Problem: Infection:

Another effective way to decrease the transmission rate of infectious diseases is to recognize the effects of small-world networks. In epidemics, there are often extensive interactions within hubs or groups of infected individuals and other interactions within discrete hubs of susceptible individuals. Despite the low interaction between discrete hubs, the disease can jump to and spread in a susceptible hub via a single or few interactions with an infected hub. Thus, infection rates in small-world networks can be reduced somewhat if interactions between individuals within infected hubs are eliminated (Figure 1). However, infection rates can be drastically reduced if the main focus is on the prevention of transmission jumps between hubs. The use of needle exchange programs in areas with a high density of drug users with HIV is an example of the successful implementation of this treatment method.  Another example is the use of ring culling or vaccination of potentially susceptible livestock in adjacent farms to prevent the spread of the foot-and-mouth virus in 2001.

When was vaccination used to prevent the spread of the foot-and-neck virus?

Problem: In February 1907, the Royal Dutch Shell Group was created through the amalgamation of two rival companies: the Royal Dutch Petroleum Company of the Netherlands and the "Shell" Transport and Trading Company Ltd of the United Kingdom. It was a move largely driven by the need to compete globally with Standard Oil. The Royal Dutch Petroleum Company was a Dutch company founded in 1890 to develop an oilfield in Sumatra, and initially led by August Kessler, Hugo Loudon, and Henri Deterding. The "Shell" Transport and Trading Company (the quotation marks were part of the legal name) was a British company, founded in 1897 by Marcus Samuel, 1st Viscount Bearsted, and his brother Samuel Samuel. Their father had owned an antique company in Houndsditch, London, which expanded in 1833 to import and sell sea-shells, after which the company "Shell" took its name.
Why was the Royal Dutch Petroleum Company created?

Critical and commercial reception to PS3 improved over time, after a series of price revisions, Blu-ray's victory over HD DVD, and the release of several well received titles. Ars Technica's original launch review gave PS3 only a 6/10, but second review of the console in June 2008 rated it a 9/10. In September 2009, IGN named PlayStation 3 the 15th best gaming console of all time, behind both of its competitors: Wii (10th) and Xbox 360 (6th). However, PS3 has won IGN's "Console Showdown"—based on which console offers the best selection of games released during each year—in three of the four years since it began (2008, 2009 and 2011, with Xbox winning in 2010). IGN judged PlayStation 3 to have the best game line-up of 2008, based on their review scores in comparison to those of Wii and Xbox 360. In a comparison piece by PC mag's Will Greenwald in June 2012, PS3 was selected as an overall better console compared to Xbox 360. Pocket-lint said of the console "The PS3 has always been a brilliant games console," and that "For now, this is just about the best media device for the money."
Which publication called the PlayStation 3 "a brilliant games console"?
A: Pocket-lint


Context and question: This nationwide acceptance and recognition of Aboriginal people led to a significant increase in the number of people self-identifying as Aboriginal or Torres Strait Islander. The reappropriation of the term "black" with a positive and more inclusive meaning has resulted in its widespread use in mainstream Australian culture, including public media outlets, government agencies, and private companies. In 2012, a number of high-profile cases highlighted the legal and community attitude that identifying as Aboriginal or Torres Strait Islander is not dependent on skin colour, with a well-known boxer Anthony Mundine being widely criticised for questioning the "blackness" of another boxer and journalist Andrew Bolt being successfully sued for publishing discriminatory comments about Aboriginals with light skin.
What well known boxer was criticized for question someone's blackness?
Answer: Anthony Mundine

Originally known as Buckingham House, the building at the core of today's palace was a large townhouse built for the Duke of Buckingham in 1703 on a site that had been in private ownership for at least 150 years. It was acquired by King George III in 1761 as a private residence for Queen Charlotte and became known as "The Queen's House". During the 19th century it was enlarged, principally by architects John Nash and Edward Blore, who constructed three wings around a central courtyard. Buckingham Palace became the London residence of the British monarch on the accession of Queen Victoria in 1837.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): For whom was Buckingham house originally built?
Ah, so..
Duke of Buckingham
