Problem: Federalism:

Some federal constitutions also provide that certain constitutional amendments cannot occur without the unanimous consent of all states or of a particular state. The US constitution provides that no state may be deprived of equal representation in the senate without its consent. In Australia, if a proposed amendment will specifically impact one or more states, then it must be endorsed in the referendum held in each of those states. Any amendment to the Canadian constitution that would modify the role of the monarchy would require unanimous consent of the provinces. The German Basic Law provides that no amendment is admissible at all that would abolish the federal system.

What is the German basic law?
---
A: provides that no amendment is admissible at all that would abolish the federal system.

Problem: Sanskrit:

Many Sanskrit dramas also indicate that the language coexisted with Prakrits, spoken by multilingual speakers with a more extensive education. Sanskrit speakers were almost always multilingual. In the medieval era, Sanskrit continued to be spoken and written, particularly by learned Brahmins for scholarly communication. This was a thin layer of Indian society, but covered a wide geography. Centres like Varanasi, Paithan, Pune and Kanchipuram had a strong presence of teaching and debating institutions, and high classical Sanskrit was maintained until British times.

Who used Sanskrit for common communication?
---
A: unanswerable

Problem: Estonia:

The Parliament of Estonia (Estonian: Riigikogu) or the legislative branch is elected by people for a four-year term by proportional representation. The Estonian political system operates under a framework laid out in the 1992 constitutional document. The Estonian parliament has 101 members and influences the governing of the state primarily by determining the income and the expenses of the state (establishing taxes and adopting the budget). At the same time the parliament has the right to present statements, declarations and appeals to the people of Estonia, ratify and denounce international treaties with other states and international organisations and decide on the Government loans.

How many representatives are in the Estonian parliament?
---
A: 101 members

Problem: The Sun (United Kingdom):

The Sun has been openly antagonistic towards other European nations, particularly the French and Germans. During the 1980s and 1990s, the nationalities were routinely described in copy and headlines as "frogs", "krauts" or "hun". As the paper is opposed to the EU it has referred to foreign leaders who it deemed hostile to the UK in unflattering terms. Former President Jacques Chirac of France, for instance, was branded "le Worm". An unflattering picture of German chancellor Angela Merkel, taken from the rear, bore the headline "I'm Big in the Bumdestag" (17 April 2006).

What names were used by The Sun to characterize the French and Germans?
---
A:
"frogs", "krauts" or "hun"
