Problem: CBC Television:

On August 6, 2010, the CBC issued a press release stating that due to financial reasons, the CBC and Radio-Canada would only transition 27 transmitters total, one in each market where there was an originating station (i.e. a CBC or Radio-Canada television station located in that market). Further, the CBC stated in the release, that only 15 of the transmitters would be in place by August 31, 2011 due to lack of available funds, and that the remainder would not be on the air until as late as August 31, 2012. Additionally, the CBC stated in the release that it was asking the CRTC for permission to continue broadcasting in analogue until the identified transmitters for transition were up and running. At the time of the press release, only eight of the corporation's transmitters (four CBC and four Radio Canada) were broadcasting in digital.

How many stations did the CBC have broadcasting in analog in 2012?

Problem: Saint Helena:

Education is free and compulsory between the ages of 5 and 16  The island has three primary schools for students of age 4 to 11: Harford, Pilling, and St Paul’s. Prince Andrew School provides secondary education for students aged 11 to 18. At the beginning of the academic year 2009-10, 230 students were enrolled in primary school and 286 in secondary school.

What are the 3 primary schools called?
---
A: Harford, Pilling, and St Paul’s


Problem: Light-emitting diode:

Phosphor-based LED efficiency losses are due to the heat loss from the Stokes shift and also other phosphor-related degradation issues. Their luminous efficacies compared to normal LEDs depend on the spectral distribution of the resultant light output and the original wavelength of the LED itself. For example, the luminous efficacy of a typical YAG yellow phosphor based white LED ranges from 3 to 5 times the luminous efficacy of the original blue LED because of the human eye's greater sensitivity to yellow than to blue (as modeled in the luminosity function). Due to the simplicity of manufacturing the phosphor method is still the most popular method for making high-intensity white LEDs. The design and production of a light source or light fixture using a monochrome emitter with phosphor conversion is simpler and cheaper than a complex RGB system, and the majority of high-intensity white LEDs presently on the market are manufactured using phosphor light conversion.

 Why is efficiency never lost in phosphor-based LEDs?

A: unanswerable


Problem: Somalis:

An estimated 20,000 Somalis emigrated to the U.S. state of Minnesota some ten years ago and the Twin Cities (Minneapolis and Saint Paul) now have the highest population of Somalis in North America. The city of Minneapolis hosts hundreds of Somali-owned and operated businesses offering a variety of products, including leather shoes, jewelry and other fashion items, halal meat, and hawala or money transfer services. Community-based video rental stores likewise carry the latest Somali films and music. The number of Somalis has especially surged in the Cedar-Riverside area of Minneapolis.

What is hawala?

A:
money transfer services
