Question: 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.

Question: Article: My son Paul got a job in a large chain of guitar stores. It was the first time for him to do such a job. The pay was based on a small salary and his sales. They offered him some training on how to get close to a customer, introduce the product and make the sale. However, he wasn't doing well. He was very _ . One morning Paul said to me, "Mum, you used to be a sales trainer. Can you tell me why I'm not doing well?" I said, "The key is that you must love the people you are selling your product to, not count the money you will make in your mind. Do what is best for them even though they are just buying something small or a cheap guitar." He promised he would try it. After some time, his sales began to increase. He became the top salesman in the store and his salary was increased. Within six months, he was one of the top ten salespeople in the whole chains of guitar stores around the country. His company held a big party to honor the top ten salespeople. New cars, great hotels and delicious dinners were the prizes. Paul was of course included. After the dinner, the boss of the company asked, "Paul, how did you make it?" Paul answered, " I don't want to tell you. You won't believe me." "Of course I'll believe you. Tell me." "I started loving the people who came in," Paul told him. The boss replied, "Okay Paul, now tell me how you REALLY make it."

Question: Article: One of the most successful singers of the twentieth century, Ella Fitzgerald has made several different styles of her own. She was born in Virginia but was brought up in an orphanage in Yonkers, New York. Chick Webb _ her in an amateur competition when she was sixteen. He engaged her to sing with his band and when he died in 1939, she took over. Unlike Bessie Smith, Ella Fitzgerald taught herself the sentimental music so popular in the 1930's -- songs like "My Heart Belongs to Daddy"-- and her recordings became best-sellers. During the 1940's she developed her own "scat singing" -- a breathless, nonsense--syllable style--for songs like "Flying Home" and "Lady Be Good." Ella Fitzgerald was the perfect musical partner for her friend, the trumpeter Louis Armstrong, matching him in warmth and artistry. "I just like music, period," she said. "To me, it's a story. There's only one thing better than singing.... It's more singing."
Question: What does the passage mainly discuss?
Options: (A) A comparison of Ella Fitzgerald and Bessie Smith. (B) The musical career of Ella Fitzgerald. (C) Ella Fitzgerald's early childhood. (D) Ella Fitzgerald's most recent recordings.
