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.

Q: Passage: Watson is the only golfer to score a round of 67 or less in all 4 majors at least once in 4 different decades. His best round in the Masters is a 67. His first 67 came in 1977.

He scored 65 in 1987 and 2003, 66 in 1993 and he first shot 67 in 1975. At the British Open, Watsons low score is a 64 in 1980. 65s were scored in 1977 (twice), 1994 and 2009 (all 65s at the Open were scored at Turnberry). Finally at the PGA Championship, Watsons low score of the 1970s was a 66 in 1979. In the 1980s he scored a 67 in 1980, 1983, 1985, and 1989. His low PGA score is a 65 in 1993 & 2000.

Q: Passage: In the first four years of the Chávez presidency, the economy grew at first (1999–2001), then contracted from 2001–2003 to GDP levels similar to 1997. At first, the economic decline was due to low oil prices, but it was fueled by the turmoil of the 2002 Venezuelan coup détat attempt and the Venezuelan general strike of 2002–03. Other factors of the decline were an exodus of capital from the country and a reluctance of foreign investors. GDP was 50.0 trillion bolivares in 1998. At the bottom of the recession in 2003, it was 42.4 trillion bolivares (in constant 1998 bolivares). However, GDP rebounded 50.1 trillion bolivares with a calmer political situation in 2004 and rose to 66.1 trillion bolivares in 2007 (both in constant 1998 bolivares).

A: Was the GDP larger in 1998 or in 2003?

Q: Passage: The Greco-Turkish War of 1919-1922 was fought between Greece and the Turkish National Movement during the partitioning of the Ottoman Empire after World War I between May 1919 and October 1922. It is known as the Western Front  of the Turkish War of Independence in Turkey and the Asia Minor Campaign  or the Asia Minor Catastrophe  in Greece. The Greek campaign was launched primarily because the western Allies, particularly British Prime Minister David Lloyd George, had promised Greece territorial gains at the expense of the Ottoman Empire, recently defeated in World War I. The armed conflict started when the Greek forces landed in Smyrna , on 15 May 1919. They advanced inland and took control of the western and northwestern part of Anatolia, including the cities of Manisa, Balıkesir, Aydın, Kütahya, Bursa and Eskişehir. Their advance was checked at the Battle of Sakarya in 1921 by forces of the Turkish national movement. The Greek front collapsed with the Turkish counter-attack in August 1922, and the war effectively ended with the recapture of Smyrna by the Turkish forces and the Great Fire of Smyrna. As a result, the Greek government accepted the demands of the Turkish national movement and returned to its pre-war borders, thus leaving East Thrace and Western Anatolia to Turkey. The Allies abandoned the Treaty of Sèvres to negotiate a new treaty at Lausanne with the Turkish National Movement. The Treaty of Lausanne recognized the independence of the Republic of Turkey and its sovereignty over Asia Minor, Constantinople, and Eastern Thrace. Greek and Turkish governments agreed to engage in a population exchange.

A:
For how many years did the Greco-Turkish war last?
