Input: Incandescent light bulb
The role of the gas is to prevent evaporation of the filament, without introducing significant heat losses. For these properties, chemical inertness and high atomic or molecular weight is desirable. The presence of gas molecules knocks the liberated tungsten atoms back to the filament, reducing its evaporation and allowing it to be operated at higher temperature without reducing its life (or, for operating at the same temperature, prolongs the filament life). It however introduces heat losses (and therefore efficiency loss) from the filament, by heat conduction and heat convection.

How do gases prevent evaporation of the filament?
Output: The presence of gas molecules knocks the liberated tungsten atoms back to the filament

Input: Seven Years%27 War
By 1763, the war in Central Europe was essentially a stalemate. Frederick had retaken most of Silesia and Saxony but not the latter's capital, Dresden. His financial situation was not dire, but his kingdom was devastated and his army severely weakened. His manpower had dramatically decreased, and he had lost so many effective officers and generals that a new offensive was perhaps impossible. British subsidies had been stopped by the new Prime Minister Lord Bute, and the Russian Emperor had been overthrown by his wife, Catherine, who ended Russia's alliance with Prussia and withdrew from the war. Austria, however, like most participants, was facing a severe financial crisis and had to decrease the size of its army, something which greatly affected its offensive power. Indeed, after having effectively sustained a long war, its administration was in disarray. By that time, it still held Dresden, the southeastern parts of Saxony, the county of Glatz, and southern Silesia, but the prospect of victory was dim without Russian support. In 1763 a peace settlement was reached at the Treaty of Hubertusburg, ending the war in central Europe.

In 1763 what was the status of Frederick?
Output: his kingdom was devastated and his army severely weakened

Input: Bacteria
Most bacteria have a single circular chromosome that can range in size from only 160,000 base pairs in the endosymbiotic bacteria Candidatus Carsonella ruddii, to 12,200,000 base pairs in the soil-dwelling bacteria Sorangium cellulosum. Spirochaetes of the genus Borrelia are a notable exception to this arrangement, with bacteria such as Borrelia burgdorferi, the cause of Lyme disease, containing a single linear chromosome. The genes in bacterial genomes are usually a single continuous stretch of DNA and although several different types of introns do exist in bacteria, these are much rarer than in eukaryotes.

What bacteria is an exception to single circular chromosome rule?
Output: Spirochaetes of the genus Borrelia

Input: American Idol
Contestants go through at least three sets of cuts. The first is a brief audition with a few other contestants in front of selectors which may include one of the show's producers. Although auditions can exceed 10,000 in each city, only a few hundred of these make it past the preliminary round of auditions. Successful contestants then sing in front of producers, where more may be cut. Only then can they proceed to audition in front of the judges, which is the only audition stage shown on television. Those selected by the judges are sent to Hollywood. Between 10–60 people in each city may make it to Hollywood[citation needed].

How many rounds can a contestant make it through before Hollywood?
Output:
three
