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: Monets Le Pont du chemin de fer a Argenteuil, an 1873 painting of a railway bridge spanning the Seine near Paris, was bought by an anonymous telephone bidder for a record $41.4 million at Christies auction in New York on 6 May 2008.

Just a few weeks later, Le bassin aux nympheas (from the water lilies series) sold at Christies 24 June 2008 auction in London, lot 19, for 36,500,000 ($71,892,376.34) (hammer price) or 40,921,250 ($80,451,178) with fees, nearly doubling the record for the artist and representing one of the top 20 List of most expensive paintings at the time.
Output:
How many days after Monets Le Pont du chemin de fer a Argenteuil was bought was Le bassin aux nympheas sold?
