Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

[Q]: Question: What present day country was Pontus? Passage:According to the Georgian chronicles, Nana was "from a Greek territory, from Pontus, the daughter of Oligotos" whom Mirian married after his first wife died (in 292 according to Cyril Toumanoff). Nana bore Mirian two sons: Rev II, Varaz-Bakur and a daughter who married Peroz, the first Mihranid dynast of Gugark. Pontus here may refer to the Bosporan Kingdom, then a client state of the Roman Empire. Toumanoff has assumed that the name of Nana's father might have been a Georgian corruption of "Olympius" or "Olympus", a Bosporan dynast whose son Aurelius Valerius Sogus Olympianus, a Roman governor of Theodosia, is known from a Greek inscription of 306 dedicated to "the Most High God" on the occasion of the building of the Jewish "prayer house". Alternatively, Christian Settipani identifies Nana as a younger daughter of Theothorses, a Bosporan king.

[Q]: Question: Who designed Hans Klemm's first light aircraft? Passage:Hans Klemm's first light aircraft was the Daimler L15 and the L20 had much in common with it. Both were cantilever monoplanes with twin open, tandem cockpits and engines of very low power. The L20's low wing distinguished it from its predecessor and had the advantage of providing a low centre of gravity and better view during the landing approach as well as better protection for occupants in case of crash landings. The low-set wing also allowed a shorter undercarriage on the L20, which was otherwise like that of the L15 with the wheels independently mounted on pairs of centrally hinged V-struts and with vertical shock absorbing legs to the wing underside. Wheels were sometimes replaced by floats. Intended from the start for serial production, the L20's structure was simplified, with a pentagonal cross-section fuselage lacking the L15's rounded upper and lower surfaces. The fuselage was wooden framed with canvas covering. The overall strength of the structure, which had a safety factor of 12, was emphasised.

[Q]: Question: Which South African city that Ibrahim became a well known Jazz player has the highest population? 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.
