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: The smallest front of the war was in Catalonia. In 1689 the Duke of Noailles had led French forces there aimed at bringing further pressure to bear on the Spanish by re-igniting a peasant rising against Charles II, which initially broke out in 1687. Exploiting the situation, Noailles captured Camprodon on 22 May, but a larger Spanish army under the Duke of Villahermosa forced him to withdraw back to Roussillon in August. The Catalan campaign settled down in 1690, but a new front in Piedmont-Savoy proved more eventful. A ferment of religious animosities and Savoyard hatred of the French produced a theatre characterised by massacres and atrocities: constant guerrilla attacks by the armed populace were met by draconian reprisals. In 1690 Saint-Ruth took most of the Victor Amadeus II's exposed Duchy of Savoy, routing the Savoyard army in the process until only the great fortress of Montmelian remained in ducal hands; while to the south in Piedmont, Nicolas Catinat led 12,000 men and soundly defeated Victor Amadeus at the Battle of Staffarda on 18 August. Catinat immediately took Saluzzo, followed by Savigliano, Fossano, and Susa, but lacking sufficient troops, and with sickness rife within his army, Catinat was obliged to withdraw back across the Alps for the winter.
How many cities did Catinat take?
