Hundreds of thousands of years before China was to become the world's longest-running civilization, the prologue was enacted by means of the flicker of a carefully tended fire. Peking Man, a forebear of Homo sapiens, achieved a mastery of fire. We might call it the first Chinese invention. Not that he devised flint and steel, matches, or any other way of creating fire. Peking Man simply learned how to capture flame, perhaps from a forest fire, and keep it alight. He thus enjoyed two revolutionary luxuries: light and heat. Technologically and sociologically, it was a phenomenal breakthrough: with fire, communities could live year 'round in one cave, in which cooking and even smelting could be pursued. And so, by 600,000 b.c., about 50 km (31 miles) southwest of present-day Beijing, the ancestors of mankind were ready to settle down. Several hundred thousand years later, when Marco Polo reached the capital of China, he was astonished by a further development in fire technology. The Chinese, he announced, used black stones dug out of mountains as fuel. Europeans did not yet have a word for "coal," nor had they discovered a use for it. The First Dynasty The confluence of mythology and history in China took place around 4,000 years ago during what is referred to as the Xia (Hsia) Dynasty. This was still the Stone Age, but the people are thought to have made silk from thread produced by the worms they cultivated on the leaves of their mulberry trees. And written language (which evolved as early as 4,500 to 5,000 years ago) was already in use, originally by oracles and then by official scribesChina's first scholars. During the second of the quasi-legendary dynasties, the Shang (from about the 16th to 11th centuries b.c.), the Chinese developed an interest in art. Careful geometric designs as well as dragon and bird motifs adorned bowls and implements. And with the arrival of the Bronze Age, the Chinese created bronze vessels of such beauty and originality that, until modern times, archaeologists refused to believe they were cast 3,000 years ago. The Shang Dynasty gave rise to the concept of one Chinese nation under one government.

From Babylon, Alexander went to Susa, one of the Achaemenid capitals, and captured its legendary treasury. He sent the bulk of his army to the Persian ceremonial capital of Persepolis via the Royal Road. Alexander himself took selected troops on the direct route to the city. He had to storm the pass of the Persian Gates (in the modern Zagros Mountains) which had been blocked by a Persian army under Ariobarzanes and then hurried to Persepolis before its garrison could loot the treasury. On entering Persepolis, Alexander allowed his troops to loot the city for several days. Alexander stayed in Persepolis for five months. During his stay a fire broke out in the eastern palace of Xerxes and spread to the rest of the city. Possible causes include a drunken accident or deliberate revenge for the burning of the Acropolis of Athens during the Second Persian War.

Question: "During his stay in what city did a fire break out to rest of the area?"

Response: "Persepolis"
OPTIONS:
- no
- yes

Problem: Force is a vector. What then is a vector? Think about how you would give directions to a friend. You would not say, just walk half a mile. The person may walk a half mile in the wrong direction! More information is needed. You may say, follow this particular road for a half mile. You may say, look for the green house on Sumter St. In both examples, you provided a direction. You also gave the distance. In other words, you provided a vector. You did not just give a distance. Both pieces of information are needed to find a location. This is just like describing forces. To explain forces, both size and direction are needed. Notice the girl in Figure 1.1. She is pushing the swing away from herself. Thats the direction of the force. She can give the swing a strong push or a weak push.

Question: "How far is the green house on Sumter St.?"

Answer: "Half an hour distance"

OPTIONS:
- no
- yes
Answer: no

Question:
What a time of it Dawson's Landing was having! All its life it had been asleep, but now it hardly got a chance for a nod, so swiftly did big events and crashing surprises come along in one another's wake: Friday morning, first glimpse of Real Nobility, also grand reception at Aunt Patsy Cooper's, also great robber raid; Friday evening, dramatic kicking of the heir of the chief citizen in presence of four hundred people; Saturday morning, emergence as practicing lawyer of the long-submerged Pudd'nhead Wilson; Saturday night, duel between chief citizen and titled stranger. The people took more pride in the duel than in all the other events put together, perhaps. It was a glory to their town to have such a thing happen there. In their eyes the principals had reached the summit of human honor. Everybody paid homage to their names; their praises were in all mouths. Even the duelists' subordinates came in for a handsome share of the public approbation: wherefore Pudd'nhead Wilson was suddenly become a man of consequence. When asked to run for the mayoralty Saturday night, he was risking defeat, but Sunday morning found him a made man and his success assured. After reading the above, is "President" the correct answer to the question "Besides the duelists, who else received the town's honors?"? OPTIONS:
- no
- yes

Answer:
no

In remarks during a ribbon-cutting ceremony here on Wednesday, Gov. George E. Pataki said he expected the facility to generate thousands more jobs in the Hudson Valley area for contractors and suppliers catering to the factory. He praised IBM for being "a critical partner in our economic development efforts" in New York state. In a brief speech, Samuel J. Palmisano, IBM's chief executive, emphasized that it was important to make long-term investments despite the current slump in the technology business. "To play to win in technology, you innovate and you lead," he said. But manufacturing technology products is a costly and cyclical business. In June, IBM announced that it was taking a charge of more than $2 billion against earnings. The largest single reasons for the charge were the cost of getting out of the business of manufacturing hard disks for storage, which it sold to Hitachi, and closing down some of its older semiconductor operations. But Kelly said the demand for advanced chips, like those produced at IBM's facility in Burlington, Vt., is strong. "I need more capacity in that end of the market," he said, "and this is factory is critical to meeting that growing demand." If IBM has miscalculated the demand, it will suffer badly as both the high operating costs and depreciation on the huge capital investment for the East Fishkill factory drag down earnings. But industry analysts said the plant should be insulated from a falloff in one or a few segments of the semiconductor market.

Question: "What was the main reason IBM gave for putting $2 billion dollars against earnings?"

OPTIONS:
- no
- yes

Answer: "The cost o getting out of the business of manufacturing hard disks for storage and closing down some of its older semiconductor operations"
