Problem: Zinc:

Brass, which is an alloy of copper and zinc, has been used since at least the 10th century BC in Judea and by the 7th century BC in Ancient Greece. Zinc metal was not produced on a large scale until the 12th century in India and was unknown to Europe until the end of the 16th century. The mines of Rajasthan have given definite evidence of zinc production going back to the 6th century BC. To date, the oldest evidence of pure zinc comes from Zawar, in Rajasthan, as early as the 9th century AD when a distillation process was employed to make pure zinc. Alchemists burned zinc in air to form what they called "philosopher's wool" or "white snow".

What two metals are mixed to create Brass?
---
A: copper and zinc

Problem: Athanasius of Alexandria:

Constantius, ordered Liberius into exile in 356 giving him, then, three days to comply. He was ordered into banishment to Beroea, in Thrace; Beroea (Thrace). He sent expensive presents, too, if he were to accept the Arian position but were refused. He sent him, indeed, five hundred pieces of gold "to bear his charges" but Liberius refused them, saying, he might bestow them on his flatters; as he did also a like present from the empress, bidding the messenger learn to believe in Christ, and not to persecute the Church of God. Attempts were made to leave the presents in The Church, but Liberius threw them out. Constantius hereupon sent for him under a strict guard to Milan, where, in a conference recorded by Theodoret, he boldly told Constantius that Athanasius had been acquitted at Sardica, and his enemies proved calumniators (see: "calumny") and impostors, and that it was unjust to condemn a person who could not be legally convicted of any crime. The emperor was reduced to silence on every article, but being the more out of patience, ordered him into banishment. Liberius went into exile. Constantius, after two years went to Rome to celebrate the twentieth year of his reign. The ladies joined in a petition to him that he would restore Liberius. He assented, upon condition that he should comply with the bishops, then, at court. He subscribed the condemnation of Athanasius, and a confession or creed which had been framed by the Arians at Sirmium. And he no sooner had recovered his see that he declared himself for the Creed of Niceae, as Theodoret testifies. (Theodoret, Hist. lib. ii. c. 17.). The Emperor knew what he wanted people to believe. So did the bishops at his court. Athanasius stuck by the orthodox creed. Constantius was an avowed Arian, became sole ruler in 350, at the death of his brother, Constans.

Who tried to bribe Liberius?
---
A: Constantius

Problem: Group (mathematics):

In the example above, the identity and the rotations constitute a subgroup R = {id, r1, r2, r3}, highlighted in red in the group table above: any two rotations composed are still a rotation, and a rotation can be undone by (i.e. is inverse to) the complementary rotations 270 for 90, 180 for 180, and 90 for 270 (note that rotation in the opposite direction is not defined). The subgroup test is a necessary and sufficient condition for a subset H of a group G to be a subgroup: it is sufficient to check that g1h H for all elements g, h H. Knowing the subgroups is important in understanding the group as a whole.d["]

What is defined when moving in the opposite direction?

A:
unanswerable
