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.

[EX Q]: Passage: Much of the work of the Scottish Parliament is done in committee. The role of committees is stronger in the Scottish Parliament than in other parliamentary systems, partly as a means of strengthening the role of backbenchers in their scrutiny of the government and partly to compensate for the fact that there is no revising chamber. The principal role of committees in the Scottish Parliament is to take evidence from witnesses, conduct inquiries and scrutinise legislation. Committee meetings take place on Tuesday, Wednesday and Thursday morning when Parliament is sitting. Committees can also meet at other locations throughout Scotland. Question: Where might committees meet outside of Parliament?
[EX A]: other locations throughout Scotland

[EX Q]: Passage: As in the House of Commons, a number of qualifications apply to being an MSP. Such qualifications were introduced under the House of Commons Disqualification Act 1975 and the British Nationality Act 1981. Specifically, members must be over the age of 18 and must be a citizen of the United Kingdom, the Republic of Ireland, one of the countries in the Commonwealth of Nations, a citizen of a British overseas territory, or a European Union citizen resident in the UK. Members of the police and the armed forces are disqualified from sitting in the Scottish Parliament as elected MSPs, and similarly, civil servants and members of foreign legislatures are disqualified. An individual may not sit in the Scottish Parliament if he or she is judged to be insane under the terms of the Mental Health (Care and Treatment) (Scotland) Act 2003. Question: How old most a person be to apply to be an MSP?
[EX A]: over the age of 18

[EX Q]: Passage: The heat required for boiling the water and supplying the steam can be derived from various sources, most commonly from burning combustible materials with an appropriate supply of air in a closed space (called variously combustion chamber, firebox). In some cases the heat source is a nuclear reactor, geothermal energy, solar energy or waste heat from an internal combustion engine or industrial process. In the case of model or toy steam engines, the heat source can be an electric heating element. Question: What is the usual source of heat for boiling water in the steam engine?
[EX A]:
burning combustible materials
