Q: 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: According to Statistics Canada, Pentecostal growth has varied (statistics Canada does not collect data specific to the PAOC, but as by far the largest Pentecostal group in Canada, it is likely to reflect the statistics regarding Canadian Pentecostals). The 1991 census showed a 29% increase. Between 1991 and 2001, the census reported a 15% decline to 369,480 adherents (Extrapolating the percentage growth indicates approximately 435,000 +/-2,500 adherents in 1991). While self-reported statistics from the PAOC show plateaued growth, the 2011 census indicates 478,705 adherents - a 29% increase over 2001, and 10% increase over 1991 census data. The Evangelical Fellowship of Canada has pointed out that changes to choices available on census forms over the years brings into question the accuracy and usefulness of Statistics Canada data on evangelical denominations, so it is likely PAOC data is a more accurate measure. The PAOC had "fewer than 225,000 members and adherents as of 1994," which compared with the 2014 data of 239,267 indicates growth of just 6% in the 20-year period.
A:
How many fewer adherents did the PAOC have in 1991 than in 2001?
