Input: Article: During the NES era, Nintendo maintained exclusive control over titles released for the systemthe company had to approve every game, each third-party developer could only release up to five games per year (but some third parties got around this by using different names, for example Konami's "Ultra Games" brand), those games could not be released on another console within two years, and Nintendo was the exclusive manufacturer and supplier of NES cartridges. However, competition from Sega's console brought an end to this practice; in 1991, Acclaim began releasing games for both platforms, with most of Nintendo's other licensees following suit over the next several years; Capcom (which licensed some games to Sega instead of producing them directly) and Square were the most notable holdouts.

Now answer this question: For how many years did Nintendo require exclusivity on NES games?

Output: two

Input: Article: Greek figural mosaics could have been copied or adapted paintings, a far more prestigious artform, and the style was enthusiastically adopted by the Romans so that large floor mosaics enriched the floors of Hellenistic villas and Roman dwellings from Britain to Dura-Europos. Most recorded names of Roman mosaic workers are Greek, suggesting they dominated high quality work across the empire; no doubt most ordinary craftsmen were slaves. Splendid mosaic floors are found in Roman villas across North Africa, in places such as Carthage, and can still be seen in the extensive collection in Bardo Museum in Tunis, Tunisia.

Now answer this question: Carthage and Tunisia are in what general area?

Output: North Africa

Input: Article: On May 20, 1971, his brother, Meinhard, died in a car accident. Meinhard had been drinking and was killed instantly. Schwarzenegger did not attend his funeral. Meinhard was due to marry Erika Knapp, and the couple had a three-year-old son, Patrick. Schwarzenegger would pay for Patrick's education and help him to emigrate to the United States. Gustav died the following year from a stroke. In Pumping Iron, Schwarzenegger claimed that he did not attend his father's funeral because he was training for a bodybuilding contest. Later, he and the film's producer said this story was taken from another bodybuilder for the purpose of showing the extremes that some would go to for their sport and to make Schwarzenegger's image more cold and machine-like in order to fan controversy for the film. Barbara Baker, his first serious girlfriend, has said he informed her of his father's death without emotion and that he never spoke of his brother. Over time, he has given at least three versions of why he was absent from his father's funeral.

Now answer this question: What caused Schwarzenegger's father Gustav's death?

Output:
stroke
