Problem: Please answer a question about the following article about Late Middle Ages:
Bohemia prospered in the 14th century, and the Golden Bull of 1356 made the king of Bohemia first among the imperial electors, but the Hussite revolution threw the country into crisis. The Holy Roman Empire passed to the Habsburgs in 1438, where it remained until its dissolution in 1806. Yet in spite of the extensive territories held by the Habsburgs, the Empire itself remained fragmented, and much real power and influence lay with the individual principalities. In addition, financial institutions, such as the Hanseatic League and the Fugger family, held great power, on both economic and a political levels.
In what year was the Holy Roman Empire dissolved?
A: 1806

In 1999, the representatives of Lutheran World Federation and Catholic Church signed the Joint Declaration on the Doctrine of Justification, apparently resolving the conflict over the nature of justification which was at the root of the Protestant Reformation, although Confessional Lutherans reject this statement. This is understandable, since there is no compelling authority within them. On 18 July 2006, delegates to the World Methodist Conference voted unanimously to adopt the Joint Declaration.

Who adopted the Joint Declaration in 2006?
Answer: delegates to the World Methodist Conference

Problem: Historians estimate that between the advent of Islam in 650CE and the abolition of slavery in the Arabian Peninsula in the mid-20th century, 10 to 18 million sub-Saharan Black Africans were enslaved by Arab slave traders and transported to the Arabian Peninsula and neighboring countries. This number far exceeded the number of slaves who were taken to the Americas. Several factors affected the visibility of descendants of this diaspora in 21st-century Arab societies: The traders shipped more female slaves than males, as there was a demand for them to serve as concubines in harems in the Arabian Peninsula and neighboring countries. Male slaves were castrated in order to serve as harem guards. The death toll of Black African slaves from forced labor was high. The mixed-race children of female slaves and Arab owners were assimilated into the Arab owners' families under the patrilineal kinship system. As a result, few distinctive Afro-Arab black communities have survived in the Arabian Peninsula and neighboring countries.
Why were women slaves more popular?
The answer is the following: for them to serve as concubines

The team placed fifth in the Premier League automatically qualifies for the UEFA Europa League, and the sixth and seventh-placed teams can also qualify, depending on the winners of the two domestic cup competitions i.e. the FA Cup and the Capital One Cup (League Cup). Two Europa League places are reserved for the winners of each tournament; if the winner of either the FA Cup or League Cup qualifies for the Champions League, then that place will go to the next-best placed finisher in the Premier League. A further place in the UEFA Europa League is also available via the Fair Play initiative. If the Premier League has one of the three highest Fair Play rankings in Europe, the highest ranked team in the Premier League Fair Play standings which has not already qualified for Europe will automatically qualify for the UEFA Europa League first qualifying round.
To which league is the fifth place Premier League team automatically qualified for?
UEFA Europa League

Input: USB
By design, it is difficult to insert a USB plug into its receptacle incorrectly. The USB specification states that the required USB icon must be embossed on the "topside" of the USB plug, which "...provides easy user recognition and facilitates alignment during the mating process." The specification also shows that the "recommended" "Manufacturer's logo" ("engraved" on the diagram but not specified in the text) is on the opposite side of the USB icon. The specification further states, "The USB Icon is also located adjacent to each receptacle. Receptacles should be oriented to allow the icon on the plug to be visible during the mating process." However, the specification does not consider the height of the device compared to the eye level height of the user, so the side of the cable that is "visible" when mated to a computer on a desk can depend on whether the user is standing or kneeling.

Receptacles should be oriented to allow the icon on the plug to what?
Output: to be visible during the mating process

Problem: Please answer a question about the following article about United States dollar:
Early releases of the Washington coin included error coins shipped primarily from the Philadelphia mint to Florida and Tennessee banks. Highly sought after by collectors, and trading for as much as $850 each within a week of discovery, the error coins were identified by the absence of the edge impressions "E PLURIBUS UNUM IN GOD WE TRUST 2007 P". The mint of origin is generally accepted to be mostly Philadelphia, although identifying the source mint is impossible without opening a mint pack also containing marked units. Edge lettering is minted in both orientations with respect to "heads", some amateur collectors were initially duped into buying "upside down lettering error" coins. Some cynics also erroneously point out that the Federal Reserve makes more profit from dollar bills than dollar coins because they wear out in a few years, whereas coins are more permanent. The fallacy of this argument arises because new notes printed to replace worn out notes, which have been withdrawn from circulation, bring in no net revenue to the government to offset the costs of printing new notes and destroying the old ones. As most vending machines are incapable of making change in banknotes, they commonly accept only $1 bills, though a few will give change in dollar coins.
How much were error coins initially worth for collectors?
A:
profit
