PROBLEM: Article: Philip Pullman spent a great deal of his childhood traveling abroad because both his father and stepfather were pilots in the Royal Air Force . As a child, he went on several long ocean voyages, and he lived in Africa and in Australia. "Before I was 11 I had been to eight different schools." "In Australia, I made a great discovery. TV hadn't reached Australia yet, but everyone listened to the radio. I remember listening to gangster serials , and cowboy serials, and best of all--Superman! When I first saw a superman comic , it changed my life. I'd been reading books for a long time, but I'd never known comics before. Soon afterwards, I discovered Batman, too, whom I loved even more." Pullman started writing his first novel the day after he had finished his final exams at Oxford University. "I discovered after about an hour that it was much harder than I'd expected. It still is! I found that the amount I could write comfortably every day was about three pages, so that's what I've done ever since." Before he became a full-time writer, Pullman had been teaching for many years. "What I enjoyed most during that time was telling stories over and over, until I knew them as well as I knew my own life." He had always loved telling stories--as a schoolboy he had entertained his friends by reading stories to them, or by making up his own. One day he got a letter that had arrived at his door even though the writer of the letter didn't know his address. The envelope just said, "Philip Pullman, The Storyteller, Oxford."
Answer: He traveled a lot when he was a young child.

PROBLEM: Article: Buster Brown was a thief and a good one too,he thought. He'd never been caught by the police because he never took chances.He was always prepared for any unforeseen event or emergency. Confidently,he stood outside the house of his intended victim and read the sign on the front gate of the house."Don't worry about the dog--be aware of the owner!" it said.Buster smiled and found his way in. The house looked quite normal outside,but inside it was very exotic with fascinating objects on display.As he began putting them into his bag,a dog came into the room.It stopped when it saw Buster,then wagged its tail madly and went over to him,licking his outstretched hand. "Good boy," Buster whispered. "What a great guard dog you are--trying to lick me to death." Satisfied he'd made friends with the dog,Bluster began to wander round the house,choosing items to put in his bag.His skilled eye picked out only the best antiques :a pair of silver candleholders,a silver tea-and-coffee service,etc..His new friend,the dog,sat and watched,as if wondering what was happening. "Well,boy," Buster whispered,finally."That might do.Any more and I won't be able to carry it!" He swung the heavy bag onto his shoulders, just as the lights came on, nearly blinding him. He shielded his eyes with his hand. "You're a very silly person," the figure in the doorway said, his voice dry and dust. As the man came closer, Buster could see he was well dressed. His face seemed familiar, but Buster couldn't quite place where he had seen him before. "You should have taken more notice of the sign outside," the man rasped. "I knew about this attempted robbery last week and I also know you will end up behind bars for 20 years. Fancy trying to rob the house of the world's greatest fortune-teller!"
Answer: He had never been caught by the police.

SOLUTION: Why was Buster so confident?

PROBLEM: Article: Most Americans receive at least two or three credit card applications in the mail every month.Why have credit cards become so popular? For a merchant, the answer is obvious.By putting charge slips in a bank, the merchant can change credit card sales into cash.In return for processing the merchant's credit card transactions , the bank charges a fee that ranges between 1.5 and 5 percent. The easiest way to establish credit is to open checking and savings accounts at your local bank.Then apply for a gasoline or store credit card.These cards are fairly easy to get because retailers want you to buy their goods and services.The third step, and the most dangerous one, is obtaining a major credit card like Visa, MasterCard, or American Express. It is important to choose a credit card carefully because terms and conditions vary widely.Annual fees range from $15 to $75 a year, but some credit card companies charge no annual fee at all.If you will be one of the growing number of people who don't pay off their credit card debts in full each month, look for the card with the lowest interest rate.Interest rates generally range from 12 to 18 percent, though it is possible to find cards with lower rates. A credit card can be your friend because it can get you through unexpected emergencies.And if there is a problem with the products or service you purchase with your credit card, you have an opportunity to hold back payment by asking the credit card company to "charge back" to the retailer until the argument is settled.Monthly credit card statements can also help you keep your records in order.Finally, if you make payments on time, the card helps you to establish a good credit history. A credit card can be your enemy because it is an invitation to purchase items you really do not need.The credit card companies' continuous offers of minimum payments, cash advances, and even months without payments may seem like a way to skate through a money crisis.In reality, your finance charges and fees only increase, and you go deeper into debt. If you do find yourself in trouble, do not ignore the bills.Contact your creditors to explain your problem and express your desire to pay down your card balance.If that fails, a nonprofit organization like Consumer Credit Counseling Service can assist you in getting back on your financial feet.
Answer: By mailing the customer's credit card to the bank.
