Input: Consider Input: Passage: In the summer of 1521, Luther widened his target from individual pieties like indulgences and pilgrimages to doctrines at the heart of Church practices. In On the Abrogation of the Private Mass, he condemned as idolatry the idea that the mass is a sacrifice, asserting instead that it is a gift, to be received with thanksgiving by the whole congregation. His essay On Confession, Whether the Pope has the Power to Require It rejected compulsory confession and encouraged private confession and absolution, since 'every Christian is a confessor.' In November, Luther wrote The Judgement of Martin Luther on Monastic Vows. He assured monks and nuns that they could break their vows without sin, because vows were an illegitimate and vain attempt to win salvation. Question: After rejecting compulsory confession, what did Luther call for?

Output: private confession and absolution


Input: Consider Input: Passage: The most frequent musical contributor during the first 15 years was Dudley Simpson, who is also well known for his theme and incidental music for Blake's 7, and for his haunting theme music and score for the original 1970s version of The Tomorrow People.

He also made a cameo appearance in The Talons of Weng-Chiang (as a Music hall conductor). Question: Who was the most frequent musical contributor to Doctor Who in the first 15 years of the show?

Input: Consider Input: Passage: Some civil disobedients feel it is incumbent upon them to accept punishment because of their belief in the validity of the social contract, which is held to bind all to obey the laws that a government meeting certain standards of legitimacy has established, or else suffer the penalties set out in the law. Other civil disobedients who favor the existence of government still don't believe in the legitimacy of their particular government, or don't believe in the legitimacy of a particular law it has enacted. And still other civil disobedients, being anarchists, don't believe in the legitimacy of any government, and therefore see no need to accept punishment for a violation of criminal law that does not infringe the rights of others. Question: What do some people protest against?
Output: legitimacy of a particular law
