Problem: Age of Enlightenment:

In France, the established men of letters (gens de lettres) had fused with the elites (les grands) of French society by the mid-18th century. This led to the creation of an oppositional literary sphere, Grub Street, the domain of a "multitude of versifiers and would-be authors". These men came to London to become authors, only to discover that the literary market simply could not support large numbers of writers, who, in any case, were very poorly remunerated by the publishing-bookselling guilds.

Could the London market support the large numbers of writers that were emerging?

A: not

Problem: In Mark, Jesus is crucified along with two rebels, and the day goes dark for three hours. Jesus calls out to God, then gives a shout and dies. The curtain of the Temple is torn in two. Matthew follows Mark, adding an earthquake and the resurrection of saints. Luke also follows Mark, though he describes the rebels as common criminals, one of whom defends Jesus, who in turn promises that he (Jesus) and the criminal will be together in paradise. Luke portrays Jesus as impassive in the face of his crucifixion. John includes several of the same elements as those found in Mark, though they are treated differently.
How long were the two rebels hanging on crosses?

Criticism of the term intellectual property ranges from discussing its vagueness and abstract overreach to direct contention to the semantic validity of using words like property and rights in fashions that contradict practice and law. Many detractors think this term specially serves the doctrinal agenda of parties opposing reform in the public interest or otherwise abusing related legislations; and that it disallows intelligent discussion about specific and often unrelated aspects of copyright, patents, trademarks, etc.
Which term is criticized as having abstract overreach?
A: intellectual property

Context and question: Royal assent is the method by which a country's constitutional monarch (possibly through a delegated official) formally approves an act of that nation's parliament, thus making it a law or letting it be promulgated as law. In the vast majority of contemporary monarchies, this act is considered to be little more than a formality; even in those nations which still permit their ruler to withhold the royal assent (such as the United Kingdom, Norway, and Liechtenstein), the monarch almost never does so, save in a dire political emergency or upon the advice of their government. While the power to withhold royal assent was once exercised often in European monarchies, it is exceedingly rare in the modern, democratic political atmosphere that has developed there since the 18th century.
Since which century have modern political processes forgone royal assent?
Answer: 18th

Question: The spirituality evidenced throughout all of the branches of the order reflects the spirit and intentions of its founder, though some of the elements of what later developed might have surprised the Castilian friar.

It is that spirit which [Dominic] bequeathed to his followers".
Is there an answer to this question: What type of man was Dominic?

Answer: a man of prayer

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 is the percentage of stoke shift loss in YAG phosphor?
A:
less than 10%
