In this task, you're given an article, a question which often contains a blank and four options (associated with "A", "B", "C", "D"). Your task is to find the correct answer (from the given options) for the question from the given article and return one of the options from "A", "B", "C", and "D". Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.

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.

Article: Have you ever been talking to somebody at the party? Do you focus entirely on the person you are speaking with or does your attention keep jumping around the room to all the other people there? Generally speaking, if the person is someone you really want to talk to you will focus on them. Most other people will only get about half of your attention. You may think that this is OK, because if you don't really want to talk to them then what does it matter if you don't give them your full attention? Consider two things. First, you may just not realize the importance of that conversation. If you are at a networking meeting and you hope to meet the CEO of Company X but you end up talking to someone who has a low-level job at a different company, then you may let your attention wander as you speak to him. But maybe you don't realize that this person has already met the CEO and could introduce you. Do you think he will do that if he feels you don't really care about speaking to him? This doesn't mean you need to spend the entire time talking to him. Five or ten minutes of real attentive conversation can be worth 30 minutes to an hour of partial attention interaction. Second, whether you want to speak to someone changes based on the situation. You love your spouse , but if he or she tries to talk to you while you are watching something you like on TV, where is your attention going? Make your own decision, but if you want them to feel valued, give them your 100% attention. "The nice thing is that in many cases you can give them your attention for a few minutes and then return to what you were doing. You miss very little, they feel valued, and all is good." 
 Question: Generally speaking you would like to focus on someone  _  . 
 Options: (A) who is friendly to you (B) who is active at the party (C) who you want to talk to (D) who you are speaking with

Article: People have always wanted to speak with animals. There are many books about this, especially children books. Now there are also movies, such as Dr. Doolittle. When you watch animals, it seems clear that they can communicate with each other. Many people wonder why people can't also communicate with them.    Scientists know how some animals communicate. Bees, for example, use their bodies. They do a kind of dance to give information about food. Birds, on the other hand, share information with sounds. They use certain sounds to protect their homes and to stay together when they fly. Some male birds use lovely songs to attract a female . Other animals communicate with both body movements and sounds. For example, dogs wag their tails when they are happy, and they bark when they are excited.    People used to think it was possible to teach human language to animals. Parrots and other birds, for example, can learn to say words. But the birds just repeat the words. They don't understand them. Some American scientists tried to teach English to chimpanzees , close  s of human beings. However, this was impossible. Chimpanzees can't move their mouths the right way. They could never learn to speak like people.    Then scientists tried to teach human language to chimpanzees in other ways. Some tried with American Sign Language (ASL). Others tried with a simple computer. But chimpanzees could only learn to use a few words. They could never learn to use grammar. Their brains are very different from the brains of human beings.    Now some scientists are studying the same points between human and animal language. In fact, some animals use sounds like people do. Dogs, for example, use an unpleasant, low sound to tell other dogs to stay away. People, too, use that kind of voice to say the same things. A dog's noisy bark communicate that something is happening. People use the same high tone when they shout, "Watch out!"    Scientists want to understand the language of other animals, such as whales and bears. To do this, they go out to the animals' natural homes. They watch the animals for days or even years. They take pictures and make tape recordings and share the information with other scientists. In this way, they hope to learn more about the way animals communicate, and maybe someday we'll be able to communicate better with them.
