Here is a question about this article: With the defeat of Marshal Bazaine's Army of the Rhine at Gravelotte, the French were forced to retire to Metz, where they were besieged by over 150,000 Prussian troops of the First and Second Armies. Napoleon III and MacMahon formed the new French Army of Chalons, to march on to Metz to rescue Bazaine. Napoleon III personally led the army with Marshal MacMahon in attendance. The Army of Chalons marched northeast towards the Belgian border to avoid the Prussians before striking south to link up with Bazaine. The Prussians, under the command of Field Marshal Count Helmuth von Moltke, took advantage of this maneuver to catch the French in a pincer grip. He left the Prussian First and Second Armies besieging Metz, except three corps detached to form the Army of the Meuse under the Crown Prince of Saxony. With this army and the Prussian Third Army, Moltke marched northward and caught up with the French at Beaumont on 30 August. After a sharp fight in which they lost 5,000 men and 40 cannons, the French withdrew toward Sedan. Having reformed in the town, the Army of Chalons was immediately isolated by the converging Prussian armies. Napoleon III ordered the army to break out of the encirclement immediately. With MacMahon wounded on the previous day, General Auguste Ducrot took command of the French troops in the field.
What is the answer to this question: Who formed the new French Army of Chalons?
****
So... Napoleon III and MacMahon

Here is a question about this article: 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 is the answer to this question: Do incandescent lights emit more, less, or the same amount of light as they age?
****
So... less

Here is a question about this article: Hanover was founded in medieval times on the east bank of the River Leine. Its original name Honovere may mean "high (river)bank", though this is debated (cf. das Hohe Ufer). Hanover was a small village of ferrymen and fishermen that became a comparatively large town in the 13th century due to its position at a natural crossroads. As overland travel was relatively difficult, its position on the upper navigable reaches of the river helped it to grow by increasing trade. It was connected to the Hanseatic League city of Bremen by the Leine, and was situated near the southern edge of the wide North German Plain and north-west of the Harz mountains, so that east-west traffic such as mule trains passed through it. Hanover was thus a gateway to the Rhine, Ruhr and Saar river valleys, their industrial areas which grew up to the southwest and the plains regions to the east and north, for overland traffic skirting the Harz between the Low Countries and Saxony or Thuringia.
What is the answer to this question: What did Hanover possibly originally mean?

So...
"high (river)bank"
