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 "A magnetic force is exerted over a distance" the correct answer to the question "How do magnets exert force?"?

Answer:
yes

Question:
Water flowing over Earths surface or underground causes erosion and deposition. Water flowing over a steeper slope moves faster and causes more erosion. How water transports particles depends on their size. When water slows down, it starts depositing sediment. This process starts with the largest particles first. Runoff erodes the land after a heavy rain. It picks up sediment. Runoff carries most of the sediment to bodies of water. Mountain streams erode narrow, V-shaped valleys and waterfalls. Erosion and deposition by slow-flowing rivers create broad floodplains and meanders. Deposition by streams and rivers may form alluvial fans and deltas. Floodwaters may deposit natural levees. Erosion and deposition by groundwater can form caves and sinkholes. Stalactites and stalagmites are mineral deposits. They build up in caves as water continues to drip. After reading the above, is "Stalactites" the correct answer to the question "What kind of deposits build up in caves as water continues to drip?"?

Answer:
yes

Question:
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. After reading the above, is "By climbing on top of a tree" the correct answer to the question "How did the Princess spot the castle?"?

Answer:
yes

Question:
(CNN) -- Cuba will pardon more than 2,900 prisoners, the government said Friday, though U.S. subcontractor Alan Gross is not among those who will be freed. The decision to release the prisoners follows "numerous requests" from their family members and religious institutions, and is a humanitarian gesture, said Cuban President Raul Castro. Among those who might be freed are prisoners over the age of 60, along with those who are sick, female or young with no previous criminal record. With some exceptions, prisoners convicted of spying, terrorism, murder and drug trafficking will not be released. Those who will be freed have already served a "important" part of their sentences and exhibited good behavior, according to an official statement published on the state-run website Cubadebate. The jailed American, Gross, will not be among those pardoned, the Cuban Interests Section in Washington said. Gross was jailed in December 2009, when he was working as a subcontractor on a U.S. Agency for International Development project aimed at spreading democracy. Castro has accused him of importing satellite equipment to connect dissidents to the Internet, and this year Cuba's highest court upheld the 15-year sentence imposed on Gross for committing crimes against the security of the state. He has maintained his innocence and said he was trying to help connect the Jewish community to the Internet. Castro, speaking to the National Assembly, said that 86 prisoners from 25 countries would be among those released in coming days. He cited the upcoming visit of Pope Benedict XVI as one of the motivations behind the move, which he said showed the "generosity and strength of the revolution." The pope has said he plans to visit Mexico and Cuba before Easter. After reading the above, is "Most of the prisoners over the age of 60, along with those who are sick, female or young with no previous criminal record" the correct answer to the question "Why is the decision to release 2900 Cuban prisoners considered by Cuban President Raul Castro a "humanitarian gesture"?"?

Answer:
yes
