Problem: Molotov%E2%80%93Ribbentrop Pact:

The Soviets also helped Germany to avoid British naval blockades by providing a submarine base, Basis Nord, in the northern Soviet Union near Murmansk. This also provided a refueling and maintenance location, and a takeoff point for raids and attacks on shipping. In addition, the Soviets provided Germany with access to the Northern Sea Route for both cargo ships and raiders (though only the commerce raider Komet used the route before the German invasion), which forced Britain to protect sea lanes in both the Atlantic and the Pacific.

Where was the sub base located?
---
A: northern Soviet Union near Murmansk

Problem: Since the 2006 FIFA World Cup, the internal and external evaluation of Germany's national image has changed. In the annual Nation Brands Index global survey, Germany became significantly and repeatedly more highly ranked after the tournament. People in 20 different states assessed the country's reputation in terms of culture, politics, exports, its people and its attractiveness to tourists, immigrants and investments. Germany has been named the world's second most valued nation among 50 countries in 2010. Another global opinion poll, for the BBC, revealed that Germany is recognised for the most positive influence in the world in 2010. A majority of 59% have a positive view of the country, while 14% have a negative view.
What index ranked Germany high before the 2006 FIFA World Cup?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Different fields of science use the term matter in different, and sometimes incompatible, ways. Some of these ways are based on loose historical meanings, from a time when there was no reason to distinguish mass and matter. As such, there is no single universally agreed scientific meaning of the word "matter". Scientifically, the term "mass" is well-defined, but "matter" is not. Sometimes in the field of physics "matter" is simply equated with particles that exhibit rest mass (i.e., that cannot travel at the speed of light), such as quarks and leptons. However, in both physics and chemistry, matter exhibits both wave-like and particle-like properties, the so-called waveparticle duality.
What does matter do in chemistry that it does not do in physics?
A: unanswerable

Question: This situation prevailed until 1639, when most of Alsace was conquered by France so as to keep it out of the hands of the Spanish Habsburgs, who wanted a clear road to their valuable and rebellious possessions in the Spanish Netherlands. Beset by enemies and seeking to gain a free hand in Hungary, the Habsburgs sold their Sundgau territory (mostly in Upper Alsace) to France in 1646, which had occupied it, for the sum of 1.2 million Thalers. When hostilities were concluded in 1648 with the Treaty of Westphalia, most of Alsace was recognized as part of France, although some towns remained independent. The treaty stipulations regarding Alsace were complex; although the French king gained sovereignty, existing rights and customs of the inhabitants were largely preserved. France continued to maintain its customs border along the Vosges mountains where it had been, leaving Alsace more economically oriented to neighbouring German-speaking lands. The German language remained in use in local administration, in schools, and at the (Lutheran) University of Strasbourg, which continued to draw students from other German-speaking lands. The 1685 Edict of Fontainebleau, by which the French king ordered the suppression of French Protestantism, was not applied in Alsace. France did endeavour to promote Catholicism; Strasbourg Cathedral, for example, which had been Lutheran from 1524 to 1681, was returned to the Catholic Church. However, compared to the rest of France, Alsace enjoyed a climate of religious tolerance.
Is there an answer to this question: When did the Spanish conquer Alsace?

Answer: unanswerable

Problem: Melbourne:

A long list of AM and FM radio stations broadcast to greater Melbourne. These include "public" (i.e., state-owned ABC and SBS) and community stations. Many commercial stations are networked-owned: DMG has Nova 100 and Smooth; ARN controls Gold 104.3 and KIIS 101.1; and Southern Cross Austereo runs both Fox and Triple M. Stations from towns in regional Victoria may also be heard (e.g. 93.9 Bay FM, Geelong). Youth alternatives include ABC Triple J and youth run SYN. Triple J, and similarly PBS and Triple R, strive to play under represented music. JOY 94.9 caters for gay, lesbian, bisexual and transgender audiences. For fans of classical music there are 3MBS and ABC Classic FM. Light FM is a contemporary Christian station. AM stations include ABC: 774, Radio National, and News Radio; also Fairfax affiliates 3AW (talk) and Magic (easy listening). For sport fans and enthusiasts there is SEN 1116. Melbourne has many community run stations that serve alternative interests, such as 3CR and 3KND (Indigenous). Many suburbs have low powered community run stations serving local audiences.
