Input: 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.
"How could you measure temperature and humidity?" is "Umbrella"?
Output: no
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 "Friction causes the molecules on rubbing surfaces to move faster"?
Output: yes
Input: Grim disappeared upstairs himself, and returned about ten minutes later in the uniform of a Shereefian officer--that is to say, of Emir Feisul's Syrian army. Nothing could be smarter, not anything better calculated to disguise a man. Disguise, as any actor or detective can tell you, is not so much a matter of make- up as suggestion. It is little mannerisms--unstudied habits that identify. The suggestion that you are some one else is the thing to strive for, not the concealment of who you really are. Grim's skin had been sun-tanned in the Arab campaign under Lawrence against the Turks. The Shereefian helmet is a compromise between the East and West, having a strip of cloth hanging down behind it as far as the shoulders and covering the ears on either side, to take the place of the Arab head-dress. The khaki uniform had just enough of Oriental touch about it to distinguish it from that of a British officer. No man inexperienced in disguise would dream of choosing it; for the simple reason that it would not seem to him disguise enough. Yet Grim now looked so exactly like somebody else that it was hard to believe he was the same man who had been in the room ten minutes before. His mimicry of the Syrian military walk--blended of pride and desire not to seem proud--was perfect.
"What else, besides make-up, makes a good disguise?" is "Clothing"?
Output:
no
