Problem: The Bithynians were a Thracian people living in northwest Anatolia. After Alexander's conquests the region of Bithynia came under the rule of the native king Bas, who defeated Calas, a general of Alexander the Great, and maintained the independence of Bithynia. His son, Zipoetes I of Bithynia maintained this autonomy against Lysimachus and Seleucus I, and assumed the title of king (basileus) in 297 BCE. His son and successor, Nicomedes I, founded Nicomedia, which soon rose to great prosperity, and during his long reign (c. 278 c. 255 BCE), as well as those of his successors, the kingdom of Bithynia held a considerable place among the minor monarchies of Anatolia. Nicomedes also invited the Celtic Galatians into Anatolia as mercenaries, and they later turned on his son Prusias I, who defeated them in battle. Their last king, Nicomedes IV, was unable to maintain himself against Mithridates VI of Pontus, and, after being restored to his throne by the Roman Senate, he bequeathed his kingdom by will to the Roman republic (74 BCE).
When did Zipoetes I assume the role of king?
The answer is the following: 297 BCE

On the shores of the strait, in 1701, the French officer Antoine de la Mothe Cadillac, along with fifty-one French people and French Canadians, founded a settlement called Fort Pontchartrain du Detroit, naming it after Louis Phelypeaux, comte de Pontchartrain, Minister of Marine under Louis XIV. France offered free land to colonists to attract families to Detroit; when it reached a total population of 800 in 1765, it was the largest city between Montreal and New Orleans, both also French settlements. By 1773, the population of Detroit was 1,400. By 1778, its population was up to 2,144 and it was the third-largest city in the Province of Quebec.
What was Detroit's population in 1765?
800

Input: Franco-Prussian War
The Battle of Worth (also known as Froschwiller or Reichshoffen) began when the two armies clashed again on 6 August near Worth in the town of Froschwiller, about 10 miles (16 km) from Wissembourg. The Crown Prince of Prussia's 3rd army had, on the quick reaction of his Chief of Staff General von Blumenthal, drawn reinforcements which brought its strength up to 140,000 troops. The French had been slowly reinforced and their force numbered only 35,000. Although badly outnumbered, the French defended their position just outside Froschwiller. By afternoon, the Germans had suffered c.10,500 killed or wounded and the French had lost a similar number of casualties and another c.9,200 men taken prisoner, a loss of about 50%. The Germans captured Froschwiller which sat on a hilltop in the centre of the French line. Having lost any hope for victory and facing a massacre, the French army disengaged and retreated in a westerly direction towards Bitche and Saverne, hoping to join French forces on the other side of the Vosges mountains. The German 3rd army did not pursue the French but remained in Alsace and moved slowly south, attacking and destroying the French garrisons in the vicinity.

What battle began when two armies collided in the town of Froschwiller?
Output: The Battle of Worth

Input: Article: Czech, the official language of the Czech Republic (a member of the European Union since 2004), is one of the EU's official languages and the 2012 Eurobarometer survey found that Czech was the foreign language most often used in Slovakia. Economist Jonathan van Parys collected data on language knowledge in Europe for the 2012 European Day of Languages. The five countries with the greatest use of Czech were the Czech Republic (98.77 percent), Slovakia (24.86 percent), Portugal (1.93 percent), Poland (0.98 percent) and Germany (0.47 percent).

Now answer this question: Of the five countries with the greatest use of Czech, which country had the lowest percent of use?

Output: Germany

Article: Laurisilva is a unique type of subtropical rainforest found in few areas of Europe and the world: in the Azores, and in particular on the island of Madeira, there are large forests of endemic Laurisilva forests (the latter protected as a natural heritage preserve). There are several species of diverse mammalian fauna, including the fox, badger, iberian lynx, iberian wolf, wild goat (Capra pyrenaica), wild cat (Felis silvestris), hare, weasel, polecat, chameleon, mongoose, civet, brown bear[citation needed] (spotted near Rio Minho, close to Peneda-Geres) and many others. Portugal is an important stopover for migratory birds, in places such as Cape St. Vincent or the Monchique mountains, where thousands of birds cross from Europe to Africa during the autumn or in the spring (return migration).

Question: What type of animal crosses between Europe and Africa during the Autumn?
Ans: migratory birds

Input: Capacitor
Electrolytic capacitors use an aluminum or tantalum plate with an oxide dielectric layer. The second electrode is a liquid electrolyte, connected to the circuit by another foil plate. Electrolytic capacitors offer very high capacitance but suffer from poor tolerances, high instability, gradual loss of capacitance especially when subjected to heat, and high leakage current. Poor quality capacitors may leak electrolyte, which is harmful to printed circuit boards. The conductivity of the electrolyte drops at low temperatures, which increases equivalent series resistance. While widely used for power-supply conditioning, poor high-frequency characteristics make them unsuitable for many applications. Electrolytic capacitors will self-degrade if unused for a period (around a year), and when full power is applied may short circuit, permanently damaging the capacitor and usually blowing a fuse or causing failure of rectifier diodes (for instance, in older equipment, arcing in rectifier tubes). They can be restored before use (and damage) by gradually applying the operating voltage, often done on antique vacuum tube equipment over a period of 30 minutes by using a variable transformer to supply AC power. Unfortunately, the use of this technique may be less satisfactory for some solid state equipment, which may be damaged by operation below its normal power range, requiring that the power supply first be isolated from the consuming circuits. Such remedies may not be applicable to modern high-frequency power supplies as these produce full output voltage even with reduced input.

What type of dielectric layer is used in electrolytic capacitors?
Output:
an oxide dielectric layer
