Static electricity is like a teeter-totter. What happens if a teeter-totter is balanced? Correct! It does not move. What about when its not balanced? Yes, it will now begin to move. Charges move when they are not balanced. Charges can build up by friction. Maybe you rub your feet on a wool mat or carpet. Rubber soled shoes readily gain charges. The wool carpet easily gives up charges. The two items become unbalanced. One item has a positive charge. The other has a negative charge. The difference in charge is called static electricity. Just like the teeter-totter, something is going to move. Positive charges build up on the mat. Negative charges build up on you.

Question: "Charges can move when they are unbalanced by what?"

OPTIONS:
- no
- yes

Answer: "Jumping up and down"

Response: no

The highest point of a wave is the crest. The lowest point is the trough. The vertical distance between a crest and a trough is the height of the wave. Wave height is also called amplitude. The horizontal distance between two crests is the wavelength. Both amplitude and wavelength are measures of wave size. The size of an ocean wave depends on how fast, over how great a distance, and how long the wind blows. The greater each of these factors is, the bigger a wave will be. Some of the biggest waves occur with hurricanes. A hurricane is a storm that forms over the ocean. Its winds may blow more than 150 miles per hour! The winds also travel over long distances and may last for many days.

Question: "What do we know about wind from the paragraph?"

Response: "Winds travel over long distances"
OPTIONS:
- no
- yes

Problem: Energy is stored in chemical compounds. This energy is called chemical energy. Chemical energy is a form of potential energy. When bonds between atoms are broken, energy is released. The wood in fireplaces has chemical energy. The energy is released as heat and light when the wood burns. Most living things get their energy from food. When food molecules are broken down, the energy is released. It may then be used to do work, like playing ball or studying science. If you have ever heard, "Eat a good breakfast", thats why. You need energy to do things during the day. To do those things you need energy. You get your energy from the food you eat. That energy is stored in your body until you need it. How did you get to school today? If you walked, you used chemical energy from the food you ate. What if you rode the bus or were driven in a car? Where did that energy come from?

Question: "Where do people get their energy"

Answer: "Food"

Question:
The Mummy 's Shroud is set in 1920 and tells the story of a team of archaeologists who come across the lost tomb of the boy Pharaoh Kah-To-Bey . The story begins with a flash back sequence to Ancient Egypt and we see the story of how Prem , a manservant of Kah-To-Bey , spirited away the boy when his father was killed in a palace coup and took him into the desert for protection . Unfortunately , the boy dies and is buried . The story then moves forward to 1920 and shows the expedition led by scientist Sir Basil Walden and business man Stanley Preston finding the tomb . They ignore the dire warning issued to them by Hasmid , a local Bedouin about the consequences for those that violate the tombs of Ancient Egypt and remove the bodies and the sacred shroud . Sir Basil is bitten by a snake just after finding the tomb . He recovers , but has a relapse after arriving back in Cairo . Preston takes advantage of this and commits him to an insane asylum , to take credit for finding the tomb and Prince 's mummy himself . Meanwhile , after being placed in the Cairo Museum , the mummy of Prem is revived when Hasmid chants the sacred oath on the shroud . The mummy then proceeds to go on a murderous rampage to kill off the members of the expedition , beginning with Sir Basil after he escapes from the asylum . One by one , those who assisted in removing the contents of the tomb to Cairo are eliminated by such grisly means as strangulation , being thrown out of windows , and having photographic acid thrown in their face . After reading the above, is "Prem" the correct answer to the question "Who found the tomb of Kah-To-Bey?"? OPTIONS:
- no
- yes

Answer:
no

Input: Fossils can be used to match up rock layers. As organisms change over time, they look different. Older fossils will look different than younger fossils. Some organisms only survived for a short time before going extinct. Knowing what organisms looked like at certain times also helps date rock layers. Some fossils are better than others for this use. The fossils that are very distinct at certain times of Earths history are called index fossils. Index fossils are commonly used to match rock layers. You can see how this works in Figure 2.30. If two rock layers have the same index fossils, then they're probably about the same age.
"How are fossils used to match up rock layers?" is "They match the water levels"?

OPTIONS:
- no
- yes
Output: no

Chinese Influences: The Japanese were forced out of the Korean peninsula in the sixth century, but not before the Koreans had bequeathed to the Yamato court copies of the sacred images and scriptures of Chinese Buddhism. Just as Christianity introduced Mediterranean culture into northern Europe, so Buddhism brought Chinese culture into Japanese society. Throughout the seventh and eighth centuries numerous Japanese monks, scholars, and artists made the perilous trip west across the Sea of Japan to study Chinese religion, history, music, literature, and paintinglater to be brought back for further development in Japan. An outstanding figure of this time was Prince Shotoku, who in 604 developed the "Seventeen-Article Constitution," outlining a code of human conduct and the ideals of state as a basic law for the nation. He also established relations with the Sui dynasty in China. Through him, the Japanese imperial court developed Chinese patterns of centralized government, with its formal bureaucracy of eight court ranks. The Chinese calendar was used to calculate the year of Japan's foundation by counting back the 1,260 years of the Chinese cosmological cycle. Thus, 660 b.c. is still the official date celebrated nationwide. At this early stage in its history Japan was already (for the most part) only nominally ruled by the emperor. De facto power was exercised by the militarily and economically strongest family. The Sogas had promoted Buddhism as an imperially sanctioned counterweight to the native Shinto religion, along with the new Chinese customs, to weaken the influence of their more conservative rivals. But they in turn were ousted in a.d. 645 by Nakatomi Kamatari, founder of the great Fujiwara clan, which was to rule Japanese affairs for hundreds of years and provide prominent advisers to the emperor even up to the 19th century.

Question: "What year is known as the year of Japan's foundation?"

OPTIONS:
- no
- yes

Answer: "645 a.d"

Response:
no
