QUES: Victoria visited mainland Europe regularly for holidays. In 1889, during a stay in Biarritz, she became the first reigning monarch from Britain to set foot in Spain when she crossed the border for a brief visit. By April 1900, the Boer War was so unpopular in mainland Europe that her annual trip to France seemed inadvisable. Instead, the Queen went to Ireland for the first time since 1861, in part to acknowledge the contribution of Irish regiments to the South African war. In July, her second son Alfred ("Affie") died; "Oh, God! My poor darling Affie gone too", she wrote in her journal. "It is a horrible year, nothing but sadness & horrors of one kind & another."

Although each institution is organized differently, nearly all universities have a board of trustees; a president, chancellor, or rector; at least one vice president, vice-chancellor, or vice-rector; and deans of various divisions. Universities are generally divided into a number of academic departments, schools or faculties. Public university systems are ruled over by government-run higher education boards. They review financial requests and budget proposals and then allocate funds for each university in the system. They also approve new programs of instruction and cancel or make changes in existing programs. In addition, they plan for the further coordinated growth and development of the various institutions of higher education in the state or country. However, many public universities in the world have a considerable degree of financial, research and pedagogical autonomy. Private universities are privately funded and generally have broader independence from state policies. However, they may have less independence from business corporations depending on the source of their finances.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who controls public universities?
Ah, so.. government-run higher education boards


Question: 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".
Try to answer this question if possible: What two metals are mixed to create Brass?
