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: After William's landing in England, James' Lord Deputy in Ireland, Richard Talbot, 1st Earl of Tyrconnell took action to ensure that all strong points in Ireland were held by garrisons of the newly recruited Irish Catholic army, loyal to James. The northern province of Ulster, which had the heaviest concentration of English and Scottish settlers, was the only part of Ireland where Talbot encountered significant resistance. An attempted rising by the Protestant inhabitants of Bandon in County Cork was quickly defeated by Jacobite forces. By November 1688, only the walled city of Derry had a Protestant garrison. A Jacobite army of around 1,200 men, mostly "Redshanks" , under Alexander MacDonnell, 3rd Earl of Antrim, was slowly organised . When they arrived on 7 December 1688 the gates were closed against them and the Siege of Derry began. While the Jacobites appeared to have great advantages in terms of numbers in Ireland, in fact, the troops raised by Tyrconnell were mainly hastily conscripted peasant bands, most of them poorly armed and trained. Nevertheless, a Jacobite force under Richard Hamilton routed a Protestant Williamite militia in an encounter at Dromore, County Down on 14 March 1689 and occupied eastern Ulster.
Output:
How many months after the Siege of Derry did a Jacobite force route a Protestant Williamite militia in an encounter at Dromore, County Down?
