Question: Problem: An archaeological party explore some caverns underground .  Dr. Campbell and Dr. Hughes are the two leaders of the archaeological expedition , and get separated .  While Dr. Hughes finds an alien corpse with a fossilized diamond , Dr. Campbell finds hieroglyphics at the cost of the party except for Hughes and himself .  Two years later , Campbell and his assistant Holly are digging up the bones of Yonggary , a gargantuan dinosaur 50 times the size of a tyrannosaurus rex .  Out of nowhere , people slowly are being killed around the site .  While Holly is working Dr. Hughes , who has been legally dead for 2 years , goes to Holly and tells her to stop the dig .  Dr. Campbell comes into the tent and sends Dr. Hughes off .  Holly quits the expedition when another `` Accident '' occurs .  In the town bar , Dr. Hughes finds Holly and takes her back to her Hotel room to tell her why he thinks the bones of the Dinosaur , Which he calls Yonggary , are going to bring the end of the world .  After explaining , Holly and Hughes go to the site to stop Campbell but it is too late and Aliens resurrect Yonggary .  After Yonggary's first appearance , the Army comes in and takes Holly and Campbell to an army base when Yonggary is dispatched by the aliens again .  The army sends choppers after Yonggary , but he destroys them .  Yonggary is then sent to the city and does some damage , where some jets attack him .  Then Yonggary is transported to a power plant where he is attacked by rocket pack soldiers .  During the fight , Hughes and Holly find out that the diamond on Yonggary's forehead is the device giving the aliens control of Yonggary .

Question:
Right after the Pentagon was hit, NEADS learned of another possible hijacked aircraft. It was an aircraft that in fact had not been hijacked at all. After the second World Trade Center crash, Boston Center managers recognized that both aircraft were transcontinental 767 jetliners that had departed Logan Airport. Remembering the "we have some planes" remark, Boston Center guessed that Delta 1989 might also be hijacked. Boston Center called NEADS at 9:41 and identified Delta 1989, a 767 jet that had left Logan Airport for Las Vegas, as a possible hijack. NEADS warned the FAA's Cleveland Center to watch Delta 1989. The Command Center and FAA headquarters watched it too. During the course of the morning, there were multiple erroneous reports of hijacked aircraft. The report of American 11 heading south was the first; Delta 1989 was the second. NEADS never lost track of Delta 1989, and even ordered fighter aircraft from Ohio and Michigan to intercept it. The flight never turned off its transponder. NEADS soon learned that the aircraft was not hijacked, and tracked Delta 1989 as it reversed course over Toledo, headed east, and landed in Cleveland. But another aircraft was heading toward Washington, an aircraft about which NORAD had heard nothing: United 93. United Airlines Flight 93 FAA Awareness. At 9:27, after having been in the air for 45 minutes, United 93 acknowledged a transmission from the Cleveland Center controller. This was the last normal contact the FAA had with the flight. Less than a minute later, the Cleveland controller and the pilots of aircraft in the vicinity heard "a radio transmission of unintelligible sounds of possible screaming or a struggle from an unknown origin." The controller responded, seconds later: "Somebody call Cleveland?"This was followed by a second radio transmission, with sounds of screaming.  After reading the above, is "9:27 a.m" the correct answer to the question "At what time was the FAA's last normal communication with United Airlines flight 93?"? OPTIONS:
- no
- yes

Answer:
yes
Input: Surely, you have noticed the tall poles along the roadside. Do you know what is on top of those poles? Thats right, wires that carry electric current. These wires carry electric current to your home. But what is electric current? Electric current is actually the flow of electrons. You may recall, an electron is the outer-most particle in an atom. They have a negative charge. Electricity is the continuous flow of these particles. Electrons are able to move through wires. Their speed can even be measured. The SI unit for electric current (or speed) is the ampere (A). Ampere is often shortened to amp. Electric current may flow in just one direction, or it may keep reversing direction. Direct current (DC) flows in only one direction. Direct current is what is used in devices like flashlights. Alternating current (AC) flows in two directions. This is the type of current that flows into your home through wires. 
"What is on top of the poles on the roadside?" is "Wires"?

OPTIONS:
- no
- yes
Output: yes
Input: Rough surfaces create more friction than smooth surfaces. Thats why cars have tires. Its also why we use rubber mats in areas that might get wet. In your bathtub, you may even use No-Slip tape. No-slip is another way of saying the items has a lot of friction. In Figure 1.9, the blades of the skates are very smooth. Thats why you cant slide across ice with shoes. The soles of your shoes are much rougher than skates. The rougher surface of shoes causes more friction and slows you down. Heavier objects also have more friction. A heavy object presses down with more force. The surfaces are held together more tightly. This makes the surfaces harder to slide past each other. Did you ever try to push something heavy across the floor? Heavy objects are much harder to push than light objects. 
"Why do cars have tires?" is "To create friction and hold them to the road"?

OPTIONS:
- no
- yes

Answer: yes
