millennium alert had already used up all of the Center's funds for the current fiscal year; the Bin Laden unit had spent 140 percent of its allocation. Tenet told us he met with Berger to discuss funding for counterterrorism just two days after the principals' meeting. While Clarke strongly favored giving the CIA more money for counterterrorism, he differed sharply with the CIA's managers about where it should come from. They insisted that the CIA had been shortchanged ever since the end of the Cold War. Their ability to perform any mission, counterterrorism included, they argued, depended on preserving what they had, restoring what they had lost since the beginning of the 1990s, and building from there-with across-the-board recruitment and training of new case officers, and the reopening of closed stations. To finance the counterterrorism effort, Tenet had gone to congressional leaders after the 1998 embassy bombings and persuaded them to give the CIA a special supplemental appropriation. Now, in the aftermath of the millennium alert, Tenet wanted a boost in overall funds for the CIA and another supplemental appropriation specifically for counterterrorism. To Clarke, this seemed evidence that the CIA's leadership did not give sufficient priority to the battle against Bin Laden and al Qaeda. He told us that James Pavitt, the head of the CIA's Directorate of Operations, "said if there's going to be money spent on going after Bin Laden, it should be given to him. My view was that he had had a lot of money to do it and a long time to do it, and I didn't want to put more good money after bad." The CIA had a very different attitude: Pavitt told us that while the CIA's Bin Laden unit did"extraordinary and commendable work," his chief of station in London "was just as much part of the al Qaeda struggle as an officer sitting in [the Bin Laden unit]." The dispute had large managerial implications, for Clarke had found Ailies in the Office of Management and Budget (OMB).

Does the response "The effort of Tenet to give boost to CIA" correctly answer the question "What was the "evidence" in sentence 11 referring to?"?

Input: Static electricity is like a teeter-totter. What happens if a teeter-totter is balanced? Correct! It does not move. What about when its not balanced? Yes, it will now begin to move. Charges move when they are not balanced. Charges can build up by friction. Maybe you rub your feet on a wool mat or carpet. Rubber soled shoes readily gain charges. The wool carpet easily gives up charges. The two items become unbalanced. One item has a positive charge. The other has a negative charge. The difference in charge is called static electricity. Just like the teeter-totter, something is going to move. Positive charges build up on the mat. Negative charges build up on you.

Does the response "Negative" correctly answer the question "What two types of charges build up in unbalanced items?"?
