In this task, you're given an article and an answer. Your task is to generate the fill-in-the-blank question for this answer based on the given article. The blanks are always at the end of the question, and can be filled with more than one word or phrase.
Example: Article: Homework can put you in a badmood , 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.

Problem: Article: Most people can only dream of living for 100 years, let alone fathering a child nearly a century after being born themselves. But that is apparently a reality today, as a 96-year-old Indian man claims to have fathered a child, his second in recent years. Ramajit Raghav and his 52-year-old wife, Shakuntala Devi, reportedly gave birth to a healthy baby boy, Ranjeet, on Oct. 5, according to the Times of India. Just two years ago, Raghav set the world record when he and Devi gave birth to their first son, Vikramajeet. "I didn't take any medicine. ... I just prayed to God to complete my family, either a boy or a girl," Raghav told the paper. India is often the source of unusual stories about a person's age. However, the life expectancy of the average Indian actually falls into the lower-third of UN global statistics (139 out of 194 counties), at 64.7 years. The average Indian man lives 63.2 years. By comparison, Japan has the longest worldwide life expectancy, with its residents living an average of 82.7 years. The US comes in at No. 38, with Americans living an average of 79.2 years. While male fertility  rates are not as directly correlated to age as are women's, male fertility rates do decline with age, according to a study published in the 2004 issue of Human Reproduction Update. Raghav says that he credits his diet of butter, milk and almonds for his longevity, along with abstaining from drugs and alcohol.  "I feel lucky to have two healthy sons. It will be tough, but I'm a happy man," he said. Interestingly, the previous record holder for world's oldest dad was also Indian: Nanu Ram Jog, who reportedly fathered his 21st at the age of 90. For his part, Raghav doesn't plan to set any more paternal records. He said. "I don't want more children, we can't afford it." 
 Answer: improving life expectancy of Indians.

Solution: Raghav set the world record for   _  .
