Input: Avicenna
There are occasional brief hints and allusions in his longer works however that Avicenna considered philosophy as the only sensible way to distinguish real prophecy from illusion. He did not state this more clearly because of the political implications of such a theory, if prophecy could be questioned, and also because most of the time he was writing shorter works which concentrated on explaining his theories on philosophy and theology clearly, without digressing to consider epistemological matters which could only be properly considered by other philosophers.

What did Avicenna not consider when explaining his theories on philosophy?
Output: epistemological matters

Input: Article: The club's success in the late 1990s and first decade of the 21st century owed a great deal to the 1996 appointment of Arsene Wenger as manager. Wenger brought new tactics, a new training regime and several foreign players who complemented the existing English talent. Arsenal won a second League and Cup double in 199798 and a third in 200102. In addition, the club reached the final of the 19992000 UEFA Cup (losing on penalties to Galatasaray), were victorious in the 2003 and 2005 FA Cups, and won the Premier League in 200304 without losing a single match, an achievement which earned the side the nickname "The Invincibles". The feat came within a run of 49 league matches unbeaten from 7 May 2003 to 24 October 2004, a national record.

Now answer this question: Besides improved tactics and training, what did Wenger add to the Arsenal team?

Output: foreign players

Article: The U.S. Navy, by contrast, relied on commerce raiding from the outset. However, the problem of Allied forces surrounded in the Philippines, during the early part of 1942, led to diversion of boats to "guerrilla submarine" missions. As well, basing in Australia placed boats under Japanese aerial threat while en route to patrol areas, reducing their effectiveness, and Nimitz relied on submarines for close surveillance of enemy bases. Furthermore, the standard-issue Mark 14 torpedo and its Mark VI exploder both proved defective, problems which were not corrected until September 1943. Worst of all, before the war, an uninformed US Customs officer had seized a copy of the Japanese merchant marine code (called the "maru code" in the USN), not knowing that the Office of Naval Intelligence (ONI) had broken it. The Japanese promptly changed it, and the new code was not broken again by OP-20G until 1943.

Question: What did the US Navy rely on?
Ans: commerce raiding

Here is a question about this article: In Serbia, the Serbian language is the official one, while both Serbian and Croatian are official in the province of Vojvodina. A large Bosniak minority is present in the southwest region of Sandzak, but the "official recognition" of Bosnian language is moot. Bosnian is an optional course in 1st and 2nd grade of the elementary school, while it is also in official use in the municipality of Novi Pazar. However, its nomenclature is controversial, as there is incentive that it is referred to as "Bosniak" (bosnjacki) rather than "Bosnian" (bosanski) (see Bosnian language for details).
What is the answer to this question: To what should the language be referred to instead of "Bosnian"?
****
So... "Bosniak" (bosnjacki)

Article: The relative peace of the Tokugawa era was shattered with the arrival of Commodore Matthew Perry's massive U.S. Navy steamships in 1853. Perry used his superior firepower to force Japan to open its borders to trade. Prior to that only a few harbor towns, under strict control from the Shogunate, were allowed to participate in Western trade, and even then, it was based largely on the idea of playing the Franciscans and Dominicans off against one another (in exchange for the crucial arquebus technology, which in turn was a major contributor to the downfall of the classical samurai).

Question: Which force invaded Japan in 1853?
Ans:
U.S. Navy
