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: Anaukpetlun then brought trans-Salween Shan states under his rule in the 1620s. In February 1622, his forces  took Kengtung, which had been held by an ally of Lan Xang, after a fierce battle. Reinforced Burmese armies led by the king's brothers Thalun and Minye Kyawswa II invaded the Chinese Shan states in present-day southern Yunnan in May 1622. For the next 20 months, Burmese forces chased Kenghung troops. Finally in January 1624, Kenghung and Kengyun both surrendered. Kengyun promptly rebelled the following year but it was put down in December 1626 by the king's brothers. By then, Nyaungyan and Anaukpetlun had restored much of Bayinnaung's empire. Only Siam and Lan Xang remained outside the Restored Toungoo Empire. But the Burmese would not overstretch again. They would not launch major invasions against these neighbours until the 1760s.
Anaukpetlun's forces took Kengtung how many years before Kenghung and Kengyun both surrendered?

Passage: In the USA an estimate was found of 32,500 children (<21 years) that suffer from major paediatric amputation, with 5,525 new cases each year, of which 3,315 congenital. Carr et al. (1998) investigated amputations caused by landmines for Afghanistan, Bosnia and Herzegovina, Cambodia and Mozambique among children (<14 years), showing estimates of respectively 4.7, 0.19, 1.11 and 0.67 per 1000 children. Mohan (1986) indicated in India a total of 424,000 amputees (23,500 annually), of which 10.3% had an onset of disability below the age of 14, amounting to a total of about 43,700 limb deficient children in India alone.
How many amputees in India in all are not children?

Passage: The city of Bangkok has a population of 8,280,925 according to the 2010 census, or 12.6 percent of the national population. In 2018, the population has been estimated to be about 10 million. Roughly half are internal Thai immigrants from other provinces. Only 5,692,284 residents, belonging to 2,672,423 households, registered Bangkok as their legal domicile. A large number of Bangkoks daytime population commutes from surrounding provinces in the Bangkok Metropolitan Region, the total population of which is 14,565,547. Bangkok is a cosmopolitan city; the census showed that it is home to 81,570 Japanese and 55,893 Chinese nationals, as well as 117,071 expatriates from other Asian countries, 48,341 from Europe, 23,418 from the Americas, 5,289 from Australia and 3,022 from Africa. Immigrants from neighbouring countries include 303,595 Burmese, 63,438 Cambodians and 18,126 Lao. In 2018, numbers show that there are 370,000 international migrants registered with the Department of Employment, more than half of them migrants from Cambodia, Laos, and Myanmar.

Approximately how many more people live in Bangkok in 2018 compared to 2010?
