Problem: Please answer a question about the following article about Gamal Abdel Nasser:
After the three-year transition period ended with Nasser's official assumption of power, his domestic and independent foreign policies increasingly collided with the regional interests of the UK and France. The latter condemned his strong support for Algerian independence, and the UK's Eden government was agitated by Nasser's campaign against the Baghdad Pact. In addition, Nasser's adherence to neutralism regarding the Cold War, recognition of communist China, and arms deal with the Eastern bloc alienated the United States. On 19 July 1956, the US and UK abruptly withdrew their offer to finance construction of the Aswan Dam, citing concerns that Egypt's economy would be overwhelmed by the project.
What communist country did Nasser and Egypt recognize?
A: China
Problem: Please answer a question about the following article about Mandolin:
The mandolin's popularity in the United States was spurred by the success of a group of touring young European musicians known as the Estudiantina Figaro, or in the United States, simply the "Spanish Students." The group landed in the U.S. on January 2, 1880 in New York City, and played in Boston and New York to wildly enthusiastic crowds. Ironically, this ensemble did not play mandolins but rather bandurrias, which are also small, double-strung instruments that resemble the mandolin. The success of the Figaro Spanish Students spawned other groups who imitated their musical style and costumes. An Italian musician, Carlo Curti, hastily started a musical ensemble after seeing the Figaro Spanish Students perform; his group of Italian born Americans called themselves the "Original Spanish Students," counting on the American public to not know the difference between the Spanish bandurrias and Italian mandolins. The imitators' use of mandolins helped to generate enormous public interest in an instrument previously relatively unknown in the United States.
Where did the Estudiantina Figaro play? 
A: Boston and New York

South Oklahoma City is generally more blue collar working class and significantly more industrial, having grown up around the Stockyards and meat packing plants at the turn of the century, and is currently the center of the city's rapidly growing Latino community.
Which side is more urban and fashionable?
A:
North Oklahoma City
