Input: You know that friction also causes heat. Think about when you rub your hands together. It is friction that makes them warm. But why does this happen? Friction causes the molecules on rubbing surfaces to move faster. Faster moving particles have more heat energy. Heat from friction can be useful. Can you think of other places where you might find friction? Friction also lets you light a match. Heat from friction can also cause problems. It can cause a car to overheat. To reduce friction, oil is added to the engine. Oil coats the surfaces of moving parts. This coating of oil makes them slippery. When things are slippery there is less friction. Have you ever seen a sign that says, slippery when wet? This too has to do with friction. Water, like oil, can reduce friction. The wet surface may allow your shoes to slide more easily.
"How does oil reduce friction between moving car parts?" is "By making them cold"?

Input: According to the radar reconstruction, American 77 reemerged as a primary target on Indianapolis Center radar scopes at 9:05, east of its last known position. The target remained in Indianapolis Center's airspace for another six minutes, then crossed into the western portion of Washington Center's airspace at 9:10. As Indianapolis Center continued searching for the aircraft, two managers and the controller responsible for American 77 looked to the west and southwest along the flight's projected path, not east-where the aircraft was now heading. Managers did not instruct other controllers at Indianapolis Center to turn on their primary radar coverage to join in the search for American 77. In sum, Indianapolis Center never saw Flight 77 turn around. By the time it reappeared in primary radar coverage, controllers had either stopped looking for the aircraft because they thought it had crashed or were looking toward the west. Although the Command Center learned Flight 77 was missing, neither it nor FAA headquarters issued an all points bulletin to surrounding centers to search for primary radar targets. American 77 traveled undetected for 36 minutes on a course heading due east for Washington, D.C. By 9:25, FAA's Herndon Command Center and FAA headquarters knew two aircraft had crashed into the World Trade Center. They knew American 77 was lost. At least some FAA officials in Boston Center and the New England Region knew that a hijacker on board American 11 had said "we have some planes." Concerns over the safety of other aircraft began to mount. A manager at the Herndon Command Center asked FAA headquarters if they wanted to order a "nationwide ground stop." While this was being discussed by executives at FAA headquarters, the Command Center ordered one at 9:25. The Command Center kept looking for American 77. At 9:21, it advised the Dulles terminal control facility, and Dulles urged its controllers to look for primary targets. At 9:32, they found one. Several of the Dulles controllers "observed a primary radar target tracking eastbound at a high rate of speed" and notified Reagan National Airport. FAA personnel at both Reagan National and Dulles airports notified the Secret Service.

Does the response "Herndon Command Center" correctly answer the question "What target remained in Indianapolis Center's airspace, then crossed into the western portion of Washington Center's airspace at 9:10."?

Even though electronic espionage may cost U.S. firms billions of dollars a year, most aren't yet taking precautions, the experts said. By contrast, European firms will spend $150 million this year on electronic security, and are expected to spend $1 billion by 1992. Already many foreign firms, especially banks, have their own cryptographers, conference speakers reported. Still, encrypting corporate communications is only a partial remedy. One expert, whose job is so politically sensitive that he spoke on condition that he wouldn't be named or quoted, said the expected influx of East European refugees over the next few years will greatly increase the chances of computer-maintenance workers, for example, doubling as foreign spies. Moreover, he said, technology now exists for stealing corporate secrets after they've been "erased" from a computer's memory. He said that Oliver North of Iran-Contra notoriety thought he had erased his computer but that the information was later retrieved for congressional committees to read. No personal computer, not even the one on a chief executive's desk, is safe, this speaker noted. W. Mark Goode, president of Micronyx Inc., a Richardson, Texas, firm that makes computer-security products, provided a new definition for Mikhail Gorbachev's campaign for greater openness, known commonly as glasnost. Under Mr. Gorbachev, Mr. Goode said, the Soviets are openly stealing Western corporate communications. He cited the case of a Swiss oil trader who recently put out bids via telex for an oil tanker to pick up a cargo of crude in the Middle East. Among the responses the Swiss trader got was one from the Soviet national shipping company, which hadn't been invited to submit a bid. The Soviets' eavesdropping paid off, however, because they got the contract.

Question: "Are Europeans spending more or less to combat electronic espionage than the U.S.?"

- no
- yes

Answer: "A lot more"

Problem: You might want to know how cold it is. You may need to know how fast the wind is blowing. Maybe it rained last night? Do you know how much? Does it feel humid to you? You have heard all these questions before. To answer these questions, we need data. That data comes from special tools. These tools collect data about the weather. You can see some of the common tools listed below: A thermometer measures temperature. An anemometer measures wind speed. A rain gauge measures the amount of rain. A hygrometer measures humidity. A wind vane shows wind direction. A snow gauge measures the amount of snow.

Question: "How do we get weather data?"

Answer: "Reports"
