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.
"What is friction?" is "The exchange of molecules"?
Output: no
Input: The documentary portrays a behind-the-scenes look at the poor state of Argentina's civil aviation , and puts the blame on the Argentine Air Force . The Air Force has been in control of air traffic operations since the military takeover of General Juan Carlos Ongan a in 1966 . The producer/director , Enrique Pi eyro , claims Argentina and Nigeria are the only countries whose air force controls and regulates the airline industry . Pi eyro , a former Argentine airline pilot , makes his case in the documentary using diagrams , 3D animations , interviews , hidden cameras in the control tower , and a few props . For example , at one point he spills out a bag of plastic airplanes and equates it to the number of planes the air force has lost due to negligence . The film is heavily based on the Austral L neas A reas Flight 2553 plane crash . Enrique Pi eyro takes his camera , secretly , into the control tower of the Ministro Pistarini International Airport also-known-as Ezeiza , the international airport at Buenos Aires .
"What are two main issues that indicate the "poor state" of Argentina's civil aviation?" is "Several planes lost due to negligence and the Flight 2553 plane crash"?
Output: yes
Input: Elettra stuck the little slip of paper, on which the recipe was written, into her shabby pocket-book without looking at it. She could read and write fairly well, and had been used to helping her husband the under-steward with his accounts at Muro, but even if she had looked at the recipe she would have understood nothing of the doctor's hieroglyphics and abbreviated Latin words. The prescription was for a preparation of arsenic, which Matilde had formerly taken for some time. The chemist would not make any difficulty about preparing twenty doses of it for the Countess Macomer, though the whole quantity of arsenic contained in so many would probably be sufficient to kill one not accustomed to the medicine, if taken all at once. But though Matilde was so anxious to have the stuff before luncheon, she had a number of doses of it put away in a drawer, which she took out and counted, after Elettra had gone. She opened one of the little folded papers and looked at the fine white powder it contained, took a little on the end of her finger and tasted it. Then, from the same drawer, she took a package done up in coarser paper, and opened it likewise, looked at it, smelt it, and touched it with the tip of her tongue very cautiously indeed. It was white, too, but coarser than the medicine. She was very careful in tasting it, and she immediately rinsed her mouth with water, before she tied up the package again, shut the drawer, and put the key into her pocket.
"Who could read and write fairly well?" is "Muro"?
Output:
no
