Example Input: Passage: On August 23, 1991,[a] Nintendo released the Super Nintendo Entertainment System, a redesigned version of the Super Famicom, in North America for US$199. The SNES was released in the United Kingdom and Ireland in April 1992 for GB£150, with a German release following a few weeks later. Most of the PAL region versions of the console use the Japanese Super Famicom design, except for labeling and the length of the joypad leads. The Playtronic Super NES in Brazil, although PAL, uses the North American design. Both the NES and SNES were released in Brazil in 1993 by Playtronic, a joint venture between the toy company Estrela and consumer electronics company Gradiente.
Example Output: What was a redesign of the Super NES?

Example Input: Passage: Following the Protestant Reformation, promoted by local reformer Martin Bucer, the principle of cuius regio, eius religio led to a certain amount of religious diversity in the highlands of northern Alsace. Landowners, who as "local lords" had the right to decide which religion was allowed on their land, were eager to entice populations from the more attractive lowlands to settle and develop their property. Many accepted without discrimination Catholics, Lutherans, Calvinists, Jews and Anabaptists. Multiconfessional villages appeared, particularly in the region of Alsace bossue. Alsace became one of the French regions boasting a thriving Jewish community, and the only region with a noticeable Anabaptist population. The schism of the Amish under the lead of Jacob Amman from the Mennonites occurred in 1693 in Sainte-Marie-aux-Mines. The strongly Catholic Louis XIV tried in vain to drive them from Alsace. When Napoleon imposed military conscription without religious exception, most emigrated to the American continent.
Example Output:
When did the Anabaptists split?
