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: On 2 October 1187 the Ayyubid sultan Saladin captured Jerusalem and large parts of the Crusader states. In an effort to reclaim the Outremer estates, the Third Crusade was launched by King Philip II of France, King Richard I of England, and Emperor Frederick I of the Holy Roman Empire in 1189. Frederick departed with a huge army, defeated a Seljuk contingent near Philomelion and captured Iconium, but then drowned in the Goksu River near Silifke in Cilicia. Upon his death, Frederick's German crusading host, totaling perhaps 12,000 to 15,000 men, mostly disbanded and a much smaller contingent led by Frederick's son Duke Frederick V of Swabia continued to the Holy Land, where they joined the Siege of Acre. The crusade ended in the 1192 Treaty of Ramla signed by Sultan Saladin and King Richard Coeur de Lion, establishing a three-years armistice and allowing the Muslims to retain control over Jerusalem, while the Crusaders maintained Acre, Jaffa, and other key coastal cities.
A:
How many Kings and Emperors launched the Third Crusade?
