Problem: Textual criticism:

Stemmatics, stemmology or stemmatology is a rigorous approach to textual criticism. Karl Lachmann (17931851) greatly contributed to making this method famous, even though he did not invent it. The method takes its name from the word stemma. The Ancient Greek word and its loanword in classical Latin stemmata may refer to "family trees". This specific meaning shows the relationships of the surviving witnesses (the first known example of such a stemma, albeit with the name, dates from 1827). The family tree is also referred to as a cladogram. The method works from the principle that "community of error implies community of origin." That is, if two witnesses have a number of errors in common, it may be presumed that they were derived from a common intermediate source, called a hyparchetype. Relations between the lost intermediates are determined by the same process, placing all extant manuscripts in a family tree or stemma codicum descended from a single archetype. The process of constructing the stemma is called recension, or the Latin recensio.

What is implied when two witnesses have a number of errors in common?
---
A: it may be presumed that they were derived from a common intermediate source

Problem: Political philosophy:

Western political philosophy originates in the philosophy of ancient Greece, where political philosophy dates back to at least Plato. Ancient Greece was dominated by city-states, which experimented with various forms of political organization, grouped by Plato into four categories: timocracy, tyranny, democracy and oligarchy. One of the first, extremely important classical works of political philosophy is Plato's Republic, which was followed by Aristotle's Nichomachean Ethics and Politics. Roman political philosophy was influenced by the Stoics, including the Roman statesman Cicero.

What philosophy dates back to sme time after Plato?
---
A: unanswerable

Problem: On the Origin of Species:

Page ii contains quotations by William Whewell and Francis Bacon on the theology of natural laws, harmonising science and religion in accordance with Isaac Newton's belief in a rational God who established a law-abiding cosmos. In the second edition, Darwin added an epigraph from Joseph Butler affirming that God could work through scientific laws as much as through miracles, in a nod to the religious concerns of his oldest friends. The Introduction establishes Darwin's credentials as a naturalist and author, then refers to John Herschel's letter suggesting that the origin of species "would be found to be a natural in contradistinction to a miraculous process":

Whose epigraph did Darwin add to On the Origin of Species harmonizing God with science and miracles together?
---
A: Joseph Butler

Problem: Seven Years%27 War:

Many middle and small powers in Europe, unlike in the previous wars, tried to steer clear away from the escalating conflict, even though they had interests in the conflict or with the belligerents, like Denmark-Norway. The Dutch Republic, long-time British ally, kept its neutrality intact, fearing the odds against Britain and Prussia fighting the great powers of Europe, even tried to prevent Britain's domination in India. Naples, Sicily, and Savoy, although sided with Franco-Spanish party, declined to join the coalition under the fear of British power. The taxation needed for war caused the Russian people considerable hardship, being added to the taxation of salt and alcohol begun by Empress Elizabeth in 1759 to complete her addition to the Winter Palace. Like Sweden, Russia concluded a separate peace with Prussia.

Which side of the coalitions did Naples, Sicily and Savoy join?
---
A:
Naples, Sicily, and Savoy, although sided with Franco-Spanish party, declined to join the coalition under the fear of British power
