Definition: 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: Prices remained high in Dawson and supply fluctuated according to the season. During the winter of 1897 salt became worth its weight in gold, while nails, vital for construction work, rose in price to $28 per lb . Cans of butter sold for $5 each. The only eight horses in Dawson were slaughtered for dog food as they could not be kept alive over the winter. The first fresh goods arriving in the spring of 1898 sold for record prices, eggs reaching $3 each and apples $1 . Under these conditions scurvy, a potentially fatal illness caused by the lack of vitamin C, proved a major problem in Dawson City, particularly during the winter where supply of fresh food was not available. English prospectors gave it the local name of "Canadian black leg", on account of the unpleasant effects of the condition. It struck, among others, writer Jack London and, although not fatal in his case, brought an end to his mining career. Dysentery and malaria were also common in Dawson, and an epidemic of typhoid broke out in July and ran rampant throughout the summer. Up to 140 patients were taken into the newly constructed St Mary's Hospital and thousands were affected. Measures were taken by the following year to prevent further outbreaks, including the introduction of better sewage management and the piping in of water from further upstream. These gave improvements in 1899, although typhoid remained a problem. The new Han reserve, however, lay downstream from Dawson City, and here the badly contaminated river continued to contribute to epidemics of typhoid and diphtheria throughout the gold rush.
Output:
How many dollars did a can of butter and a egg cost in 1897-98 in Dawson?
