Problem: Thuringia:

The landscapes of Thuringia are quite diverse. The far north is occupied by the Harz mountains, followed by the Goldene Aue, a fertile floodplain around Nordhausen with the Helme as most important river. The north-west includes the Eichsfeld, a hilly and sometimes forested region, where the Leine river emanates. The central and northern part of Thuringia is defined by the 3000 km² wide Thuringian Basin, a very fertile and flat area around the Unstrut river and completely surrounded by the following hill chains (clockwise from the north-west): Dün, Hainleite, Windleite, Kyffhäuser, Hohe Schrecke, Schmücke, Finne, Ettersberg, Steigerwald, Thuringian Forest, Hörselberge and Hainich. Within the Basin the smaller hill chains Fahner Höhe and Heilinger Höhen. South of the Thuringian Basin is the Land's largest mountain range, marked by the Thuringian Forest in the north-west, the Thuringian Highland in the middle and the Franconian Forest in the south-east. Most of this range is forested and the Großer Beerberg (983 m) is Thuringia's highest mountain. To the south-west, the Forest is followed up by Werra river valley, dividing it from the Rhön Mountains in the west and the Grabfeld plain in the south. Eastern Thuringia, commonly described as the area east of Saale and Loquitz valley, is marked by a hilly landscape, rising slowly from the flat north to the mountainous south. The Saale in the west and the Weiße Elster in the east are the two big rivers running from south to north and forming densely settled valleys in this area. Between them lies the flat and forested Holzland in the north, the flat and fertile Orlasenke in the middle and the Vogtland, a hilly but in most parts non-forested region in the south. The far eastern region (east of Weiße Elster) is the Osterland or Altenburger Land along Pleiße river, a flat, fertile and densely settled agricultural area.

How many big rivers flow through Thuringia? 
---
A: The Saale in the west and the Weiße Elster in the east


Problem: Many people gain a sense of positive self-esteem from their identity groups, which furthers a sense of community and belonging. Another issue that researchers have attempted to address is the question of why people engage in discrimination, i.e., why they tend to favor those they consider a part of their "in-group" over those considered to be outsiders. Both questions have been given extensive attention by researchers working in the social identity tradition. For example, in work relating to social identity theory it has been shown that merely crafting cognitive distinction between in- and out-groups can lead to subtle effects on people's evaluations of others (Cote & Levine 2002).
People favoring those in their group over outsiders, is an example of what?
---
Answer: discrimination


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Guinea-Bissau has started to show some economic advances after a pact of stability was signed by the main political parties of the country, leading to an IMF-backed structural reform program. The key challenges for the country in the period ahead are to achieve fiscal discipline, rebuild public administration, improve the economic climate for private investment, and promote economic diversification. After the country became independent from Portugal in 1974 due to the Portuguese Colonial War and the Carnation Revolution, the rapid exodus of the Portuguese civilian, military, and political authorities resulted in considerable damage to the country's economic infrastructure, social order, and standard of living.
What country left Guinea-Bissau in 1974?
A: Portugal

Question: The event was significant not only for Yugoslavia and Tito, but also for the global development of socialism, since it was the first major split between Communist states, casting doubt on Comintern's claims for socialism to be a unified force that would eventually control the whole world, as Tito became the first (and the only successful) socialist leader to defy Stalin's leadership in the COMINFORM. This rift with the Soviet Union brought Tito much international recognition, but also triggered a period of instability often referred to as the Informbiro period. Tito's form of communism was labeled "Titoism" by Moscow, which encouraged purges against suspected "Titoites'" throughout the Eastern bloc.
Is there an answer to this question: Throughout what area did purges of Titoites occur?

Answer: Eastern bloc


QUES: Since 1972, International Telecommunication Union's radio telecommunications sector (ITU-R) had been working on creating a global recommendation for Analog HDTV. These recommendations, however, did not fit in the broadcasting bands which could reach home users. The standardization of MPEG-1 in 1993 also led to the acceptance of recommendations ITU-R BT.709. In anticipation of these standards the Digital Video Broadcasting (DVB) organisation was formed, an alliance of broadcasters, consumer electronics manufacturers and regulatory bodies. The DVB develops and agrees upon specifications which are formally standardised by ETSI.

Who standardizes HDTV specifications?
What is the answer?
ANS:
ETSI
