You will be given a definition of a task first, then some input of the task.
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: The uprising greatly reduced the Tver Principality's power in the northeastern remains of Kievan Rus'. In 1328, Oz Beg granted Ivan Kalita the duchies of Novgorod and Kostroma. Alexander Vasilyevich, the prince of Suzdal, received Vladimir and a region encompassing present day Nizhny Novgorod and Gorodets. By granting the more prestigious Vladimir to the weaker of the two princes, Oz Beg maintained adherence to the principle of "divide and rule," reasoning that Moscow's jealousy of Suzdal's lands would prevent them from allying to fight against the Golden Horde. Alexander moved to Sweden after his time in Lithuania, and then back to Pskov after the city's excommunication was lifted, under the patronage of Gediminas, Grand Duke of Lithuania. In 1335, he gained forgiveness from Oz Beg and was allowed to return to his former position in Tver, however by then, the state had lost most of its influence, being replaced by the Grand Duchy of Muscovy. This return did not last long, as both Alexander and his son Fyodor were taken to Sarai and quartered in 1339. Following the execution of Alexander Vasilievich in 1331, Ivan received the duchy of Vladimir and became the sole ruler of northeastern Russia. Favor from the khan of the Golden Horde allowed Moscow to gain power rapidly at the expense of Tver, with Tver eventually losing all influence to Moscow. However, a new rivalry was formed between the princes of Suzdal-Nizhny Novgorod. The relative power of Moscow and their strong alliance with the Horde led to a period of relative peace in Russia that was not interrupted until the reign of Dmitry Donskoy, the first prince of Moscow to openly challenge the Horde. He would later defeat them at the Battle of Kulikovo in 1380.
Output:
How many years after Alexander Vasilievich received Vladimir and a region encompassing present day Nizhny Novgorod and Gorodets was he executed?
