Input: Consider Input: Article: A recent study suggests that teens' relationship with parents, friends and teachers may have a lot to do with why they don't get a good night's sleep. David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens' sleep. And problems at school also affected teens' sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night's sleep. These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we're happy and contented, we're much more likely to sleep better than if we're sad and anxious. Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It's a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers. Clearly, teenagers aren't getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress.
Question: What is the passage mainly about?
Options: (A) Teens' sleep is linked to their relationship with people around them. (B) Lack of adequate sleep puts teens at risk of many bad consequences. (C) Modern technology has something to do with teens' sleep problems. (D) It is necessary for teens to join in sports and positive social activities.

Input: Consider Input: Article: "We do look very different; we're older. Leo's 38, I'm 37. We were 21 and 22 when we made that film. You know, he's fatter now -- I'm thinner.". So says Kate Winslet, who is thrilled at the 3-D re-release ofTitanicto coincide with the 100th anniversary of the ship's demise. " It happens every time I get on any boat of any kind." She recalls. There are all the people who want her to walk to the front of the ship and re-create her famous pose, arms flung wide. Most people remember the tragedy: The British passenger ship -- said to be unsinkable -- hit an iceberg and sank on April 15, 1912, during its maiden voyage from England to New York City. More than 1,500 people died. But little known is what the world learned from the sinking to prevent future incidents. Probably the greatest deficiency of the Titanic was that she was built 40 years before the widespread use of the wonderful invention radar . Her only defense against icebergs and hidden obstacles was to rely on manned lookouts. On that fateful night the eyesight of trained lookouts only provided 37 seconds of warning before the collision. Traveling at nearly 30 miles an hour the Titanic was moving far too fast to avoid the huge iceberg. The warning did prevent a head-on collision as the officer on the bridge managed to turn the ship slightly. The last ship to send a warning was the California. She was within ten miles of the Titanic during the disaster, but her radio operator went to bed at midnight and never received any of the SOS messages from the Titanic. That was one of the important lessons learned from the catastrophe, the need for 24-hour radio operators on all passenger liners. Another lesson learned was the need for more lifeboats. The Titanic remained afloat for almost three hours and most of the passengers could have been saved with enough lifeboats. 1,500 passengers and workers died in the 28 degree waters of the Atlantic. Out of the tragedy, the sinking did produce some important maritime reforms. The winter travel routes were changed to the south and the Coast Guard began to keep an eye on the location of all icebergs. The new rules for lifeboats were obvious to all. There must be enough lifeboats for everybody on board. The most important lesson learned was that no one would ever again consider a ship unsinkable- no matter how large or how well constructed. Never again would sailors place their faith in a ship above the power of the sea.
Question: The text mainly tells us _ .
Options: (A) the reason why the Titanic sank in the Atlantic Ocean (B) how the unsinkable ship of Titanic sank in the Atlantic Ocean (C) the lessons that we could learn from the accident of theTitanic (D) the things we should do to protect the lives on the ship
Asnwer: C

Output: Yes

Input: Consider Input: Article: I want to let you know about an event that changed my life many years ago. We were living in College Station, Texas and my wife and I were on our way home from Houston, Texas one Sunday morning. We decided to stop at a local gas station to get something to eat since we had enough time. When we finished, we got back into our car and before I started it, we noticed a homeless man standing in front of the building. His clothes were worn and it looked as if he didn't have any money. It was cold and I was sure he wanted something to drink. However, it was not this that moved me. A dog was also walking up to the front of the building. Being a dog lover, I noticed that the dog was a mother and that she had just had some puppies . She was hungry and weak and I felt so bad for her. I knew if she didn't eat soon, she and her puppies would not live on. People walking by didn't even notice her. She might not have been as pretty and clean as most, but she still deserved better. But we still did not do anything, someone else did. The homeless man, who I thought could not afford anything to eat, went back into a store and bought dog food with all the money he had. I know that this story isn't as inspirational as most stories, but it plays a great part in our lives. You see, that was Mother's Day weekend. And a lot of people forget that some animals are parents too.
