Input: Plants also detect the daily cycle of light and darkness. Do you know how plants respond to these changes? Some plants open their leaves during the day. It is during these hours the plant can collect sunlight. At night, the plant closes its leaves to prevent water loss. Many plants respond to the change in the length of the day. As days grow shorter, some plants respond by going dormant. Dormant is when a plant suspends its growth. It does this in order to survive. Shorter days signal the coming of winter. Winter in most areas means extreme cold. It is also very dry in the winter months. As winter approaches, some plants respond by their leaves changing color. After the change in color, they fall off. This dormancy period helps trees. It allows them to survive the cold and dry winter. Plants only want to grow when conditions are right. 

Does the response "They collect sunlight on open leaves in the day and close them at night to prevent water loss" correctly answer the question "How do plants respond to changes in light conditions during the day and night?"?

Input: When a stream or river slows down, it starts dropping its sediments. Larger sediments are dropped in steep areas. Some smaller sediments can still be carried by a slow moving stream or river. Smaller sediments are dropped as the slope becomes less steep. Alluvial Fans In arid regions, a mountain stream may flow onto flatter land. The stream comes to a stop rapidly. The deposits form an alluvial fan. Deposition also occurs when a stream or river empties into a large body of still water. In this case, a delta forms. A delta is shaped like a triangle. It spreads out into the body of water. 

Does the response "Delta" correctly answer the question "What type of feature is formed when mountain streams in arid regions flow onto flatter land and the stream comes to a rapid stop?"?

Input: 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. 

Does the response "Getting out of the business of manufacturing hard disk for storage" correctly answer the question "What was the main reason IBM gave for putting $2 billion dollars against earnings?"?

Input: 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 scribes — China'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. 

Does the response "China" correctly answer the question "Peking Man achieved a mastery of fire in what is currently which nation?"?
