Problem: The Blitz:

German beacons operated on the medium-frequency band and the signals involved a two-letter Morse identifier followed by a lengthy time-lapse which enabled the Luftwaffe crews to determine the signal's bearing. The Meacon system involved separate locations for a receiver with a directional aerial and a transmitter. The receipt of the German signal by the receiver was duly passed to the transmitter, the signal to be repeated. The action did not guarantee automatic success. If the German bomber flew closer to its own beam than the Meacon then the former signal would come through the stronger on the direction finder. The reverse would apply only if the meacon were closer.

The German beacons used what frequency band?

A: medium

Problem: The iconic department stores of New Zealand's three major centres are Smith & Caughey's (founded 1880), in New Zealand's most populous city, Auckland; Kirkcaldie & Stains (founded 1863) in the capital, Wellington; and Ballantynes (founded 1854) in New Zealand's second biggest city, Christchurch. These offer high-end and luxury items. Additionally, Arthur Barnett (1903) operates in Dunedin. H & J Smith is a small chain operating throughout Southland with a large flagship store in Invercargill. Farmers is a mid-range national chain of stores (originally a mail-order firm known as Laidlaw Leeds founded in 1909). Historical department stores include DIC. Discount chains include The Warehouse, Kmart Australia, and the now-defunct DEKA.
Where isn't H & J Smith's flagship store?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Exclusive Jurisdiction is a concept whereby only one Grand Lodge will be recognised in any geographical area. If two Grand Lodges claim jurisdiction over the same area, the other Grand Lodges will have to choose between them, and they may not all decide to recognise the same one. (In 1849, for example, the Grand Lodge of New York split into two rival factions, each claiming to be the legitimate Grand Lodge. Other Grand Lodges had to choose between them until the schism was healed.) Exclusive Jurisdiction can be waived when the two over-lapping Grand Lodges are themselves in Amity and agree to share jurisdiction (for example, since the Grand Lodge of Connecticut is in Amity with the Prince Hall Grand Lodge of Connecticut, the principle of Exclusive Jurisdiction does not apply, and other Grand Lodges may recognise both).
When can Exclusive Jurisdiction be waived?
A: when the two over-lapping Grand Lodges are themselves in Amity and agree to share jurisdiction

Context and question: Windows 8 was distributed as a retail box product on DVD, and through a digital download that could be converted into DVD or USB install media. As part of a launch promotion, Microsoft offered Windows 8 Pro upgrades at a discounted price of US$39.99 online, or $69.99 for retail box from its launch until January 31, 2013; afterward the Windows 8 price has been $119.99 and the Pro price $199.99. Those who purchased new PCs pre-loaded with Windows 7 Home Basic, Home Premium, Professional, or Ultimate between June 2, 2012 and January 31, 2013 could digitally purchase a Windows 8 Pro upgrade for US$14.99. Several PC manufacturers offered rebates and refunds on Windows 8 upgrades obtained through the promotion on select models, such as Hewlett-Packard (in the U.S. and Canada on select models), and Acer (in Europe on selected Ultrabook models). During these promotions, the Windows Media Center add-on for Windows 8 Pro was also offered for free.

Question: Codd's paper was picked up by two people at Berkeley, Eugene Wong and Michael Stonebraker. They started a project known as INGRES using funding that had already been allocated for a geographical database project and student programmers to produce code. Beginning in 1973, INGRES delivered its first test products which were generally ready for widespread use in 1979. INGRES was similar to System R in a number of ways, including the use of a "language" for data access, known as QUEL. Over time, INGRES moved to the emerging SQL standard.
Is there an answer to this question: What was the name of the project to steal a geographical database?

Answer: unanswerable

QUES: While the original Xbox sold poorly in Japan, selling just 2 million units while it was on the market (between 2002 and 2005),[citation needed] the Xbox 360 sold even more poorly, selling only 1.5 million units from 2005 to 2011. Edge magazine reported in August 2011 that initially lackluster and subsequently falling sales in Japan, where Microsoft had been unable to make serious inroads into the dominance of domestic rivals Sony and Nintendo, had led to retailers scaling down and in some cases discontinuing sales of the Xbox 360 completely.

When did Edge report Sony sales were falling?
