Take the following as truth: On the west bank of the river set in a desert landscape is the seventh-century Coptic monastery of St. Simeon now sadly in ruins, and the Mausoleum of the Aga Khan (1877 1957), spiritual leader of the Ismaili Muslim sect.
Then the following statement: "Aga Khan had many Ismaili Muslim followers that contributed to constructing his mausoleum." is true, false, or inconclusive?
