question:
Article: The oldest and hardest cow beef may be made as tender and tasty as young and choice met. "This declaration was made by the French physicist Denis Papin in book published in 1681, which described his "New Digester" or pressure cooker. It was a cast iron pot with an air-tight lid, which allowed liquids to boil at a higher temperature than usual, and so it cooked food in a quarter of the time. The food was cooked by pressurized steam being forced through it at about 121degC. All pressure cookers were made of cast iron until 1905, when the first aluminum model was made in America. In 1938, Alfred Vischer, a man from Chicago, U. S. A., designed a simple interlocking pan and lid, and an improved pressure-tight seal --a replaceable rubber sealing ring. When Vischer's patent expired in 1954, many companies entered the field, and the rapid pressure cooker became popular with people with people who had little time to cook or had to supply food for unexpected guests.
Answer: 200
answer:
From the passage we can learn pressure cooker made of cast iron lasted at least _ years.

Article: We know that the earth has become warmer over the last century. The Intergovernmental Panel on Climate Change (IPCC), a group established by the World Meteorological Organization and the United Nations Environment Program, reports that the average surface temperature of the earth has increased during the twentieth century by 0.6deg _ 0.2degC.(The _ 0.2degC means that the increase might be as small as 0.4degC or as great as 0.8degC). This may seem like a small shift, but although regional and short--term temperatures do fluctuate over a wide range, global temperatures are generally quite stable. In fact, the difference between today's average global temperature and the average global temperature during the last Ice Age is only about 5 degrees C. Indeed, it's warmer today around the world than at any time during the past 1,000years, and the warmest years of the previous century have occurred within the past decade. We also know that human activities--primarily the burning of fossil fuels--have increased the greenhouse gas content of the earth's atmosphere significantly over the same period. Carbon dioxide is one of the most important greenhouse gases, which trap heat near the planet's surface. The vast majority of climate researchers agree with these overall findings. The scientific disagreements that do still exist primarily concern detailed aspects of the processes that make up these largely accepted general themes. You can think of this website as a window into the world of scientific research. In this primer, you'll find a general discussion of the physical processes underlying the earth's climate, an outline of the kinds of data that may shed light on how the climate is changing--and the role of human activity in these changes--and a description a some of the questions and uncertainties that researchers continue to explore. This primer is organized into four interconnected sections: the Atmosphere; the Hydrosphere ; the Cryosphere ; and the Biosphere .
Answer: engages in the climate and changes about the earth.
answer:
We know from the text that "IPCC" _ .

question:
Article: An endangered deer with vampire-like fangs was spotted for the first time in nearly 60 years, in a remote forest in northeastern Afghanistan. The fanged creature is known as the Kashmir musk deer, and it is native to the Himalayas of northern India, Pakistan's Kashmir region and northern Afghanistan. Only the male deer have fangs, and they use them during mating season to compete for females. A team of researchers scoured Afghanistan's Nuristan province during 2008 and 2009, and recorded five sightings of the animal. This was the first time the species had been spotted since 1948. During the survey, the researchers spotted a single male Kashmir musk deer near the same area three separate times. The researchers also recorded one female and her baby, and saw a second single female that they think may have been the same deer, without her baby. These musk deer are classified as an endangered species on the International Union for Conservation of Nature's Red List. Musk-deer meat is a local delicacy, but the species is mostly hunted for its scent glands that are more valuable by weight than gold -- some believe the glands have pharmaceutical properties, and they sell for nearly $20,455 per pound ($45,000 per kilogram) on the black market, according to the International Union for Conservation of Nature. Three decades of war have ravaged Nuristan province, and the continued violence and political instability make the black-market trade of scent glands uncontrollable. Furthermore, the species is quickly losing suitable habitat. All of the musk deer were spotted on sheltered rocky outcrops around 9,843 feet (3,000 meters) high. In the summer, they regularly trek along steep slopes that make them almost impossible to approach and keep them ly safe from hunters. However, heavy snowfall in the winter drives the species farther down, to more human-accessible slopes, and hunters come from all over the country to stalk the deer for their valuable scent glands. Due to violence and unrest, nongovernmental organizations like the Wildlife Conservation Society have not been able to operate in the Nuristan province since 2010. The WCS maintains contact with locals they have trained to survey and search for the musk deer. Once the situation in Nuristan improves, the WCS intends to return to the area to continue research and to formulate a conservation plan.
Answer: beat for females
answer:
Male deer use fangs in mating season to _ .
