Example Input: Article: Who doesn't love sitting beside a cosy fire on a cold winter's night ? Who doesn't love to watch flames curling up a chimney? Fire is one of man's greatest friends, but also one of his greatest enemies. Many big fires are caused by carelessness. A lighted cigarette thrown out of a car or train window or a broken bottle lying on dry grass can start a fire. Sometimes, though, a fire can start on its own. Wet hay can begin burning by itself. This is how it happens: the hay starts to rot and begins to give off heat which is trapped inside it. Finally, it bursts into flames. That's why farmers cut and store their hay when it's dry. Fires have destroyed whole cities. In the 17th century, a small fire which began in a baker's shop burnt down nearly every building in London. Moscow was set on fire during the war against Napoleon. This fire continued burning for seven days. And, of course, in 64 A.D. a fire burnt Rome. Even today, in spite of modern fire-fighting methods, fire causes millions of pounds' worthy of damage each year both in our cities and in the countryside. It has been wisely said that fire is a good servant but a bad master .
Question: The writer considers it _ to sit beside a fire on a cold winter night .
Options: (A) nice (B) dangerous (C) unhappy (D) painful
Example Output: A

Example Input: Article: Dan Bebber is a senior research fellow at the University of Exeter in Britain. He says research has shown that wild plants and animals are moving toward Earth's North and South poles as the planet warms. Mr Bebber wanted to know if the same thing was happening with organisms that attack agricultural crops. He examined reports of first sightings of new insects and diseases around the world. The records came from CABI - the Centre for Agricultural Bioscience International. He says the group began collecting information from developing and industrialized countries years ago. Dan Bebber and his research team studied 612 different organisms - from viruses and bacteria to insects like beetles and butterflies. They found that since 1960, crop pests and diseases have been moving toward the poles at an average rate of about 3 kilometers each year. Mr Bebber says this puts the most productive farmland in the world in danger. "As new species of pests and diseases evolve and potentially the environment for them becomes more _ at higher latitudes, the pressure on the breadbaskets of the world is going to increase." Farmers face other threats. Invasive species passed through trade are also causing problems. Gene Kritsky is an Entomologist at the College of Mount St. Joseph in Ohio. He specialises in the study of insects. He says climate change may improve conditions for some invasive species. "It means that species in other parts of the world that might do well in warmer temperatures can now do well in the breadbasket of America." Another Entomologist Christian Krupke of Purdue University says the effects of these changes will depend very much on the crop, the insect and the disease. But he says the research is a warning sign that people should care about climate change and do something about it.
Question: The purpose of Dan Bebber's research was to find _ .
Options: (A) if farmland could be moved to colder places thanks to global warming (B) if diseases and insects harmful to crops were going towards colder areas (C) if organisms were moving to the north and south poles (D) if the number of crop pests was increasing
Example Output: B

Example Input: Article: China Daily: As China comes down from a travel rush during the seven-day holiday for National Day, people called for a return of the Labor Day Golden Week holiday as a way to ease the travel peak. By Friday, 79 million passengers were expected to have used the railways up about 8 percent over last year. Waterways had shipped around 2 million, a rise of about 17 percent on last year, www. cntv. cn, the website of China Central Television, said on Saturday. As large numbers of tourists _ scenic spots around China, it caused huge crowds and many complaints. The Forbidden City in Beijing has long been a big draw for travelers. On Tuesday alone, the museum reported, it received more than 180,000 visitors, about six times higher than a regular day. According to China Central Television, restless visitors demanded their money back from the tourism committee, and police were sent to help deal with the problem. The Beijing-HongKong-Macao expressway, the Shanghai-Kunming expressway and the route from Beijing to Kunming saw large increases in traffic on Saturday, according to www. cntv. cn. "As there are only two long holidays in the country and paid leave is not well carried out by employers , people have limited chances for travel", Dai Bin, the director of China Tourism Academy, said in a report by Beijing Times on Saturday. "The travel rush during the 'Golden Week' holidays happens because people do not take long journeys during shorter holidays", said Liu Simin, a researcher with the China Academy of Social Sciences, in a report by Beijing Times on Saturday. Liu said that now the most important task is to ease the pressure from the huge numbers of tourists. When the Labor Day Golden Week holiday came to an end in 2007, a chance to travel was reduced. In 2008, the government shortened the Labor Day Golden Week holiday, usually lasting from May 1 to May 7, to three days and added three other short vacations to the list.
Question: The Labor Day Golden Week holiday was shortened to _ .
Options: (A) one day (B) two days (C) three days (D) four days
Example Output:
C
