Input: Renewable Energy Resource Sunlight Sunlight can be used to heat homes. It can also be used to produce electricity. This conversion is made possible by solar cells. However, solar energy may not always be practical. Some areas are just too cloudy. Example Solar panels on the roof of this house generate enough electricity to supply a familys needs. Moving Water Falling water can have a lot of energy. Its energy can be converted into kinetic energy. This energy can turn a turbine and generate electricity. The water may fall naturally over a waterfall or flow through a dam. A drawback of dams is that they flood land upstream. They can also reduce water flow downstream. Either effect may harm ecosystems. Wind Wind is moving air. It has kinetic energy that can do work. Wind turbines change the kinetic energy of the wind to electrical energy. Only certain areas of the world get enough steady wind. Many people also think that wind turbines are noisy and not very nice to look at.

Does the response "Solar cells are used to produce electricity from sunlight" correctly answer the question "How does sunlight create electricity"?

Input: How would the universe look without gravity? It would have no planets and no stars. Thats how it looked when it was young. When the universe was young, there was only gas and dust. From this gas and dust, everything we now see was made. How were stars and planets created from just gas and dust? The answer is gravity. The same gravity that holds you down on Earth. The same force that causes your pencil to roll off your desk. The same force that causes it to fall to the floor. The invisible force of gravity caused dust and gas particles to be pulled together. This force is what formed all the objects in our solar system. This force formed the smallest moons. It also formed our Sun. This force caused more than just our solar system to form. It caused all the other solar systems to form. It caused the formation of all the galaxies of the universe.

Does the response "It helped in the formation of dust and gas" correctly answer the question "What did role did gravity play in the creation of the universe?"?

Input: At the conference room table was White House Deputy Chief of Staff Joshua Bolten. Bolten watched the exchanges and, after what he called "a quiet moment,"suggested that the Vice President get in touch with the President and confirm the engage order. Bolten told us he wanted to make sure the President was told that the Vice President had executed the order. He said he had not heard any prior discussion on the subject with the President. The Vice President was logged calling the President at 10:18 for a twominute conversation that obtained the confirmation. On Air Force One, the President's press secretary was taking notes; Ari Fleischer recorded that at 10:20, the President told him that he had authorized a shootdown of aircraft if necessary. Minutes went by and word arrived of an aircraft down in Pennsylvania. Those in the shelter wondered if the aircraft had been shot down pursuant to this authorization. At approximately 10:30, the shelter started receiving reports of another hijacked plane, this time only 5 to 10 miles out. Believing they had only a minute or two, the Vice President again communicated the authorization to "engage or "take out" the aircraft. At 10:33, Hadley told the air threat conference call: "I need to get word to Dick Myers that our reports are there's an inbound aircraft flying low 5 miles out. The Vice President's guidance was we need to take them out." Once again, there was no immediate information about the fate of the inbound aircraft. In the apt description of one witness, "It drops below the radar screen and it's just continually hovering in your imagination; you don't know where it is or what happens to it." Eventually, the shelter received word that the alleged hijacker 5 miles away had been a medevac helicopter. Transmission of the Authorization from the White House to the Pilots The NMCC learned of United 93's hijacking at about 10:03. At this time the FAA had no contact with the military at the level of national command. The NMCC learned about United 93 from the White House.

Does the response ""three seconds"" correctly answer the question "Approximately how much time passed between when The Vice President was logged calling the President, and when the shelter first received reports of another hijacked plane?"?

Input: Rakal, her first officer, was staring pensively at his panel. He was what this was all about. She watched his graceful fingers ending in thick black claws tap out calculations on the panel. His pointed ears swiveled back and forth, catching every sound from the bridge, while his long tail swished to the rhythm of his thoughts. Only those of the Arrallin Insurrection inner team knew he was no common 'beta furry'. His silken fur, which would be tawny golden and striped with jet black bands, was dyed perfectly to a pure black, and his mane trimmed and thinned as to be indistinguishable from the rest of his coat. His eyes had been treated and darkened to a rich purple to disguise the brilliant golden yellow color that would mark him as an Alpha Arrallin, and leader of his hive. Right now, he looked like an overgrown wolf who'd learned touch-typing. The scout ship re-emerged from the hole - a brilliant speck emerging from a sphere of velvety blackness. It's hail crackled across the comm, and Tara spun to retake her seat at the helm. "Launch the second probe. Won't Central be crushed to learn that another gateway has yielded little more than a class F planet and a white dwarf system. Level 1 and 2 staffers should prepare to be briefed and move out. This sounds like it's the one." The distinctive whuffle of pleasure rippled through the betas on the bridge, and Rakal let loose a small growl, as if to caution his charges against false hope. They'd scouted twenty-seven gates so far, and none had turned up anything worth the Insurrection's time. Tara would not let giddy hopes drag them onto a rock that would spell the end for the project, and the Arrallin species.

Does the response "They had false hope" correctly answer the question "Why were the betas excited on the bridge?"?
