Task: Question Generation
Input (English): The ruby slippers are the magic pair of shoes worn by Dorothy Gale as played by Judy Garland in the classic 1939 MGM musical movie The Wizard of Oz. Because of their iconic stature, the ruby slippers are now considered among the most treasured and valuable items of film memorabilia. As is customary for important props, a number of pairs were made for the film, though the exact number is unknown. Five pairs are known to have survived; one pair was stolen in August 2005 and has never been recovered.
Output (English): did they ever find the stolen ruby slippers?
