Q: Answer the question from the given passage. Your answer should be directly extracted from the passage, and it should be a single entity, name, or number, not a sentence.
Passage: Historically, the Methodist Church has supported the temperance movement. John Wesley warned against the dangers of drinking in his famous sermon, 'The Use of Money,' and in his letter to an alcoholic. At one time, Methodist ministers had to take a pledge not to drink and encouraged their congregations to do the same. Today the United Methodist Church states that it 'affirms our long-standing support of abstinence from alcohol as a faithful witness to God's liberating and redeeming love for persons.' In fact, the United Methodist Church uses unfermented grape juice in the sacrament of Holy Communion, thus 'expressing pastoral concern for recovering alcoholics, enabling the participation of children and youth, and supporting the church's witness of abstinence.' Moreover, in 2011 and 2012, The United Methodist Church's General Board of Church and Society called on all United Methodists to abstain from alcohol for Lent. Question: When did the UMC's General Board of Church and Society call on all United Methodists to abstain from alcohol for Lent?
A:
2011 and 2012
