PROBLEM: What does the S in "PBS" stand for?, Context: New York is also a major center for non-commercial educational media. The oldest public-access television channel in the United States is the Manhattan Neighborhood Network, founded in 1971. WNET is the city's major public television station and a primary source of national Public Broadcasting Service (PBS) television programming. WNYC, a public radio station owned by the city until 1997, has the largest public radio audience in the United States.

SOLUTION: Service

PROBLEM: what is the last ethnic description mentioned?, Context: President Franklin D. Roosevelt promoted a "good neighbor" policy that sought better relations with Mexico. In 1935 a federal judge ruled that three Mexican immigrants were ineligible for citizenship because they were not white, as required by federal law. Mexico protested, and Roosevelt decided to circumvent the decision and make sure the federal government treated Hispanics as white. The State Department, the Census Bureau, the Labor Department, and other government agencies therefore made sure to uniformly classify people of Mexican descent as white. This policy encouraged the League of United Latin American Citizens in its quest to minimize discrimination by asserting their whiteness.

SOLUTION: whiteness

PROBLEM: How were the jazz records from Prestige Records made?, Context: Some recordings, such as books for the blind, were pressed at 16 2⁄3 rpm. Prestige Records released jazz records in this format in the late 1950s; for example, two of their Miles Davis albums were paired together in this format. Peter Goldmark, the man who developed the 33 1⁄3 rpm record, developed the Highway Hi-Fi 16 2⁄3 rpm record to be played in Chrysler automobiles, but poor performance of the system and weak implementation by Chrysler and Columbia led to the demise of the 16 2⁄3 rpm records. Subsequently, the 16 2⁄3 rpm speed was used for narrated publications for the blind and visually impaired, and were never widely commercially available, although it was common to see new turntable models with a 16 rpm speed setting produced as late as the 1970s.

SOLUTION:
pressed at 16 2⁄3 rpm
