PROBLEM: Article: As I was busy working on my work plan in my bedroom, I could hear my four children playing upstairs. Suddenly, I heard the children running down the stairs and shouting, "Freddie, Freddie." _ My three-year old son Freddie was lying on his side on the ground. I cried for my husband Simon to dial 999 and within minutes the air ambulance arrived. They quickly took him in the helicopter. During the flight, Freddie was looking at me and I remember thinking was a good sign, but then his eyes began to roll. As the doctors tried to stabilize him, I couldn't believe what was happening. When we arrived at the hospital in Portsmouth, there were some doctors and nurses waiting for us and they immediately set to work on Freddie. I was hopelessly wishing everything would be alright, but Freddie had broken his skull in two places and blood clots were forming in his brain. He needed surgery , and only a surgeon at another hospital in Bristol could do it. This meant another helicopter ride, but we couldn't go with Freddie because there was no enough space. Simon and I drove the long 130 miles from our home in north Devon in silence. Neither of us dared say what we were thinking, "What if we get there and he's dead?" "Is he going to be brain-damaged?" Freddie was just coming out of surgery when we arrived. The surgeon said it had gone well. When I finally saw him, I hardly recognize my child--he was covered in tubes and there were wires coming out of his head. On the third day, Simon went home to see our three girls and to pick up some clean clothes for us. While he was gone, the pressure in Freddie's brain suddenly increased. He was taken into theater again and this time I fell apart. Luckily, the surgery managed to stabilize Freddie. After almost a week, Freddie was finally woken up. When he opened his eyes, he looked at me. He didn't say anything, but I knew straight away that it was my old Freddie, and that he was going to be alright. Over the next two weeks, his recovery went well. After help with learning to swallow again and encouragement with speaking, he was soon playing with his Gruffalo cards and eating meals by himself. I still don't know how the accident happened, but we got some idea from our girls. Clearly Freddie and Minnie had been sitting on the window ledge, and Freddie must have opened it to look out and fallen 20 feet onto the ground below. The guilt I feel is awful-- for weeks I was full of " if onlys", and we put window locks everywhere. Six months later, although the accident seems a lifetime ago, it has changed me. I feel differently about life now. I've left my job to put my children first. I want to spend every minute with them.
Answer: Because no surgeons in the first hospital could do surgery on the author's son.

SOLUTION: Why did the author's son have to be moved to another hospital in Bristol?

PROBLEM: Article: Many people believe Henry Ford invented the automobile . But Henry Ford did not start to build his first car until 1896. That was eleven years after two Germans developed the world's first automobile. Many people believe Henry Ford invented the production line that moved a car's parts to the worker, instead of making the worker move to the parts. That is not true, either. Many factory owners used methods of this kind before Ford. What Henry Ford did was to use other people's ideas and make them better. And he made the whole factory a moving production line. In the early days of the automobile, almost every car maker raced his cars. It was the best way of gaining public notice. Henry Ford decided to build a racing car. Ford's most famous race was his first one. It was also the last race in which he drove the car himself. The race was in 1901, at a field near Detroit. All of the most famous cars had entered, but only two were left: the Winton and Ford's. The Winton was famous for its speed. Most people thought the race was over before it began. The Winton took an early lead. But halfway through the race, it began to lose power. Ford started to gain. And near the end of the race, he took the lead. Ford won the race and defeated the Winton. His name appeared in newspapers and he became wellknown all over the United States.Within weeks of the race, Henry Ford formed a new automobile company. In 1903, a doctor in Detroit bought the first car from the company. _ was the beginning of Henry Ford's dream. Ford said: "I will build a motor car for a great number of people. It will be large enough for the family, but small enough for one person to operate and care for. It will be built of the best materials. It will be built by the best men to be employed. And it will be built with the simplest plans that modern engineering can produce. It will be so low in price that no man making good money will be unable to own one." The Model T was a car of that kind. It only cost $850. It was a simple machine that drivers could depend on. Doctors bought the Model T. So did farmers. Even criminals. They considered it the fastest and surest form of transportation. Americans loved the Model T. They wrote stories and songs about it. Thousands of Model T's were built in the first few years.
Answer: To draw public attention.

SOLUTION: Why did Henry Ford take part in the 1901 car race?

PROBLEM: Article: A TV grab shows anchorman Bai Yansong wearing a green tie on Oct 19, 2011. "I just want the students to know that I'm also wearing a green one. And we are all great people and are as good as those wearing red scarves." Bai Yansong, a famous anchor of China Central Television, voiced his support to students wearing green scarves at a primary school in Xi'an by wearing a green tie on a TV program, Oct 19, 2011. The program focused on a recent controversial issue, triggered by First Experimental Primary School in Northwestern China's Xi'an that made children whose schoolwork and general behavior were not yet good enough to wear green scarves instead of the red scarf of the Chinese Young Pioneers. "The original idea for designing the green scarf was to strengthen education and to encourage the pupils to work harder," said Chen Hong, the school's principal. The practice that divided students into "good" and "bad" has aroused a lot of discussions on Sina Weibo, a Chinese twitter-like microblogging website. The color1 of green in Chinese culture carries an annoying implication particularly because "green hats" are the Chinese symbol of a cuckold. Many Weibo users thought it was inappropriate to make pupils wear green scarves. "It is a violation of dignity to make bad students wear green scarves," said a blogger with the username Suosez. "If bad students have to wear green scarves, then bad teachers should wear green hats," another blogger said. "The Chinese version of Steve Jobs has died in primary school because his pride has been hurt by the green scarf," said another blogger. "It is an discrimination against children," said yet another. "Seeing the students in Xi'an wearing green scarves reminds me of some miserable memories. I cannot forget that I was the second group to wear a red scarf in my class. I cannot forget the scar on my hand left by my Chinese teacher. And I cannot forget that my math teacher threw my test paper on the ground and insisted that it was copied," a blogger with the username Kivalailai recalled. "The green scarves will cast a shadow over the students and bring them inferiority or jealousy, which are quite bad for their mental health," said a blogger. The school has halted the use of green scarves as on Wednesday, parent-teacher meetings were held to explain the situation, according to teachers at the school.
