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: In the aftermath of the 1904 revolution, the Paraguayan liberal movement entered a period of instability and factional fighting. Between 1904 and 1922, 15 Paraguayan presidents assumed office. The coups of 1908 and 1910 cemented the division of Paraguayan liberals into the "radicales" and "civicos" factions. A further split of the radicales faction into two sub-factions led by Manuel Gondra and Eduardo Schaerer respectively, gradually escalated into a full-scale civil war. In 1920, Gondra came out victorious in the presidential election. Schaerer immediately attempted to undermine Gondra by forcing the resignation of Interior Minister Jose Guggiari, Gondra's most vocal supporter. After Gondra's refusal to dismiss Guggiari, Gondra himself resigned, due to the emergence of a split in Paraguay's armed forces. After Vice President Felix Paiva's refusal to assume office, the congress placed senator Eusebio Ayala, a moderate Gondra supporter into interim presidency. Another crisis ensued when Adolfo Chirife, a supporter of Schaerer, became a presidential candidate. Amassing the support of the Colorado party along with a large percentage of supporters in the Liberal Party, Chirife gathered enough support to ensure a victory in the upcoming elections. When Ayla reacted by blocking implementation of the elections, Schaerer's supporters attempted to restore the electoral process by force.
A:
Gondra won the presidential election how many years after the 1904 revolution?
