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.

Passage: In 2011, the Thessaloniki (regional unit) had a Gross Domestic Product of Euro18.293 billion (ranked 2nd amongst the countrys regional units), comparable to Bahrain or Cyprus, and a per capita of €15,900 (ranked 16th).

question:
Passage: The Crusade of 1197, also known as the Crusade of Henry VI  or the German Crusade  was a crusade launched by the Hohenstaufen emperor Henry VI in response to the aborted attempt of his father, Emperor Frederick Barbarossa during the Third Crusade in 1189-90. Thus the military campaign is also known as the "Emperor's Crusade" . While his forces were already on their way to the Holy Land, Henry VI died before his departure in Messina on 28 September 1197. The emerging throne conflict between his brother Philip of Swabia and the Welf rival Otto of Brunswick made many higher-ranking crusaders return to Germany in order to protect their interests in the next imperial election. The nobles remaining on the campaign captured the Levant coast between Tyre and Tripoli before returning to Germany. The Crusade ended abruptly after the fall of Sidon and Beirut in 1198.
answer:

How many total years did the Third Crusade last?
