Article: Sir Edmund Hillary is best known for being the first, along with climbing partner Tenzing Norgay, to reach the top of Mount Everest . However, he also made many visits to Antarctica . In 1957, he led the first trip over ice to the South Pole. Hillary also helped his home country, New Zealand, build a research center on Antarctica, called Scott Base. He visited it in January 2007, when he was 87 years old. In the 1900s, many people like Hillary saw Antarctica as an exciting place. Scientists are interested in how glaciers flow and melt. They also worry that global warming is making glaciers melt faster. It has caused a 75 percent increase in ice loss in the last 10 years, according to a new study. Scientists say ice loss could cause water levels around the world to rise faster than expected. Ice is melting faster than expected because of global warming. Researchers in Antarctica are studying many other subjects too. Some use the cold weather and clear air as a way to study things that affect other parts of the globe. Antarctica has the cleanest air in the world. That allows scientists to compare the air there to the air in polluted places. Antarctica is the darkest place on earth, so it is a great place to study the stars. Some scientists are even studying penguin droppings . They have developed a new test to learn more about penguins' diets. Question: The final result of global warming is that _ . Yes or no, is the answer "water levels could rise faster"?
Yes

Q: Article: Winter begins in the north on December 22nd. People and animals have been doing what they always do to prepare for the colder months. Squirrels , for example, have been busy gathering nuts from trees. Well, scientists have been busy gathering information about what the squirrels do with the food they collect. They examined differences between red squirrels and gray squirrels in the American state of Indiana. The scientists wanted to know how these differences could affect the growth of black walnut trees. The black walnut is the nut of choice for both kinds of squirrels. The black walnut tree is also a central part of some hardwood forests. Rob Swihart of Purdue University did the study with Jake Goheen, a former Purdue student now at the University of New Mexico. The two researchers estimate that several times as many walnuts grow when gathered by gray squirrels as compared to red squirrels. Gray squirrels and red squirrels do not store nuts and seeds in the same way. Gray squirrels bury nuts one at a time in a number of places. But they seldom remember where they buried every nut. So some nuts remain in the ground. Conditions are right for them to develop and grow the following spring. Red squirrels, however, store large groups of nuts above ground. Professor Swihart calls " _ ". Gray squirrels are native to Indiana. But Professor Swihart says their numbers began to decrease as more forests were cut for agriculture. Red squirrels began to spread through the state during the past century. The researchers say red squirrels are native to forests that stay green all year, unlike walnut trees. They say the cleaning of forest land for agriculture has helped red squirrels invade Indiana. Jake Goheen calls them a sign of an environmental problem more than a cause. Question: The difference between gray squirrels and red squirrels mainly lies in _ . Yes or no, is the answer "the place they store the walnuts"?
A: No

Article: When most of us hear the word chocolate, the verb that comes to mind is probably "eat", not "drink", and the most proper adjective would seem to be "sweet". But for about 90 percent of chocolate's long history, it was strictly a beverage , and sugar didn't have anything to do with it. The Origin of Chocolate Many modern historians have estimated that chocolate has been around for about 2000 years, but recent research suggests that it may be even older. In the book The True History of Chocolate, authors Sophie and Michael Coe prove that the earliest linguistic evidence of chocolate consumption dates back three or even four thousand years. Valuable and Fashionable Chocolate Beverage It's hard to discover exactly when chocolate was born, but it's clear that it was cherished from the start. For several centuries in pre-modern Latin America, cacao beans were considered valuable enough to use as currency. 100 beans could purchase a good turkey hen, according to a 16th-century Aztec document. Sweetened chocolate didn't appear until Europeans discovered the Americas and sampled the native cuisine. Chocolate didn't suit the foreigners' taste at first -- one described it in his writings as "a bitter drink for pigs" -- but once mixed with honey or cane sugar, it quickly became popular throughout Spain. By the 17th century, chocolate was a fashionable drink throughout Europe, believed to have nutritious, medicinal functions. But it remained largely a privilege of the rich until the invention of the steam engine made mass production possible in the late 1700s. The Birth of Solid Chocolate In 1828, a Dutch chemist found a way to make powdered chocolate. His product became known as "Dutch cocoa", and it soon led to the creation of solid chocolate. In 1847, Joseph Fry created the first modern chocolate bar. By 1868, a little company called Cadbury was marketing boxes of chocolate candies in England. Milk chocolate hit the market a few years later. Prosperous Chocolate Industry In America, chocolate was so valued during... Question: Why did chocolate suit the Spanish's taste so quickly? _ Yes or no, is the answer "Because chocolate was sweetened with honey or cane sugar."?
