Problem: The geography of Southampton is influenced by the sea and rivers. The city lies at the northern tip of the Southampton Water, a deep water estuary, which is a ria formed at the end of the last Ice Age. Here, the rivers Test and Itchen converge. The Test—which has salt marsh that makes it ideal for salmon fishing—runs along the western edge of the city, while the Itchen splits Southampton in two—east and west. The city centre is located between the two rivers.
Which river splits the city of Southampton into an east section and a west section?
---
Answer: Itchen


Problem: In the 20th century, Russian was mandatorily taught in the schools of the members of the old Warsaw Pact and in other countries that used to be satellites of the USSR. In particular, these countries include Poland, Bulgaria, the Czech Republic, Slovakia, Hungary, Albania, former East Germany and Cuba. However, younger generations are usually not fluent in it, because Russian is no longer mandatory in the school system. According to the Eurobarometer 2005 survey, though, fluency in Russian remains fairly high (20–40%) in some countries, in particular those where the people speak a Slavic language and thereby have an edge in learning Russian (namely, Poland, Czech Republic, Slovakia, and Bulgaria).
What pact was formed by Cuba?

Answer: unanswerable


Problem: One of the earliest sexual orientation classification schemes was proposed in the 1860s by Karl Heinrich Ulrichs in a series of pamphlets he published privately. The classification scheme, which was meant only to describe males, separated them into three basic categories: dionings, urnings and uranodionings. An urning can be further categorized by degree of effeminacy. These categories directly correspond with the categories of sexual orientation used today: heterosexual, homosexual, and bisexual. In the series of pamphlets, Ulrichs outlined a set of questions to determine if a man was an urning. The definitions of each category of Ulrichs' classification scheme are as follows:
When did Karl Heinrich Ulrichs develop this classification scheme?
