Problem: Szlachta:

In 1374 King Louis of Hungary approved the Privilege of Koszyce (Polish: "przywilej koszycki" or "ugoda koszycka") in Košice in order to guarantee the Polish throne for his daughter Jadwiga. He broadened the definition of who was a member of the nobility and exempted the entire class from all but one tax (łanowy, which was limited to 2 grosze from łan (an old measure of land size)). In addition, the King's right to raise taxes was abolished; no new taxes could be raised without the agreement of the nobility. Henceforth, also, district offices (Polish: "urzędy ziemskie") were reserved exclusively for local nobility, as the Privilege of Koszyce forbade the king to grant official posts and major Polish castles to foreign knights. Finally, this privilege obliged the King to pay indemnities to nobles injured or taken captive during a war outside Polish borders.

What could the king do to nobles injured or taken during war?
---
A: King to pay indemnities


Problem: Serbo-Croatian:

The Serbo-Croatian dialects differ not only in the question word they are named after, but also heavily in phonology, accentuation and intonation, case endings and tense system (morphology) and basic vocabulary. In the past, Chakavian and Kajkavian dialects were spoken on a much larger territory, but have been replaced by Štokavian during the period of migrations caused by Ottoman Turkish conquest of the Balkans in the 15th and the 16th centuries. These migrations caused the koinéisation of the Shtokavian dialects, that used to form the West Shtokavian (more closer and transitional towards the neighbouring Chakavian and Kajkavian dialects) and East Shtokavian (transitional towards the Torlakian and the whole Bulgaro-Macedonian area) dialect bundles, and their subsequent spread at the expense of Chakavian and Kajkavian. As a result, Štokavian now covers an area larger than all the other dialects combined, and continues to make its progress in the enclaves where non-literary dialects are still being spoken.

Which dialect covers more area than all other dialects combined?
---
A: Štokavian


Problem: Roman Republic:

Tiberius Gracchus was elected tribune in 133 BC. He attempted to enact a law which would have limited the amount of land that any individual could own. The aristocrats, who stood to lose an enormous amount of money, were bitterly opposed to this proposal. Tiberius submitted this law to the Plebeian Council, but the law was vetoed by a tribune named Marcus Octavius. Tiberius then used the Plebeian Council to impeach Octavius. The theory, that a representative of the people ceases to be one when he acts against the wishes of the people, was counter to Roman constitutional theory. If carried to its logical end, this theory would remove all constitutional restraints on the popular will, and put the state under the absolute control of a temporary popular majority. His law was enacted, but Tiberius was murdered with 300 of his associates when he stood for reelection to the tribunate.

When was Tiberius Gracchus murdered?
---
A: when he stood for reelection to the tribunate


Problem: Glass:

In the 20th century, new types of glass such as laminated glass, reinforced glass and glass bricks have increased the use of glass as a building material and resulted in new applications of glass. Multi-storey buildings are frequently constructed with curtain walls made almost entirely of glass. Similarly, laminated glass has been widely applied to vehicles for windscreens. While glass containers have always been used for storage and are valued for their hygienic properties, glass has been utilized increasingly in industry. Optical glass for spectacles has been used since the late Middle Ages. The production of lenses has become increasingly proficient, aiding astronomers as well as having other application in medicine and science. Glass is also employed as the aperture cover in many solar energy systems.

Walls used for storage are often made of what material?
---
A:
unanswerable
