PROBLEM: 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.

PROBLEM: Article: A man once said how useless it was to put advertisements in the newspaper. "Last week, " he said, "my umbrella was stolen from a London church. As it was a present, I spent twice its worth in advertising, but didn't get it back. " "How did you write your advertisement? " asked one of the listeners, a merchant. "Here it is, " said the man, taking out of his pocket a slip cut from a newspaper. The other man took it and read, "Lost from the City Church last Sunday evening, a black silk umbrella. The gentleman who finds it will receive ten shillings on leaving it at No. 10 Broad Street. " "Now, " said the merchant, "I often advertise, and find that it pays me well. But the way in which an advertisement is expressed is of extreme importance. Let us try for your umbrella again, and if it fails, I'll buy you a new one.

He is well known. " This appeared in the newspaper, and on the following morning, the man was astonished when he opened the front door.
