Problem: Alloy:

Alloys are often made to alter the mechanical properties of the base metal, to induce hardness, toughness, ductility, or other desired properties. Most metals and alloys can be work hardened by creating defects in their crystal structure. These defects are created during plastic deformation, such as hammering or bending, and are permanent unless the metal is recrystallized. However, some alloys can also have their properties altered by heat treatment. Nearly all metals can be softened by annealing, which recrystallizes the alloy and repairs the defects, but not as many can be hardened by controlled heating and cooling. Many alloys of aluminium, copper, magnesium, titanium, and nickel can be strengthened to some degree by some method of heat treatment, but few respond to this to the same degree that steel does.

What does recrystalization make permanent?

A: unanswerable

Problem: Kievan Rus' also played an important genealogical role in European politics. Yaroslav the Wise, whose stepmother belonged to the Macedonian dynasty, the greatest one to rule Byzantium, married the only legitimate daughter of the king who Christianized Sweden. His daughters became queens of Hungary, France and Norway, his sons married the daughters of a Polish king and a Byzantine emperor (not to mention a niece of the Pope), while his granddaughters were a German Empress and (according to one theory) the queen of Scotland. A grandson married the only daughter of the last Anglo-Saxon king of England. Thus the Rurikids were a well-connected royal family of the time.
Who did Yaroslav's sons marry?
---
Answer: daughters of a Polish king and a Byzantine emperor

Context and question: Memorization is a method of learning that allows an individual to recall information verbatim. Rote learning is the method most often used. Methods of memorizing things have been the subject of much discussion over the years with some writers, such as Cosmos Rossellius using visual alphabets. The spacing effect shows that an individual is more likely to remember a list of items when rehearsal is spaced over an extended period of time. In contrast to this is cramming: an intensive memorization in a short period of time. Also relevant is the Zeigarnik effect which states that people remember uncompleted or interrupted tasks better than completed ones. The so-called Method of loci uses spatial memory to memorize non-spatial information.
What learning tool did Cosmo Kramer write about?
Answer: unanswerable

Question: In 1744, Burke started at Trinity College Dublin, a Protestant establishment, which up until 1793, did not permit Catholics to take degrees. In 1747, he set up a debating society, "Edmund Burke's Club", which, in 1770, merged with TCD's Historical Club to form the College Historical Society; it is the oldest undergraduate society in the world. The minutes of the meetings of Burke's Club remain in the collection of the Historical Society. Burke graduated from Trinity in 1748. Burke's father wanted him to read Law, and with this in mind he went to London in 1750, where he entered the Middle Temple, before soon giving up legal study to travel in Continental Europe. After eschewing the Law, he pursued a livelihood through writing.
Is there an answer to this question: Who did Edmund Burke's Club split from?

Answer: unanswerable

Question: The high points of this cultural creativity are magnificent architecture, sculpture, and painting. The Gupta period produced scholars such as Kalidasa, Aryabhata, Varahamihira, Vishnu Sharma, and Vatsyayana who made great advancements in many academic fields. The Gupta period marked a watershed of Indian culture: the Guptas performed Vedic sacrifices to legitimize their rule, but they also patronized Buddhism, which continued to provide an alternative to Brahmanical orthodoxy. The military exploits of the first three rulers Chandragupta I, Samudragupta, and Chandragupta II - brought much of India under their leadership. Science and political administration reached new heights during the Gupta era. Strong trade ties also made the region an important cultural centre and established it as a base that would influence nearby kingdoms and regions in Burma, Sri Lanka, Maritime Southeast Asia, and Indochina. For these reasons, historian Dr.Barnett remarked:
Is there an answer to this question: Besides the Vedic practices, what other religion did the Guptas patronize?

Answer:
Buddhism
