You will be given a definition of a task first, then some input of the task.
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: The Dutch garrison of Recife was increased in March 1640 by 2,500 soldiers carried aboard 28 ships under Amidrals Cornelis Jol and Jan Lichthart, who was in charge of naval operations to disrupt the Portuguese sugar trade. In December Portugal revolted against the Spanish Habsburg rule, proclaiming the seventh Duke of Braganca as King Joao IV in place of Philip IV of Spain. Although the Dutch welcomed the news of the revolt, expecting the Portuguese to become their allies, this did not happen, as the Dutch had no wish to restore the occupied territories to Portugal. Recife served as base for an expedition under Jol and Lichthart, in 1641, to seize Portugal's slaving depots in Angola before any treaty could be concluded in Europe, and despite a ten-year truce between both countries that was signed on 12 June, the hostilities continued, resulting in the expulsion of the Dutch from Brazil in 1654.
Output:
Around how many soldiers were on each ship if spread out evenly?
