Article: Dear Editor, Recent reports have indicated an additional 1, 400 Marines are being sent to Afghanistan in the coming weeks. This means it costs over $1 million annually on the ground over there. I do place a higher level of blame on the policymakers who send soldiers off to kill and be killed in the field. I think the human race needs to think more about killing. One needs to do the _ : "Are these wars JUST?" I believe that all of our wars since 1945 have been illegal, under international law as well. I suggest that all your readers examine their conscience as it relates to the matter of making war. The fact that many soldiers are motivated by a strong sense of duty does not give them some unqualified moral right to support these wars or any other. It's responsible for all the troops, and the entire population, to determine whether the Afghan or Iraq wars are in accordance with the development of the state. I wish someone would give me one or more logical reasons why we are still fighting in Afghanistan and what our goals are. I certainly don't understand it and neither do many who are more knowledgeable than I. Outsiders have tried unsuccessfully for centuries to conquer Afghanistan, and we seem to be no more successful. We are trying to develop a stable central government, but the country is badly divided into ethnic and tribal groups, and the current government is corrupt . Moreover, we are apparently regarded as undesirable occupiers by many of its people, most notably the Taliban. If we are to continue spending billions every year in Afghanistan and killing hundreds of our people and many of theirs, our government must provide us with a reasonable explanation of why we are doing so and what we can expect to accomplish.

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.

Article: A major earthquake rocked Haiti at 4:53 pm local time on Jan.12, 2010, killing possibly thousands of people but no official figure has been released so far. The quake, which struck about 15km (10 miles) south-west of the capital, Port-au-Prince, was quickly followed by two strong aftershocks. In the space of a minute, numerous buildings fell down. A five-story U.N. building was also brought down by the 7.3 magnitude quake, the most powerful to hit Haiti in more than 200 years according to the U.S. Geological Survey. As night fell, the whole city is in total darkness. You can see thousands of people sitting in the streets with nowhere to go. There are people running, crying, screaming. Describing the earthquake as a "catastrophe", Haiti's president said the cost of the damage could run into billions. Haiti became the first independent Caribbean state in the early 19th century. Haiti's location, history and attracting climate once made it a tourist hot place. However, decades of poverty, environmental pollution and violence have left it as the poorest nation in the Americas. It has suffered a lot, including four hurricanes and storms in 2008 that killed hundreds.
Question: The great earthquake happened to the _ of the capital city.
Options: (A) south-west (B) north-west (C) south-east (D) north-east
