Article: Africa separated from Antarctica in the Jurassic, around 160 Ma, followed by the Indian subcontinent in the early Cretaceous (about 125 Ma). By the end of the Cretaceous, about 66 Ma, Antarctica (then connected to Australia) still had a subtropical climate and flora, complete with a marsupial fauna. In the Eocene epoch, about 40 Ma Australia-New Guinea separated from Antarctica, so that latitudinal currents could isolate Antarctica from Australia, and the first ice began to appear. During the EoceneOligocene extinction event about 34 million years ago, CO2 levels have been found to be about 760 ppm and had been decreasing from earlier levels in the thousands of ppm.

Question: When did Australia separate from Antarctica?
Ans: Eocene epoch

Article: Portugal has considerable resources of wind and river power, the two most cost-effective renewable sources. Since the turn of the 21st century, there has been a trend towards the development of a renewable resource industry and reduction of both consumption and use of fossil fuel resources. In 2006, the world's largest solar power plant at that date, the Moura Photovoltaic Power Station, began operating near Moura, in the south, while the world's first commercial wave power farm, the Agucadoura Wave Farm, opened in the Norte region (2008). By the end of 2006, 66% of the country's electrical production was from coal and fuel power plants, while 29% were derived from hydroelectric dams, and 6% by wind energy.

Question: By the end of 2006, what percentage of Portugal's energy production was from renewable sources?
Ans: 29%

Article: The early settlement was often subject to attack from sea and land, including periodic assaults from Spain and France (both of whom contested England's claims to the region), and pirates. These were combined with raids by Native Americans, who tried to protect themselves from so-called European "settlers," who in turn wanted to expand the settlement. The heart of the city was fortified according to a 1704 plan by Governor Johnson. Except those fronting Cooper River, the walls were largely removed during the 1720s.

Question: Which group raided the settlement as a means to protect themselves from settlers?
Ans: Native Americans

Article: The mosaics of the Church of St Stephen in ancient Kastron Mefaa (now Umm ar-Rasas) were made in 785 (discovered after 1986). The perfectly preserved mosaic floor is the largest one in Jordan. On the central panel hunting and fishing scenes are depicted while another panel illustrates the most important cities of the region. The frame of the mosaic is especially decorative. Six mosaic masters signed the work: Staurachios from Esbus, Euremios, Elias, Constantinus, Germanus and Abdela. It overlays another, damaged, mosaic floor of the earlier (587) "Church of Bishop Sergius." Another four churches were excavated nearby with traces of mosaic decoration.

Question: When were the mosaics in the Church of St Stephen re-discovered?
Ans:
1986
