Question: Very few early Byzantine mosaics survived the Iconoclastic destruction of the 8th century. Among the rare examples are the 6th-century Christ in majesty (or Ezekiel's Vision) mosaic in the apse of the Church of Hosios David in Thessaloniki that was hidden behind mortar during those dangerous times. Nine mosaic panels in the Hagios Demetrios Church, which were made between 634 and 730, also escaped destruction. Unusually almost all represent Saint Demetrius of Thessaloniki, often with suppliants before him.
Is there an answer to this question: How many Byzantine mosaics survived past the 8th century?

Answer: Very few


Question: In June 1963, Rev. Martin Luther King, Jr. gave a major speech in Detroit that foreshadowed his "I Have a Dream" speech in Washington, D.C. two months later. While the African-American Civil Rights Movement gained significant federal civil rights laws in 1964 and 1965, longstanding inequities resulted in confrontations between the police and inner city black youth wanting change. Longstanding tensions in Detroit culminated in the Twelfth Street riot in July 1967. Governor George W. Romney ordered the Michigan National Guard into Detroit, and President Johnson sent in U.S. Army troops. The result was 43 dead, 467 injured, over 7,200 arrests, and more than 2,000 buildings destroyed, mostly in black residential and business areas. Thousands of small businesses closed permanently or relocated to safer neighborhoods. The affected district lay in ruins for decades. It was the most costly riot in the United States.

Question: The Thuringian population has a significant sex ratio gap, caused by the emigration of young women, especially in rural areas. Overall, there are 115 to 120 men per 100 women in the 25–40 age group ("family founders") which has negative consequences for the birth ratio. Furthermore, the population is getting older and older with some rural municipalities recording more than 30% of over-65s (pensioners). This is a problem for the regional labour market, as there are twice as many people leaving as entering the job market annually.
Is there an answer to this question: How many citizens of Thuringia are dead before the age of 65?

Answer:
unanswerable
