Input: Somalis
Civil strife in the early 1990s greatly increased the size of the Somali diaspora, as many of the best educated Somalis left for the Middle East, Europe and North America. In Canada, the cities of Toronto, Ottawa, Calgary, Edmonton, Montreal, Vancouver, Winnipeg and Hamilton all harbor Somali populations. Statistics Canada's 2006 census ranks people of Somali descent as the 69th largest ethnic group in Canada.

What led to an increase in the number of Somalis leaving the country?
Output: Civil strife


Input: Article: Both AC-3 and DTS surround audio were clumsily implemented on LaserDiscs, leading to some interesting player- and disc-dependent issues. A disc that included AC-3 audio forfeited the right analog audio channel to the modulated AC-3 RF stream. If the player did not have an AC-3 output available, the next most attractive playback option would be the digital Dolby Surround or stereo audio tracks. The reason for this is the RF signal needs to bypass the audio circuitry in order to be properly processed by the demodulator. If either the player did not support digital audio tracks (common in older players), or the disc did not include digital audio tracks at all (uncommon for a disc which is mastered with an AC-3 track), the only remaining option was to fall back to a monophonic presentation of the left analog audio track. However, many older analog-only players not only failed to output AC-3 streams correctly, but were not even aware of their potential existence. Such a player will happily play the analog audio tracks verbatim, resulting in garbage (static) output in the right channel.

Now answer this question: Which channel would not work in conjunction with AC-3 audio?

Output: right analog audio channel


Article: Part of the Russian resistance was credited[by whom?] to the deployment of newly invented blockade mines. Perhaps the most influential contributor to the development of naval mining was a Swede resident in Russia, the inventor and civil engineer Immanuel Nobel (the father of Alfred Nobel). Immanuel Nobel helped the Russian war effort by applying his knowledge of industrial explosives, such as nitroglycerin and gunpowder. One account dates modern naval mining from the Crimean War: "Torpedo mines, if I may use this name given by Fulton to self-acting mines underwater, were among the novelties attempted by the Russians in their defences about Cronstadt and Sevastopol", as one American officer put it in 1860.

Question: What greatly benefited the Russian resistance?
Ans: newly invented blockade mines


Here is a question about this article: The sales breakdown of the Macintosh have seen sales of desktop Macs stayed mostly constant while being surpassed by that of Mac notebooks whose sales rate has grown considerably; seven out of ten Macs sold were laptops in 2009, a ratio projected to rise to three out of four by 2010. The change in sales of form factors is due to the desktop iMac moving from affordable (iMac G3) to upscale (iMac G4) and subsequent releases are considered premium all-in-ones. By contrast the MSRP of the MacBook laptop lines have dropped through successive generations such that the MacBook Air and MacBook Pro constitute the lowest price of entry to a Mac, with the exception of the even more inexpensive Mac Mini (the only sub-$1000 offering from Apple, albeit without a monitor and keyboard), not surprisingly the MacBooks are the top-selling form factors of the Macintosh platform today. The use of Intel microprocessors has helped Macs more directly compete with their Windows counterparts on price and performance, and by the 2010s Apple was receiving Intel's latest CPUs first before other PC manufacturers.
What is the answer to this question: What is the name of the most inexpensive Mac offered?
****
So... Mac Mini


The problem: Answer a question about this article:
Somerset is an important supplier of defence equipment and technology. A Royal Ordnance Factory, ROF Bridgwater was built at the start of the Second World War, between the villages of Puriton and Woolavington, to manufacture explosives. The site was decommissioned and closed in July 2008. Templecombe has Thales Underwater Systems, and Taunton presently has the United Kingdom Hydrographic Office and Avimo, which became part of Thales Optics. It has been announced twice, in 2006 and 2007, that manufacturing is to end at Thales Optics' Taunton site, but the trade unions and Taunton Deane District Council are working to reverse or mitigate these decisions. Other high-technology companies include the optics company Gooch and Housego, at Ilminster. There are Ministry of Defence offices in Bath, and Norton Fitzwarren is the home of 40 Commando Royal Marines. The Royal Naval Air Station in Yeovilton, is one of Britain's two active Fleet Air Arm bases and is home to the Royal Navy's Lynx helicopters and the Royal Marines Commando Westland Sea Kings. Around 1,675 service and 2,000 civilian personnel are stationed at Yeovilton and key activities include training of aircrew and engineers and the Royal Navy's Fighter Controllers and surface-based aircraft controllers.

The problem: Answer a question about this article:
The BCG vaccine has limitations, and research to develop new TB vaccines is ongoing. A number of potential candidates are currently in phase I and II clinical trials. Two main approaches are being used to attempt to improve the efficacy of available vaccines. One approach involves adding a subunit vaccine to BCG, while the other strategy is attempting to create new and better live vaccines. MVA85A, an example of a subunit vaccine, currently in trials in South Africa, is based on a genetically modified vaccinia virus. Vaccines are hoped to play a significant role in treatment of both latent and active disease.
What does one option propose adding to the existing BCG vaccine? 
****
The answer:
subunit vaccine
