Problem: As the economy and the middle class expanded, there was an increasing number of amateur musicians. One manifestation of this involved women, who became more involved with music on a social level. Women were already engaged in professional roles as singers, and increased their presence in the amateur performers' scene, especially with keyboard music. Music publishers begin to print music that amateurs could understand and play. The majority of the works that were published were for keyboard, voice and keyboard, and chamber ensemble. After these initial genres were popularized, from the mid-century on, amateur groups sang choral music, which then became a new trend for publishers to capitalize on. The increasing study of the fine arts, as well as access to amateur-friendly published works, led to more people becoming interested in reading and discussing music. Music magazines, reviews, and critical works which suited amateurs as well as connoisseurs began to surface.
Which economic class expansion led to the emergence of music magazines and reviews?
The answer is the following: middle

Problem: Asian Americans in New York City, according to the 2010 Census, number more than one million, greater than the combined totals of San Francisco and Los Angeles. New York contains the highest total Asian population of any U.S. city proper. The New York City borough of Queens is home to the state's largest Asian American population and the largest Andean (Colombian, Ecuadorian, Peruvian, and Bolivian) populations in the United States, and is also the most ethnically diverse urban area in the world. The Chinese population constitutes the fastest-growing nationality in New York State; multiple satellites of the original Manhattan Chinatown (紐約華埠), in Brooklyn (布鲁克林華埠), and around Flushing, Queens (法拉盛華埠), are thriving as traditionally urban enclaves, while also expanding rapidly eastward into suburban Nassau County (拿騷縣) on Long Island (長島), as the New York metropolitan region and New York State have become the top destinations for new Chinese immigrants, respectively, and large-scale Chinese immigration continues into New York City and surrounding areas. In 2012, 6.3% of New York City was of Chinese ethnicity, with nearly three-fourths living in either Queens or Brooklyn, geographically on Long Island. A community numbering 20,000 Korean-Chinese (Chaoxianzu (Chinese: 朝鲜族) or Joseonjok (Hangul: 조선족)) is centered in Flushing, Queens, while New York City is also home to the largest Tibetan population outside China, India, and Nepal, also centered in Queens. Koreans made up 1.2% of the city's population, and Japanese 0.3%. Filipinos were the largest Southeast Asian ethnic group at 0.8%, followed by Vietnamese, who made up 0.2% of New York City's population in 2010. Indians are the largest South Asian group, comprising 2.4% of the city's population, with Bangladeshis and Pakistanis at 0.7% and 0.5%, respectively.
