Input: Read this: Iron is usually found as iron ore on Earth, except for one deposit of native iron in Greenland, which was used by the Inuit people. Native copper, however, was found worldwide, along with silver, gold and platinum, which were also used to make tools, jewelry, and other objects since Neolithic times. Copper was the hardest of these metals, and the most widely distributed. It became one of the most important metals to the ancients. Eventually, humans learned to smelt metals such as copper and tin from ore, and, around 2500 BC, began alloying the two metals to form bronze, which is much harder than its ingredients. Tin was rare, however, being found mostly in Great Britain. In the Middle East, people began alloying copper with zinc to form brass. Ancient civilizations took into account the mixture and the various properties it produced, such as hardness, toughness and melting point, under various conditions of temperature and work hardening, developing much of the information contained in modern alloy phase diagrams. Arrowheads from the Chinese Qin dynasty (around 200 BC) were often constructed with a hard bronze-head, but a softer bronze-tang, combining the alloys to prevent both dulling and breaking during use.
Question: What did humans began alloying around 2500 A.D.?

Output: unanswerable

QUES: Another view, advanced by Richard Dawkins, is that the existence of God is an empirical question, on the grounds that "a universe with a god would be a completely different kind of universe from one without, and it would be a scientific difference." Carl Sagan argued that the doctrine of a Creator of the Universe was difficult to prove or disprove and that the only conceivable scientific discovery that could disprove the existence of a Creator would be the discovery that the universe is infinitely old.
How would the universe be different according to Carl Sagan?

ANS: unanswerable

A fervent follower of the absolutist cause, Elio had played an important role in the repression of the supporters of the Constitution of 1812. For this, he was arrested in 1820 and executed in 1822 by garroting. Conflict between absolutists and liberals continued, and in the period of conservative rule called the Ominous Decade (18231833), which followed the Trienio Liberal, there was ruthless repression by government forces and the Catholic Inquisition. The last victim of the Inquisition was Gaieta Ripoli, a teacher accused of being a deist and a Mason who was hanged in Valencia in 1824.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who helped repress the supporters of the Constitution and was later executed for it?
Ah, so.. Elio
