Problem: Gramophone record:

Stereophonic sound recording, which attempts to provide a more natural listening experience by reproducing the spatial locations of sound sources in the horizontal plane, was the natural extension to monophonic recording, and attracted various alternative engineering attempts. The ultimately dominant "45/45" stereophonic record system was invented by Alan Blumlein of EMI in 1931 and patented the same year. EMI cut the first stereo test discs using the system in 1933 (see Bell Labs Stereo Experiments of 1933) although the system was not exploited commercially until much later.

How was the commercial success of stereo sound in the 1930s?
---
A: was not exploited commercially until much later.

Problem: Seven Years%27 War:

The Saxon and Austrian armies were unprepared, and their forces were scattered. Frederick occupied Dresden with little or no opposition from the Saxons. At the Battle of Lobositz on 1 October 1756, Frederick prevented the isolated Saxon army from being reinforced by an Austrian army under General Browne. The Prussians then occupied Saxony; after the Siege of Pirna, the Saxon army surrendered in October 1756, and was forcibly incorporated into the Prussian army. The attack on neutral Saxony caused outrage across Europe and led to the strengthening of the anti-Prussian coalition. The only significant Austrian success was the partial occupation of Silesia. Far from being easy, Frederick's early successes proved indecisive and very costly for Prussia's smaller army. This led him to remark that he did not fight the same Austrians as he had during the previous war.

What was the result of the fury of Europe?
---
A: led to the strengthening of the anti-Prussian coalition

Problem: British Isles:

The Council does not have executive powers but meets biannually to discuss issues of mutual importance. Similarly, the Parliamentary Assembly has no legislative powers but investigates and collects witness evidence from the public on matters of mutual concern to its members. Reports on its findings are presented to the Governments of Ireland and the United Kingdom. During the February 2008 meeting of the BritishIrish Council, it was agreed to set up a standing secretariat that would serve as a permanent 'civil service' for the Council. Leading on from developments in the BritishIrish Council, the chair of the BritishIrish Inter-Parliamentary Assembly, Niall Blaney, has suggested that the body should shadow the BritishIrish Council's work.

The council has executive powers and meets how often?
---
A: unanswerable

Problem: Green:

In the subtractive color system, used in painting and color printing, green is created by a combination of yellow and blue, or yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. On the HSV color wheel, also known as the RGB color wheel, the complement of green is magenta; that is, a color corresponding to an equal mixture of red and blue light (one of the purples). On a traditional color wheel, based on subtractive color, the complementary color to green is considered to be red.

What is the complementary color to blue?

A:
unanswerable
