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: Kabuls population is estimated to have been about 10,000 in 1700, 65,000 by 1878, and 120,000 by 1940. More recently, the population was around 500,000 in 1979, whilst another source claims 337,715 as of 1976. This figure rose to about 1.5 million by 1988, before dramatically dropping in the 1990s. Kabul became one of the fastest growing cities in the world, with its population growing fourfold from 2001 to 2014. This was partly due to the return of refugees after the fall of the Taliban regime, and partly due to Afghans moving from other provinces mainly due to war between Taliban insurgents and Afghan government forces in their native areas as well as looking for labor. This resulting rapid urbanization mean that many residents today live in informal settlements. Shanty mud-brick homes on the mountainsides and steep hills have been built by them and these are usually poverty-stricken, not connected to the water and electricity grid. Although the settlements are illegal, they have been tolerated by authorities. In 2017 Kabul Municipality started a project to paint the homes in these settlements in bright colors in an effort to "cheer up" residents.
How many more people lived in Kabuls by 1878 compared to 1700?

Passage: In 1611 a Swedish expeditionary corps under Jacob De la Gardie captured Novgorod. The Novgorodians asked the Swedish king to install one of his sons — Carl Filip or Gustavus Adolphus — as their monarch. In the meantime, Gustavus Adolphus succeeded to the Swedish throne. The young king decided to press his brother's claim to the Russian throne even after the Poles had been expelled from Moscow by a patriotic uprising of 1612 and Mikhail Romanov had been elected a new tsar. While the Swedish statesmen envisaged the creation of a Trans-Baltic dominion extending northwards to Archangelsk and eastwards to Vologda, De la Gardie and other Swedish soldiers, still holding Novgorod and Ingria, saw the war as a reaction for their forces not receiving payment for their succour during the De la Gardie Campaign. In 1613 they advanced towards Tikhvin and laid a siege to the city, but were repelled. The Russian counter-offensive failed to regain Novgorod, however. The Russian tsar refused to commit his troops to battle and the war lumbered on until 1614, when the Swedes captured Gdov. The following year they laid siege to Pskov but Russian generals Morozov and Buturlin held their own until 27 February 1617, when the Treaty of Stolbovo stripped Russia of its access to the Baltic Sea and awarded to Sweden the province of Ingria with the townships of Ivangorod, Jama, Koporye and Noteborg. Novgorod and Gdov were to be restituted to Russia. As a result of the war, Russia was denied access to the Baltic sea for about a century, despite its persistent efforts to reverse the situation. This led to the increased importance of Arkhangelsk for its trading connections with Western Europe.
After the first attack in 1613 how many years passed before the Treaty of Stolbovo was signed?

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, 18 mi  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, 40 mi  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 135 mi  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?
