Input: Article: John Evans, for whom Evanston is named, bought 379 acres (153 ha) of land along Lake Michigan in 1853, and Philo Judson developed plans for what would become the city of Evanston, Illinois. The first building, Old College, opened on November 5, 1855. To raise funds for its construction, Northwestern sold $100 "perpetual scholarships" entitling the purchaser and his heirs to free tuition. Another building, University Hall, was built in 1869 of the same Joliet limestone as the Chicago Water Tower, also built in 1869, one of the few buildings in the heart of Chicago to survive the Great Chicago Fire of 1871. In 1873 the Evanston College for Ladies merged with Northwestern, and Frances Willard, who later gained fame as a suffragette and as one of the founders of the Woman's Christian Temperance Union (WCTU), became the school's first dean of women. Willard Residential College (1938) is named in her honor. Northwestern admitted its first women students in 1869, and the first woman was graduated in 1874.

Now answer this question: Who was Northwestern's first dean of women?

Output: Frances Willard

Article: Non-Muslim groups in the Umayyad Caliphate, which included Christians, Jews, Zoroastrians, and pagan Berbers, were called dhimmis. They were given a legally protected status as second-class citizens as long as they accepted and acknowledged the political supremacy of the ruling Muslims. They were allowed to have their own courts, and were given freedom of their religion within the empire.[citation needed] Although they could not hold the highest public offices in the empire, they had many bureaucratic positions within the government. Christians and Jews still continued to produce great theological thinkers within their communities, but as time wore on, many of the intellectuals converted to Islam, leading to a lack of great thinkers in the non-Muslim communities.

Question: Along with Berbers, Zoroastrians and Christians, what notable non-Muslim group existed in the Umayyad Caliphate?
Ans: Jews

Here is a question about this article: The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (CuFeS2) and to a lesser extent chalcocite (Cu2S). These minerals are concentrated from crushed ores to the level of 1015% copper by froth flotation or bioleaching. Heating this material with silica in flash smelting removes much of the iron as slag. The process exploits the greater ease of converting iron sulfides into its oxides, which in turn react with the silica to form the silicate slag, which floats on top of the heated mass. The resulting copper matte consisting of Cu2S is then roasted to convert all sulfides into oxides:
What is the answer to this question: What happens to the silicate slag during the flash smelting process?
****
So... floats on top
