Input: Read this: In 1957, she made a state visit to the United States, where she addressed the United Nations General Assembly on behalf of the Commonwealth. On the same tour, she opened the 23rd Canadian Parliament, becoming the first monarch of Canada to open a parliamentary session. Two years later, solely in her capacity as Queen of Canada, she revisited the United States and toured Canada. In 1961, she toured Cyprus, India, Pakistan, Nepal, and Iran. On a visit to Ghana the same year, she dismissed fears for her safety, even though her host, President Kwame Nkrumah, who had replaced her as head of state, was a target for assassins. Harold Macmillan wrote, "The Queen has been absolutely determined all through ... She is impatient of the attitude towards her to treat her as ... a film star ... She has indeed 'the heart and stomach of a man' ... She loves her duty and means to be a Queen." Before her tour through parts of Quebec in 1964, the press reported that extremists within the Quebec separatist movement were plotting Elizabeth's assassination. No attempt was made, but a riot did break out while she was in Montreal; the Queen's "calmness and courage in the face of the violence" was noted.

Input: Read this: Brahmi evolved into a multiplicity of Brahmic scripts, many of which were used to write Sanskrit. Roughly contemporary with the Brahmi, Kharosthi was used in the northwest of the subcontinent. Sometime between the fourth and eighth centuries, the Gupta script, derived from Brahmi, became prevalent. Around the eighth century, the Sarada script evolved out of the Gupta script. The latter was displaced in its turn by Devanagari in the 11th or 12th century, with intermediary stages such as the Siddham script. In East India, the Bengali alphabet, and, later, the Odia alphabet, were used.
Question: From what was Gupta derived?

Output: Brahmi

Input: Read this: The American bison is a large bovid which inhabited much of western North America prior to the 1800s, living on the prairies in large herds. However, the vast herds of bison attracted market hunters, who killed dozens of bison for their hides only, leaving the rest to rot. Thousands of these hunters quickly eliminated the bison herds, bringing the population from several million in the early 1800s to a few hundred by the 1880s. Conservation efforts have allowed the population to increase, but the bison remains near-threatened.
Question: How much did a bison hide cost in the 1800's?
