TASK DEFINITION: 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.
PROBLEM: Passage: As of the census of 2000, 750,097 people, 286,098 households, and 197,693 families resided in the county.  The population density was 1,553 people per square mile (599/km²). The 297,434 housing units averaged 238 units/km² (616 units/sq mi).  The Race (United States Census) of the county was 86.46% White, 7.46% Black or African American, 0.11% Native American, 4.02% Asian, 0.03% Pacific Islander, 0.75% from other races, and 1.16% from two or more races.  About 2.04% of the population were Hispanic or Latino of any race, 17.5% were of German people, 16.7% Irish people, 14.3% Italian people, 6.5% English people, and 5.0% Polish people ancestry according to 2000 United States Census. Around 90.5% spoke English language, 2.0% Spanish language, 1.1% korean language, and 1.0% Italian language as their first language.  Historically, much of western Montgomery County is part of the Pennsylvania Dutch Country, with a great many descendants of German language-speaking settlers from the 18th century.

SOLUTION: Did more people have Italian or Polish ancestry?

PROBLEM: Passage: The eventual configuration was rare in terms of contemporary fighter aircraft design, with only the preceding Fokker G.1, the contemporary Focke-Wulf Fw 189 Luftwaffe reconnaissance aircraft, and the later Northrop P-61 Black Widow night fighter having a similar planform (aeronautics). The Lockheed team chose twin booms to accommodate the tail assembly, engines, and turbo-superchargers, with a central nacelle for the pilot and armament. The XP-38 gondola mockup was designed to mount two .50-caliber (12.7 mm) M2 Browning machine guns with 200 rounds per gun (rpg), two .30-caliber (7.62 mm) Brownings with 500 rpg, and a T1 Army Ordnance 23 mm (.90 in) autocannon with a rotary magazine as a substitute for the non-existent 25 mm Hotchkiss et Cie aircraft autocannon specified by Kelsey and Saville. In the YP-38s, a M4 cannon with 15 rounds replaced the T1. The 15 rounds were in three five-round clips, an unsatisfactory arrangement according to Kelsey, and the M9 did not perform reliably in flight. Further armament experiments from March to June 1941 resulted in the P-38E combat configuration of four M2 Browning machine guns, and one Hispano-Suiza HS.404 20 mm (.79 in) autocannon with 150 rounds.

SOLUTION: How many weapons did the P-38E have in its last configuration?

PROBLEM: Passage: Soon after gaining independence, the central government led by U Nu faced several armed rebellions. The most serious was the Chinese Nationalist KMT invasion of Shan State in 1950. Driven out by the Chinese Communist forces, Nationalist KMT troops  planned to use the region east of the Salween river as a base from which to regain their homeland. In March 1953, the KMT forces with US assistance were on the verge of taking the entire Shan State, and within a day's march of the state capital Taunggyi. The Burmese army drove back the invaders east across the Salween. The KMT units remained there until 1961 when some 20,000 troops of the People's Liberation Army and 5,000 troops of the Burmese Army defeated them in a joint operation.

SOLUTION:
How many Burmese Army troops and People Liberation Army were there together?
