*Question*
"Mister D'Arcy is not a policeman. He is, however, very wise. He knew the police would search his apartment. He also knew how police think. So, he did not hide the letter where he knew they would look for it. "Do you remember how Germont laughed when I said the mystery was difficult for him to solve because it was so simple?" Dupin filled his pipe with tobacco and lit it. "Well, the more I thought about it, the more I realized the police could not find the letter because D'Arcy had not hidden it at all. "So I went to visit D'Arcy in his apartment. I took a pair of dark green eyeglasses with me. I explained to him that I was having trouble with my eyes and needed to wear the dark glasses at all times. He believed me. The glasses permitted me to look around the apartment while I seemed only to be talking to him. "I paid special attention to a large desk where there were a lot of papers and books. However, I saw nothing suspicious there. After a few minutes, however, I noticed a small shelf over the fireplace. A few postcards and a letter were lying on the shelf. The letter looked very old and dirty. "As soon as I saw this letter, I decided it must be the one I was looking for. It must be, even though it was completely different from the one Germont had described. "This letter had a large green stamp on it. The address was written in small letters in blue ink. I memorized every detail of the letter while I talked to D'Arcy. Then when he was not looking, I dropped one of my gloves on the floor under my chair. "The next morning, I stopped at his apartment to look for my glove. While we were talking, we heard people shouting in the street. D'Arcy went to the window and looked out. Quickly, I stepped to the shelf and put the letter in my pocket. Then I replaced it with a letter that looked exactly like it, which I had made it the night before. "The trouble in the street was caused by a man who had almost been run over by a horse and carriage. He was not hurt. And soon the crowd of people went away. When it was over,... Which of he following about Dupin's dropping one of his gloves is NOT true? A) He dropped it intentionally. B) He dropped it carelessly. C) He dropped it in order to drop in on D'Arcy again. D) He dropped it to make an excuse.

Millions of Americans return from long-distance trips by air, but their luggage doesn't always come home with them. Airline identification tags  can come loose, and the bags go who-knows-where. And passengers leave all kinds of things on planes. The airlines collect the items and, for 90 days, attempt to find their owners. They don't keep them, since they're not in the warehouse business. And by law, they cannot sell the bags, because the airlines might be tempted to deliberately misplace luggage. So once insurance companies have paid for lost bags and their contents, and they no longer belong to passengers, a unique store in the little town of Scottsboro, Alabama, buys them. The "Unclaimed Baggage Center," is so popular that the building, which is set up like a department store, is the number-one tourist attraction in all of Alabama. More than one million visitors stop in each year and take one of the store's shopping carts on a hunt for treasures. Each day, clerks bring out 7,000 new items, and veteran shoppers rush to paw over them. You can find everything from precious jewels to hockey sticks, best-selling novels, leather jackets, tape recorders, surfboards, even half -used tubes of toothpaste. The store's own laundry washes or cleans all the clothes found in luggage, then sells them. The Unclaimed Baggage Center has found guns, illegal drugs and even a live rattlesnake. The store has a little museum where some of its most unusual acquisitions  have been preserved. They include highland bagpipes, a burial mask from an Egyptian pharaoh's tomb, and a medieval suit of armor. Statistics indicate that less than one-half of one percent of luggage checked on U.S. carriers is permanently lost and available to the store. The reason why the airlines cannot sell the bags is that   _  . A) they have to find the owners B) they have to keep the bags as long as possible C) some bags are expensive D) they are likely to make a profit on the bags on purpose

I first went to Harrow in the summer term. The school had the biggest swimming pool I had ever seen. It was a good joke to come up behind a naked boy, and push him into the pool. I made quite a habit of this with boys of my own size or less. One day I saw a boy wrapped in a towel on the side of the pool. He was no bigger than I was, so I thought him _ . Coming secretly behind, I pushed him in, holding on to his towel so that it would not get wet, I was surprised to see an angry face come out from the water, and a being of great strength masking its way by face strokes  to the shore. I fled, but in vain. He overtook me, seized me violently, and threw me into the deepest part of the pool. I soon climbed out on the other side, and found myself surrounded by a crowd of younger boys." Do you know what you have done?" they said, "It's Amery; he is in Grade Six. He is champion at gym; he has got his football honor." I was frightened and felt ashamed. How could I tell his position when be was wrapped in a bath towel and so small."
