Input: Translation
When a historic document survives only in translation, the original having been lost, researchers sometimes undertake back-translation in an effort to reconstruct the original text. An example involves the novel The Saragossa Manuscript by the Polish aristocrat Jan Potocki (17611815), who wrote the novel in French and anonymously published fragments in 1804 and 181314. Portions of the original French-language manuscript were subsequently lost; however, the missing fragments survived in a Polish translation that was made by Edmund Chojecki in 1847 from a complete French copy, now lost. French-language versions of the complete Saragossa Manuscript have since been produced, based on extant French-language fragments and on French-language versions that have been back-translated from Chojecki's Polish version.

What language was The Saragossa Manuscript originally written in?
Output: French

Input: Mandolin
At the very end of the 19th century, a new style, with a carved top and back construction inspired by violin family instruments began to supplant the European-style bowl-back instruments in the United States. This new style is credited to mandolins designed and built by Orville Gibson, a Kalamazoo, Michigan luthier who founded the "Gibson Mandolin-Guitar Manufacturing Co., Limited" in 1902. Gibson mandolins evolved into two basic styles: the Florentine or F-style, which has a decorative scroll near the neck, two points on the lower body and usually a scroll carved into the headstock; and the A-style, which is pear shaped, has no points and usually has a simpler headstock.

What was the new sytle of mandolins inspired from?
Output: violin family instruments

Input: Houston
The primary city airport is George Bush Intercontinental Airport (IAH), the tenth-busiest in the United States for total passengers, and twenty eighth-busiest worldwide.

In 2006, the United States Department of Transportation named IAH the fastest-growing of the top ten airports in the United States. The Houston Air Route Traffic Control Center stands on the George Bush Intercontinental Airport grounds.

How does Houston's George Bush Intercontinental Airport rank for number of passengers?
Output: tenth-busiest

Input: Franco-Prussian War
The Prussian Army was composed not of regulars but conscripts. Service was compulsory for all of men of military age, and thus Prussia and its North and South German allies could mobilise and field some 1,000,000 soldiers in time of war. German tactics emphasised encirclement battles like Cannae and using artillery offensively whenever possible. Rather than advancing in a column or line formation, Prussian infantry moved in small groups that were harder to target by artillery or French defensive fire. The sheer number of soldiers available made encirclement en masse and destruction of French formations relatively easy.

German tactics relied on what type of battle strategy?
Output:
encirclement battles
