Task: Question Generation
Input (English): Context : Since there are many periods in Snefru's reigns for which Egyptologists have few dates--only the years of the 2nd, 7th, 8th, 12th, 13th, 14th, 15th, 16th, 17th, 18th, 23rd and 24th count are known for Sneferu before one considers the years after his cattle counts--this pharaoh is most likely to have had a reign in excess of 30 years to manage to build three pyramids in his long rule but not 48 years since the cattle count was not regularly biannual during his kingship. 
Subject : Sneferu 
Relation : spouse
Output (English): What is Sneferu's spouse's name?
