Here is a question about this article: Chinese men entered the United States as laborers, primarily on the West Coast and in western territories. Following the Reconstruction era, as blacks set up independent farms, white planters imported Chinese laborers to satisfy their need for labor. In 1882, the Chinese Exclusion Act was passed, and Chinese workers who chose to stay in the U.S. were unable to have their wives join them. In the South, some Chinese married into the black and mulatto communities, as generally discrimination meant they did not take white spouses. They rapidly left working as laborers, and set up groceries in small towns throughout the South. They worked to get their children educated and socially mobile.
What is the answer to this question: What did racial bias generally mean for Chinese people?

So... they did not take white spouses

Here is a question about this article: Chopin also endowed popular dance forms with a greater range of melody and expression. Chopin's mazurkas, while originating in the traditional Polish dance (the mazurek), differed from the traditional variety in that they were written for the concert hall rather than the dance hall; "it was Chopin who put the mazurka on the European musical map." The series of seven polonaises published in his lifetime (another nine were published posthumously), beginning with the Op. 26 pair (published 1836), set a new standard for music in the form. His waltzes were also written specifically for the salon recital rather than the ballroom and are frequently at rather faster tempos than their dance-floor equivalents.
What is the answer to this question: What dance music of Chopin was written more for recitals than ballrooms?

So... waltzes

Here is a question about this article: In 1937, Imperial Airways and Pan American World Airways began operating scheduled flying-boat airline services from New York and Baltimore to Darrell's Island, Bermuda. In 1948, regularly scheduled commercial airline service by land-based aeroplanes began to Kindley Field (now L.F. Wade International Airport), helping tourism to reach its peak in the 1960s1970s. By the end of the 1970s, international business had supplanted tourism as the dominant sector of Bermuda's economy (see Economy of Bermuda).
What is the answer to this question: What helped tourism grow to new heights in the 1960-1970's?

So...
regularly scheduled commercial airline service by land-based aeroplanes
