Question: When was the country that was represented particularly well in the hip hop movement founded? Passage:Latinos, particularly Puerto Ricans, were at the forefront of the hip hop movement, however; they have often been forgotten in conversation. Nonetheless, we can see the presence and influence of Latinos in hip hop when we think about artist like: Africa Bambaataa & the members of the Zulu Nation (1960s), Latino DJ, DJ Disco Wiz (aka first Latino DJ in hip hop) & DJ Grandmaster Caz came together to form the Mighty Force (1974), DJ Charlie Chase of the Cold Crush Brothers (1975), Lee Quiñones & Lady Pink (1970s), and various others have allowed for Latinos to have a part in hip hop culture and hip hop history. Latina's also had a huge role in hip hop, women who were not on the hip hop stage take part in: the influence and making of music and hip hop performance, dancing of music, and graffiti art. Today we see Latinas like: La Caballota aka Ivy Queen (1995), Ana Bijoux (1995), Angie Martinez: "The Voice of New York" (1996), Hurricane G aka Gloria Rodriguez (1997), Mala Rodríguez (1990s), Lisa M: "The Queen of Spanish Rap" (1988), Nina Dioz (2009), Snow Tha Product aka Claudia Feliciano (2011), Mélony Redondo: MelyMel (2018) have been women who have all taken the stage and made their mark as Latina and Afro-Latina rappers/artist in the hip hop world.

Question: Which place is older, Chernihiv or Lutsk? Passage:In 1180, Ingvar Yaroslavich joined Ryurik Rostislavich in his struggle against Sviatoslav Vsevolodovich of Chernihiv. According to the Tale of Igor's Campaign, Ingvar was a brave man, however, he never wanted to irritate his powerful neighbors. In 1183, for instance, Ingvar refused to accommodate Vladimir II Yaroslavich in Dorogobuzh, who had been banished from Halych. It appears that Ingvar was wary of Yaroslav Osmomysl, Vladimir Yaroslavich's father. Soon after this, Ingvar took the place of his older brother Vsevolod Yaroslavich as the ruler of Lutsk. In 1202, Ingvar was appointed ruler of Kiev instead of the ousted Ryurik Rostislavich in accordance with a deal between Roman Mstislavich of Halych and Vsevolod the Big Nest, Grand Prince of Vladimir. Ryurik, however, would regain Kiev that same year with the help of the Olgovichs and polovtsy. In 1204, Ingvar took part in capturing the city of Volodymyr-Volyns'kyi together with Alexander of Belz. He was appointed ruler of the city on the spot, but was soon replaced by Alexander due to boyars' discontent. In 1208–1211, Ingvar sent his son to assist Daniil Romanovich in his struggle against the sons of Igor Sviatoslavich of Novhorod-Siverskyi. In 1212, Ingvar and Mstislav Romanovich attacked Vsevolod Sviatoslavich and captured Kiev. After a battle near Belgorod Ingvar voluntarily ceded Kiev to Mstislav Romanovich and left for Lutsk.
