Question: 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?

Answer: 1979


Question: Passage: In 1968, ABC took advantage of new FCC ownership regulations that allowed broadcasting companies to own a maximum of seven radio stations nationwide in order to purchase Houston radio stations KXYZ and KXYZ-FM for $1 million in shares and $1.5 million in bonds. That year, Roone Arledge was named president of ABC Sports; the company also founded ABC Pictures, a film production company which released its first picture that year, the Ralph Nelson-directed Charly. It was renamed ABC Motion Pictures in 1979; the unit was dissolved in 1985. The studio also operated two subsidiaries, Palomar Pictures International and Selmur Pictures. In July 1968, ABC continued its acquisitions in the amusement parks sector with the opening of ABC Marine World in Redwood City, California; that park was sold in 1972 and demolished in 1986, with the land that occupied the park later becoming home to the headquarters of Oracle Corporation. Question: Where was ABC Marine World opened?

Answer: Redwood City, California


Question: Passage: The last opus number that Chopin himself used was 65, allocated to the Cello Sonata in G minor. He expressed a deathbed wish that all his unpublished manuscripts be destroyed. At the request of the composer's mother and sisters, however, his musical executor Julian Fontana selected 23 unpublished piano pieces and grouped them into eight further opus numbers (Opp. 66–73), published in 1855. In 1857, 17 Polish songs that Chopin wrote at various stages of his life were collected and published as Op. 74, though their order within the opus did not reflect the order of composition. Question: How many unfinished pieces did Julian Fontana make into eight more opus numbers?

Answer:
23
