Input: Middle Ages
Society throughout Europe was disturbed by the dislocations caused by the Black Death. Lands that had been marginally productive were abandoned, as the survivors were able to acquire more fertile areas. Although serfdom declined in Western Europe it became more common in Eastern Europe, as landlords imposed it on those of their tenants who had previously been free. Most peasants in Western Europe managed to change the work they had previously owed to their landlords into cash rents. The percentage of serfs amongst the peasantry declined from a high of 90 to closer to 50 per cent by the end of the period. Landlords also became more conscious of common interests with other landholders, and they joined together to extort privileges from their governments. Partly at the urging of landlords, governments attempted to legislate a return to the economic conditions that existed before the Black Death. Non-clergy became increasingly literate, and urban populations began to imitate the nobility's interest in chivalry.

In what part of Europe did serfdom increase in this period?
Output: Eastern

Input: Article: Resonant antennas are expected to be used around a particular resonant frequency; an antenna must therefore be built or ordered to match the frequency range of the intended application. A particular antenna design will present a particular feedpoint impedance. While this may affect the choice of an antenna, an antenna's impedance can also be adapted to the desired impedance level of a system using a matching network while maintaining the other characteristics (except for a possible loss of efficiency).

Now answer this question: How could an antenna be made to coordinate with the needed frequency?

Output: built or ordered

Article: What is known in Iranian linguistic history as the "Middle Iranian" era is thought to begin around the 4th century BCE lasting through the 9th century. Linguistically the Middle Iranian languages are conventionally classified into two main groups, Western and Eastern.

Question: When did the age of Middle Iranian come to a close?
Ans: 9th century

Here is a question about this article: The difference in the above factors for the case of =0 is the reason that most broadcasting (transmissions intended for the public) uses vertical polarization. For receivers near the ground, horizontally polarized transmissions suffer cancellation. For best reception the receiving antennas for these signals are likewise vertically polarized. In some applications where the receiving antenna must work in any position, as in mobile phones, the base station antennas use mixed polarization, such as linear polarization at an angle (with both vertical and horizontal components) or circular polarization.
What is the answer to this question: What type of programmin relies on vertical polarization?
****
So... broadcasting

On 23 April 2014, the U.S. Federal Communications Commission (FCC) was reported to be considering a new rule that will permit ISPs to offer content providers a faster track to send content, thus reversing their earlier net neutrality position. A possible solution to net neutrality concerns may be municipal broadband, according to Professor Susan Crawford, a legal and technology expert at Harvard Law School. On 15 May 2014, the FCC decided to consider two options regarding Internet services: first, permit fast and slow broadband lanes, thereby compromising net neutrality; and second, reclassify broadband as a telecommunication service, thereby preserving net neutrality. On 10 November 2014, President Barack Obama recommended that the FCC reclassify broadband Internet service as a telecommunications service in order to preserve net neutrality. On 16 January 2015, Republicans presented legislation, in the form of a U.S. Congress H.R. discussion draft bill, that makes concessions to net neutrality but prohibits the FCC from accomplishing the goal or enacting any further regulation affecting Internet service providers. On 31 January 2015, AP News reported that the FCC will present the notion of applying ("with some caveats") Title II (common carrier) of the Communications Act of 1934 to the internet in a vote expected on 26 February 2015. Adoption of this notion would reclassify internet service from one of information to one of the telecommunications and, according to Tom Wheeler, chairman of the FCC, ensure net neutrality. The FCC is expected to enforce net neutrality in its vote, according to the New York Times.
what may possibly be a solution to net neutrality concerns?

The answer: municipal broadband

The problem: Answer a question about this article:
During the 14th century in the northeastern part of the state nomad tribes by the name of Jornado hunted bison along the Rio Grande; they left numerous rock paintings throughout the northeastern part of the state. When the Spanish explorers reached this area they found their descendants, Suma and Manso tribes. In the southern part of the state, in a region known as Aridoamerica, Chichimeca people survived by hunting, gathering, and farming between AD 300 and 1300. The Chichimeca are the ancestors of the Tepehuan people.
The Chichimeca are the ancestors of what people?
****
The answer:
Tepehuan
