Problem: Mosaic:

There are very few existing mosaics from the Komnenian period but this paucity must be due to accidents of survival and gives a misleading impression. The only surviving 12th-century mosaic work in Constantinople is a panel in Hagia Sophia depicting Emperor John II and Empress Eirene with the Theotokos (1122–34). The empress with her long braided hair and rosy cheeks is especially capturing. It must be a lifelike portrayal because Eirene was really a redhead as her original Hungarian name, Piroska shows. The adjacent portrait of Emperor Alexios I Komnenos on a pier (from 1122) is similarly personal. The imperial mausoleum of the Komnenos dynasty, the Pantokrator Monastery was certainly decorated with great mosaics but these were later destroyed. The lack of Komnenian mosaics outside the capital is even more apparent. There is only a "Communion of the Apostles" in the apse of the cathedral of Serres.

Where is the only existing 12th century mosaic in Constantinople?

A: Hagia Sophia


Problem: In response to the September 11 attacks, and as part of the Global War on Terror, U.S. and NATO forces invaded Afghanistan in October 2001, displacing the Taliban government. The U.S. Army also led the combined U.S. and allied invasion of Iraq in 2003. It served as the primary source for ground forces with its ability to sustain short and long-term deployment operations. In the following years the mission changed from conflict between regular militaries to counterinsurgency, resulting in the deaths of more than 4,000 U.S service members (as of March 2008) and injuries to thousands more. 23,813 insurgents were killed in Iraq between 2003–2011.
What year did the  European country invade Iraq?

Egypt also hosts an unknown number of refugees and asylum seekers, estimated to be between 500,000 and 3 million. There are some 70,000 Palestinian refugees, and about 150,000 recently arrived Iraqi refugees, but the number of the largest group, the Sudanese, is contested.[nb 1] The once-vibrant and ancient Greek and Jewish communities in Egypt have almost disappeared, with only a small number remaining in the country, but many Egyptian Jews visit on religious or other occasions and tourism. Several important Jewish archaeological and historical sites are found in Cairo, Alexandria and other cities.
What cities house several important Jewish archaelogical sites?
A: Cairo, Alexandria and other cities


Context and question: Since 1972, International Telecommunication Union's radio telecommunications sector (ITU-R) had been working on creating a global recommendation for Analog HDTV. These recommendations, however, did not fit in the broadcasting bands which could reach home users. The standardization of MPEG-1 in 1993 also led to the acceptance of recommendations ITU-R BT.709. In anticipation of these standards the Digital Video Broadcasting (DVB) organisation was formed, an alliance of broadcasters, consumer electronics manufacturers and regulatory bodies. The DVB develops and agrees upon specifications which are formally standardised by ETSI.
Who standardizes HDTV specifications?
Answer: ETSI
