Article: Anti-miscegenation laws were passed in most states during the 18th, 19th and early 20th centuries, but this did not prevent white slaveholders, their sons, or other powerful white men from taking slave women as concubines and having multiracial children with them. In California and the western US, there were greater numbers of Latino and Asian residents. These were prohibited from official relationships with whites. White legislators passed laws prohibiting marriage between European and Asian Americans until the 1950s.

Question: What were put in place to prevent the mix of races?
Ans: Anti-miscegenation laws

Article: In the spring of 1834, Chopin attended the Lower Rhenish Music Festival in Aix-la-Chapelle with Hiller, and it was there that Chopin met Felix Mendelssohn. After the festival, the three visited Dusseldorf, where Mendelssohn had been appointed musical director. They spent what Mendelssohn described as "a very agreeable day", playing and discussing music at his piano, and met Friedrich Wilhelm Schadow, director of the Academy of Art, and some of his eminent pupils such as Lessing, Bendemann, Hildebrandt and Sohn. In 1835 Chopin went to Carlsbad, where he spent time with his parents; it was the last time he would see them. On his way back to Paris, he met old friends from Warsaw, the Wodzinskis. He had made the acquaintance of their daughter Maria in Poland five years earlier, when she was eleven. This meeting prompted him to stay for two weeks in Dresden, when he had previously intended to return to Paris via Leipzig. The sixteen-year-old girl's portrait of the composer is considered, along with Delacroix's, as among Chopin's best likenesses. In October he finally reached Leipzig, where he met Schumann, Clara Wieck and Felix Mendelssohn, who organised for him a performance of his own oratorio St. Paul, and who considered him "a perfect musician". In July 1836 Chopin travelled to Marienbad and Dresden to be with the Wodzinski family, and in September he proposed to Maria, whose mother Countess Wodzinska approved in principle. Chopin went on to Leipzig, where he presented Schumann with his G minor Ballade. At the end of 1836 he sent Maria an album in which his sister Ludwika had inscribed seven of his songs, and his 1835 Nocturne in C-sharp minor, Op. 27, No. 1. The anodyne thanks he received from Maria proved to be the last letter he was to have from her.

Question: Where were Frederic's parents located at when he saw them for the final time in 1835?
Ans: Carlsbad

Article: The use of time is an important issue in understanding human behavior, education, and travel behavior. Time-use research is a developing field of study. The question concerns how time is allocated across a number of activities (such as time spent at home, at work, shopping, etc.). Time use changes with technology, as the television or the Internet created new opportunities to use time in different ways. However, some aspects of time use are relatively stable over long periods of time, such as the amount of time spent traveling to work, which despite major changes in transport, has been observed to be about 2030 minutes one-way for a large number of cities over a long period.

Question: What is a developing field of time related study?
Ans: Time-use research

Article: Chopin's qualities as a pianist and composer were recognized by many of his fellow musicians. Schumann named a piece for him in his suite Carnaval, and Chopin later dedicated his Ballade No. 2 in F major to Schumann. Elements of Chopin's music can be traced in many of Liszt's later works. Liszt later transcribed for piano six of Chopin's Polish songs. A less fraught friendship was with Alkan, with whom he discussed elements of folk music, and who was deeply affected by Chopin's death.

Question: In what suite did Schumann name a work for Chopin?
Ans:
Carnaval
