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.

Question: Where do the Premier League team that signed Rodriguez to a four-year contract play their home games? Passage:On 28 August 2015, Rodriguez signed a four-year contract with Everton of the Premier League for a reported fee of 500,000. Manager Roberto Martinez said that he would likely be put into the first team due to his experience in top-flight football in his homeland. However, Rodriguez made his debut for the under-21 team on 7 September. In his debut, he would head in Ryan Ledson's cross to open a 30 home win over Preston North End in the Lancashire Senior Cup. Fifteen days later, he was included in the senior squad for the first time, but remained on the bench as an unused substitute in a 21 win away to Reading in the second round of the League Cup. Rodriguez made his Everton first team debut on 9 January 2016 in the third round of the FA Cup when he replaced Aaron Lennon for the final minute of a 20 win over Dagenham & Redbridge at Goodison Park.

Question: What age was Richard Crossman when Llewelyn-Davies received her life peer as a Baroness? Passage:Llewelyn-Davies entered the civil service in 1940 and served in the Ministry of War Transport, the Foreign Office, the Air Ministry and the Commonwealth Relations Office. She resigned to contest the Wolverhampton South-West parliamentary seat for Labour during the 1951 general election, but was defeated by the incumbent Conservative Enoch Powell. She subsequently unsuccessfully contested the Wandsworth Central seat in 1955 and 1959, but didn't stand for parliament again. With support of those in the Wilson government and the backing of close friend Richard Crossman, who described her in his diaries as "the real politician" when her husband was elevated to the peerage, she was created a life peer as Baroness Llewelyn-Davies of Hastoe, of Hastoe in the County of Hertfordshire on 29 August 1967. She went on to serve as a Government whip in the House of Lords between 1969 and 1970, and as Opposition Deputy Chief Whip from 1972. In 1973 she was elected Chief Whip, becoming the first woman to take charge of a whip's office in either house. On the return of the Labour Party to government in 1974 she became Captain of the Gentlemen-at-Arms (Government Chief Whip). In 1975, she became a Privy Counsellor. From 1979 to 1982 she was once again Opposition Chief Whip. From 1982 to 1987, she was Principal Deputy Chairman of Committees in the House of Lords, an office carrying with it the role of Chairman of the European Communities Committee.
