Example Input: Article: The 9.2magnitude earthquake which caused the tsunami in the Indian Ocean on Boxing Day last year occurred at 7:58 a.m.,95 miles off the west coast of Aceh, Indonesia. Eighteen minutes later.10-metre high waves crashed the ashore along a 500----mile-long stretch of Aceh. Two hours later the tsunami hit Thailand and Malaysia and then Burma, Bangladesh, India,the Maldives,Sri Lanka,Kenya and Somalia.The final death toll is thought to be about 280,000,with tens of thousands more listed as missing.More than l.8 million people lost their homes. *What Is Tsunami? A tsunami is a chain of fast moving waves caused by a sudden strong quake in the ocean.They can be caused by earthquakes,volcanic eruptions ,or even the collision of meteorites .Tsunamis are also incorrectly known as tidal waves,but unlike tidal waves they are not caused by changes in the tides. They are also most common around the edge of the Pacific,where more than half of the world's volcanoes are found.These fast moving waves can attack coastlines,often with little or no warning.Rocks weighing as much as 20 metric tonnes have been pulled from sea walls and carried l 80m inland. *Wave Power Atsunami can have a wavelength in excess of 1 00km and there may be an hour between them.They travel at great speeds across an ocean with hardly any energy losses and are barely noticeable out at sea. Over the deep Pacific Ocean,a tsunami travels at about 800kph.If an earthquake happened in Los Angeles.a tsunami could hit Tokyo quicker than you could fly between the cities by jet. *Strange Animal Behaviors Ten days before giant waves slammed into Sri Lanka and India coastlines,wild and domestic animals seemed to know what was about to happen and fled to safety. Elephants screamed and ran for higher ground. Dogs refused to go outdoors. Zoo animals rushed into their shelters and could not be enticed to come back out.

Example Input: 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.
Question: Which of the following cities may be the cheapest for employees overseas?
Options: (A) Geneva. (B) Sydney. (C) Tokyo. (D) New York.
Example Output: D

Example Input: Article: Soon after you have your first child, the question of having a second one is raised by friends and family. However, as the pattern of having two children in a family is challenged by modern family units, there are a few reasons why it is not selfish to want only one child. Today, the role of women has changed a lot. But nowadays, a wife has to help her husband earn the bread and butter as well as well as looking after her family. In demanding times like these, a woman has to put in more physical and emotional effort than any other member of the family. Raising a child comes at a cost that remains only heard of, until you find yourself paying it. The good reality of double income with no kids suddenly comes crashing down when there is a child involved in the picture. When one parent (the mother) needs to take some time off to look after the newborn, only one person becomes the earning member. Of course, the expenses went up rapidly. According to Susan Newman, PhD, a social psychologist, the average cost of raising a child is $227,000 from birth to college. Most young mothers also think that having one child would mean that there is more income for the child, and thus, better facilities can be provided. It is much easier to educate a single child at a good school, and give him/her better life with more resources at hand. With several children in the house, it becomes increasingly difficult to find ways to spend time with all of them. Dividing your time with just one child means that you can devote a little more time to doing the things you want to. In a single child unit, there are less comparison and more chances for positive motivation to learn new things. A happy child, who deserves the rightful attention, love, care, and time from both the parents, always gets a meaningful childhood, for both the parents and the child.
Question: What does the writer mainly want to tell us in the passage?
Options: (A) It is not selfish to have only one child in a family. (B) Raising a child costs a lot nowadays. (C) It is more difficult to raise several children in a family. (D) Women are playing a more important role in the family than before.
