Input: Beer
The brewing industry is a global business, consisting of several dominant multinational companies and many thousands of smaller producers ranging from brewpubs to regional breweries. More than 133 billion litres (35 billion gallons) are sold per year—producing total global revenues of $294.5 billion (£147.7 billion) in 2006. The history of breweries has been one of absorbing smaller breweries in order to ensure economy of scale. In 2002 South African Breweries bought the North American Miller Brewing Company to found SABMiller, becoming the second largest brewery, after North American Anheuser-Bush. In 2004 the Belgian Interbrew was the third largest brewery by volume and the Brazilian AmBev was the fifth largest. They merged into InBev, becoming the largest brewery. In 2007, SABMiller surpassed InBev and Anheuser-Bush when it acquired Royal Grolsch, brewer of Dutch premium beer brand Grolsch in 2007. In 2008, InBev (the second-largest) bought Anheuser-Busch (the third largest), the new Anheuser-Busch InBev company became again the largest brewer in the world. As of 2015[update] AB InBev is the largest brewery, with SABMiller second, and Heineken International third.

Input: Article: Professional wrestling shows can be considered a form of theatre in the round, with the ring, ringside area, and entryway comprising a thrust stage. However, there is a much more limited concept of a fourth wall than in most theatric performances. The audience is recognized and acknowledged by the performers as spectators to the sporting event being portrayed, and are encouraged to interact as such. This leads to a high level of audience participation; in fact, their reactions can dictate how the performance unfolds. Often, individual matches will be part of a longer storyline conflict between "babyfaces" (often shortened to just "faces") and "heels". "Faces" (the "good guys") are those whose actions are intended to encourage the audience to cheer, while "heels" (the "bad guys") act to draw the spectators' ire.

Now answer this question: Which of the wrestlers are the bad guys?

Output: "heels" (the "bad guys")

Here is a question about this article: Somalis have a rich musical heritage centered on traditional Somali folklore. Most Somali songs are pentatonic. That is, they only use five pitches per octave in contrast to a heptatonic (seven note) scale, such as the major scale. At first listen, Somali music might be mistaken for the sounds of nearby regions such as Ethiopia, Sudan or Arabia, but it is ultimately recognizable by its own unique tunes and styles. Somali songs are usually the product of collaboration between lyricists (midho), songwriters (lahan) and singers ('odka or "voice").
What is the answer to this question: Along with Arabia and Ethiopia, what land has songs that sound similar to those of Somalia?
****
So... Sudan


The problem: Answer a question about this article:
Not all introduced species are invasive, nor all invasive species deliberately introduced. In cases such as the zebra mussel, invasion of US waterways was unintentional. In other cases, such as mongooses in Hawaii, the introduction is deliberate but ineffective (nocturnal rats were not vulnerable to the diurnal mongoose). In other cases, such as oil palms in Indonesia and Malaysia, the introduction produces substantial economic benefits, but the benefits are accompanied by costly unintended consequences.
What animal unintentionally invaded the US waterways?
****
The answer: the zebra mussel
