Problem: Please answer a question about the following article about Apollo:
The etymology of the name is uncertain. The spelling (pronounced [a.pol.ln] in Classical Attic) had almost superseded all other forms by the beginning of the common era, but the Doric form Apellon (), is more archaic, derived from an earlier *j. It probably is a cognate to the Doric month Apellaios (), and the offerings apellaia () at the initiation of the young men during the family-festival apellai (). According to some scholars the words are derived from the Doric word apella (), which originally meant "wall," "fence for animals" and later "assembly within the limits of the square." Apella () is the name of the popular assembly in Sparta, corresponding to the ecclesia (). R. S. P. Beekes rejected the connection of the theonym with the noun apellai and suggested a Pre-Greek proto-form *Apalyun.
What is offered at the initiation of young men during familly-festival apellai?
A: apellaia

Among the challenges being faced to improve the efficiency of LED-based white light sources is the development of more efficient phosphors. As of 2010, the most efficient yellow phosphor is still the YAG phosphor, with less than 10% Stoke shift loss. Losses attributable to internal optical losses due to re-absorption in the LED chip and in the LED packaging itself account typically for another 10% to 30% of efficiency loss. Currently, in the area of phosphor LED development, much effort is being spent on optimizing these devices to higher light output and higher operation temperatures. For instance, the efficiency can be raised by adapting better package design or by using a more suitable type of phosphor. Conformal coating process is frequently used to address the issue of varying phosphor thickness.

What can improve the efficiency of LED-based white light?
Answer: more efficient phosphors

Problem: Throughout his presidency, Eisenhower adhered to a political philosophy of dynamic conservatism. A self-described "progressive conservative," he continued all the major New Deal programs still in operation, especially Social Security. He expanded its programs and rolled them into a new cabinet-level agency, the Department of Health, Education and Welfare, while extending benefits to an additional ten million workers. He implemented integration in the Armed Services in two years, which had not been completed under Truman.
How many people were added to the Social Security rolls by Eisenhower?
The answer is the following: ten million

Clovis the Frank, the first king of the Merovingian dynasty, made the city his capital from 508. A gradual immigration by the Franks also occurred in Paris in the beginning of the Frankish domination of Gaul which created the Parisian Francien dialects. Fortification of the Ile-de-France failed to prevent sacking by Vikings in 845 but Paris' strategic importancewith its bridges preventing ships from passingwas established by successful defence in the Siege of Paris (88586). In 987 Hugh Capet, Count of Paris (comte de Paris), Duke of the Franks (duc des Francs) was elected King of the Franks (roi des Franks). Under the rule of the Capetian kings, Paris gradually became the largest and most prosperous city in France.
In what year was Hugh Capet elected as king?
987

Input: Gothic architecture
At the Abbey Saint-Denis, Noyon Cathedral, Notre Dame de Paris and at the eastern end of Canterbury Cathedral in England, simple cylindrical columns predominate over the Gothic forms of clustered columns and shafted piers. Wells Cathedral in England, commenced at the eastern end in 1175, was the first building in which the designer broke free from Romanesque forms. The architect entirely dispensed with the round arch in favour of the pointed arch and with cylindrical columns in favour of piers composed of clusters of shafts which lead into the mouldings of the arches. The transepts and nave were continued by Adam Locke in the same style and completed in about 1230. The character of the building is entirely Gothic. Wells Cathedral is thus considered the first truly Gothic cathedral.

What is another cathedral in which simple cylindrical columns stand out more than the Gothic features?
Output: Notre Dame de Paris

Problem: Please answer a question about the following article about The Sun (United Kingdom):
Murdoch has responded to some of the arguments against the newspaper by saying that critics are "snobs" who want to "impose their tastes on everyone else", while MacKenzie claims the same critics are people who, if they ever had a "popular idea", would have to "go and lie down in a dark room for half an hour". Both have pointed to the huge commercial success of the Sun in this period and its establishment as Britain's top-selling newspaper, claiming that they are "giving the public what they want". This conclusion is disputed by critics. John Pilger has said that a late-1970s edition of the Daily Mirror, which replaced the usual celebrity and domestic political news items with an entire issue devoted to his own front-line reporting of the genocide in Pol Pot's Cambodia, not only outsold The Sun on the day it was issued but became the only edition of the Daily Mirror to ever sell every single copy issued throughout the country, something never achieved by The Sun.
What distinction does one single edition of The Daily Mirror hold?
A:
the only edition of the Daily Mirror to ever sell every single copy issued throughout the country
