PROBLEM: Passage: Ibrahim was born in Cape Town on 9 October 1934, and was baptized Adolph Johannes Brand. He attended Trafalgar High School in Cape Town's District Six, and began piano lessons at the age of seven, making his professional debut at 15. He is of mixed-race heritage, making him a Coloured person according to the South African government. His mother played piano in a church, the musical style of which would remain an influence; in addition, he learned to play several genres of music during his youth in Cape Town, including marabi, mbaqanga, and American jazz. He became well known in jazz circles in Cape Town and Johannesburg. In 1959 and 1960, Ibrahim played with the Jazz Epistles group in Sophiatown, alongside saxophonist Kippie Moeketsi, trumpeter Hugh Masekela, trombonist Jonas Gwangwa (who were all in the orchestra of the musical King Kong that opened in Johannesburg in February 1959), bassist Johnny Gertze and drummer Makaya Ntshoko; in January 1960, the six musicians went into the Gallo studio and recorded the first full-length jazz LP by Black South African musicians, Jazz Epistle Verse One, with 500 copies being produced. Although the group avoided explicitly political activity, the apartheid government was suspicious of it and other jazz groups, and targeted them heavily during the increase in state repression following the Sharpeville massacre, and eventually, the Jazz Epistles broke up.

PROBLEM: Passage: Columbia (; ) is the female personification of the United States. It was also a historical name used to describe the Americas and the New World. It has given rise to the names of many persons, places, objects, institutions and companies; for example: Columbia University, the District of Columbia (the national capital of the United States), and the ship Columbia Rediviva, which would give its name to the Columbia River. Images of the Statue of Liberty largely displaced personified Columbia as the female symbol of the United States by around 1920, although Lady Liberty was seen as an aspect of Columbia. The District of Columbia is named after the personification, as is the traditional patriotic hymn "Hail Columbia", which is the official vice presidential anthem of the United States Vice President.
