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.
Q: Passage: After the Polish-Lithuanian-Teutonic War of 1410-1411 not all issues between the Grand Duchy of Lithuania and Teutonic Knights were settled. The most contentious matter was the border between Samogitia and Prussia. Grand Duke of Lithuania Vytautas the Great demanded the entire right bank of the Neman River including the town of Memel . The Knights demanded that after deaths of Vytautas and Jogaila, King of Poland, Samogitia would pass to them. Sigismund, Holy Roman Emperor, agreed to mediate the dispute and appointed Benedict Makrai to hear the arguments. On 3 May 1413, Benedict made the decision and recognized the right bank of the Neman River, including Klaipeda, to Lithuania. The Knights refused to accept this decision and Teutonic Grand Master Heinrich von Plauen ordered Teutonic armies into northern Poland. The army, commanded by Michael Kuchmeister von Sternberg, returned into Prussia after just 16 days of campaign. The knights did not believe that the Order, still recovering from the defeat in the Battle of Grunwald in 1410, was ready for another war with Poland. Kuchmeister deposed von Plauen and became the Grand Master. He attempted to reopen the negotiations with Poland in May 1414. As King Jogaila demanded to reinstate von Plauen and refused any attempts at a compromise, the talks broke down.
A:
Benedict made the decision and recognized the right bank of the Neman River how many years before He attempted to reopen the negotiations with Poland?
