Problem: Korean War:

In the resulting Battle of Pusan Perimeter (AugustSeptember 1950), the U.S. Army withstood KPA attacks meant to capture the city at the Naktong Bulge, P'ohang-dong, and Taegu. The United States Air Force (USAF) interrupted KPA logistics with 40 daily ground support sorties that destroyed 32 bridges, halting most daytime road and rail traffic. KPA forces were forced to hide in tunnels by day and move only at night. To deny materiel to the KPA, the USAF destroyed logistics depots, petroleum refineries, and harbors, while the U.S. Navy air forces attacked transport hubs. Consequently, the over-extended KPA could not be supplied throughout the south. On 27 August, 67th Fighter Squadron aircraft mistakenly attacked facilities in Chinese territory and the Soviet Union called the UN Security Council's attention to China's complaint about the incident. The US proposed that a commission of India and Sweden determine what the US should pay in compensation but the Soviets vetoed the US proposal.

What did the US Air Force's daytime attacks cause the KPA to do?

A: to hide in tunnels by day and move only at night

Problem: 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".
But house was also being developed on Ibiza,[citation needed] although no house artists or labels were coming from this tiny island at the time. By the mid-1980s a distinct Balearic mix of house was discernible.[citation needed] Several clubs such as Amnesia with DJ Alfredo were playing a mix of rock, pop, disco and house. These clubs, fueled by their distinctive sound and Ecstasy, began to have an influence on the British scene. By late 1987, DJs such as Trevor Fung, Paul Oakenfold and Danny Rampling were bringing the Ibiza sound to UK clubs such as the Hacienda in Manchester, and in London clubs such as Shoom in Southwark, Heaven, Future and Spectrum.
what was the name of the big dance club in Manchester UK in the late 80s?
A: Hacienda

Context and question: The Recommended Exposure Index (REI) technique, new in the 2006 version of the standard, allows the manufacturer to specify a camera model's EI choices arbitrarily. The choices are based solely on the manufacturer's opinion of what EI values produce well-exposed sRGB images at the various sensor sensitivity settings. This is the only technique available under the standard for output formats that are not in the sRGB color space. This is also the only technique available under the standard when multi-zone metering (also called pattern metering) is used.
Who created the 2006 standard?
Answer: unanswerable

Question: On the recovery side of the flight deck, the adaptation to the aircraft loadout is mirrored. Non-VTOL or conventional aircraft cannot decelerate on their own, and almost all carriers using them must have arrested-recovery systems (-BAR, e.g. CATOBAR or STOBAR) to recover their aircraft. Aircraft that are landing extend a tailhook that catches on arrestor wires stretched across the deck to bring themselves to a stop in a short distance. Post-WWII Royal Navy research on safer CATOBAR recovery eventually led to universal adoption of a landing area angled off axis to allow aircraft who missed the arresting wires to "bolt" and safely return to flight for another landing attempt rather than crashing into aircraft on the forward deck.
Is there an answer to this question: What does a landing area angles off access allow an aircraft to do if it catches the arresting wires?

Answer: unanswerable

Question: On the other hand, certain financial techniques can reduce the impact of such purchases on the currency. One is sterilisation, in which highly valued assets are sold at the same time that the weaker assets are purchased, which keeps the money supply neutral. Another technique is simply to accept the bad assets as long-term collateral (as opposed to short-term repo swaps) to be held until their market value stabilises. This would imply, as a quid pro quo, adjustments in taxation and expenditure in the economies of the weaker states to improve the perceived value of the assets.
Is there an answer to this question: How can weaker states improve the surface value of their assets?

Answer:
adjustments in taxation and expenditure in the economies
