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: In September 1998, Barzani and Talabani signed the U.S.-mediated Washington Agreement establishing a formal peace treaty. In the agreement, the parties agreed to share revenue, share power, deny the use of northern Iraq to the PKK, and not allow Iraqi troops into the Kurdish regions. The United States pledged to use military force to protect the Kurds from possible aggression by Saddam Hussein. At the same time, implementation of the U.N. Oil-for-Food Programme brought revenue to northern Iraq, allowing for increased standards of living. Iraqi Kurdistan became a relatively peaceful region, before the terrorist group Ansar al-Islam entered the area in December 2001, bringing renewed conflict. Around a month later, U.S. President Bill Clinton signed the Iraq Liberation Act into law, providing for military assistance to Iraqi opposition groups, including the PUK and KDP. The KDP estimated that 58,000 of its supporters had been expelled from PUK-controlled regions from October 1996 to October 1997. The PUK says 49,000 of its supporters were expelled from KDP-controlled regions from August 1996 to December 1997. The PUK and KDP later co-operated with American forces during the 2003 invasion of Iraq, routing Iraqi forces with the help of American air power and overrunning much of northern Iraq including the cities of Kirkuk and Mosul. After the invasion, Massoud Barzani was later elected president of Iraqi Kurdistan while Jalal Talabani was elected President of Iraq.
Output:
How many more supporters were expelled from PUK-controlled regions than KDP-controlled regions?
