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: Granada has a hot-summer Mediterranean climate (Csa) close to a cold semi-arid climate (BSk) Summers are hot and dry with daily temperatures averaging in the hottest month (July); however, temperatures reaching over are not uncommon in the summer months. Winters are cool and damp, with most of the rainfall concentrated from November through to January. The coldest month is January with daytime temperatures hovering at and dropping to around during the night. Frost is quite common as temperatures usually reach below-freezing in the early morning. Spring and autumn are unpredictable, with temperatures ranging from mild to warm. Early summer in 2017 confronted the city with two massive heat waves that broke long-standing record temperatures starting on June 13, 2017, with a new maximum high for the month at 40.6 C (old record 40.0), which was topped three times within the span of four days at 40.9 C on June 14, 41.3 (June 15) and, eventually, 41.5 (June 17). The first two days of this heat wave ranked Granada first in both Spain and Europe, making it the hottest place on the given days. The second extreme surge in temperatures followed roughly a month later when readings soared to 45.7 and 45.3 C on July 12 and 13, respectively, surpassing the old July record by almost 3 degrees.
A:
How many degrees celsius hotter was the temperature on July 12 compared to July 13 in 2017?
