Given the task definition and input, reply with output. 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 Senussi defeats in the Coastal Campaign forced the survivors over the border into Libya and to prevent a revival, the light Fords and armoured cars continued their patrols. The Aulad Ali surrendered to Peyton, having also gone hungry in the famine and public unrest in Alexandria diminished. The South African Brigade returned to Alexandria and two battalions of the Composite Brigade, a company of the Camel Corps, two guns of the Hong Kong Battery, the light armoured cars and the reconnaissance aircraft remained in Sollum, with an RFC half-flight. On 7 April, four light armoured cars and a machine-gun section of the 2/7th Middlesex left Sollum to raid an ammunition dump at Moraisa, 18mi to the north-west and destroyed artillery ammunition and about 120,000 rounds of small-arms ammunition; other patrols that month uncovered another 167,000 rounds. The Italian army posted two battalions at Bardia to co-operate and from 25-26 July, a raiding force from Sollum and Italian cars from Bardia, a party from the Camel Corps and an Italian yacht, Misurat attacked a party of about forty Muhafizia at Wadi Sanal in Libya, 40mi west of Ras el Mehl. The party was scattered and served as a warning that there was no sanctuary on either side of the border. Patrols continued for the year and a camel convoy was captured near Jaghbub, a Senussi stronghold 135mi from Sollum; more combined Italian-British raids were made during the winter.
How many days did a raiding force from Sollum and Italian cars from Bardia, a party from the Camel Corps and an Italian yacht, Misurat attack a party of about forty for?
