Problem: Late Middle Ages:

The predominant school of thought in the 13th century was the Thomistic reconciliation of the teachings of Aristotle with Christian theology. The Condemnation of 1277, enacted at the University of Paris, placed restrictions on ideas that could be interpreted as heretical; restrictions that had implication for Aristotelian thought. An alternative was presented by William of Ockham, who insisted that the world of reason and the world of faith had to be kept apart. Ockham introduced the principle of parsimony – or Occam's razor – whereby a simple theory is preferred to a more complex one, and speculation on unobservable phenomena is avoided.

Which philosopher believed that reason and faith were to be kept together?

A: unanswerable


Problem: Printed circuit board:

At the glass transition temperature the resin in the composite softens and significantly increases thermal expansion; exceeding Tg then exerts mechanical overload on the board components - e.g. the joints and the vias. Below Tg the thermal expansion of the resin roughly matches copper and glass, above it gets significantly higher. As the reinforcement and copper confine the board along the plane, virtually all volume expansion projects to the thickness and stresses the plated-through holes. Repeated soldering or other exposition to higher temperatures can cause failure of the plating, especially with thicker boards; thick boards therefore require high Tg matrix.

Thin boards require high what?

A: unanswerable


Problem: Samurai:

By the end of the 12th century, samurai became almost entirely synonymous with bushi, and the word was closely associated with the middle and upper echelons of the warrior class. The samurai were usually associated with a clan and their lord, were trained as officers in military tactics and grand strategy, and they followed a set of rules that later came to be known as the bushidō. While the samurai numbered less than 10% of then Japan's population, their teachings can still be found today in both everyday life and in modern Japanese martial arts.

What did samurai mean nearly the same thing as?
---
A: bushi


Problem: Athanasius of Alexandria:

Pope Julius had died in April, 352, and was succeeded by Liberius. For two years Liberius had been favourable to the cause of Athanasius; but driven at last into exile, he was induced to sign an ambiguous formula, from which the great Nicene text, the "homoousion", had been studiously omitted. In 355 a council was held at Milan, where in spite of the vigorous opposition of a handful of loyal prelates among the Western bishops, a fourth condemnation of Athanasius was announced to the world. With his friends scattered, the saintly Hosius in exile, and Pope Liberius denounced as acquiescing in Arian formularies, Athanasius could hardly hope to escape. On the night of 8 February, 356, while engaged in services in the Church of St. Thomas, a band of armed men burst in to secure his arrest. It was the beginning of his third exile.

Did Liberius sympathize with Athanasius?

A:
Liberius had been favourable
