Question: What year did Carroll participate in the Make Poverty History protest? Passage:When aged 16, Carroll fund-raised with fellow activists to travel to Edinburgh for the Make Poverty History protest. He contested the 2011 Belfast West by-electiontriggered by the resignation of Gerry Adamsfor the People Before Profit, and won 7.6% of the vote. At the 2014 Belfast City Council election he gained one of the seven seats in the Black Mountain electoral area from Sinn Fein, coming third. Following his election, he said that he did not describe himself as a nationalist or a unionist, instead choosing to identify as a socialist. He said: "There is a lot of anger in West Belfast at the minute over the situation at Royal Victoria Hospital's A&E, the privatisation of leisure centres and the Casement Park issues...residents have been trampled on". He contested Belfast West again at the 2015 general election, this time coming second, gaining 19.2% of the vote and reducing the Sinn Fein majority from 57.1% to 35.0%.
