Article: Muammar Gaddafi was born in a tent near Qasr Abu Hadi, a rural area outside the town of Sirte in the deserts of western Libya. His family came from a small, relatively un-influential tribal group called the Qadhadhfa, who were Arabized Berber in heritage. His father, Mohammad Abdul Salam bin Hamed bin Mohammad, was known as Abu Meniar (died 1985), and his mother was named Aisha (died 1978); Abu Meniar earned a meager subsistence as a goat and camel herder. Nomadic Bedouins, they were illiterate and kept no birth records. As such, Gaddafi's date of birth is not known with certainty, and sources have set it in 1942 or in the spring of 1943, although biographers Blundy and Lycett noted that it could have been pre-1940. His parents' only surviving son, he had three older sisters. Gaddafi's upbringing in Bedouin culture influenced his personal tastes for the rest of his life. He repeatedly expressed a preference for the desert over the city and retreated to the desert to meditate.

Question: How did his upbringing impact his later life preferences?
Ans: He repeatedly expressed a preference for the desert over the city and retreated to the desert to meditate.

Article: Christian mosaic art also flourished in Rome, gradually declining as conditions became more difficult in the Early Middle Ages. 5th century mosaics can be found over the triumphal arch and in the nave of the basilica of Santa Maria Maggiore. The 27 surviving panels of the nave are the most important mosaic cycle in Rome of this period. Two other important 5th century mosaics are lost but we know them from 17th-century drawings. In the apse mosaic of Sant'Agata dei Goti (462472, destroyed in 1589) Christ was seated on a globe with the twelve Apostles flanking him, six on either side. At Sant'Andrea in Catabarbara (468483, destroyed in 1686) Christ appeared in the center, flanked on either side by three Apostles. Four streams flowed from the little mountain supporting Christ. The original 5th-century apse mosaic of the Santa Sabina was replaced by a very similar fresco by Taddeo Zuccari in 1559. The composition probably remained unchanged: Christ flanked by male and female saints, seated on a hill while lambs drinking from a stream at its feet. All three mosaics had a similar iconography.

Question: When was the mosaic at Santa Sabina replaced with a fresco?
Ans: 1559

Article: At the foundation of the Order, the "Medal of the Order of the British Empire" was instituted, to serve as a lower award granting recipients affiliation but not membership. In 1922, this was renamed the "British Empire Medal". It stopped being awarded by the United Kingdom as part of the 1993 reforms to the honours system, but was again awarded beginning in 2012, starting with 293 BEMs awarded for the Queen's Diamond Jubilee. In addition, the BEM is awarded by the Cook Islands and by some other Commonwealth nations. In 2004, a report entitled "A Matter of Honour: Reforming Our Honours System" by a Commons committee recommended to phase out the Order of the British Empire, as its title was "now considered to be unacceptable, being thought to embody values that are no longer shared by many of the country's population".

Question: In what year was the Medal of the Order of the British Empire established?
Ans: 1922

Article: Historically, AC motors were used for single or double speed elevator machines on the grounds of cost and lower usage applications where car speed and passenger comfort were less of an issue, but for higher speed, larger capacity elevators, the need for infinitely variable speed control over the traction machine becomes an issue. Therefore, DC machines powered by an AC/DC motor generator were the preferred solution. The MG set also typically powered the relay controller of the elevator, which has the added advantage of electrically isolating the elevators from the rest of a building's electrical system, thus eliminating the transient power spikes in the building's electrical supply caused by the motors starting and stopping (causing lighting to dim every time the elevators are used for example), as well as interference to other electrical equipment caused by the arcing of the relay contactors in the control system.

Question: What is a known advantage of the MG set?
Ans:
electrically isolating the elevators from the rest of a building's electrical system
