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.
How much energy could a capacitor in a disposable camera contain?
over 15 joules of energy


Input: Houston
Houston (i/ˈhjuːstən/ HYOO-stən) is the most populous city in Texas and the fourth most populous city in the United States, located in Southeast Texas near the Gulf of Mexico. With a census-estimated 2014 population of 2.239 million people, within a land area of 599.6 square miles (1,553 km2), it also is the largest city in the Southern United States, as well as the seat of Harris County. It is the principal city of Houston–The Woodlands–Sugar Land, which is the fifth most populated metropolitan area in the United States.

What is the land are of the City of Houston?
Output: 599.6 square miles


Input: Article: The Tito-Stalin split had large ramifications for countries outside the USSR and Yugoslavia. It has, for example, been given as one of the reasons for the Slánský trial in Czechoslovakia, in which 14 high-level Communist officials were purged, with 11 of them being executed. Stalin put pressure on Czechoslovakia to conduct purges in order to discourage the spread of the idea of a "national path to socialism," which Tito espoused.

Now answer this question: Who espoused the "national path to socialism"?

Output: Tito


Article: The Parliament of Estonia (Estonian: Riigikogu) or the legislative branch is elected by people for a four-year term by proportional representation. The Estonian political system operates under a framework laid out in the 1992 constitutional document. The Estonian parliament has 101 members and influences the governing of the state primarily by determining the income and the expenses of the state (establishing taxes and adopting the budget). At the same time the parliament has the right to present statements, declarations and appeals to the people of Estonia, ratify and denounce international treaties with other states and international organisations and decide on the Government loans.

Question: What can the Estonian parliament do in regards to treaties?
Ans: ratify and denounce international treaties


Here is a question about this article: Despite delays in some countries, the number of European HD channels and viewers has risen steadily since the first HDTV broadcasts, with SES's annual Satellite Monitor market survey for 2010 reporting more than 200 commercial channels broadcasting in HD from Astra satellites, 185 million HD capable TVs sold in Europe (£60 million in 2010 alone), and 20 million households (27% of all European digital satellite TV homes) watching HD satellite broadcasts (16 million via Astra satellites).
What is the answer to this question: According to the 2010 Satellite Monitor market survey, how many HD capable TV's were sold in Europe?
****
So... 185 million


Article: The first amniotes apparently arose in the Late Carboniferous. They descended from earlier reptiliomorph amphibious tetrapods, which lived on land that was already inhabited by insects and other invertebrates as well as by ferns, mosses and other plants. Within a few million years, two important amniote lineages became distinct: the synapsids, which would later include the common ancestor of the mammals; and the sauropsids, which would eventually come to include turtles, lizards, snakes, crocodilians, dinosaurs and birds. Synapsids have a single hole (temporal fenestra) low on each side of the skull.

Question: From which period did the first known amniotes arise from?
Ans:
Carboniferous
