Instructions: 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.
Input: Passage: Khuzestan remained much out of the central Persian reach by 1923. He was supported by the British, who sent him some 3,000 arms and additional ammunition by 1919. Sheykh Khazal had been collecting taxes, but in fact paid a very small fraction to the central government. In 1921, realizing the threat posed by Reza Khan Mirpanj , who had just staged a coup d'etat with Seyyed Zia'eddin Tabatabaee, Khaz'al proceeded to take steps in order to protect himself. In February 1922, the issue of taxation from tribal areas of Mohammerah was reopened by the Iranian government. Shaykh Khazal and Bakhtiari Khan's met between April 29 and May 2, 1922, in Dar-i Khazinah to establish a cooperation; another meeting between the parties in Ahvaz produced a formal document that Khazal and Bakhtiaris would cooperate in every respect, although both would "continue to serve Iranian government faithfully and loyally". The agreement was an important step which paved the way to the establishment of the Southern League. The nucleus of the alliance, based on Shaykh Khazal and the Bakhtiaris, later tried to attract additional elements, including the Vali of Pusht-i Kuh, Qavam al-Mulk of Khamsah and possibly Sawlat al-Dawlah. The League however had no formal existence, being largely a temporary tribal confederation with common interests.
Output:
How many alliances did they try to attract?
