Problem: Possibly as early as the second century AD, Virgil's works were seen as having magical properties and were used for divination. In what became known as the Sortes Vergilianae (Virgilian Lots), passages would be selected at random and interpreted to answer questions. In the 12th century, starting around Naples but eventually spreading widely throughout Europe, a tradition developed in which Virgil was regarded as a great magician. Legends about Virgil and his magical powers remained popular for over two hundred years, arguably becoming as prominent as his writings themselves. Virgil's legacy in medieval Wales was such that the Welsh version of his name, Fferyllt or Pheryllt, became a generic term for magic-worker, and survives in the modern Welsh word for pharmacist, fferyllydd.
Where did the tradition start which regarded Virgil as a great magician?

Answer: Naples

Problem: The initial cost of an incandescent bulb is small compared to the cost of the energy it uses over its lifetime. Incandescent bulbs have a shorter life than most other lighting, an important factor if replacement is inconvenient or expensive. Some types of lamp, including incandescent and fluorescent, emit less light as they age; this may be an inconvenience, or may reduce effective lifetime due to lamp replacement before total failure. A comparison of incandescent lamp operating cost with other light sources must include illumination requirements, cost of the lamp and labor cost to replace lamps (taking into account effective lamp lifetime), cost of electricity used, effect of lamp operation on heating and air conditioning systems. When used for lighting in houses and commercial buildings, the energy lost to heat can significantly increase the energy required by a building's air conditioning system. During the heating season heat produced by the bulbs is not wasted, although in most cases it is more cost effective to obtain heat from the heating system. Regardless, over the course of a year a more efficient lighting system saves energy in nearly all climates.
What type of light has a longer life span than other sources?

Problem: Operation Torch also served as a valuable training ground for Eisenhower's combat command skills; during the initial phase of Generalfeldmarschall Erwin Rommel's move into the Kasserine Pass, Eisenhower created some confusion in the ranks by some interference with the execution of battle plans by his subordinates. He also was initially indecisive in his removal of Lloyd Fredendall, commanding U.S. II Corps. He became more adroit in such matters in later campaigns. In February 1943, his authority was extended as commander of AFHQ across the Mediterranean basin to include the British Eighth Army, commanded by General Sir Bernard Montgomery. The Eighth Army had advanced across the Western Desert from the east and was ready for the start of the Tunisia Campaign. Eisenhower gained his fourth star and gave up command of ETOUSA to become commander of NATOUSA.
When did Eisenhower receive authority over the British Eighth Army?
