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: Agatha Christie (1890-1976) was born Agatha May Clarissa Miller in Devon, England in 1890, the youngest of three children in a conservative, well-to-do family. Taught at home by a governess and tutors, as a child Agatha Christie never attended school. She became skillful at creating games to keep herself occupied at a very young age. A _ l child, unable to adequately express her feelings, she first turned to music as a means of expression and, later in life, to writing. In 1914, at the age of 24, she married Archie Christie, a World War I fighter pilot. While he was off at war, she worked as a nurse. It was while working in a hospital during the war that Christie first came up with the idea of writing a detective novel. Although it was completed in a year, it wasn't published until 1920, five years later. "The mysterious Affair at Styles" gave the world the unique Hercule Poirot, a retired Belgian police officer who was to become one of the most enduring characters in all of fiction. With his waxed moustache and his "little grey cell," he was "meticulous (careful to do things correctly), a tidy little man, always neat, orderly and a bit absurd." Christie wrote more than 30 novels featuring Poirot. Among the most popular were" The Murder of Roger Ackroyd"(1926), "Murder on the Orient Expredd"(1934), and "Death on the Nile" (1937). Another of Christie's most well-known and beloved characters was introduced in "Murder at the Vicarage" in 1930. Miss Jane Marple, an elderly single in the old- fashioned English village of St. Mary Mead, solved all manner of mysteries with intense concentration and instinct. Christies ultimately (finally)became the acknowledged Queen of the Golden Age. In all, she wrote over 66 novel, numerous short stories and screenplays, and a series of romantic novels using the pen name Mary Westmacott. Several of her works were made into successful feature films, the most notable being Murder on the Orient Express (1974). In short, she is the single most popular mystery writer of all time. In 1971 she was awarded the high honor of becoming a Dame of the British Empire.
