Problem: Literature:

As advances and specialization have made new scientific research inaccessible to most audiences, the "literary" nature of science writing has become less pronounced over the last two centuries. Now, science appears mostly in journals. Scientific works of Aristotle, Copernicus, and Newton still exhibit great value, but since the science in them has largely become outdated, they no longer serve for scientific instruction. Yet, they remain too technical to sit well in most programmes of literary study. Outside of "history of science" programmes, students rarely read such works.

What do students rarely study outside programmes of literary study?

A: unanswerable


Problem: Although STOVL aircraft are capable of taking off vertically from a spot on the deck, using the ramp and a running start is far more fuel efficient and permits a heavier launch weight. As catapults are unnecessary, carriers with this arrangement reduce weight, complexity, and space needed for complex steam or electromagnetic launching equipment, vertical landing aircraft also remove the need for arresting cables and related hardware. Russian, Chinese, and future Indian carriers include a ski-jump ramp for launching lightly loaded conventional fighter aircraft but recover using traditional carrier arresting cables and a tailhook on their aircraft.
What landing aircraft have removed the need for arresting cables?

Answer: vertical


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Windows 8 introduces a new style of application, Windows Store apps. According to Microsoft developer Jensen Harris, these apps are to be optimized for touchscreen environments and are more specialized than current desktop applications. Apps can run either in a full-screen mode, or be snapped to the side of a screen. Apps can provide toast notifications on screen or animate their tiles on the Start screen with dynamic content. Apps can use "contracts"; a collection of hooks to provide common functionality that can integrate with other apps, including search and sharing. Apps can also provide integration with other services; for example, the People app can connect to a variety of different social networks and services (such as Facebook, Skype, and People service), while the Photos app can aggregate photos from services such as Facebook and Flickr.
What apps can one expect the Photos app to match with?
A: Facebook and Flickr


Context and question: The king appoints the prime minister from the legislature and also appoints a minority of legislators to both chambers of the Libandla (parliament) with help from an advisory council. The king is allowed by the constitution to appoint some members to parliament for special interests. These special interests are citizens who might have been left out by the electorate during the course of elections or did not enter as candidates. This is done to balance views in parliament. Special interests could be people of gender, race, disability, the business community, civic society, scholars, chiefs and so on.
Who does the prime minister appoint?
Answer: unanswerable


Question: Residents of Norfolk Island do not pay Australian federal taxes, creating a tax haven for locals and visitors alike. Because there is no income tax, the island's legislative assembly raises money through an import duty, fuel levy, medicare levy, GST of 12% and local/international phone calls. In a move that apparently surprised many islanders the Chief Minister of Norfolk Island, David Buffett, announced on 6 November 2010 that the island would voluntarily surrender its tax free status in return for a financial bailout from the federal government to cover significant debts. The introduction of income taxation will now come into effect on July 1, 2016, with a variation of opinion on the island about these changes but with many understanding that for the island's governance to continue there is a need to pay into the commonwealth revenue pool so that the island can have assistance in supporting its delivery of State government responsibilities such as health, education, medicare, and infrastructure. Prior to these reforms residents of Norfolk Island were not entitled to social services. It appears that the reforms do extend to companies and trustees and not only individuals.
Is there an answer to this question: When will income tax be introduced on Norfolk Island?

Answer: July 1, 2016
