Task: Question Generation
Input (English): Passage: It has been estimated that during the course of six hours in one day, 22 March 1739, approximately 20,000 to 30,000 Indian men, women and children were slaughtered by the Afsharid troops during the massacre in the city.  Exact casualty figures are uncertain, as after the massacre, the bodies of the victims were simply buried in mass burial pits or cremated in grand funeral pyres without any proper record being made of the numbers cremated or buried. In addition, some 10,000 women and children were taken slaves, according to a representative of the Dutch East India Company in Delhi.
