Task: Question Generation
Input (English): Detroit is served by various private schools, as well as parochial Roman Catholic schools operated by the Archdiocese of Detroit. As of 2013[update] there are four Catholic grade schools and three Catholic high schools in the City of Detroit, with all of them in the city's west side. The Archdiocese of Detroit lists a number of primary and secondary schools in the metro area as Catholic education has emigrated to the suburbs. Of the three Catholic high schools in the city, two are operated by the Society of Jesus and the third is co-sponsored by the Sisters, Servants of the Immaculate Heart of Mary and the Congregation of St. Basil.
Output (English): How many Catholic grade schools are in Detroit?
