Problem: Beer:

Drinking chilled beer began with the development of artificial refrigeration and by the 1870s, was spread in those countries that concentrated on brewing pale lager. Chilling beer makes it more refreshing, though below 15.5 °C the chilling starts to reduce taste awareness and reduces it significantly below 10 °C (50 °F). Beer served unchilled—either cool or at room temperature, reveal more of their flavours. Cask Marque, a non-profit UK beer organisation, has set a temperature standard range of 12°–14 °C (53°–57 °F) for cask ales to be served.

When is a beer at its most flavorful?
---
A: unchilled


Problem: The symbol $, usually written before the numerical amount, is used for the U.S. dollar (as well as for many other currencies). The sign was the result of a late 18th-century evolution of the scribal abbreviation "ps" for the peso, the common name for the Spanish dollars that were in wide circulation in the New World from the 16th to the 19th centuries. These Spanish pesos or dollars were minted in Spanish America, namely in Mexico City, Potosí, Bolivia; and Lima, Peru. The p and the s eventually came to be written over each other giving rise to $.
What was the common name for the Spanish dollar?

Answer: peso


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Crimean War was a military conflict fought between October 1853 – March 1856 in which Russia lost to an alliance of France, the United Kingdom, the Ottoman Empire, and Sardinia. The immediate cause involved the rights of Christian minorities in the Holy Land, which was controlled by the Ottoman Empire. The French promoted the rights of Catholics, while Russia promoted those of the Eastern Orthodox Christians. The longer-term causes involved the decline of the Ottoman Empire and the unwillingness of the United Kingdom and France to allow Russia to gain territory and power at Ottoman expense. It has widely been noted that the causes, in one case involving an argument over a key, have never revealed a "greater confusion of purpose", yet led to a war noted for its "notoriously incompetent international butchery."
What year did the Crimean War begin?
A: 1853


Context and question: Task Manager has been redesigned, including a new processes tab with the option to display fewer or more details of running applications and background processes, a heat map using different colors indicating the level of resource usage, network and disk counters, grouping by process type (e.g. applications, background processes and Windows processes), friendly names for processes and a new option which allows users to search the web to find information about obscure processes. Additionally, the Blue Screen of Death has been updated with a simpler and modern design with less technical information displayed.
What is the point of using different colors on a heat map?
Answer: indicating the level of resource usage


Question: Neptune is not visible to the unaided eye and is the only planet in the Solar System found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently observed with a telescope on 23 September 1846 by Johann Galle within a degree of the position predicted by Urbain Le Verrier. Its largest moon, Triton, was discovered shortly thereafter, though none of the planet's remaining known 14 moons were located telescopically until the 20th century. The planet's distance from Earth gives it a very small apparent size, making it challenging to study with Earth-based telescopes. Neptune was visited by Voyager 2, when it flew by the planet on 25 August 1989. The advent of Hubble Space Telescope and large ground-based telescopes with adaptive optics has recently allowed for additional detailed observations from afar.
Is there an answer to this question:  Who didn't discover Neptune?

Answer: unanswerable


Question: Launched worldwide across 2005–2006, the Xbox 360 was initially in short supply in many regions, including North America and Europe. The earliest versions of the console suffered from a high failure rate, indicated by the so-called "Red Ring of Death", necessitating an extension of the device's warranty period. Microsoft released two redesigned models of the console: the Xbox 360 S in 2010, and the Xbox 360 E in 2013. As of June 2014, 84 million Xbox 360 consoles have been sold worldwide, making it the sixth-highest-selling video game console in history, and the highest-selling console made by an American company. Although not the best-selling console of its generation, the Xbox 360 was deemed by TechRadar to be the most influential through its emphasis on digital media distribution and multiplayer gaming on Xbox Live. The Xbox 360's successor, the Xbox One, was released on November 22, 2013. Microsoft has stated they plan to support the Xbox 360 until 2016. The Xbox One is also backwards compatible with the Xbox 360.
Is there an answer to this question: When did the Xbox One launch?

Answer:
November 22, 2013
