Question:
You may wonder if there are other examples of static discharge. The answer is yes. Lightning is a form of static discharge. It is much more dramatic than what happens between you and the door knocker, but it is the same principle. You can see how it occurs in the following diagram and animation. You have no doubt seen lightning in a rainstorm. What does lighting have to do with static electricity? As it turns out, everything! During a rainstorm, clouds develop regions of different charges. This happens due to the movement of air molecules, water drops, and ice particles. The negative charges are concentrated at the base of the clouds. The positive charges are concentrated at the top. The negative charges repel electrons on the ground below. The ground then becomes positively charged. Over time the differences increase. Eventually the electrons are discharged. This is what we see as lightning. You can watch an awesome slow-motion lightning strike below. After reading the above, is "Door knocker" the correct answer to the question "What are two examples of static discharge?"? OPTIONS:
- no
- yes

Answer:
yes

Question:
(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. After reading the above, is "Superlatives" the correct answer to the question "The agency's newest manned spaceship comes loaded with what?"? OPTIONS:
- no
- yes

Answer:
yes

Question:
Rivers flowing over gentle slopes move more slowly. They move much more slowly than a mountain stream. These slow moving streams create different types of features than mountain streams. Slow moving water erodes the sides of their channels more than the bottom. Also, large curves in the stream form. These curves are called meanders. Meanders are caused by erosion and deposition. Remember, faster moving water causes erosion more quickly. Slower moving water erodes material more slowly. If water is moving slowly enough, the sediment being carried may settle out. This settling out, or dropping off, of sediment is deposition. The curves are called meanders because they slowly wander over the land. As meanders erode from side to side, they create a floodplain. This is a broad, flat area on both sides of a river. Eventually, a meander may become cut off from the rest of the river. This forms an oxbow lake. After reading the above, is "The bottom" the correct answer to the question "Will water flowing over gentle slopes erode more of the sides of their channels or the bottom?"? OPTIONS:
- no
- yes

Answer:
no

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 "Drug traffickers" the correct answer to the question "Of the 2,900 prisoners, who will not be released?"? OPTIONS:
- no
- yes

Answer:
yes
