This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.

Passage: After long negotiations the territorial changes resulting from the conflict were firmly established at the Treaty of Quedlinburg of 13 May 1523. The main import of these changes were significant gains for the princes of Brunswick-Wolfenbuttel, whilst the Prince-Bishopric of Hildesheim was left with just 4 of its original 22 districts as well as the towns of Hildesheim and Peine, the so-called Kleines Stift of some 90 villages. The ecclesiastical boundary of the diocese remained unchanged. The Principality of Brunswick-Wolfenbuttel was awarded the Amter of Winzenburg, Wohldenberg, Steinbruck, Lutter, Wohlenstein, Schladen, Liebenburg, Wiedelah, Vienenburg and Westerhof with the abbeys of Lamspringe, Heiningen, Dorstadt, Woltingerode, Ringelheim and Riechenberg, as well as the towns of Alfeld, Bockenem, Lamspringe and Salzgitter. The Principality of Calenberg received the houses, i.e.fortified seats, and Amter of Hunnesruck with Markoldendorf, Aerzen, Lauenstein, Grohnde, Hallerburg, Poppenburg, Ruthe and Coldingen, the towns of Dassel, Bodenwerder, Gronau, Elze, Sarstedt, half of Hameln and the abbeys of Marienau, Escherde, Wittenburg, Wulfinghausen and Derneburg. Hildesheim immediately began a legal fight for the return of its Groes Stift . This finally ended in 1643 in the Main Treaty of Hildesheim with a revision of the Treaty of Quedlinburg and return of most of the territories. Exceptions were the Amter of Aerzen, Grohnde, Coldingen-Lauenberg, Lutter am Barenberge, Westerhof and Lindau, which remained with the principalities of Calenberg and Brunswick-Wolfenbuttel. Prince-bishop John IV gave up the prince-bishopric in 1527 and later became canon of Ratzeburg and died in 1547 in Lubeck.
How many Amters was the Principality of Brunswick-Wolfenbuttel awarded?
