Task: Question Generation
Input (English): Passage: The Protestant lands at the beginning of the 17th century were concentrated in Northern Europe, with territories in Germany, Scandinavia, England, Scotland, and areas of France, the Low Countries, Switzerland, Kingdom of Hungary and Poland. Heavy fighting, in some cases a continuation of the religious conflicts of the previous centuries, was seen, particularly in the Low Countries and the Electorate of the Palatinate . In Ireland there was a concerted attempt to create "plantations" of Protestant settlers in what was a predominantly Catholic country, and fighting with a religious dimension was serious in the 1640s and 1680s. In France the settlement proposed by the Edict of Nantes was whittled away, to the disadvantage of the Huguenot population, and the edict was revoked in 1685. Protestant Europe was largely divided into Lutheran and Reformed  areas, with the Church of England maintaining a separate position. Efforts to unify Lutherans and Calvinists had little success; and the ecumenical ambition to overcome the schism of the Protestant Reformation remained almost entirely theoretical. The Church of England under William Laud made serious approaches to figures in the Orthodox Church, looking for common ground. Within Calvinism an important split occurred with the rise of Arminianism; the Synod of Dort of 1618-19 was a national gathering but with international repercussions, as the teaching of Arminius was firmly rejected at a meeting to which Protestant theologians from outside the Netherlands were invited. The Westminster Assembly of the 1640s was another major council dealing with Reformed theology, and some of its works continue to be important to Protestant denominations.
Output (English): How many countries contained concentrated Portestant lands at the beginning of the 17th century?
