Input: Sometimes traits can vary from parent to offspring. These changes are due to mutations. Mutations are a random change. Mutations are natural. Some mutations are harmful. In this case, the organism may not live to reproduce. The trait will not be passed onto offspring. Others variations in traits have no effect on survival. Can some mutations be good for a living thing? Other mutations can have great benefits. Imagine being the first moth that can blend into its background. It would have a better chance of survival. A living thing that survives is likely to have offspring. If it does, it may pass the new trait on to its offspring. Thats good news for the offspring. The offspring may be more likely to survive. Mutations are one way living things adapt to new conditions.

Does the response "Are alterations to a DNA sequence" correctly answer the question "What are mutations?"?

OPTIONS:
- no
- yes

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: "How does knowledge of reflection help pool players?"

OPTIONS:
- no
- yes

Answer: "They need it before swimming in a pool."

Response: no

Once upon a time there was a princess who lived in a high tower and she was not allowed to leave because of her mean mother. One day she chose to leave but her mother would not let her. The princess climbed out the window of the high tower and climbed down the south wall when her mother was sleeping. She wandered out a good ways. Finally she went into the forest where there are no electric poles but where there are some caves. There she met a young man who was running. His name was John. John asked the princess why such a beautiful woman like her was out in the middle of a forest. She said that she had been trapped for her whole life by an evil woman who said she was her mother. The man said that he would take the princess to a castle that was near. He also said that he thought that she may be the missing princess. As they go through the forest they run into many problems. They see that they are lost and have no way of finding where to go. After several days pass, the princess climbs up to the top of a tree in order to find out where they are. She sees that the castle where they want to go is not that far away and near a mountain. After thinking of the best way to get there, John and the princess go to the castle where they live for the rest of their lives.

Question: "How did the Princess spot the castle?"

Response: "By climbing on John's shoulders"

Problem: 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.

Question: "When Grim disappeared upstairs for 10 minutes, who did he come down disguised as?"

Answer: "He came down disguised as a Shereefian officer--that is to say, of Emir Feisul's Syrian army"

Question:
Magnets are able to place a force on certain materials. This force is called a magnetic force. The force a magnet exerts is a little different from the forces you may normally think about. You exert a force on a book when you lift it. You also exert a force on the pedals of your bicycle. In both those cases, those forces cause a change. The change you see in both these cases is called motion. Magnets, too, can produce change. They can produce motion just like you do. Unlike you, magnets do not have to touch something to exert a force. A magnetic force is exerted over a distance. Thats right, a magnet can push or pull certain items without ever touching them. Thats how the maglev train works. Do you know another type of force that does not require objects to touch? These forces are known as non-contact forces. Another type of non-contact force you may be familiar with is gravity. Gravity too can cause changes in motion. Gravity holds our moon in orbit without touching it. After reading the above, is "Magnets do not have to touch something to exert a force" the correct answer to the question "How do magnets produce change?"? OPTIONS:
- no
- yes

Answer:
yes

You approach the door of your friends house. What is the first thing you do before entering? Of course, you wipe your feet. You are a thoughtful visitor. Fortunately, there is a nice piece of carpet by the door to wipe your shoes. Too bad your caring comes at a price. After wiping your feet on the mat you reach out to touch the brass knocker on the door. A spark suddenly jumps between your hand and the metal. You feel an electric shock. Why do you think an electric shock occurs? An electric shock occurs when there is a sudden discharge of static electricity. Has this ever happened to you? You reached out to touch a metal doorknob and received an unpleasant electric shock? The reason you get a shock is because of moving electric charges. Moving electric charges also create lightning bolts. It is also the same reason electric current flows through cables and wires.

Question: "You get shocked because of moving electric charges and moving electric charges also creates what?"

Response: "Short circuit"
OPTIONS:
- no
- yes

A:
no
