[EX Q]: Article: The Great Barn Adventure One morning when I was 11, I explored the town's abandoned round grain barn . I found a chained sliding door that was wide enough for me to pass through. Inside, there was a heavy smell of dead mice in the dark. After my eyes adjusted, I noticed a shaft that rose all the way to the top of the barn. On one side was a one-man elevator with a long rope and roller. I stepped onto the platform and gave the rope a drag and the elevator began sliding up the shaft, but stopped halfway. After a brief panic attack, I noticed holes in the wall at regular intervals, forming a ladder. For reasons known only to an 11-year-old, I decided it would be better to go up than down. So, with shaking hands, I began climbing the wall. After what seemed like forever, I reached the top of the shaft. I stood up, dusted myself off and found absolutely nothing of interest. It was just an empty room with a ladder leading up to the roof. I climbed all the way up here for this? Then I noticed a fire extinguisher ,which I'd always wanted to shoot off. So this was the chance of a lifetime. I tried it, and, much to my surprise, the thing worked! It shot out a thick cloud of powder that instantly filled the room. I couldn't breathe. I was going to choke to death, and they'd probably never even find my body. Luckily, I remembered the ladder to the roof. I climbed up, popped the straw roof and saw a bright blue sky. I suddenly realized the dust and powder pouring out of the top could draw attention. So when the dust had settled, I climbed down and slipped out of the chained door. I'm not sure if I was more excited about being alive or about not being caught, but I ran all the way back home.

[EX 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.

[EX Q]: Article: King Juan Carlos of Spain once insisted "kings don't give up the throne , they die in their sleep." But embarrassing scandals and the popularity of the republican left in the recent Euro-elections have forced him to eat his words and stand down. So does the Spanish crisis suggest that monarchy is seeing its last days? Does that mean the writing is on the wall for all European royals, with their magnificent uniforms and majestic lifestyles? The Spanish case provides arguments both for and against monarchy. When public opinion is particularly polarized, as it was following the end of the Franco regime, monarchs can rise above mere politics and symbolize a spirit of national unity. It is this apparent transcendence of politics that explains monarchs continuing popularity as heads of state. And so, the Middle East excepted, Europe is the most monarch- filled region in the world, with 10 kingdoms (not counting Vatican City and Andorra). Most royal families have survived because they allow voters to avoid the difficult search for a non-controversial but respected public figure. Even so, kings and queens undoubtedly have a downside. Symbolic of national unity as they claim to be, their very history and sometimes the way they behave today symbolizes outdated and indefensible privileges and inequalities. At a time when Thomas Piketty and other economists are warning of rising inequality and the increasing power of inherited wealth, it is strange that wealthy noble families should still be the symbolic heart of modern democratic states. The most successful monarchies try their best to abandon or hide their old noble ways. Princes and princesses have day-jobs and ride bicycles, not horses (or helicopters). Even so, these are wealthy families who party with the international 1%, and media interference makes it increasingly difficult to maintain the right image.
Question: Monarchs are kept as heads of state in Europe mostly
Options: (A) owing to their undoubted and respectable status (B) to achieve a balance between tradition and reality (C) to give voters more public figures to look up to (D) due to their everlasting political symbolizing
