Input: Strasbourg
As one of the earliest centers of book-printing in Europe (see above: History), Strasbourg for a long time held a large number of incunabula—documents printed before 1500—in her library as one of her most precious heritages. After the total destruction of this institution in 1870, however, a new collection had to be reassembled from scratch. Today, Strasbourg's different public and institutional libraries again display a sizable total number of incunabula, distributed as follows: Bibliothèque nationale et universitaire, ca. 2 098 Médiathèque de la ville et de la communauté urbaine de Strasbourg, 394 Bibliothèque du Grand Séminaire, 238 Médiathèque protestante, 94 and Bibliothèque alsatique du Crédit Mutuel, 5.

What are incunabula's? 
Output: documents printed before 1500


Input: Article: To aid customers with defective consoles, Microsoft extended the Xbox 360's manufacturer's warranty to three years for hardware failure problems that generate a "General Hardware Failure" error report. A "General Hardware Failure" is recognized on all models released before the Xbox 360 S by three quadrants of the ring around the power button flashing red. This error is often known as the "Red Ring of Death". In April 2009 the warranty was extended to also cover failures related to the E74 error code. The warranty extension is not granted for any other types of failures that do not generate these specific error codes.

Now answer this question: How did Microsoft react to general hardware error problems?

Output: Microsoft extended the Xbox 360's manufacturer's warranty to three years


Article: Animal tissue consists of elements and compounds ingested, digested, absorbed, and circulated through the bloodstream to feed the cells of the body. Except in the unborn fetus, the digestive system is the first system involved[vague]. Digestive juices break chemical bonds in ingested molecules, and modify their conformations and energy states. Though some molecules are absorbed into the bloodstream unchanged, digestive processes release them from the matrix of foods. Unabsorbed matter, along with some waste products of metabolism, is eliminated from the body in the feces.

Question: In which specific circumstance is the digestive system not the first system involved in nutrient processing?
Ans: unborn fetus


Here is a question about this article: An antenna (plural antennae or antennas), or aerial, is an electrical device which converts electric power into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter supplies an electric current oscillating at radio frequency (i.e. a high frequency alternating current (AC)) to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage at its terminals, that is applied to a receiver to be amplified.
What is the answer to this question: What device is often used in conjuntion with the antenna?
****
So... radio transmitter or radio receiver


Article: In the 16th century political and religious changes altered the attitude of historians towards John. Tudor historians were generally favourably inclined towards the king, focusing on John's opposition to the Papacy and his promotion of the special rights and prerogatives of a king. Revisionist histories written by John Foxe, William Tyndale and Robert Barnes portrayed John as an early Protestant hero, and John Foxe included the king in his Book of Martyrs. John Speed's Historie of Great Britaine in 1632 praised John's "great renown" as a king; he blamed the bias of medieval chroniclers for the king's poor reputation.

Question: Which historians were favourably inclined towards the king?
Ans:
Tudor historians
