[Q]: Article: John Coltrane was born in North Carolina in 1926 and raised in the small farm town of High Point. As a young boy, he spent a great deal of time listening to the music of the black Southern church. Coltrane's father sewed clothes and could also play several musical instruments for his own enjoyment. The young Coltrane grew up in such a musical environment. And he discovered jazz by listening to the recordings of such jazz greats as Count Basie and Lester Young. When John was thirteen, he asked his mother to buy him a saxophone. People realized almost immediately that the young man could play the instrument very well. John learned by listening to the recordings of the great jazz saxophone players, Johnny Hodges and Charlie Parker. In 1943 John and his family moved to Philadelphia, Pennsylvania. He studied music for a short time at the Granoff Studios and at the Ornstein School of Music. He served for a year in a Navy band in Hawaii. When he returned, he began playing the saxophone in several small bands. In 1948, Coltrane joined trumpet player Dizzy Gillespie's band. Seven years later, Coltrane joined the jazz group of another trumpet player, Miles Davis.Then he began experimenting with new ways to write and perform jazz music, and explored many new ways of playing the saxophone.Some people did not like this new sound, while others said it was an expression of modern soul and represented an important change. By 1965, Coltrane became one of the most famous jazz musicians in the world. He was famous in Europe and Japan, as well as in the United States. He was always trying to produce a sound that no one had produced before. Some of the sounds he made were beautiful. Others were like loud screams. Miles Davis said Coltrane was the loudest, fastest saxophone player that ever rived. Many people could not understand his music. But they listened anyway. Coltrane never made his music simpler to become more popular. He continued to perform and record even as he suffered from liver cancer. He died in 1967 at the age of forty in Long Island, New York.

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

[Q]: Article: Maybe you never opened that account, but someone else did ----someone who used your name and personal information to commit fraud . When an imposter uses your name, your credit card number, or some other piece of your personal information for their own purpose -in short, when someone takes your personal information without your knowledge -it's a crime, pure and simple. The biggest problem is that you may not know your identity has been stolen until you notice that something's wrong: you may get bills for a credit card account you never opened, your credit report may include debts you never knew you had, a billing cycle may pass without your receiving a statement, or you may see charges on your bills that you didn't sign for, and even don't know anything about. If someone has stolen your identity, the Federal Trade Commission (FTC) suggests that you take three actions immediately. First, contact the fraud departments of each of the three major credit offices. Tell them to flag your file with a fraud alert including a statement that creditors should get your permission before opening any new accounts in your name. Then, ask the credit offices for copies of your credit reports. Credit offices must give you a free copy of your report if it is not correct because of fraud. Review your reports carefully to make sure no additional fraudulent accounts have been opened in your name or unauthorized changes made to your present accounts. In a few months, order new copies of your reports to check your corrections and changes, and to make sure no new fraudulent activity has occurred.
