Problem: Franco-Prussian War:

On 18 August, the battle began when at 08:00 Moltke ordered the First and Second Armies to advance against the French positions. By 12:00, General Manstein opened up the battle before the village of Amanvillers with artillery from the 25th Infantry Division. But the French had spent the night and early morning digging trenches and rifle pits while placing their artillery and their mitrailleuses in concealed positions. Finally aware of the Prussian advance, the French opened up a massive return fire against the mass of advancing Germans. The battle at first appeared to favor the French with their superior Chassepot rifle. However, the Prussian artillery was superior with the all-steel Krupp breech-loading gun. By 14:30, General Steinmetz, the commander of the First Army, unilaterally launched his VIII Corps across the Mance Ravine in which the Prussian infantry were soon pinned down by murderous rifle and mitrailleuse fire from the French positions. At 15:00, the massed guns of the VII and VIII Corps opened fire to support the attack. But by 16:00, with the attack in danger of stalling, Steinmetz ordered the VII Corps forward, followed by the 1st Cavalry Division.

Problem: Initially the companies affected were those directly involved in home construction and mortgage lending such as Northern Rock and Countrywide Financial, as they could no longer obtain financing through the credit markets. Over 100 mortgage lenders went bankrupt during 2007 and 2008. Concerns that investment bank Bear Stearns would collapse in March 2008 resulted in its fire-sale to JP Morgan Chase. The financial institution crisis hit its peak in September and October 2008. Several major institutions either failed, were acquired under duress, or were subject to government takeover. These included Lehman Brothers, Merrill Lynch, Fannie Mae, Freddie Mac, Washington Mutual, Wachovia, Citigroup, and AIG. On Oct. 6, 2008, three weeks after Lehman Brothers filed the largest bankruptcy in U.S. history, Lehman's former CEO found himself before Representative Henry A. Waxman, the California Democrat who chaired the House Committee on Oversight and Government Reform. Fuld said he was a victim of the collapse, blaming a "crisis of confidence" in the markets for dooming his firm.
When did the financial institution crisis hit its peak?

Answer: September and October 2008

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
To prevent the risk of out-of-phase supplies mixing, sections of line fed from different feeder stations must be kept strictly isolated. This is achieved by Neutral Sections (also known as Phase Breaks), usually provided at feeder stations and midway between them although, typically, only half are in use at any time, the others being provided to allow a feeder station to be shut down and power provided from adjacent feeder stations. Neutral Sections usually consist of an earthed section of wire which is separated from the live wires on either side by insulating material, typically ceramic beads, designed so that the pantograph will smoothly run from one section to the other. The earthed section prevents an arc being drawn from one live section to the other, as the voltage difference may be higher than the normal system voltage if the live sections are on different phases and the protective circuit breakers may not be able to safely interrupt the considerable current that would flow. To prevent the risk of an arc being drawn across from one section of wire to earth, when passing through the neutral section, the train must be coasting and the circuit breakers must be open. In many cases, this is done manually by the drivers. To help them, a warning board is provided just before both the neutral section and an advance warning some distance before. A further board is then provided after the neutral section to tell drivers to re-close the circuit breaker, although drivers must not do this until the rear pantograph has passed this board. In the UK, a system known as Automatic Power Control (APC) automatically opens and closes the circuit breaker, this being achieved by using sets of permanent magnets alongside the track communicating with a detector on the train. The only action needed by the driver is to shut off power and coast and therefore warning boards are still provided at and on the approach to neutral sections.
The earthed section allows for what?
A: unanswerable

Context and question: The halogen lamp reduces uneven evaporation of the filament and eliminates darkening of the envelope by filling the lamp with a halogen gas at low pressure, rather than an inert gas. The halogen cycle increases the lifetime of the bulb and prevents its darkening by redepositing tungsten from the inside of the bulb back onto the filament. The halogen lamp can operate its filament at a higher temperature than a standard gas filled lamp of similar power without loss of operating life. Such bulbs are much smaller than normal incandescent bulbs, and are widely used where intense illumination is needed in a limited space. Fiber-optic lamps for optical microscopy is one typical application.
Does the halogen bulp increase, reduce, or have no effect on filament evaporation?
Answer: reduces

Question: Unicode is developed in conjunction with the International Organization for Standardization and shares the character repertoire with ISO/IEC 10646: the Universal Character Set. Unicode and ISO/IEC 10646 function equivalently as character encodings, but The Unicode Standard contains much more information for implementers, coveringin depthtopics such as bitwise encoding, collation and rendering. The Unicode Standard enumerates a multitude of character properties, including those needed for supporting bidirectional text. The two standards do use slightly different terminology.
Is there an answer to this question: What is developed alongside the UCS?

Answer: unanswerable

QUES: The Super Nintendo Entertainment System (officially abbreviated the Super NES[b] or SNES[c], and commonly shortened to Super Nintendo[d]) is a 16-bit home video game console developed by Nintendo that was released in 1990 in Japan and South Korea, 1991 in North America, 1992 in Europe and Australasia (Oceania), and 1993 in South America. In Japan, the system is called the Super Famicom (Japanese: , Hepburn: Supa Famikon?, officially adopting the abbreviated name of its predecessor, the Family Computer), or SFC for short. In South Korea, it is known as the Super Comboy ( Syupeo Keomboi) and was distributed by Hyundai Electronics. Although each version is essentially the same, several forms of regional lockout prevent the different versions from being compatible with one another. It was released in Brazil on September 2, 1992, by Playtronic.
