Input: Read this: Glass-ceramic materials share many properties with both non-crystalline glass and crystalline ceramics. They are formed as a glass, and then partially crystallized by heat treatment. For example, the microstructure of whiteware ceramics frequently contains both amorphous and crystalline phases. Crystalline grains are often embedded within a non-crystalline intergranular phase of grain boundaries. When applied to whiteware ceramics, vitreous means the material has an extremely low permeability to liquids, often but not always water, when determined by a specified test regime.
Question: What hardens glass-ceramics?

Output: heat treatment


QUES: One of the most important victories of the magnates was the late 16th century right to create ordynacja's (similar to majorats), which ensured that a family which gained wealth and power could more easily preserve this.

What was an important power basis for the magnates?
What is the answer?

Throughout most of his career, Athanasius had many detractors. Classical scholar Timothy Barnes relates contemporary allegations against Athanasius: from defiling an altar, to selling Church grain that had been meant to feed the poor for his own personal gain, and even violence and murder to suppress dissent. Athanasius used "Arian" to describe both followers of Arius, and as a derogatory polemical term for Christians who disagreed with his formulation of the Trinity. Athanasius called many of his opponents "Arian", except for Miletus.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): He was accused of selling grain for what reason?
Ah, so.. his own personal gain


Question: Conversely, DST can adversely affect farmers, parents of young children, and others whose hours are set by the sun and they have traditionally opposed the practice, although some farmers are neutral. One reason why farmers oppose DST is that grain is best harvested after dew evaporates, so when field hands arrive and leave earlier in summer their labor is less valuable. Dairy farmers are another group who complain of the change. Their cows are sensitive to the timing of milking, so delivering milk earlier disrupts their systems. Today some farmers' groups are in favor of DST.
Try to answer this question if possible: Besides farmers, what other group of people set their schedules by the sun?
Answer: parents of young children
