Input: Force is a vector. What then is a vector? Think about how you would give directions to a friend. You would not say, just walk half a mile. The person may walk a half mile in the wrong direction! More information is needed. You may say, follow this particular road for a half mile. You may say, look for the green house on Sumter St. In both examples, you provided a direction. You also gave the distance. In other words, you provided a vector. You did not just give a distance. Both pieces of information are needed to find a location. This is just like describing forces. To explain forces, both size and direction are needed. Notice the girl in Figure 1.1. She is pushing the swing away from herself. Thats the direction of the force. She can give the swing a strong push or a weak push.
"What is the direction of force in which the girl is pushing a swing in Figure 1.1?" is "Pushing the swing left"?
Output: no
Input: Born in Moscow, Pushkin published his first poem at the age of fifteen. By the time he finished school as part of the first graduating class of the prestigious Imperial Lyceum in Tsarskoe Selo near Saint Petersburg, his talent was already widely recognized within the Russian literary scene. After school, Pushkin plunged into the vibrant and raucous intellectual youth culture of the capital, Saint Petersburg. In 1820 he published his first long poem, Ruslan and Lyudmila, amidst much controversy about its subject and style. Pushkin gradually became committed to social reform and emerged as a spokesman for literary radicals. This angered the government, and led to his transfer from the capital (1820). He went to the Caucasus and to the Crimea, then to Kamenka and Chisinau, where he became a Freemason.
"How did Pushkin become a famous Russian poet?" is "He published his first long poem Ruslan and Lyudmila"?
Output: no
Input: Military Notification and Response. Boston Center did not follow the protocol in seeking military assistance through the prescribed chain of command. In addition to notifications within the FAA, Boston Center took the initiative, at 8:34, to contact the military through the FAA's Cape Cod facility. The center also tried to contact a former alert site in Atlantic City, unaware it had been phased out. At 8:37:52, Boston Center reached NEADS. This was the first notification received by the military-at any level-that American 11 had been hijacked: FAA: Hi. Boston Center TMU [Traffic Management Unit], we have a problem here. We have a hijacked aircraft headed towards New York, and we need you guys to, we need someone to scramble some F-16s or something up there, help us out. NEADS: Is this real-world or exercise? FAA: No, this is not an exercise, not a test. NEADS ordered to battle stations the two F-15 alert aircraft at Otis Air Force Base in Falmouth, Massachusetts, 153 miles away from New York City. The air defense of America began with this call. At NEADS, the report of the hijacking was relayed immediately to Battle Commander Colonel Robert Marr. After ordering the Otis fighters to battle stations, Colonel Marr phoned Major General Larry Arnold, commanding general of the First Air Force and NORAD's Continental Region. Marr sought authorization to scramble the Otis fighters. General Arnold later recalled instructing Marr to "go ahead and scramble them, and we'll get authorities later." General Arnold then called NORAD headquarters to report. F-15 fighters were scrambled at 8:46 from Otis Air Force Base.
"What is the name of the city of the planes departure?" is "Falmouth"?
