Input: Consider Input: John Knox (1505–1572), a Scot who had spent time studying under Calvin in Geneva, returned to Scotland and urged his countrymen to reform the Church in line with Calvinist doctrines. After a period of religious convulsion and political conflict culminating in a victory for the Protestant party at the Siege of Leith the authority of the Church of Rome was abolished in favour of Reformation by the legislation of the Scottish Reformation Parliament in 1560. The Church was eventually organised by Andrew Melville along Presbyterian lines to become the national Church of Scotland. King James VI and I moved the Church of Scotland towards an episcopal form of government, and in 1637, James' successor, Charles I and William Laud, the Archbishop of Canterbury, attempted to force the Church of Scotland to use the Book of Common Prayer. What resulted was an armed insurrection, with many Scots signing the Solemn League and Covenant. The Covenanters would serve as the government of Scotland for nearly a decade, and would also send military support to the Parliamentarians during the English Civil War. Following the restoration of the monarchy in 1660, Charles II, despite the initial support that he received from the Covenanters, reinstated an episcopal form of government on the church.

Output: What year did John Knox past away?


Input: Consider Input: Sisvel S.p.A. and its U.S. subsidiary Audio MPEG, Inc. previously sued Thomson for patent infringement on MP3 technology, but those disputes were resolved in November 2005 with Sisvel granting Thomson a license to their patents. Motorola followed soon after, and signed with Sisvel to license MP3-related patents in December 2005. Except for three patents, the US patents administered by Sisvel had all expired in 2015, however (the exceptions are: U.S. Patent 5,878,080, expires February 2017, U.S. Patent 5,850,456, expires February 2017 and U.S. Patent 5,960,037, expires 9. April 2017.

Output: Who was sued for patent infringement on MP3 technology?


Input: Consider Input: The rapid expansion of the Rus' to the south led to conflict and volatile relationships with the Khazars and other neighbors on the Pontic steppe. The Khazars dominated the Black Sea steppe during the 8th century, trading and frequently allying with the Byzantine Empire against Persians and Arabs. In the late 8th century, the collapse of the Göktürk Khaganate led the Magyars and the Pechenegs, Ugric and Turkic peoples from Central Asia, to migrate west into the steppe region, leading to military conflict, disruption of trade, and instability within the Khazar Khaganate. The Rus' and Slavs had earlier allied with the Khazars against Arab raids on the Caucasus, but they increasingly worked against them to secure control of the trade routes.


Output: What led to constant problems with the Khazars?
