Problem: George VI:

In 1947, the King and his family toured Southern Africa. The Prime Minister of the Union of South Africa, Jan Smuts, was facing an election and hoped to make political capital out of the visit. George was appalled, however, when instructed by the South African government to shake hands only with whites, and referred to his South African bodyguards as "the Gestapo". Despite the tour, Smuts lost the election the following year, and the new government instituted a strict policy of racial segregation.

What race were the South African bodyguards?

Problem: Boston:

In 1950, whites represented 94.7% of Boston's population. From the 1950s to the end of the 20th century, the proportion of non-Hispanic whites in the city declined; in 2000, non-Hispanic whites made up 49.5% of the city's population, making the city majority-minority for the first time. However, in recent years the city has experienced significant gentrification, in which affluent whites have moved into formerly non-white areas. In 2006, the US Census Bureau estimated that non-Hispanic whites again formed a slight majority. But as of 2010, in part due to the housing crash, as well as increased efforts to make more affordable housing more available, the minority population has rebounded. This may also have to do with an increased Latino population and more clarity surrounding US Census statistics, which indicate a Non-Hispanic White population of 47 percent (some reports give slightly lower figures).

What year did minorities become the majority of the population for the first time?

A: 2000


Problem: East India Company:

In the following decades there was a constant battle between the company lobby and the Parliament. The company sought a permanent establishment, while the Parliament would not willingly allow it greater autonomy and so relinquish the opportunity to exploit the company's profits. In 1712, another act renewed the status of the company, though the debts were repaid. By 1720, 15% of British imports were from India, almost all passing through the company, which reasserted the influence of the company lobby. The licence was prolonged until 1766 by yet another act in 1730.

Who passed the acts that effected the profits of West India company?

A: unanswerable


Problem: MP3:

Karlheinz Brandenburg used a CD recording of Suzanne Vega's song "Tom's Diner" to assess and refine the MP3 compression algorithm. This song was chosen because of its nearly monophonic nature and wide spectral content, making it easier to hear imperfections in the compression format during playbacks. Some refer to Suzanne Vega as "The mother of MP3". This particular track has an interesting property in that the two channels are almost, but not completely, the same, leading to a case where Binaural Masking Level Depression causes spatial unmasking of noise artifacts unless the encoder properly recognizes the situation and applies corrections similar to those detailed in the MPEG-2 AAC psychoacoustic model. Some more critical audio excerpts (glockenspiel, triangle, accordion, etc.) were taken from the EBU V3/SQAM reference compact disc and have been used by professional sound engineers to assess the subjective quality of the MPEG Audio formats.

As a result of her song being used, Suzanne Vega is sometimes referred to as what?

A:
The mother of MP3
