Problem: Windows 8:

Windows 8 development started before Windows 7 had shipped in 2009. At the Consumer Electronics Show in January 2011, it was announced that the next version of Windows would add support for ARM system-on-chips alongside the existing x86 processors produced by vendors, especially AMD and Intel. Windows division president Steven Sinofsky demonstrated an early build of the port on prototype devices, while Microsoft CEO Steve Ballmer announced the company's goal for Windows to be "everywhere on every kind of device without compromise." Details also began to surface about a new application framework for Windows 8 codenamed "Jupiter", which would be used to make "immersive" applications using XAML (similarly to Windows Phone and Silverlight) that could be distributed via a new packaging system and a rumored application store.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
A predator's effect on its prey species is hard to see in the short-term. However, if observed over a longer period of time, it is seen that the population of a predator will correlationally rise and fall with the population of its prey in a cycle similar to the boom and bust cycle of economics. If a predator overhunts its prey, the prey population will lower to numbers that are too scarce for the predators to find. This will cause the predator population to dip, decreasing the predation pressure on the prey population. The decrease in predators will allow the small number of prey left to slowly increase their population to somewhere around their previous abundance, which will allow the predator population to increase in response to the greater availability of resources. If a predator hunts its prey species to numbers too low to sustain the population in the short term, they can cause not only the extinction or extirpation of the prey but also the extinction of their own species, a phenomenon known as coextinction. This is a risk that wildlife conservationists encounter when introducing predators to prey that have not coevolved with the same or similar predators. This possibility depends largely on how well and how fast the prey species is able to adapt to the introduced predator. One way that this risk can be avoided is if the predator finds an alternative prey species or if an alternative prey species is introduced (something that ecologists and environmentalists try to avoid whenever possible). An alternative prey species would help to lift some of the predation pressure from the initial prey species, giving the population a chance to recover, however it does not guarantee that the initial prey species will be able to recover as the initial prey population may have been hunted to below sustainable numbers or to complete extinction.
When are the effects of economics hard to see?
A: unanswerable


Context and question: In 1933, Herbert Chapman, wanting his players to be more distinctly dressed, updated the kit, adding white sleeves and changing the shade to a brighter pillar box red. Two possibilities have been suggested for the origin of the white sleeves. One story reports that Chapman noticed a supporter in the stands wearing a red sleeveless sweater over a white shirt; another was that he was inspired by a similar outfit worn by the cartoonist Tom Webster, with whom Chapman played golf. Regardless of which story is true, the red and white shirts have come to define Arsenal and the team have worn the combination ever since, aside from two seasons. The first was 1966–67, when Arsenal wore all-red shirts; this proved unpopular and the white sleeves returned the following season. The second was 2005–06, the last season that Arsenal played at Highbury, when the team wore commemorative redcurrant shirts similar to those worn in 1913, their first season in the stadium; the club reverted to their normal colours at the start of the next season. In the 2008–09 season, Arsenal replaced the traditional all-white sleeves with red sleeves with a broad white stripe.
In what year did Herbert Chapman become manager of Arsenal?

Question: By developing commercial centres and routes, encouraging people to extend the area of cultivated land in the country and international trade through its dominions, the state performed basic economic functions in the Empire. But in all this the financial and political interests of the state were dominant.

Is there an answer to this question: The development of what caused people to expand areas of cultivation in the Ottoman Empire?

Answer: commercial centres and routes
