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: On 28 December 1942, a group of young Burmese independence activists, called the Thirty Comrades, who had received military training by the Japanese, founded the Burma Independence Army in Bangkok. The army led by Aung San fought in the Burma Campaign on the side of the Imperial Japanese Army. It saw a significant engagement at Shwedaung near Prome against the British in March 1942. Thousands of young men joined its ranksreliable estimates range from 15,000 to 23,000. The great majority of the recruits were Burman, with little ethnic minority representation. Many of the fresh recruits lacked discipline. At Myaungmya in the Irrawaddy delta, an ethnic war broke out between Burman BIA men and Karens, with both sides responsible for massacres. The BIA was soon replaced with the Burma Defense Army, founded on 26 August 1942 with three thousand BIA veterans. The army became Burma National Army with Ne Win as its commander on 1 August 1943 when Burma received nominal independence. In late 1944, it had a strength of approximately 15,000. Disillusioned by the Japanese occupation, the BNA realigned with the allied forces on 27 March 1945.
