Problem: United States Army:

After the war, though, the Continental Army was quickly given land certificates and disbanded in a reflection of the republican distrust of standing armies. State militias became the new nation's sole ground army, with the exception of a regiment to guard the Western Frontier and one battery of artillery guarding West Point's arsenal. However, because of continuing conflict with Native Americans, it was soon realized that it was necessary to field a trained standing army. The Regular Army was at first very small, and after General St. Clair's defeat at the Battle of the Wabash, the Regular Army was reorganized as the Legion of the United States, which was established in 1791 and renamed the "United States Army" in 1796.

Who was killed at the Battle of the Wabash?

Problem: Richmond, Virginia:

Richmond has a humid subtropical climate (Köppen Cfa), with hot and humid summers and generally cool winters. The mountains to the west act as a partial barrier to outbreaks of cold, continental air in winter; Arctic air is delayed long enough to be modified, then further warmed as it subsides in its approach to Richmond. The open waters of the Chesapeake Bay and Atlantic Ocean contribute to the humid summers and mild winters. The coldest weather normally occurs from late December to early February, and the January daily mean temperature is 37.9 °F (3.3 °C), with an average of 6.0 days with highs at or below the freezing mark. Downtown areas straddle the border between USDA Hardiness zones 7B and 8A, and temperatures seldom lower to 0 °F (−18 °C), with the most recent subzero (°F) reading occurring on January 28, 2000, when the temperature reached −1 °F (−18 °C). The July daily mean temperature is 79.3 °F (26.3 °C), and high temperatures reach or exceed 90 °F (32 °C) approximately 43 days out of the year; while 100 °F (38 °C) temperatures are not uncommon, they do not occur every year. Extremes in temperature have ranged from −12 °F (−24 °C) on January 19, 1940 up to 107 °F (42 °C) on August 6, 1918.[a]

How could one characterize the winters in Richmond?

A: generally cool


Problem: Incandescent light bulb:

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.

Do incandescent lights emit more, less, or the same amount of light as they age?

A: less


Problem: Gothic architecture:

In France, simultaneously, the towering figure of the Gothic Revival was Eugène Viollet-le-Duc, who outdid historical Gothic constructions to create a Gothic as it ought to have been, notably at the fortified city of Carcassonne in the south of France and in some richly fortified keeps for industrial magnates. Viollet-le-Duc compiled and coordinated an Encyclopédie médiévale that was a rich repertory his contemporaries mined for architectural details. He effected vigorous restoration of crumbling detail of French cathedrals, including the Abbey of Saint-Denis and famously at Notre Dame de Paris, where many of whose most "Gothic" gargoyles are Viollet-le-Duc's. He taught a generation of reform-Gothic designers and showed how to apply Gothic style to modern structural materials, especially cast iron.

What empty city in Northern France did Viollet-le-Duc recreate historical Gothic constructions?
