Input: Antenna (radio)
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.

Buildings can create ghost images because of what?
Output: multipath propagation

Input: Article: Soteriologically, most Methodists are Arminian, emphasizing that Christ accomplished salvation for every human being, and that humans must exercise an act of the will to receive it (as opposed to the traditional Calvinist doctrine of monergism). Methodism is traditionally low church in liturgy, although this varies greatly between individual congregations; the Wesleys themselves greatly valued the Anglican liturgy and tradition. Methodism is known for its rich musical tradition; John Wesley's brother, Charles, was instrumental in writing much of the hymnody of the Methodist Church, and many other eminent hymn writers come from the Methodist tradition.

Now answer this question: What Calvinist doctrine is focuses on salvation?

Output: monergism

Article: In 1845, Ireland was hit by a potato blight. In the next four years over a million Irish people died and another million emigrated in what became known as the Great Famine. In Ireland, Victoria was labelled "The Famine Queen". She personally donated 2,000 to famine relief, more than any other individual donor, and also supported the Maynooth Grant to a Roman Catholic seminary in Ireland, despite Protestant opposition. The story that she donated only 5 in aid to the Irish, and on the same day gave the same amount to Battersea Dogs Home, was a myth generated towards the end of the 19th century.

Question: When did the potato blight begin?
Ans: 1845

Here is a question about this article: Philadelphia's central city was created in the 17th century following the plan by William Penn's surveyor Thomas Holme. Center City is structured with long straight streets running east-west and north-south forming a grid pattern. The original city plan was designed to allow for easy travel and to keep residences separated by open space that would help prevent the spread of fire. The Delaware River and Schuylkill Rivers served as early boundaries between which the city's early street plan was kept within. In addition, Penn planned the creation of five public parks in the city which were renamed in 1824 (in parenthesis): Centre Square, North East Publick Square (Franklin Square), Northwest Square (Logan Square), Southwest Square (Rittenhouse Square), and Southeast Square (Washington Square). Center City has grown into the second-most populated downtown area in the United States, after Midtown Manhattan in New York City, with an estimated 183,240 residents in 2015.
What is the answer to this question: How many live in the central area today?
****
So... 183,240

The problem: Answer a question about this article:
Matter should not be confused with mass, as the two are not quite the same in modern physics. For example, mass is a conserved quantity, which means that its value is unchanging through time, within closed systems. However, matter is not conserved in such systems, although this is not obvious in ordinary conditions on Earth, where matter is approximately conserved. Still, special relativity shows that matter may disappear by conversion into energy, even inside closed systems, and it can also be created from energy, within such systems. However, because mass (like energy) can neither be created nor destroyed, the quantity of mass and the quantity of energy remain the same during a transformation of matter (which represents a certain amount of energy) into non-material (i.e., non-matter) energy. This is also true in the reverse transformation of energy into matter.
What planet isn't a closed system but sometimes appears to be because of the approximate conservation of matter?
****
The answer: Earth

The problem: Answer a question about this article:
The city's municipal government was dominated by about 1215 merchant families, whose wealth came from overseas trade with continental Europe in particular the export of wool and hides and the import of salt, iron and wine. The medieval population of Cork was about 2,100 people. It suffered a severe blow in 1349 when almost half the townspeople died of plague when the Black Death arrived in the town. In 1491, Cork played a part in the English Wars of the Roses when Perkin Warbeck a pretender to the English throne, landed in the city and tried to recruit support for a plot to overthrow Henry VII of England. The then mayor of Cork and several important citizens went with Warbeck to England but when the rebellion collapsed they were all captured and executed. The title of Mayor of Cork was established by royal charter in 1318, and the title was changed to Lord Mayor in 1900 following the knighthood of the incumbent Mayor by Queen Victoria on her Royal visit to the city.
What caused the deaths of half of Cork's citizens?
****
The answer:
Black Death
