question:
The mosaic pavement of the Vrina Plain basilica of Butrint, Albania appear to pre-date that of the Baptistery by almost a generation, dating to the last quarter of the 5th or the first years of the 6th century. The mosaic displays a variety of motifs including sea-creatures, birds, terrestrial beasts, fruits, flowers, trees and abstracts – designed to depict a terrestrial paradise of God’s creation. Superimposed on this scheme are two large tablets, tabulae ansatae, carrying inscriptions. A variety of fish, a crab, a lobster, shrimps, mushrooms, flowers, a stag and two cruciform designs surround the smaller of the two inscriptions, which reads: In fulfilment of the vow (prayer) of those whose names God knows. This anonymous dedicatory inscription is a public demonstration of the benefactors’ humility and an acknowledgement of God’s omniscience.
answer:
The floor mosaic in Butrint is how much older than that of the Baptistry?


question:
Tower Control controls aircraft on the runway and in the controlled airspace immediately surrounding the airport. Tower controllers may use radar to locate an aircraft's position in three-dimensional space, or they may rely on pilot position reports and visual observation. They coordinate the sequencing of aircraft in the traffic pattern and direct aircraft on how to safely join and leave the circuit. Aircraft which are only passing through the airspace must also contact Tower Control in order to be sure that they remain clear of other traffic.
answer:
Who controls aircraft on the runway?


question:
Hinkley Point C nuclear power station is a project to construct a 3,200 MW two reactor nuclear power station. On 18 October 2010, the British government announced that Hinkley Point – already the site of the disused Hinkley Point A and the still operational Hinkley Point B power stations – was one of the eight sites it considered suitable for future nuclear power stations. NNB Generation Company, a subsidiary of EDF, submitted an application for development consent to the Infrastructure Planning Commission on 31 October 2011. A protest group, Stop Hinkley, was formed to campaign for the closure of Hinkley Point B and oppose any expansion at the Hinkley Point site. In December 2013, the European Commission opened an investigation to assess whether the project breaks state-aid rules. On 8 October 2014 it was announced that the European Commission has approved the project, with an overwhelming majority and only four commissioners voting against the decision.
answer:
What is Hinkley point C
