Question: Question: "Which happened first, Heitaro Nakajima developed an early digital audio recorder or became general manager of Sony's audio department?" Context: "Heitaro Nakajima, who developed an early digital audio recorder within Japan's national public broadcasting organization NHK in 1970, became general manager of Sony's audio department in 1971. His team developed a digital PCM adaptor audio tape recorder using a Betamax video recorder in 1973. After this, in 1974 the leap to storing digital audio on an optical disc was easily made. Sony first publicly demonstrated an optical digital audio disc in September 1976. A year later, in September 1977, Sony showed the press a 30 cm disc that could play 60 minutes of digital audio (44,100 Hz sampling rate and 16-bit resolution) using MFM modulation. In September 1978, the company demonstrated an optical digital audio disc with a 150-minute playing time, 44,056 Hz sampling rate, 16-bit linear resolution, and cross-interleaved error correction codespecifications similar to those later settled upon for the standard Compact Disc format in 1980. Technical details of Sony's digital audio disc were presented during the 62nd AES Convention, held on 1316 March 1979, in Brussels. Sony's AES technical paper was published on 1 March 1979. A week later, on 8 March, Philips publicly demonstrated a prototype of an optical digital audio disc at a press conference called "Philips Introduce Compact Disc" in Eindhoven, Netherlands." Answer:
Answer: developed an early digital audio recorder

Question: Question: "What are the percentages of population versus undergraduate diplomas?" Context: "According to a study by Dr. Paul Brest, Hispanics or "Latinos" include immigrants who are descendants of immigrants from the countries comprising Central and South America. In 1991, Mexican Americans, Puerto Ricans, and Cuban Americans made up 80% of the Latino population in the United States. Latinos are disadvantaged compared to White Americans and are more likely to live in poverty. They are the least well educated major ethnic group and suffered a 3% drop in high school completion rate while African Americans experienced a 12% increase between 1975-1990. In 1990, they constituted 9% of the population, but only received 3.1% of the bachelors's degrees awarded. At times when it is favorable to lawmakers, Latinos were considered "white" by the Jim Crow laws during the Reconstruction. In other cases, according to Paul Brest, Latinos have been classified as an inferior race and a threat to white purity. Latinos have encountered considerable discrimination in areas such as employment, housing, and education. Brest finds that stereotypes continue to be largely negative and many perceive Latinos as "lazy, unproductive, and on the dole." Furthermore, native-born Latino-Americans and recent immigrants are seen as identical since outsiders tend not to differentiate between Latino groups." Answer:
Answer: 9% of the population, but only received 3.1% of the bachelors's degrees awarded

Question: Question: "Where is the university that has ranked 76?" Context: "RMIT University was also ranked among the top 51100 universities in the world in the subjects of: accounting, Business and Management, communication and media studies, computer science and information systems. The Swinburne University of Technology, based in the inner city Melbourne suburb of Hawthorn is ranked 76100 in the world for Physics by the Academic Ranking of World Universities making Swinburne the only Australian university outside the Group of Eight to achieve a top 100 rating in a science discipline. Deakin University maintains two major campuses in Melbourne and Geelong, and is the third largest university in Victoria. In recent years, the number of international students at Melbourne's universities has risen rapidly, a result of an increasing number of places being made available to full fee paying students. Education in Melbourne is overseen by the Victorian Department of Education and Early Childhood Development (DEECD), whose role is to 'provide policy and planning advice for the delivery of education'." Answer:
Answer:
Hawthorn
