[Q]: Passage: The nationalist parties, in turn, demanded devolution to their respective constituent countries in return for their supporting the government. When referendums for Scottish and Welsh devolution were held in March 1979 Welsh devolution was rejected outright while the Scottish referendum returned a narrow majority in favour without reaching the required threshold of 40% support. When the Labour government duly refused to push ahead with setting up the proposed Scottish Assembly, the SNP withdrew its support for the government: this finally brought the government down as it triggered a vote of confidence in Callaghan's government that was lost by a single vote on 28 March 1979, necessitating a general election. Question: In what year was the Scottish and Welsh devolution rejected?
[A]: 1979

[Q]: Passage: As of 2012[update], there are over 3.5 million vehicles operating in the city, of which 74% are two-wheelers, 15% cars and 3% three-wheelers. The remaining 8% include buses, goods vehicles and taxis. The large number of vehicles coupled with relatively low road coverageroads occupy only 9.5% of the total city area:79has led to widespread traffic congestion especially since 80% of passengers and 60% of freight are transported by road.:3 The Inner Ring Road, the Outer Ring Road, the Hyderabad Elevated Expressway, the longest flyover in India, and various interchanges, overpasses and underpasses were built to ease the congestion. Maximum speed limits within the city are 50 km/h (31 mph) for two-wheelers and cars, 35 km/h (22 mph) for auto rickshaws and 40 km/h (25 mph) for light commercial vehicles and buses. Question: In 2012 how many vehicles were driving in Hyderabad?
[A]: 3.5 million

[Q]: Passage: In addition to the Vedas, the principal texts of Hinduism, the core themes of the Sanskrit epics Ramayana and Mahabharata are said to have their ultimate origins during this period. The Mahabharata remains, today, the longest single poem in the world. Historians formerly postulated an "epic age" as the milieu of these two epic poems, but now recognize that the texts (which are both familiar with each other) went through multiple stages of development over centuries. For instance, the Mahabharata may have been based on a small-scale conflict (possibly about 1000 BCE) which was eventually "transformed into a gigantic epic war by bards and poets". There is no conclusive proof from archaeology as to whether the specific events of the Mahabharat have any historical basis. The existing texts of these epics are believed to belong to the post-Vedic age, between c. 400 BCE and 400 CE. Some even attempted to date the events using methods of archaeoastronomy which have produced, depending on which passages are chosen and how they are interpreted, estimated dates ranging up to mid 2nd millennium BCE. Question: Which Vedic text is the longest single poem on Earth?
[A]:
Mahabharata
