Problem: In 1991, there were only two proposals available that could be completely assessed for an MPEG audio standard: Musicam (Masking pattern adapted Universal Subband Integrated Coding And Multiplexing) and ASPEC (Adaptive Spectral Perceptual Entropy Coding). The Musicam technique, as proposed by Philips (the Netherlands), CCETT (France) and Institut fur Rundfunktechnik (Germany) was chosen due to its simplicity and error robustness, as well as its low computational power associated with the encoding of high quality compressed audio. The Musicam format, based on sub-band coding, was the basis of the MPEG Audio compression format (sampling rates, structure of frames, headers, number of samples per frame).
How many proposals were available in 1991?
The answer is the following: two

Problem: Current manager, Roberto Martinez, is the fourteenth permanent holder of the position since it was established in 1939. There have also been four caretaker managers, and before 1939 the team was selected by either the club secretary or by committee. The club's longest-serving manager has been Harry Catterick, who was in charge of the team from 196173, taking in 594 first team matches. The Everton manager to win most domestic and international trophies is Howard Kendall, who won two Division One championships, the 1984 FA Cup, the 1984 UEFA Cup Winners' Cup, and three Charity Shields.
Which Everton manager won the most domestic and international trophies during his time?
The answer is the following: Howard Kendall

Problem: The immediate cause of the riots is unclear, with many commentators citing the killing of ten Burmese Muslims by ethnic Rakhine after the rape and murder of a Rakhine woman as the main cause. Whole villages have been "decimated". Over 300 houses and a number of public buildings have been razed. According to Tun Khin, the president of the Burmese Rohingya Organisation UK (BROUK), as of 28 June 2012, 650 Rohingyas have been killed, 1,200 are missing, and more than 80,000 have been displaced. According to the Myanmar authorities, the violence, between ethnic Rakhine Buddhists and Rohingya Muslims, left 78 people dead, 87 injured, and thousands of homes destroyed. It displaced more than 52,000 people.
What was believed to be one of the Burma reasons for the unrest in 2012 ?
The answer is the following: many commentators citing the killing of ten Burmese Muslims by ethnic Rakhine

Problem: Ann Arbor's "Tree Town" nickname stems from the dense forestation of its parks and residential areas. The city contains more than 50,000 trees along its streets and an equal number in parks. In recent years, the emerald ash borer has destroyed many of the city's approximately 10,500 ash trees. The city contains 157 municipal parks ranging from small neighborhood green spots to large recreation areas. Several large city parks and a university park border sections of the Huron River. Fuller Recreation Area, near the University Hospital complex, contains sports fields, pedestrian and bike paths, and swimming pools. The Nichols Arboretum, owned by the University of Michigan, is a 123-acre (50 ha) arboretum that contains hundreds of plant and tree species. It is on the city's east side, near the university's Central Campus. Located across the Huron River just beyond the university's North Campus is the university's Matthaei Botanical Gardens, which contains 300 acres of gardens and a large tropical conservatory.
What is the name of the Arboretum owned by the University of Michigan?
The answer is the following:
Nichols Arboretum
