The problem: Answer a question about this article:
Jews also spread across Europe during the period. Communities were established in Germany and England in the 11th and 12th centuries, but Spanish Jews, long settled in Spain under the Muslims, came under Christian rule and increasing pressure to convert to Christianity. Most Jews were confined to the cities, as they were not allowed to own land or be peasants.[U] Besides the Jews, there were other non-Christians on the edges of Europepagan Slavs in Eastern Europe and Muslims in Southern Europe.
In what type of settlement did most Jews live?
****
The answer: cities

The problem: Answer a question about this article:
At the end of the 12th century, Europe was divided into a multitude of city states and kingdoms. The area encompassing modern Germany, southern Denmark, the Netherlands, Belgium, Luxembourg, Switzerland, Austria, Slovakia, Czech Republic and much of northern Italy (excluding Venice and Papal State) was nominally part of the Holy Roman Empire, but local rulers exercised considerable autonomy. France, Denmark, Poland, Hungary, Portugal, Scotland, Castile, Aragon, Navarre, Sicily and Cyprus were independent kingdoms, as was the Angevin Empire, whose Plantagenet kings ruled England and large domains in what was to become modern France. Norway came under the influence of England, while the other Scandinavian countries and Poland were influenced by trading contacts with the Hanseatic League. Angevin kings brought the Gothic tradition from France to Southern Italy, while Lusignan kings introduced French Gothic architecture to Cyprus.
What type of kings brought the Gothic style from France to Southern Italy?
****
The answer: Angevin kings

The problem: Answer a question about this article:
Although several companies each produce over a billion individually packaged (known as discrete) transistors every year, the vast majority of transistors are now produced in integrated circuits (often shortened to IC, microchips or simply chips), along with diodes, resistors, capacitors and other electronic components, to produce complete electronic circuits. A logic gate consists of up to about twenty transistors whereas an advanced microprocessor, as of 2009, can use as many as 3 billion transistors (MOSFETs). "About 60 million transistors were built in 2002 for [each] man, woman, and child on Earth."
How many individually packaged transistors are produced each year?
****
The answer: over a billion

On the other hand, classical (analog) television transmissions are usually horizontally polarized, because in urban areas buildings can reflect the electromagnetic waves and create ghost images due to multipath propagation. Using horizontal polarization, ghosting is reduced because the amount of reflection of electromagnetic waves in the p polarization (horizontal polarization off the side of a building) is generally less than s (vertical, in this case) polarization. Vertically polarized analog television has nevertheless been used in some rural areas. In digital terrestrial television such reflections are less problematic, due to robustness of binary transmissions and error correction.
What cause less problems in digital terrestrial television?
****
The answer:
Vertically polarized analog television
