Problem: Adult contemporary music:

In response to the pressure on Hot AC, a new kind of AC format cropped up among American radio recently. The urban adult contemporary format (a term coined by Barry Mayo) usually attracts a large number of African Americans and sometimes Caucasian listeners through playing a great deal of R&B (without any form of rapping), gospel music, classic soul and dance music (including disco).

Who invented the term "urban adult contemporary format"?

A: Barry Mayo


Problem: Circadian rhythm:

The primary circadian "clock" in mammals is located in the suprachiasmatic nucleus (or nuclei) (SCN), a pair of distinct groups of cells located in the hypothalamus. Destruction of the SCN results in the complete absence of a regular sleep–wake rhythm. The SCN receives information about illumination through the eyes. The retina of the eye contains "classical" photoreceptors ("rods" and "cones"), which are used for conventional vision. But the retina also contains specialized ganglion cells that are directly photosensitive, and project directly to the SCN, where they help in the entrainment (synchronization) of this master circadian clock.

Where are these cell groups found in humans?

A: hypothalamus


Problem: Compact disc:

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 code—specifications 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 13–16 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.

Where was the Philips Introduce Compact disc conference held?

A: Eindhoven, Netherlands


Problem: Northwestern University:

In 1998, two former Northwestern basketball players were charged and convicted for sports bribery as a result of being paid to shave points in games against three other Big Ten schools during the 1995 season. The football team became embroiled in a different betting scandal later that year when federal prosecutors indicted four former players for perjury related to betting on their own games. In August 2001, Rashidi Wheeler, a senior safety, collapsed and died during practice from an asthma attack. An autopsy revealed that he had ephedrine, a stimulant banned by the NCAA, in his system, which prompted Northwestern to investigate the prevalence of stimulants and other banned substances across all of its athletic programs. In 2006, the Northwestern women's soccer team was suspended and coach Jenny Haigh resigned following the release of images of alleged hazing.

What did federal prosecutors indict four former players for in a separate betting scandal?

A:
perjury related to betting on their own games
