Problem: Whitehead and Russell had thought originally that Principia Mathematica would take a year to complete; it ended up taking them ten years. To add insult to injury, when it came time for publication, the three-volume work was so massive (more than 2,000 pages) and its audience so narrow (professional mathematicians) that it was initially published at a loss of 600 pounds, 300 of which was paid by Cambridge University Press, 200 by the Royal Society of London, and 50 apiece by Whitehead and Russell themselves. Despite the initial loss, today there is likely no major academic library in the world which does not hold a copy of Principia Mathematica.
Who paid to publish Principia Mathematica?
The answer is the following: Cambridge University Press


The mosaics of the Villa Romana del Casale near Piazza Armerina in Sicily are the largest collection of late Roman mosaics in situ in the world, and are protected as a UNESCO World Heritage Site. The large villa rustica, which was probably owned by Emperor Maximian, was built largely in the early 4th century. The mosaics were covered and protected for 700 years by a landslide that occurred in the 12th Century. The most important pieces are the Circus Scene, the 64m long Great Hunting Scene, the Little Hunt, the Labours of Hercules and the famous Bikini Girls, showing women undertaking a range of sporting activities in garments that resemble 20th Century bikinis. The peristyle, the imperial apartments and the thermae were also decorated with ornamental and mythological mosaics. Other important examples of Roman mosaic art in Sicily were unearthed on the Piazza Vittoria in Palermo where two houses were discovered. The most important scenes there depicted Orpheus, Alexander the Great's Hunt and the Four Seasons.
What caused the mosaics at the villa rustica to be protected for centuries? 
a landslide


Input: European Central Bank
The independence of the ECB is instrumental in maintaining price stability. Not only must the bank not seek influence, but EU institutions and national governments are bound by the treaties to respect the ECB's independence. To offer some accountability, the ECB is bound to publish reports on its activities and has to address its annual report to the European Parliament, the European Commission, the Council of the European Union and the European Council. The European Parliament also gets to question and then issue its opinion on candidates to the executive board.

WHat is the biggest factor in the ECB maintaining price stability?
Output: independence


Input: Article: The first PCBs used through-hole technology, mounting electronic components by leads inserted through holes on one side of the board and soldered onto copper traces on the other side. Boards may be single-sided, with an unplated component side, or more compact double-sided boards, with components soldered on both sides. Horizontal installation of through-hole parts with two axial leads (such as resistors, capacitors, and diodes) is done by bending the leads 90 degrees in the same direction, inserting the part in the board (often bending leads located on the back of the board in opposite directions to improve the part's mechanical strength), soldering the leads, and trimming off the ends. Leads may be soldered either manually or by a wave soldering machine.

Now answer this question: Which type of PCB construction technique was used first?

Output: through-hole


Article: The staple products of Samoa are copra (dried coconut meat), cocoa bean (for chocolate), and bananas. The annual production of both bananas and copra has been in the range of 13,000 to 15,000 metric tons (about 14,500 to 16,500 short tons). If the rhinoceros beetle in Samoa were eradicated, Samoa could produce in excess of 40,000 metric tons (44,000 short tons) of copra. Samoan cocoa beans are of very high quality and used in fine New Zealand chocolates. Most are Criollo-Forastero hybrids. Coffee grows well, but production has been uneven. WSTEC is the biggest coffee producer. Rubber has been produced in Samoa for many years, but its export value has little impact on the economy.[citation needed]

Question: How many metric tons of bananas and copra does Samoa produce each year?
Ans: 13,000 to 15,000


Input: Mexico City
The Legislative Assembly of the Federal District is formed, as it is the case in all legislatures in Mexico, by both single-seat and proportional seats, making it a system of parallel voting. The Federal District is divided into 40 electoral constituencies of similar population which elect one representative by first-past-the-post plurality (FPP), locally called "uninominal deputies". The Federal District as a whole constitutes a single constituency for the parallel election of 26 representatives by proportionality (PR) with open-party lists, locally called "plurinominal deputies".

What is the local government of Mexico City called?
Output:
The Legislative Assembly of the Federal District
