Input: Franco-Prussian War
The German states proclaimed their union as the German Empire under the Prussian king, Wilhelm I, uniting Germany as a nation-state. The Treaty of Frankfurt of 10 May 1871 gave Germany most of Alsace and some parts of Lorraine, which became the Imperial territory of Alsace-Lorraine (Reichsland Elsaß-Lothringen).The German conquest of France and the unification of Germany upset the European balance of power, that had existed since the Congress of Vienna in 1815 and Otto von Bismarck maintained great authority in international affairs for two decades. French determination to regain Alsace-Lorraine and fear of another Franco-German war, along with British apprehension about the balance of power, became factors in the causes of World War I.

What was the date of the Treaty of Frankfurt?
Output: 10 May 1871

Input: Kanye West
Having initially announced a new album entitled So Help Me God slated for a 2014 release, in March 2015 West announced that the album would instead be tentatively called SWISH. Later that month, West was awarded an honorary doctorate by the School of the Art Institute of Chicago for his contributions to music, fashion, and popular culture, officially making him an honorary DFA. The next month, West headlined at the Glastonbury Festival in the UK, despite a petition signed by almost 135,000 people against his appearance. At one point, he told the audience: "You are now watching the greatest living rock star on the planet." Media outlets, including social media sites such as Twitter, were sharply divided on his performance. NME stated, "The decision to book West for the slot has proved controversial since its announcement, and the show itself appeared to polarise both Glastonbury goers and those who tuned in to watch on their TVs." The publication added that "he's letting his music speak for and prove itself." The Guardian said that "his set has a potent ferocity – but there are gaps and stutters, and he cuts a strangely lone figure in front of the vast crowd."

What school awarded Kanye west an honorary doctorate?
Output: School of the Art Institute of Chicago

Input: Brain
Sleep involves great changes in brain activity. Until the 1950s it was generally believed that the brain essentially shuts off during sleep, but this is now known to be far from true; activity continues, but patterns become very different. There are two types of sleep: REM sleep (with dreaming) and NREM (non-REM, usually without dreaming) sleep, which repeat in slightly varying patterns throughout a sleep episode. Three broad types of distinct brain activity patterns can be measured: REM, light NREM and deep NREM. During deep NREM sleep, also called slow wave sleep, activity in the cortex takes the form of large synchronized waves, whereas in the waking state it is noisy and desynchronized. Levels of the neurotransmitters norepinephrine and serotonin drop during slow wave sleep, and fall almost to zero during REM sleep; levels of acetylcholine show the reverse pattern.

Slow wave sleep is also known as what?
Output: deep NREM sleep

Input: Samurai
Maintaining the household was the main duty of samurai women. This was especially crucial during early feudal Japan, when warrior husbands were often traveling abroad or engaged in clan battles. The wife, or okugatasama (meaning: one who remains in the home), was left to manage all household affairs, care for the children, and perhaps even defend the home forcibly. For this reason, many women of the samurai class were trained in wielding a polearm called a naginata or a special knife called the kaiken in an art called tantojutsu (lit. the skill of the knife), which they could use to protect their household, family, and honor if the need arose.

What did samurai wives' duties include when their husbands were away?
Output:
manage all household affairs, care for the children, and perhaps even defend the home forcibly
