TASK DEFINITION: In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.
PROBLEM: Article: As any parent with an iPhone or an iPod Touch knows, mobile apps can be an engaging and entertaining experience for kids. Now, a new study of PBS Kids suggests that the experience can be an educational one as well. The study, which was administered by PBS under a grant from the Department of Education, first tested the vocabulary level of a group of 90 Title 1 school children, aged 3 to 7. Then, the children were each given two weeks with an iPod Touch loaded with the Martha Speaks Dog Party app created by PBS Kids. The study monitored how the children used the iPod, during what hours, and in what context. On average, the study found that kids played with the iPod Touch for a total of 5 hours across the two weeks, with half that time spent playing the Martha Speaks app. At the end of the two week trial, the children were given another vocabulary test, which revealed an increase in vocabulary acquisition by as much as 31 per cent. The study findings are particularly useful as smart phones and mobile devices have become increasingly popular among families and parents are faced with a proliferation of mobile apps designed for kids. According to a recent Nielsen study, smart phone usage is 12% higher in households with children than other households. "Mobile apps can be a great learning tool in the hands of children," said Lesli Rotenberg, SVP, Children's Media, PBS. "This research is important in helping to better understand and guide the development of new apps that improve the value of children's screen time with significant educational outcomes." So what does it all mean? At best, it provides more evidence that mobile devices and apps do indeed have educational value and could be an important part of the child-learning process for many years to come.
Answer: It's too early for kids to use smart phones

PROBLEM: Article: This story took place a long time ago. But it has been repeated time and time again. Everyone is moved by the true story. An old man was knocked down by a car and was taken to hospital. He was badly hurt, and during his few returns to consciousness, he repeatedly called for his son. None knew where his son was. A dirty letter was found in his pockets. The nurse learned that his son was a solider inprefix = st1 /North Carolina. The hospital called the Red Cross offices to find the young man. The young solider was rushed to the airport in time to catch the plane. It was evening when the young solider walked into the hospital. A nurse took him into the bedsides of the old man. "Your son is here," she said to the man. She had to repeat the words several times before the old man's eyes opened. He dimly saw the young man and got great comfort. He reached out his hand. The young solider held the old man's hand and offered words of hope. All through the night the young solider sat besides the bed. The nurse offered to watch instead of him for a while. He refused. At dawn the old man died. The nurse started to comfort him but the solider asked her, "Who was that old man?" "He was your father," she answered. "No, he wasn't. I never saw him before." "I knew right away there was a mistake, but I also knew he needed his son, and his son just wasn't here. I realized I was needed. So I stayed."
Answer: He was seriously injured and would die soon.

SOLUTION: What is true about the old man?

PROBLEM: Article: Glaucoma is a major cause of blindness around the world, especially in developing countries. The World Health Organization says glaucoma is a greater public health challenge than cataracts , because the blindness caused by the latter can be cured after operations. Glaucoma is a disease that makes people around the world lose their sight, and they usually don't even know they have the disease until it has permanently destroyed at least 40 percent of their sight. The process is usually so painless and subtle , so people don't notice it. Actually, the simplest medical test can discover it. "It is the leading cause of blindness in the United States. In Hispanics and in African-Americans, it's the second leading cause of blindness and so is the case in the Chinese and Indians." said Dr. Alan Robin, a specialist in treating glaucoma. "The glaucoma we see in sub-Saharan Africa is a much more aggressive blinding disease than the glaucoma we see in Americans or even African- Americans in-the United States." he said. . Dr. Eric Fleischer also sees at Medstar Washington Hospital Center. "Pretty much anybody who has ancestors in Africa has an increased chance of developing glaucoma." Age is another thing that may lead to glaucoma, although people of all ages can get it. Glaucoma is a group of diseases that commonly produce pressure in the eye. An eye is sort of like a watch. And behind the face of the watch, liquid is made. It goes through your pupil and into the front of the watch between the face and the crystal.There's an area around the edge of the watch that drains the liquid. When that drain is blocked, the liquid can't leave the eye as fast as it is produced. The rising pressure within the eye damages and eventually kills the optic nerve. The result is blindness. Fortunately, if caught early, glaucoma can be controlled. Glaucoma is not curable. But as researchers worldwide lean more about it, they grow more hopeful that glaucoma can one day be cured or even prevented.
