Example input: Article: Homework can put you in a bad mood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Q: Article: If you are not any kind of a longtime A-list New Yorker celebrity like Woody Allen,chances are that you have never experienced,and will never experience-a meal in a legendary Italian-American restaurant called Rao's. Rao's,the East Harlem restaurant with a history of more than l00 years,is simply the toughest restaurant to get a reservation in the US, if not the world.Michelin three-star restaurants like elBulli in Spain,often ranked the world's top restaurant,would sell out the second phone lines opened.But in the case of Rao's,the phone lines never open. There are about a dozen tables in the tiny restaurant, and each is spoken for, semi-permanently, as regulars have had their reservations for years, and when they can't use them,they often gift them to friends. The place is so small that the owners rarely have the flexibility to do favors even for people they know. Since it is always busy,there has never been a need for publicity.The last remarkable national review of the restaurant came from The New York Times more than 35 years ago.It was already tough to get a table at Rao's but reservations have been non-existent ever sincce the magic review. According to a critic who is "very, very lucky to have dined at Rao's a few times,"the experience rivals the tasty food.There are no menus at Rao's, and one of the owners will pull up a chair and run through the massive list of options, allowing people to have diner by mixing and matching nearly any ingredient with any classical Italian style of cooking. The place doesn't take credit cards, isn't open on weekends or for 1unch, and "at some point during your meal the one-room restaurant will almost unavoidably break out in song." It is truly one of a kind,"the critic wrote.
