Context and question: According to the apocryphal Gospel of James, Mary was the daughter of Saint Joachim and Saint Anne. Before Mary's conception, Anne had been barren and was far advanced in years. Mary was given to service as a consecrated virgin in the Temple in Jerusalem when she was three years old, much like Hannah took Samuel to the Tabernacle as recorded in the Old Testament. Some apocryphal accounts state that at the time of her betrothal to Joseph, Mary was 1214 years old, and he was thirty years old, but such accounts are unreliable.
How old was Mary when she was consecrated as a virgin?
Answer: three years old
Context and question: The first high-brightness blue LED was demonstrated by Shuji Nakamura of Nichia Corporation in 1994 and was based on InGaN. In parallel, Isamu Akasaki and Hiroshi Amano in Nagoya were working on developing the important GaN nucleation on sapphire substrates and the demonstration of p-type doping of GaN. Nakamura, Akasaki and Amano were awarded the 2014 Nobel prize in physics for their work. In 1995, Alberto Barbieri at the Cardiff University Laboratory (GB) investigated the efficiency and reliability of high-brightness LEDs and demonstrated a "transparent contact" LED using indium tin oxide (ITO) on (AlGaInP/GaAs).
What did Nakamura, Akasaki, and Amano receive for their study?
Answer: unanswerable
Context and question: Beside the introduction of the lute to Spain (Andalusia) by the Moors, another important point of transfer of the lute from Arabian to European culture was Sicily, where it was brought either by Byzantine or later by Muslim musicians. There were singer-lutenists at the court in Palermo following the Norman conquest of the island from the Muslims, and the lute is depicted extensively in the ceiling paintings in the Palermo's royal Cappella Palatina, dedicated by the Norman King Roger II of Sicily in 1140. His Hohenstaufen grandson Frederick II, Holy Roman Emperor (1194 - 1250) continued integrating Muslims into his court, including Moorish musicians. By the 14th century, lutes had disseminated throughout Italy and, probably because of the cultural influence of the Hohenstaufen kings and emperor, based in Palermo, the lute had also made significant inroads into the German-speaking lands.
What building has ceeiling painting dedicated to the lutenists?
Answer:
Palermo's royal Cappella Palatina,
