Question: By the late 1950s, the motion picture business was again changing. The combination of the studio/theater-chain break-up and the rise of television saw the reduced audience size for cinema productions. The Music Corporation of America (MCA), then predominately a talent agency, had also become a powerful television producer, renting space at Republic Studios for its Revue Productions subsidiary. After a period of complete shutdown, a moribund Universal agreed to sell its 360-acre (1.5 km²) studio lot to MCA in 1958, for $11 million, renamed Revue Studios. MCA owned the studio lot, but not Universal Pictures, yet was increasingly influential on Universal's product. The studio lot was upgraded and modernized, while MCA clients like Doris Day, Lana Turner, Cary Grant, and director Alfred Hitchcock were signed to Universal Pictures contracts.
Is there an answer to this question: Where did MCA's Revue Productions subsidiary rent space?

Answer: Republic Studios


Question: DC systems (especially third-rail systems) are limited to relatively low voltages and this can limit the size and speed of trains and cannot use low-level platform and also limit the amount of air-conditioning that the trains can provide. This may be a factor favouring overhead wires and high-voltage AC, even for urban usage. In practice, the top speed of trains on third-rail systems is limited to 100 mph (160 km/h) because above that speed reliable contact between the shoe and the rail cannot be maintained.
Is there an answer to this question: What is not a factor favoring overhead wires and high-voltage AC?

Answer: unanswerable

Question: After 1800, cotton and tobacco became important export crops. The eastern half of the state, especially the Tidewater region, developed a slave society based on a plantation system and slave labor. Many free people of color migrated to the frontier along with their European-American neighbors, where the social system was looser. By 1810, nearly 3 percent of the free population consisted of free people of color, who numbered slightly more than 10,000. The western areas were dominated by white families, especially Scots-Irish, who operated small subsistence farms. In the early national period, the state became a center of Jeffersonian and Jacksonian democracy, with a strong Whig presence, especially in the West. After Nat Turner's slave uprising in 1831, North Carolina and other southern states reduced the rights of free blacks. In 1835 the legislature withdrew their right to vote.
Is there an answer to this question: Where did free black people migrate to because of the looser social system?

Answer:
the frontier
