instruction:
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.
question:
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.
answer:
How many weapons did the P-38E have in its last configuration?

Passage: Hoping to rebound from their divisional home loss to the Redskins, the Eagles flew to Candlestick Park for a Week 5 Sunday night duel with the San Francisco 49ers.  Kevin Kolb was back under center for the eagles in this game .Philadelphia trailed early in the first quarter as 49ers quarterback Alex Smith completed a 7-yard touchdown pass to wide receiver Michael Crabtree, yet the Eagles responded with quarterback Kevin Kolb finding tight end Brent Celek on an 8-yard touchdown pass.  Philadelphia would take the lead in the second quarter as kicker David Akers booted a 33-yard field goal, followed a 39-yard touchdown run from running back LeSean McCoy.  Afterwards, San Francisco would close out the half with a 50-yard field goal from kicker Joe Nedney.  After a scoreless third quarter, the Eagles added onto their lead in the fourth quarter as safety Quintin Mikell returned a fumble 52 yards for a touchdown.  The 49ers began to rally as Smith connected a 7-yard touchdown pass to tight end Vernon Davis, yet Akers came right back as he gave Philadelphia a 45-yard field goal.  San Francisco tried to rally as Smith completed a 1-yard touchdown pass to running back Frank Gore, yet Philadelphia's defense held on to preserve the victory.
answer:
How many combined points did both teams score in the third quarter?


question:
Passage: The war is known by several names. "Polish-Soviet War" is the most common but other names include "Russo-Polish War  of 1919-1921"  and "Polish-Bolshevik War". This second term ) is most common in Polish sources. In some Polish sources it is also referred as the "War of 1920" . There is disagreement over the dates of the war. The Encyclopædia Britannica begins its article with the date range 1919-1920 but then states, "Although there had been hostilities between the two countries during 1919, the conflict began when the Polish head of state Józef Pilsudski formed an alliance with the Ukrainian nationalist leader Symon Petlyura  and their combined forces began to overrun Ukraine, occupying Kiev on 7 May." The Polish Internetowa encyklopedia PWN, as well as Western historians such as Norman Davies, consider 1919 the starting year of the war. The ending date is given as either 1920 or 1921; this confusion stems from the fact that while the ceasefire was put in force in the autumn of 1920, the official treaty ending the war was signed months later, in March 1921. While the events of 1919 can be described as a border conflict, and only in early 1920 did both sides engage in all-out war, the conflicts that took place in 1920 were an inevitable escalation of fighting that began in earnest a year earlier. In the end, the events of 1920 were a logical, though unforeseen, consequence of the 1919 prelude.
answer:

How many names does the Polish-Soviet War have?
