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 United States Navy (USN) hoped to use the V-1710 in its rigid airships USS Akron (ZRS-4) and USS Macon (ZRS-5), but both were equipped with German-built Maybach VL-2 engines as the V-1710 was still in testing when the Macon was lost in February 1935 (the Akron having been lost in April 1933). The USAAC purchased its first V-1710 in December 1932. The Great Depression slowed development, and it was not until December 14, 1936 that the engine next flew in the Consolidated XA-11A testbed. The V-1710-C6 successfully completed the USAAC 150 hour Type certificate on April 23, 1937 at , the first engine of any type to do so. The engine was then offered to aircraft manufacturers where it powered the prototype Curtiss XP-37s. All entrants in the new pursuit competition were designed around it, powering the Lockheed P-38, Bell P-39 and Curtiss P-40. When war British Purchasing Commission asked North American Aviation to build the P-40 under license, NAA instead proposed their own improved aircraft design, using the V-1710 in their North American P-51 Mustang.

Answer: How many airships did the United States Navy (USN) hope to use the V-1710 in?


Question: Passage: Looking to muster their first winning streak of the season, the Washington Redskins took on the rival New York Giants on Monday Night Football. To add to the fanfare, Redskins owner Daniel Snyder hired Bruce Allen to be the new General Manager. However, the Redskins came out flat, and trailed 24-0 by halftime. With a chance to kick a field goal as the half ended to cut it to a 24-3 deficit, the Redskins tried one of the most ill-advised and ill-fated fake field goal attempts of all-time. Redskins P Hunter Smith sent the entire offensive line in motion, along with K Graham Gano. The first attempt was foiled by a Giants time-out. The second attempt was intercepted and almost taken back for a 31-0 lead. In the 2nd half, the Redskins finally got on the board, scoring on a touchdown pass to Fred Davis. However, it was too little, too late, as K Graham Gano missed the extra point. The Redskins would not score again until it was 38-6 Giants. RB Quinton Ganther scored on a 2-yard scamper, but the Redskins came up a foot short on the 2-point conversion, which sealed any slim chance there was of a comeback. When all was said and done, the Giants won 45-12. With the crushing loss, Washington fell to 4-10, losing 10 games or more for the third time in six seasons.

Answer: How many points did the Giants win by?


Question: Passage: The Czech lands were among the first industrialized countries in continental Europe during the German Confederation era. The Czech industrial tradition dates back to the 19th century, when the Lands of the Bohemian Crown were the economic and industrial heartland of the Austrian Empire and later the Austrian side of Austria-Hungary. The Czech lands produced a majority  of all industrial goods in the Empire, some of which were almost monopolistic. The Czechoslovak crown was introduced in April 1919. Introduced at a 1:1 ratio to the Austro-Hungarian currency, it became one of the most stable currencies in Europe. The First Republic became one of the 10 most developed countries of the world . The consequences of the 1938 Munich Agreement and subsequent occupation were disastrous for the economy. After the occupation and forced subordination of the economy to German economic interests, the crown was officially pegged to the mark at a ratio of 1:10, even though the unofficial exchange rate was 1 to 6-7 and Germans immediately started buying Czech goods in large quantities. In accordance with Stalin's development policy of planned interdependence, all the economies of the socialist countries were tightly linked to that of the Soviet Union. Czechoslovakia was the most prosperous country in the Eastern Bloc, however it continued to lag further behind the rest of the developed world. With the disintegration of the communist economic alliance in 1991, Czech manufacturers lost their traditional markets among former communist countries in the east. Today, this heritage is both an asset and a liability. The Czech Republic has a well-educated population and a well-developed infrastructure.

Answer:
Disintegration of the communist economic alliance took place how many years after the Munich Agreement?
