[EX Q]: Article: What's the most expensive place to station an employee overseas? London? Tokyo? Sao Paulo? Try Luanda, Angola. That's the finding of a survey by Mercer, the world's largest human resources consulting firm, headquartered in New York City. Two African cities (Luanda, N'Djamena) were in the top 10, along with four (Moscow, Geneva, Zurich, Bern) in Europe, three (Tokyo, Singapore, Hong Kong) in Asia and one (Sydney) in Australia. Switzerland alone has three cities in the top 10. Mercer's 2013 Cost of Living Survey examined data from 214 cities worldwide, comparing a market basket of over 200 goods and services, including unfurnished luxury two-bedroom apartments or three-bedroom houses, movie tickets, blue jeans, international newspapers, coffee, fast food restaurant meals, gasoline, milk and soda. If it sounds odd that Angola would be the most expensive, Mercer's Barb Marder explains that"Despite being one of Africa's major oil producers, Angola is a ly poor country yet expensive for expatriates since imported goods can be dear. In addition, finding secure living accommodations that meet the standards of expatriates can be challenging and quite costly."The survey found similar supply issues in N'Djamena, Chad, the other top 10 city in Africa. Mercer measured locations worldwide against New York, on a U.S. dollar basis, meaning that exchange rate shifts could impact the rankings. For example, although Tokyo is Asia's most expensive city for people who live in a foreign country, the weakening of the Japanese yen against the dollar makes it seem cheaper than it was a year ago. Canada, too, has become a bargain as the U.S. dollar strengthens against the Canadian dollar. Measurements were taken in March, 2013. What's the trend in the United States?"Overall, U.S. cities either remain stable in the ranking or have slightly decreased due to the movement of the U.S. dollar against the majority of currencies worldwide,"explains Mercer's Steven Nurney. However, that may change as real estate prices rise nationwide. New York is the nation's most expensive place to station expatriates. While housing is generally the most important factor in the survey rankings, the survey revealed some other significant differences in prices. For example, you may need a vodka chaser after paying $ 8.29 for a cup of coffee in Moscow, but the same coffee in Managua, Nicaragua would cost only $ 1.54. Expect to pay $ 20.10 for a movie ticket in London, versus $ 5.91 in Johannesburg.
Answer: New York.
[EX A]: Which of the following cities may be the cheapest for employees overseas?

[EX Q]: Article: The Boy Made It! One Sunday, Nicholas, a teenager, went skiing at Sugarloaf Mountain in Maine. In the early afternoon, when he was planning to go home, a fierce snowstorm swept into the area. Unable to see far, he accidentally turned off the path. Before he knew it, Nicholas was lost, all alone! He didn't have food, water, a phone, or other supplies. He was getting colder by the minute. Nicholas had no idea where he was. He tried not to panic. He thought about all the survival shows he had watched on TV. It was time to put the tips he had learned to use. He decided to stop skiing. There was a better chance of someone finding him if he stayed put. The first thing he did was to find shelter form the freezing wind and snow. If he didn't, his body temperature would get very low, which could quickly kill him. Using his skis, Nicholas built a snow cave. He gathered a huge mass of snow and dug out a hole in the middle. Then he piled branches on top of himself, like a blanket, to stay as warm as he could. By that evening, Nicholas was really hungry. He ate snow and drank water from a nearby stream so that his body wouldn't lose too much water. Not knowing how much longer he could last, Nicholas did the only thing he could- he huddled in his cave and slept. The next day, Nicholas went out to look for help, but he couldn't find anyone. He followed his tracks and returned to the snow cave, because without shelter, he could die that night. On Tuesday, Nicholas went out to find help. He had walked for about a mile when a volunteer searcher found him. After two days stuck in the snow, Nicholas was saved. Nicholas might not have survived this snowstorm had it not been for TV. He had often watched Grylls' survival show. Man vs. Wild. That's where he learned the tips that saved his life, In each episode of Man vs. Wild, Grylls is abandoned in a wild area and has to find his way out. When Grylls heard about Nicholas' amazing deeds, he was super impressed that Nicholas had made it since he knew better than anyone how hard Nicholas had to work to stay alive.
Answer: He got lost.
[EX A]: What happened to Nicholas one Sunday afternoon?

[EX Q]: Article: Despite organized anti-bottled-water campaigns across the country and a noisy debate about bottled water's environmental effect, Americans are buying more bottled water than ever. --------------------------------------------------------------------------------------------------- Why do so many people seem to think they should have any input on what other Americans choose to buy or do? If they want to buy bottled water, let them. If they want to eat fast food, let them. If they want to smoke pot, let them. ----Barackalypse People just get tired of paying for others' bad behavior. If many people eat too much fast food, you pay higher insurance bill. If many people frequently buy bottled water, your trash bills go up and landfills fill up quickly. It's about personal responsibility, which really should be a basis of our society. ----Bdbr So? This is the price you pay to live in a free society. You want to control the life of another just so you can save a little money? What would you say when someone do the same to you? ----Norman619 I'm just glad there are still people who still believe personal responsibility is a good thing. We make your life cheaper and less bothersome. ----Yoyo What a waste of money. It's fine when you're on the road and you need a cold drink, but people who buy cases of bottled water for home are completely crazy. ----Agmlauncher I wish we all can find a way to improve things and benefit from this. The environment needs a lot of help but businesses will always work on what people would need and demand. Is this part of the trade-off? Hope we can find better ways. ----Skipweis
