user: Problem: Given the question: Write a multi-choice question for the following article: Article: On Friday, Japanese researchers announced a population clock that showed a dangerous situation that the Japanese nation would disappear in 1,000 years if the falling birth rate kept the present level. Researchers in the northern city of Sendai said that Japan's population of children aged up to 14, which now stands at 16.6 million, was falling at the rate of one child per 100 seconds. It would lead to a terrible result that there would be no children left in Japan in 1,000 years. "If the rate keeps falling at that rate in our country, there will only be one child who is able to enjoy the following Children's Day left on May 5th, 3011," said Hiroshi Yoshida, a professor at Toholu University. "But 100 seconds later, a national disaster that there are no children left in Japan will happen," he added, "The nation's people will disappear for the birth rate has fallen to the level that every woman has no more than two children, which started in 1975." Yoshida said they created the population clock to make Japanese people pay close attention to that problem for their nation's future. Another study showed that Japan's population was expected to fall to one third of the present population amount: 127.7 million in the next century. The Japanese government predicted that the birth rate would just become 1.35 children per parents within 50 years. At the same time, Japanese life expectancy which is expected to ascend from 86.93 years in 2010 to 90.93 years in 2060 for women and from 79.64 years to 84.19 years for men has already been one of the highest in the world. More than 20 percent of the Japanese are aged 65 or over. It means that Japan has become one of the countries with aging populations in the world. The problem of aging populations is a headache for the government and the Japanese economy because there are fewer and fewer workers who can make money for the country. However, the government has to face the terrible situation that it needs to offer a growing number of pensions.

input question: Write a multi-choice question for the following article: Article: Neddine Parker is up by 7 in the morning. After her morning exercises and some housework, she drives to the local hospital, where she volunteers once a week. What makes Parker's routine so extraordinary is that she is 104 years old. "I don't know why I'm still here," she said. Dr. Thomas Perls of the Boston University Medical Center is trying to figure that out. As the director of the New England Centenarian   Study, he studies there "super humans", those age 100 years and older. "It's like winning the lottery", he said. "You've got to choose the right numbers and the right combination." Researchers believe about 30 percent of aging is genetic. For those who get to extremely old ages, family history may play an even more important role. Reuben Landau's mother lived to 100, and three of his brothers and sisters into their 90s. Landau is nearly 102, and he still practices law a few hours every day. Both Landau and Parker are remarkably healthy. They take few medications and have no major illness. Perls has found that many centenarians lack a type of gene -- E4 -- that is associated with an increased risk of heart disease. One study found the gene is in 29 percent of young men, but only 15 percent of centenarians. Perls also believes they may have a "protective gene", one that helps them survive what might kill others. Parker, for example, smoked until she was 100 and had a stroke at 89. However, living into your 100s isn't just genetics. Aging successfully has much to do with environment and behavior. Landau watches what he eats and exercises his body and mind every day. He's convinced it's why he's still in good health. "People still have to do the right things to get to very old age," said Perls. So it's not just the cards you're dealt, but how you play the hand.???
output answer: Question: Why are Landau and Parker remarkably healthy according to the research?Options:A Because they are remarkably active in mind.B Because they lack a gene linked to illness.C Because they are fond of social work.D Because they enjoy sports and housework.Answer:B

Write a multi-choice question for the following article: Article: How to Become Cleverer? Once a boy came to ask a fisherman how to become cleverer, because his mother always called him "foolish boy". "That's easy," answered the fisherman. "I know one way to make you become cleverer." "Really?" "Of course. It is said a fish head is good for brain. If you eat one, you'll become cleverer indeed. Pay only three pounds for one fish head." The boy paid him three pounds and the fisherman cut off a fish head and handed it to him. A raw fish head is not good--not even for a hungry boy to eat but the boy ate it up in two gulps. "Do you feel anything?" asked the fisherman. "Not in my head," said the boy. The boy lay on the ground and thought. "One whole fish costs only two pounds. I had paid him three pounds for the fish head. Why couldn't I have the whole fish for soup, a head for brain and one pound left over?" He jumped up and shouted at the fisherman. "You thief! You are fooling me!" The fisherman laughed, saying, "The fish head works now, you see. "

Please answer this: Write a multi-choice question for the following article: Article: After 21 years of marriage, my wife wanted me to take another woman out to dinner and a movie. The other woman my wife wanted me to visit was my mother, who has been a widow  for 19 years, but the demands of my work and my three children had made it impossible to visit her often. That Friday after work, when I arrived at her house, my mother waited in the door with her coat on. She had curled her hair and was wearing the dress that she had worn to celebrate her last wedding anniversary.  We went to a restaurant that, although not elegant, was very nice and comfortable. My mother took my arm as if she were the First Lady. During the dinner, we had an agreeable conversation, nothing extraordinary but catching up on recent events of each other's life. We talked so much that we missed the movie. As we arrived at her house later, she said, "I'll go out with you again, but only if you let me invite you." I agreed. A few days later, my mother died of a massive heart attack. It happened so suddenly that I didn't have a chance to do anything for her. Some time later, I received an envelope with a copy of a restaurant receipt from the same place Mother and I had dined. An attached note said "I paid this bill in advance. I wasn't sure that I could be there; but, nevertheless, I paid for two plates--one for you and the other for your wife. You w ill never know what that night meant for me. I love you, son." At that moment, I understood the importance of saying in time 'I love YOU' and to give our loved ones the time that they deserve. Nothing in life is more important than your family. Give them the time they deserve because these things cannot be put off till some "other" time.
