Example Input: Article: April sales figures show a disappointing month for Wal-Mart. The world's largest retailer reported a big drop in sales last month--its worst decline in nearly 30 years. As VOA's Mil Arcega reports, Wal-Mart is not alone. A three and a half percent drop in sales does not seem like much. But for a company that sells more than $300 billion worth of goods every year, analysts say it is significant. Alan Murray, the managing editor of the Wall Street Journal, says the drop represents Wal-Mart's biggest decline since 1979. "There are a number of things going on. Part of it is early Easter, so some of those sales got moved into March. Part of it is bad weather." But it may also signal a trend. Across the board, retailers from Target to JC Penny and the Gap, reported weaker sales in April. Analysts say the decline suggests high gasoline prices and the slowing prefix = st1 /U.S.housing market are finally catching up with consumers.Murraysays there may be other factors at play. "Wal-Mart is not doing what it used to do very well. It made an attempt last year to sell clothes to high scale retailers. That didn't work. It had to back off. It's remodeling its stores. That's not working very well," says Murray. To bring customers back, some say Wal-Mart needs to go back to its marketing basics. Retail analyst Dana Telsey says that means low priced goods in a friendly retail environment. "I think Wal-Mart is working to enhance its image. It could always be better. Going back to its roots is a way, that hopefully, customers will become familiar with it again." Wal-Mart is one of the biggest economic indicators in the retail industry. As the world's largest profit making enterprise, Wal-Mart's yearly revenues represents about 2.5 percent of total economic activity in the U.S.
Answer: The Wal - Mart's biggest drop in sales.

Example Input: Article: Many years ago in a small German town, a Jewish businessman had the misfortune of owing a large sum of money to the moneylender. The moneylender, who was old and ugly, fancied the businessman's beautiful daughter. So he proposed a bargain. The moneylender told them that he would put a black pebble and a white pebble into an empty bag. The girl would then have to pick one pebble from the bag. If she picked the black pebble, she would become the moneylender's wife and he would _ her father's debt. If she picked the white pebble, she need not marry him and her father's debt would still be forgiven. But if she refused to pick a pebble, her father would be thrown into jail. They were standing on a pebble-strewn path. As they talked, the moneylender bent over to pick up two pebbles. The sharp-eyed girl noticed that he had picked up two black pebbles and put them into the bag. He then asked the girl to pick a pebble from the bag. No doubt she was caught in a dilemma. What would you have done if you were the girl? Careful analysis would produce three possibilities: 1.The girl should refuse to take a pebble. 2.The girl should know that there were two black pebbles in the bag and expose the money-lender as a cheat. 3.The girl should pick a black pebble and sacrifice herself in order to save her father from his debt and imprisonment. The above story is used with the hope that it will make us appreciate the difference between lateral and logical thinking. Read on... The girl put her hand into the moneybag and drew out a pebble. Without looking at it, she fumbled and let it fall onto the pebble-strewn path where it immediately became lost among all the other pebbles. "Oh, how clumsy of me!" she said. "But never mind, if you look into the bag for the one that is left, you will be able to tell which pebble I picked." Since the remaining pebble is black, it must be assumed that she had picked the white one. And since the moneylender dared not admit his dishonesty, the girl changed what seemed an impossible situation into an extremely advantageous one.
Answer: The girl picked a black pebble and accepted the result.
Example Output: Which of the following indicates lateral thinking?

Example Input: Article: "Angie, I know you like to sing," her father, a worker, told Angela Brown, "but you must have something to fall back on ." Brown took her father's advice. She got a degree in secretarial science before entering Oakwood College, in Huntsville, Alabama. However, her aim was to become a singer at religious meetings. So after graduation she headed for Indiana University to study with the famous soprano Virginia Zeani. Once, when Brown was troubled by self-doubt, Zeani said to her, "If you want to be the next Aretha Franklin, you need no more lessons," Brown remembers her saying. "But if you want to be the best Verdian soprano this world has ever seen, you must work." Work she did. Three times she competed in the Metropolitan Opera National Council Auditions . Three times she failed to make the final round in New York. Then, in 1997 at age 33, the age limit for sopranos to audition, she gave it one more try. She signed up at the last minute and didn't even practice, thinking, "All they could do was to tell me no, and that didn't hurt my feelings anymore." She had the strength she needed to fall back on if she failed. She won. But making it in New York was just the beginning. It took her three more years to become an understudy at the Met. But waiting in the wings was fine with her. Finally, her time came. When the featured singer fell ill, Brown earned the chance to sing the lead role in Aida. And The New York Times described her performance as a great success. Angela Brown, who had prepared for 20 years, was an "overnight" successful singer at age 40.
Answer: From 2000 to 2004.
Example Output:
When did Angela Brown act as an understudy at the Met?
