Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Passage: The Taungoo-Mrauk-U War ) was a military conflict that took place in Arakan from 1545 to 1547 between the Taungoo Dynasty and the Kingdom of Mrauk U. The western kingdom successfully fended off the Taungoo invasions, and kept its independence. The war had a deterrence effect: Mrauk U would not see another Taungoo invasion until 1580. The war's origins can be traced back to 1542 when King Min Bin of Mrauk U provided military support on the side of the Kingdom of Ava in the Taungoo-Ava War . Although Min Bin left the alliance in the same year, King Tabinshwehti of Taungoo was determined to repay the favor. In 1545, Tabinshwehti agreed to aid Min Aung Hla, the former Viceroy of Thandwe, who had been removed from office by Min Bin. In October 1545, Tabinshwehti sent a 4000-strong army but it was promptly driven back. Much larger Taungoo naval and land forces tried again in the following dry season. The invasion forces overran southern Arakan, and were about to breach the defenses of the capital of Mrauk U when Mrauk U forces opened the sluices of the city's reservoirs, flooding the invaders out. On 30 January 1547, the two sides agreed to a peace treaty that allowed an orderly withdrawal of Taungoo forces from Arakan. The uneasy peace would last for the next 33 years.
