Problem: Capacitor:

Capacitors may retain a charge long after power is removed from a circuit; this charge can cause dangerous or even potentially fatal shocks or damage connected equipment. For example, even a seemingly innocuous device such as a disposable-camera flash unit, powered by a 1.5 volt AA battery, has a capacitor which may contain over 15 joules of energy and be charged to over 300 volts. This is easily capable of delivering a shock. Service procedures for electronic devices usually include instructions to discharge large or high-voltage capacitors, for instance using a Brinkley stick. Capacitors may also have built-in discharge resistors to dissipate stored energy to a safe level within a few seconds after power is removed. High-voltage capacitors are stored with the terminals shorted, as protection from potentially dangerous voltages due to dielectric absorption or from transient voltages the capacitor may pick up from static charges or passing weather events.

What device can be used to discharge large voltage capacitors?

A: a Brinkley stick

Problem: Asphalt:

Synthetic crude oil, also known as syncrude, is the output from a bitumen upgrader facility used in connection with oil sand production in Canada. Bituminous sands are mined using enormous (100 ton capacity) power shovels and loaded into even larger (400 ton capacity) dump trucks for movement to an upgrading facility. The process used to extract the bitumen from the sand is a hot water process originally developed by Dr. Karl Clark of the University of Alberta during the 1920s. After extraction from the sand, the bitumen is fed into a bitumen upgrader which converts it into a light crude oil equivalent. This synthetic substance is fluid enough to be transferred through conventional oil pipelines and can be fed into conventional oil refineries without any further treatment. By 2015 Canadian bitumen upgraders were producing over 1 million barrels (16010^3 m3) per day of synthetic crude oil, of which 75% was exported to oil refineries in the United States.

Who invented the process for removing bitumen from sands?

A: Dr. Karl Clark

Problem: Seven Years%27 War:

The Treaty of Hubertusburg, between Austria, Prussia, and Saxony, was signed on February 15, 1763, at a hunting lodge between Dresden and Leipzig. Negotiations had started there on December 31, 1762. Frederick, who had considered ceding East Prussia to Russia if Peter III helped him secure Saxony, finally insisted on excluding Russia (in fact, no longer a belligerent) from the negotiations. At the same time, he refused to evacuate Saxony until its elector had renounced any claim to reparation. The Austrians wanted at least to retain Glatz, which they had in fact reconquered, but Frederick would not allow it. The treaty simply restored the status quo of 1748, with Silesia and Glatz reverting to Frederick and Saxony to its own elector. The only concession that Prussia made to Austria was to consent to the election of Archduke Joseph as Holy Roman emperor.

What did Austrian want in the Treaty of Hubertusburg

A: The Austrians wanted at least to retain Glatz

Problem: Premier League:

Stadium attendances are a significant source of regular income for Premier League clubs. For the 200910 season, average attendances across the league clubs were 34,215 for Premier League matches with a total aggregate attendance figure of 13,001,616. This represents an increase of 13,089 from the average attendance of 21,126 recorded in the league's first season (199293). However, during the 199293 season the capacities of most stadiums were reduced as clubs replaced terraces with seats in order to meet the Taylor Report's 199495 deadline for all-seater stadiums. The Premier League's record average attendance of 36,144 was set during the 200708 season. This record was then beaten in the 201314 season recording an average attendance of 36,695 with a total attendance of just under 14 million, the highest average in England's top flight since 1950.

Stadium attendances provide what for the Taylor Report clubs?
