Question:
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. After reading the above, is "Negative charges" the correct answer to the question "What two types of charges build up in unbalanced items?"?

Answer:
no

Question:
You may be wondering, how can a glacier get so big? Why does it move? These are both good questions. In the winter months, precipitation falls as snow. This solid form of water builds up on the ground as long as the temperatures stay cold enough. As the temperature rises, the snow starts to melt. The frozen water changes state back into a liquid state. Nearer the poles, summer does not last very long. If the summer is long enough and warm enough, all the snow may melt. This is what typically happens now. The earth was a little cooler 12,000 years ago. As a result, during the summer months, that amount of snow did not melt. It may have only been an inch or so of snow that melted. The following winter, snow fell on top of this left-over snow. This next winters snowfall had a head start. Year after year, the snow that did not melt became thicker and thicker. Inch by inch the snow started to build up. Over many years, layer upon layer of snow compacted and turned to ice. After reading the above, is "The earth was a little cooler" the correct answer to the question "Why didn't most snow melt in the past?"?

Answer:
yes

Question:
While this process moved along, diplomacy continued its rounds. Direct pressure on the Taliban had proved unsuccessful. As one NSC staff note put it, "Under the Taliban, Afghanistan is not so much a state sponsor of terrorism as it is a state sponsored by terrorists." In early 2000, the United States began a high-level effort to persuade Pakistan to use its influence over the Taliban. In January 2000, Assistant Secretary of State Karl Inderfurth and the State Department's counterterrorism coordinator, Michael Sheehan, met with General Musharraf in Islamabad, dangling before him the possibility of a presidential visit in March as a reward for Pakistani cooperation. Such a visit was coveted by Musharraf, partly as a sign of his government's legitimacy. He told the two envoys that he would meet with Mullah Omar and press him on Bin Laden. They left, however, reporting to Washington that Pakistan was unlikely in fact to do anything," given what it sees as the benefits of Taliban control of Afghanistan." President Clinton was scheduled to travel to India. The State Department felt that he should not visit India without also visiting Pakistan. The Secret Service and the CIA, however, warned in the strongest terms that visiting Pakistan would risk the President's life. Counterterrorism officials also argued that Pakistan had not done enough to merit a presidential visit. But President Clinton insisted on including Pakistan in the itinerary for his trip to South Asia. His one-day stopover on March 25, 2000, was the first time a U.S. president had been there since 1969. At his meeting with Musharraf and others, President Clinton concentrated on tensions between Pakistan and India and the dangers of nuclear proliferation, but also discussed Bin Laden. President Clinton told us that when he pulled Musharraf aside for a brief, one-on-one meeting, he pleaded with the general for help regarding Bin Laden." I offered him the moon when I went to see him, in terms of better relations with the United States, if he'd help us get Bin Laden and deal with another issue or two." The U.S. effort continued. After reading the above, is "The tensions between India and Pakistan" the correct answer to the question "Why did the Secret Service and the CIA think it was a bad idea to visit Pakistan?"?

Answer:
no

Question:
The modern Republic of Turkey dates only from 1923, but the history of the land within its borders stretches back to the dawn of humanity. Widespread finds of Stone Age implements in cave excavations show that Anatolia was already inhabited during the Middle of the Palaeolithic period (about 200,000 to 40,000 years ago). By Neolithic times, organized communities had arisen, such as the one at Catalhoyuk, near Konya, Turkey's most important prehistoric site. This town, which flourished between 6500 and 5500 b.c. , had flat-roofed houses of mud and timber decorated with wall-paintings, some of which show patterns that still appear on Anatolian kilims. The advent of the Bronze Age (about 3200 b.c. ), and the spread of city-states ruled by kings, is marked by the appearance of royal tombs containing bronze objects in such places as Troy in the west, and Alacahoyuk near Ankara. Around this time the Sumerian civilization living in Mesopotamia (the region between the Tigris and Euphrates rivers in present-day Iraq) founded and developed the cuneiform script, the world's oldest form of writing on record. The technique was introduced by Assyrian traders 1,000 years later into Anatolia, where it was quickly adopted by the indigenous Hatti people, who, at this point, had already reached an advanced state of civilization. The Hittites: The capital of the Hatti was Kanesh (modern Kultepe, near Kayseri). Cuneiform tablets found here record the arrival in Anatolia of warlike invaders around the second millennium b.c. Their origins remain a mystery (their written language was finally deciphered in 1915), but they came from the direction of the Caucasus mountains, spreading destruction and disorder throughout Anatolia. It was two hundred years before they were firmly entrenched in their newly conquered empire. The newcomers were the Hittites, and their domination of Anatolia can be divided into three distinct periods: the Old Kingdom (c. 16001450 b.c. ), then the New or Empire Period (c. 14501200 b.c. ), and the Late Hittite Period (c. After reading the above, is "Turkey's least important prehistoric site" the correct answer to the question "How could one describe Catalhoyuk, near Konya?"?

Answer:
no
