Serbo-Croatian was standardized in the mid-19th-century Vienna Literary Agreement by Croatian and Serbian writers and philologists, decades before a Yugoslav state was established. From the very beginning, there were slightly different literary Serbian and Croatian standards, although both were based on the same Shtokavian subdialect, Eastern Herzegovinian. In the 20th century, Serbo-Croatian served as the official language of the Kingdom of Yugoslavia (when it was called "Serbo-Croato-Slovenian"), and later as one of the official languages of the Socialist Federal Republic of Yugoslavia. The breakup of Yugoslavia affected language attitudes, so that social conceptions of the language separated on ethnic and political lines. Since the breakup of Yugoslavia, Bosnian has likewise been established as an official standard in Bosnia and Herzegovina, and there is an ongoing movement to codify a separate Montenegrin standard. Serbo-Croatian thus generally goes by the ethnic names Serbian, Croatian, Bosnian, and sometimes Montenegrin and Bunjevac.

Which language officially served the Kingdom of Yugoslavia?

The term "house music" is said to have originated from a Chicago club called The Warehouse, which existed from 1977 to 1983. Clubbers to The Warehouse were primarily black and gay, who came to dance to music played by the club's resident DJ Frankie Knuckles, whom fans refer to as the "godfather of house". After the Warehouse closed in 1983, the crowds went to Knuckles' new club, The Power Plant. In the Channel 4 documentary Pump Up The Volume, Knuckles remarks that the first time he heard the term "house music" was upon seeing "we play house music" on a sign in the window of a bar on Chicago's South Side. One of the people in the car with him joked, "you know, that's the kind of music you play down at the Warehouse!", and then everybody laughed. South-Side Chicago DJ Leonard "Remix" Roy, in self-published statements, claims he put such a sign in a tavern window because it was where he played music that one might find in one's home; in his case, it referred to his mother's soul & disco records, which he worked into his sets. Farley Jackmaster Funk was quoted as saying "In 1982, I was DJing at a club called The Playground and there was this kid named Leonard 'Remix' Roy who was a DJ at a rival club called The Rink. He came over to my club one night, and into the DJ booth and said to me, 'I've got the gimmick that's gonna take all the people out of your club and into mine it's called House music.' Now, where he got that name from or what made him think of it I don't know, so the answer lies with him."

who was the resident DJ at The Warehouse in Chicago?
Answer: Frankie Knuckles

Secondary education in the United States did not emerge until 1910, with the rise of large corporations and advancing technology in factories, which required skilled workers. In order to meet this new job demand, high schools were created, with a curriculum focused on practical job skills that would better prepare students for white collar or skilled blue collar work. This proved beneficial for both employers and employees, since the improved human capital lowered costs for the employer, while skilled employees received a higher wages.

When did secondary education emerge in the United States?
Answer:
1910
