Problem: Light rays strike a reflecting surface. They are then reflected back. You can predict the angle of the reflected light. Imagine a ball bouncing off a surface. Light can do the same thing. That is, assuming the surface is shiny. So how do you know where light will go after it strikes a shiny surface? It depends on how the light initially strikes the shiny object. Light does not always go straight toward a surface. Therefore, not all light bounces straight back. Sometimes, light can hit a surface at an angle. The angle at which it strikes the surface tells us how it will bounce off. While light is different to a ball, they react in a similar manner. Many sports rely on knowledge of reflection. Pool players know a lot about reflection. They take great care when they strike the pool ball. They need it to go to a certain place. They know the angle it will hit the side of the pool table.

Question: "What type of people know alot about reflection?"

Answer: "All the people in sports."

OPTIONS:

Question:
It is not enough to describe some objects by their location. We may also need to know its direction. For example, a wind blows a storm over your school. Where is that storm coming from? Where is it going? How can we describe a direction? The most common way is by using a compass. A compass is a device with a floating needle (Figure 2.1). The needle is a small magnet. The needle aligns itself with the Earth's magnetic field. The compass needle always points to magnetic north. If you have a compass and you find north. You can then know any other direction. See the directions, such as east, south, west, etc., on a compass rose. The Earth has two poles. It has a magnetic north pole. It also has a geographic north pole. These two poles are close to each other but not the exact same place. After reading the above, is "a rod that shows every direction" the correct answer to the question "What is a compass?"? OPTIONS:
- no
- yes

Answer:
no

Input: The side of Malaquez's parcel gave way to reveal a greenmunk caught in a sheen of solid air. Bits of leaf mold flew from under his feet as he ran to greet a friend or a bringer of food. Tasha oohed in awe. I said, "Frodo's been visiting you, eh?" Malaquez said, "Your pet?" "Hardly. He lives around here somewhere. I suppose he was attracted to the commotion up the hill." "Ah," Malaquez said. "Why 'Frodo'?" Tasha said, "A little fellow with big, furry feet. What else could he be called?" She handed the sculpture to me. I almost dropped it; I expected it to weigh no more than a holo. "Heavy," I said, as if he might not have known. He laughed. "My last piece was of four old Undersiders crouched around a trash fire. Be glad someone didn't toss that to you." He spoke of his art with the enthusiasm of a seven-year-old. "Um, I should wait to importune you, but..."
"Where does Frodo live?" is "Tunnels"?

OPTIONS:
- no
- yes
Output: no

Input: Alexander the Great's accomplishments and legacy have been depicted in many cultures. Alexander has figured in both high and popular culture beginning in his own era to the present day. The Alexander Romance, in particular, has had a significant impact on portrayals of Alexander in later cultures, from Persian to medieval European to modern Greek. Alexander may already have considered himself as the "King of Asia" after his victory at Issos, a conception strengthened by his subsequent successes. The conception might have inspired the title given to Alexander in Babylonian documents, "king of the world (since "king of Asia" had no meaning in Babylonian geography). It might also be alluded in the sarcastic comments by Anaxarchus, trying to rouse Alexander after the murder of Cleitus. or in the orator Demades' comments that if Alexander were dead, "The whole world would stink of his corpse". Alexander is called "kosmokrator", ruler of the world, in the later Alexander Romance. Alexander features prominently in modern Greek folklore, more so than any other ancient figure. The colloquial form of his name in modern Greek ("O Megalexandros") is a household name, and he is the only ancient hero to appear in the Karagiozis shadow play. One well-known fable among Greek seamen involves a solitary mermaid who would grasp a ship's prow during a storm and ask the captain "Is King Alexander alive?". The correct answer is "He is alive and well and rules the world!", causing the mermaid to vanish and the sea to calm. Any other answer would cause the mermaid to turn into a raging Gorgon who would drag the ship to the bottom of the sea, all hands aboard.

Does the response "When asked about Alexander being dead or alive, the mermaid would only accept the words, "He is alive and well and rules the world!" This was the only response that would send her back to the depths of the sea without turning into the gorgon full of anger" correctly answer the question "What caused the mermaid within the well known fable to turn into a gorgon?"?

OPTIONS:
- no
- yes

Input: (CNN) -- The U.S. space shuttle program retired in 2011, leaving American astronauts to hitchhike into orbit. But after three long years, NASA's successor is almost ready to make an entrance. Orion, the agency's newest manned spaceship, is being prepared for its first mission in December. In future missions, it will journey into deep space -- to Mars and beyond -- farther than humans have ever gone before. Orion comes loaded with superlatives. It boasts the largest heat shield ever built and a computer 400 times faster than the ones on the space shuttles. It will be launched into space on the most powerful rocket NASA has ever made. No astronauts will be aboard the December flight, which will test the spacecraft's systems for future manned missions. Final work on the spacecraft is under way at the Kennedy Space Center in Florida. Orion came one step closer to completion this month with the stacking of the crew module atop the service module. "Now that we're getting so close to launch, the spacecraft completion work is visible every day," Orion Program Manager Mark Geyer said in a statement. A 3,600-mile journey When complete, the Orion capsule will resemble a fencing foil, with a tall spire shooting up from a rounded base. At the top will sit a launch abort system, with downward-facing thrusters that would save the crew from a jarring crash in the event of a rocket malfunction. The bottom portion, the service module, will perform various functions such as in-space propulsion and cargo storage. Nestled between the two will be the crew module, capable of supporting human life from launch until recovery. Attached to the service module will be a United Launch Alliance Delta IV Heavy rocket. For the first time since the space shuttle's debut launch in 1981, the crew compartment will ride on the tip of the rocket rather than hanging onto its side, evoking the configuration of the famous Apollo or Gemini missions.
"The United Launch Alliance Delta IV Heavy rocket will be attached to what portion of the spaceship?" is "Abort system"?

OPTIONS:
- no
- yes

no
