In the late 14th century, in the Grand Duchy of Lithuania, Vytautas the Great reformed the Grand Duchy's army: instead of calling all men to arms, he created forces comprising professional warriorsbajorai ("nobles"; see the cognate "boyar"). As there were not enough nobles, Vytautas trained suitable men, relieving them of labor on the land and of other duties; for their military service to the Grand Duke, they were granted land that was worked by hired men (veldams). The newly formed noble families generally took up, as their family names, the Lithuanian pagan given names of their ennobled ancestors; this was the case with the Gostautai, Radvilos, Astikai, Kesgailos and others. These families were granted their coats of arms under the Union of Horodlo (1413).
What is an example of noble family name?
Gostautai,

1853: There were four main events. 1. In the north the Turks captured the border fort of Saint Nicholas in a surprise night attack (27/28 October). They then pushed about 20000 troops across the Cholok River border. Being outnumbered the Russians abandoned Poti and Redut Kale and drew back to Marani. Both sides remained immobile for the next seven months. 2. In the center the Turks moved north from Ardahan to within cannon-shot of Akhaltsike and awaited reinforcements (13 November). The Russians routed them. The claimed losses were 4000 Turks and 400 Russians. 3. In the south about 30000 Turks slowly moved east to the main Russian concentration at Gyumri or Alexandropol (November). They crossed the border and set up artillery south of town. Prince Orbeliani tried to drive them off and found himself trapped. The Turks failed to press their advantage, the remaining Russians rescued Orbeliani and the Turks retired west. Orbeliani lost about 1000 men out of 5000. The Russians now decided to advance, the Turks took up a strong position on the Kars road and attacked. They were defeated in the battle of Basgedikler, losing 6000 men, half their artillery and all their supply train. The Russians lost 1300, including Prince Orbeliani. This was Prince Ellico Orbeliani whose wife was later kidnaped by Shamyl at Tsinandali. 4. At sea the Turks sent a fleet east which was destroyed by Admiral Nakhimov at Sinope.

How many troops did the Turks have when crossing the Cholok River?
Output: 20000 troops

Input: Article: The Gram stain, developed in 1884 by Hans Christian Gram, characterises bacteria based on the structural characteristics of their cell walls. The thick layers of peptidoglycan in the "Gram-positive" cell wall stain purple, while the thin "Gram-negative" cell wall appears pink. By combining morphology and Gram-staining, most bacteria can be classified as belonging to one of four groups (Gram-positive cocci, Gram-positive bacilli, Gram-negative cocci and Gram-negative bacilli). Some organisms are best identified by stains other than the Gram stain, particularly mycobacteria or Nocardia, which show acid-fastness on ZiehlNeelsen or similar stains. Other organisms may need to be identified by their growth in special media, or by other techniques, such as serology.

Now answer this question: What color is typical for Gram-negative bacteria after staining?

Output: pink

Article: Relations between the Rus' and Byzantines became more complex after Oleg took control over Kiev, reflecting commercial, cultural, and military concerns. The wealth and income of the Rus' depended heavily upon trade with Byzantium. Constantine Porphyrogenitus described the annual course of the princes of Kiev, collecting tribute from client tribes, assembling the product into a flotilla of hundreds of boats, conducting them down the Dnieper to the Black Sea, and sailing to the estuary of the Dniester, the Danube delta, and on to Constantinople. On their return trip they would carry silk fabrics, spices, wine, and fruit. The importance of this trade relationship led to military action when disputes arose. The Primary Chronicle reports that the Rus' attacked Constantinople again in 907, probably to secure trade access. The Chronicle glorifies the military prowess and shrewdness of Oleg, an account imbued with legendary detail. Byzantine sources do not mention the attack, but a pair of treaties in 907 and 911 set forth a trade agreement with the Rus', the terms suggesting pressure on the Byzantines, who granted the Rus' quarters and supplies for their merchants and tax-free trading privileges in Constantinople.

Question: When did the Rus attack the Constantinole once again?
Ans: 907

Here is a question about this article: Modern font technology provides a means to address the practical issue of needing to depict a unified Han character in terms of a collection of alternative glyph representations, in the form of Unicode variation sequences. For example, the Advanced Typographic tables of OpenType permit one of a number of alternative glyph representations to be selected when performing the character to glyph mapping process. In this case, information can be provided within plain text to designate which alternate character form to select.
What is the answer to this question: Where is information provided to designate which character form to select?
****
So... plain text
