Problem: University:

The university culture developed differently in northern Europe than it did in the south, although the northern (primarily Germany, France and Great Britain) and southern universities (primarily Italy) did have many elements in common. Latin was the language of the university, used for all texts, lectures, disputations and examinations. Professors lectured on the books of Aristotle for logic, natural philosophy, and metaphysics; while Hippocrates, Galen, and Avicenna were used for medicine. Outside of these commonalities, great differences separated north and south, primarily in subject matter. Italian universities focused on law and medicine, while the northern universities focused on the arts and theology. There were distinct differences in the quality of instruction in these areas which were congruent with their focus, so scholars would travel north or south based on their interests and means. There was also a difference in the types of degrees awarded at these universities. English, French and German universities usually awarded bachelor's degrees, with the exception of degrees in theology, for which the doctorate was more common. Italian universities awarded primarily doctorates. The distinction can be attributed to the intent of the degree holder after graduation in the north the focus tended to be on acquiring teaching positions, while in the south students often went on to professional positions. The structure of northern universities tended to be modeled after the system of faculty governance developed at the University of Paris. Southern universities tended to be patterned after the student-controlled model begun at the University of Bologna. Among the southern universities, a further distinction has been noted between those of northern Italy, which followed the pattern of Bologna as a "self-regulating, independent corporation of scholars" and those of southern Italy and Iberia, which were "founded by royal and imperial charter to serve the needs of government."

What type of degree was given out at the University of Bolonga?

Problem: Zinc(I) compounds are rare, and require bulky ligands to stabilize the low oxidation state. Most zinc(I) compounds contain formally the [Zn2]2+ core, which is analogous to the [Hg2]2+ dimeric cation present in mercury(I) compounds. The diamagnetic nature of the ion confirms its dimeric structure. The first zinc(I) compound containing the ZnZn bond, (5-C5Me5)2Zn2, is also the first dimetallocene. The [Zn2]2+ ion rapidly disproportionates into zinc metal and zinc(II), and has only been obtained as a yellow glass formed by cooling a solution of metallic zinc in molten ZnCl2.
When a solution of metallic zinc is heated in molten ZnCl2, what is formed?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Hot 100 and Easy Listening charts became more similar again toward the end of the 1960s and into the early and mid-1970s, when the texture of much of the music played on Top 40 radio once more began to soften. The adult contemporary format began evolving into the sound that later defined it, with rock-oriented acts as Chicago, The Eagles, and Elton John becoming associated with the format.
During the middle and early parts of what decade did the similarity of Easy Listening and Hot 100 increase?
A: 1970s

Context and question: As African states became independent in the 1960s, the Soviet Union offered many of their citizens the chance to study in Russia. Over a period of 40 years, about 400,000 African students from various countries moved to Russia to pursue higher studies, including many Black Africans. This extended beyond the Soviet Union to many countries of the Eastern bloc.
How many students moved from Africa to Russia?
Answer: about 400,000

Question: During the late 19th century, several Gilded Age mansions reflecting the wealth of industry and shipping magnates were built east and west of the current downtown, along the major avenues of the Woodward plan. Most notable among them was the David Whitney House located at 4421 Woodward Avenue, which became a prime location for mansions. During this period some referred to Detroit as the Paris of the West for its architecture, grand avenues in the Paris style, and for Washington Boulevard, recently electrified by Thomas Edison. The city had grown steadily from the 1830s with the rise of shipping, shipbuilding, and manufacturing industries. Strategically located along the Great Lakes waterway, Detroit emerged as a major port and transportation hub.
Is there an answer to this question: Which street became known for it's mansions?

Answer: Woodward Avenue

QUES: Infrared tracking, also known as infrared homing, refers to a passive missile guidance system, which uses the emission from a target of electromagnetic radiation in the infrared part of the spectrum to track it. Missiles that use infrared seeking are often referred to as "heat-seekers", since infrared (IR) is just below the visible spectrum of light in frequency and is radiated strongly by hot bodies. Many objects such as people, vehicle engines, and aircraft generate and retain heat, and as such, are especially visible in the infrared wavelengths of light compared to objects in the background.

What is the term that uses the infrared spectrum that is radiated by hot bodies?
