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.

Example Input: Passage: Although it failed to dislodge the Burmese from Kengtung and Sipsongpanna at the beginning of the century , Siam never gave up its claims on these lands. They tested the waters in 1849, by raiding as far north as Kengtung. But when the Second Anglo-Burmese War started, the Siamese viewed it as their opportunity to take over the trans-Salween states. In late 1852, a large infantry and elephant force marched from Chiang Mai and launched a two-pronged invasion of Kengtung. Burma couldrespond only after the new king Mindon had seized power in February 1853. Because he was still concerned about the British threat, Mindon could only send several thousand infantry troops from the Mone  garrison to relieve the Siamese siege of Kengtung. With the troops by Kenghung sawbwa, the Burmese eventually drove out the Siamese but only after heavy loss of life. In 1854, the largest Siamese invasion force, consisted of Laotian levies, tried once more. But this time, with the British front quiet, the Burmese were ready. Mindon had deployed a larger, well-equipped army . The Siamese forces again reached Kengtung but could not break through. The Siamese forces withdrew to the border in May 1855.
Example Output: How many animal forces did the Siamese take with them in 1852?

Example Input: Passage: During the first game of the 2014-15 Los Angeles Lakers season season, the 7th overall pick in the 2014 NBA draft, Julius Randle went down with a broken leg, which ended his rookie season. The Lakers began their season losing 10 of their first 16 games. After playing only 35 games, Kobe Bryant tore a rotator cuff in his shoulder ending his season. Nick Young (basketball) was also forced to end his season with a fractured kneecap, leaving the team with a record of 14-41. With 27 games left in the regular season, Byron Scott gave rookie Jordan Clarkson more playing time. Clarkson, the 46th overall pick in the 2014 draft, finished his rookie season with game stats of 11.9 ppg, 3.2 rpg, 3.5 apg, and shooting 44.8% from the field. The Lakers season ended with a record of 21-61, the 4th worst record in the league and at the time the worst record in franchise history.
Example Output: How many games did the Lakers win?

Example Input: Passage: Following World War II, Britain retained control of both British Somaliland and Italian Somaliland as protectorates. In 1950, as a result of the Paris Peace Treaties, the United Nations granted Italy trusteeship of Italian Somaliland, but only under close supervision and on the condition—first proposed by the Somali Youth League  and other nascent Somali political organizations, such as Hizbia Digil Mirifle Somali  and the Somali National League —that Somalia achieve independence within ten years. British Somaliland remained a protectorate of Britain until 1960. In 1948, under pressure from their World War II allies and to the dismay of the Somalis, the British returned the Haud  and the Ogaden to Ethiopia, based on a treaty they signed in 1897 in which the British, French and Italians agreed upon the territorial boundaries of Ethiopia with the Ethiopian Emperor Menelik in exchange for his help against raids by hostile clans. Britain included the provision that the Somali residents would retain their autonomy, but Ethiopia immediately claimed sovereignty over the area. This prompted an unsuccessful bid by Britain in 1956 to buy back the Somali lands it had turned over. Britain also granted administration of the almost exclusively Somali-inhabited Northern Frontier District  to Kenyan nationalists despite an informal plebiscite demonstrating the overwhelming desire of the region's population to join the newly formed Somali Republic.
Example Output:
British Somaliland remained a protectorate of Britain for how many years after the Paris Peace Treaties?
