Problem: Eton College has links with some private schools in India today, maintained from the days of the British Raj, such as The Doon School and Mayo College. Eton College is also a member of the G20 Schools Group, a collection of college preparatory boarding schools from around the world, including Turkey's Robert College, the United States' Phillips Academy and Phillips Exeter Academy, Australia's Scotch College, Melbourne Grammar School and Launceston Church Grammar School, Singapore's Raffles Institution, and Switzerland's International School of Geneva. Eton has recently fostered[when?] a relationship with the Roxbury Latin School, a traditional all-boys private school in Boston, USA. Former Eton headmaster and provost Sir Eric Anderson shares a close friendship with Roxbury Latin Headmaster emeritus F. Washington Jarvis; Anderson has visited Roxbury Latin on numerous occasions, while Jarvis briefly taught theology at Eton after retiring from his headmaster post at Roxbury Latin. The headmasters' close friendship spawned the Hennessy Scholarship, an annual prize established in 2005 and awarded to a graduating RL senior for a year of study at Eton. Hennessy Scholars generally reside in Wotton house.
In what year was the G20 Schools Group established?

Problem: Hellenistic warfare was a continuation of the military developments of Iphicrates and Philip II of Macedon, particularly his use of the Macedonian Phalanx, a dense formation of pikemen, in conjunction with heavy companion cavalry. Armies of the Hellenistic period differed from those of the classical period in being largely made up of professional soldiers and also in their greater specialization and technical proficiency in siege warfare. Hellenistic armies were significantly larger than those of classical Greece relying increasingly on Greek mercenaries (misthophoroi; men-for-pay) and also on non-Greek soldiery such as Thracians, Galatians, Egyptians and Iranians. Some ethnic groups were known for their martial skill in a particular mode of combat and were highly sought after, including Tarantine cavalry, Cretan archers, Rhodian slingers and Thracian peltasts. This period also saw the adoption of new weapons and troop types such as Thureophoroi and the Thorakitai who used the oval Thureos shield and fought with javelins and the machaira sword. The use of heavily armored cataphracts and also horse archers was adopted by the Seleucids, Greco-Bactrians, Armenians and Pontus. The use of war elephants also became common. Seleucus received Indian war elephants from the Mauryan empire, and used them to good effect at the battle of Ipsus. He kept a core of 500 of them at Apameia. The Ptolemies used the smaller African elephant.
Philip II used a dense military formation called what?

Answer: Macedonian Phalanx


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.
Whose light emits more light as they age?
