Input: Read this: In 2005, Estonia joined the European Union's Nordic Battle Group. It has also shown continued interest in joining the Nordic Council. Whereas in 1992 Russia accounted for 92% of Estonia's international trade, today there is extensive economic interdependence between Estonia and its Nordic neighbours: three quarters of foreign investment in Estonia originates in the Nordic countries (principally Finland and Sweden), to which Estonia sends 42% of its exports (as compared to 6.5% going to Russia, 8.8% to Latvia, and 4.7% to Lithuania). On the other hand, the Estonian political system, its flat rate of income tax, and its non-welfare-state model distinguish it from the Nordic countries and their Nordic model, and indeed from many other European countries.
Question: What percentage of Estonia exports are sent to Nordic countries?

Output: 42%

QUES: The U.S. Constitution provides that Congress shall have the power to "borrow money on the credit of the United States". Congress has exercised that power by authorizing Federal Reserve Banks to issue Federal Reserve Notes. Those notes are "obligations of the United States" and "shall be redeemed in lawful money on demand at the Treasury Department of the United States, in the city of Washington, District of Columbia, or at any Federal Reserve bank". Federal Reserve Notes are designated by law as "legal tender" for the payment of debts. Congress has also authorized the issuance of more than 10 other types of banknotes, including the United States Note and the Federal Reserve Bank Note. The Federal Reserve Note is the only type that remains in circulation since the 1970s.

Where, other than Congress can notes be redeemed?

QUES: In addition, Mahayana Buddhists believe there are innumerable other Buddhas in other universes. A Theravada commentary says that Buddhas arise one at a time in this world element, and not at all in others. The understandings of this matter reflect widely differing interpretations of basic terms, such as "world realm", between the various schools of Buddhism.
Who believes there are innumerable other Buddhas in other universes?

ANS: Mahayana Buddhists

The first task of a database designer is to produce a conceptual data model that reflects the structure of the information to be held in the database. A common approach to this is to develop an entity-relationship model, often with the aid of drawing tools. Another popular approach is the Unified Modeling Language. A successful data model will accurately reflect the possible state of the external world being modeled: for example, if people can have more than one phone number, it will allow this information to be captured. Designing a good conceptual data model requires a good understanding of the application domain; it typically involves asking deep questions about the things of interest to an organisation, like "can a customer also be a supplier?", or "if a product is sold with two different forms of packaging, are those the same product or different products?", or "if a plane flies from New York to Dubai via Frankfurt, is that one flight or two (or maybe even three)?". The answers to these questions establish definitions of the terminology used for entities (customers, products, flights, flight segments) and their relationships and attributes.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What must one understand in order to create a successful data model?
Ah, so.. the application domain

Question: The Pala Empire (Bengali: Pal Samrajyo) flourished during the Classical period of India, and may be dated during 7501174 CE. Founded by Gopala I, it was ruled by a Buddhist dynasty from Bengal in the eastern region of the Indian subcontinent. Though the Palas were followers of the Mahayana and Tantric schools of Buddhism, they also patronised Shaivism and Vaishnavism. The morpheme Pala, meaning "protector", was used as an ending for the names of all the Pala monarchs. The empire reached its peak under Dharmapala and Devapala. Dharmapala is believed to have conquered Kanauj and extended his sway up to the farthest limits of India in the northwest. The Pala Empire can be considered as the golden era of Bengal in many ways. Dharmapala founded the Vikramashila and revived Nalanda, considered one of the first great universities in recorded history. Nalanda reached its height under the patronage of the Pala Empire. The Palas also built many viharas. They maintained close cultural and commercial ties with countries of Southeast Asia and Tibet. Sea trade added greatly to the prosperity of the Pala kingdom. The Arab merchant Suleiman notes the enormity of the Pala army in his memoirs.
Try to answer this question if possible: What educational center reached it height during the Pala rule?
Answer: Nalanda

Problem: The first railways in Thuringia had been built in the 1840s and the network of main lines was finished around 1880. By 1920, many branch lines had been built, giving Thuringia one of the densest rail networks in the world before World War II with about 2,500 km of track. Between 1950 and 2000 most of the branch lines were abandoned, reducing Thuringia's network by half compared to 1940. On the other hand, most of the main lines were refurbished after 1990, resulting in improved speed of travel. The most important railway lines at present are the Thuringian Railway, connecting Halle and Leipzig via Weimar, Erfurt, Gotha and Eisenach with Frankfurt and Kassel and the Saal Railway from Halle/Leipzig via Jena and Saalfeld to Nuremberg. The former has an hourly ICE/IC service from Dresden to Frankfurt while the latter is served hourly by ICE trains from Berlin to Munich. In 2017, a new high speed line will be opened, diverting long-distance services from these mid-19th century lines. Both ICE routes will then use the ErfurtLeipzig/Halle high-speed railway, and the Berlin-Munich route will continue via the NurembergErfurt high-speed railway. Only the segment west of Erfurt of the Frankfurt-Dresden line will continue to be used by ICE trains after 2017, with an increased line speed of 200 km/h (currently 160 km/h). Erfurt's central station, which was completely rebuilt for this purpose in the 2000s (decade), will be the new connection between both ICE lines. The most important regional railway lines in Thuringia are the NeudietendorfRitschenhausen railway from Erfurt to Wurzburg and Meiningen, the WeimarGera railway from Erfurt to Chemnitz, the SangerhausenErfurt railway from Erfurt to Magdeburg, the GothaLeinefelde railway from Erfurt to Gottingen, the HalleKassel railway from Halle via Nordhausen to Kassel and the LeipzigHof railway from Leipzig via Altenburg to Zwickau and Hof. Most regional and local lines have hourly service, but some run only every other hour.
When will the new high speed train be open?

Answer:
In 2017, a new high speed line will be opened,
