Input: Read this: The Polish scholar Jan Baudouin de Courtenay (together with his former student Mikołaj Kruszewski) introduced the concept of the phoneme in 1876, and his work, though often unacknowledged, is considered to be the starting point of modern phonology. He also worked on the theory of phonetic alternations (what is now called allophony and morphophonology), and had a significant influence on the work of Ferdinand de Saussure.
Question: What nationality was Kruszewski?

Output: unanswerable


QUES: In 1873, one of the first papers in modern medicine on the subject tried to explain the pathophysiology of the disease while one in 1872, concluded that asthma can be cured by rubbing the chest with chloroform liniment. Medical treatment in 1880, included the use of intravenous doses of a drug called pilocarpin. In 1886, F.H. Bosworth theorized a connection between asthma and hay fever. Epinephrine was first referred to in the treatment of asthma in 1905. Oral corticosteroids began to be used for this condition in the 1950s while inhaled corticosteroids and selective short acting beta agonist came into wide use in the 1960s.

When was the first paper written about asthma?
What is the answer?
ANS: In 1873


QUES: The fluid in the coelomata contains coelomocyte cells that defend the animals against parasites and infections. In some species coelomocytes may also contain a respiratory pigment – red hemoglobin in some species, green chlorocruorin in others (dissolved in the plasma) – and provide oxygen transport within their segments. Respiratory pigment is also dissolved in the blood plasma. Species with well-developed septa generally also have blood vessels running all long their bodies above and below the gut, the upper one carrying blood forwards while the lower one carries it backwards. Networks of capillaries in the body wall and around the gut transfer blood between the main blood vessels and to parts of the segment that need oxygen and nutrients. Both of the major vessels, especially the upper one, can pump blood by contracting. In some annelids the forward end of the upper blood vessel is enlarged with muscles to form a heart, while in the forward ends of many earthworms some of the vessels that connect the upper and lower main vessels function as hearts. Species with poorly developed or no septa generally have no blood vessels and rely on the circulation within the coelom for delivering nutrients and oxygen.
What type of pigment is created in annelids' blood?

ANS: unanswerable


FETs are divided into two families: junction FET (JFET) and insulated gate FET (IGFET). The IGFET is more commonly known as a metal–oxide–semiconductor FET (MOSFET), reflecting its original construction from layers of metal (the gate), oxide (the insulation), and semiconductor. Unlike IGFETs, the JFET gate forms a p–n diode with the channel which lies between the source and drain. Functionally, this makes the n-channel JFET the solid-state equivalent of the vacuum tube triode which, similarly, forms a diode between its grid and cathode. Also, both devices operate in the depletion mode, they both have a high input impedance, and they both conduct current under the control of an input voltage.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What controls the amount of input voltage?
Ah, so.. unanswerable


Question: The gas centrifuge process, where gaseous uranium hexafluoride (UF
6) is separated by the difference in molecular weight between 235UF6 and 238UF6 using high-speed centrifuges, is the cheapest and leading enrichment process. The gaseous diffusion process had been the leading method for enrichment and was used in the Manhattan Project. In this process, uranium hexafluoride is repeatedly diffused through a silver-zinc membrane, and the different isotopes of uranium are separated by diffusion rate (since uranium 238 is heavier it diffuses slightly slower than uranium-235). The molecular laser isotope separation method employs a laser beam of precise energy to sever the bond between uranium-235 and fluorine. This leaves uranium-238 bonded to fluorine and allows uranium-235 metal to precipitate from the solution. An alternative laser method of enrichment is known as atomic vapor laser isotope separation (AVLIS) and employs visible tunable lasers such as dye lasers. Another method used is liquid thermal diffusion.
Try to answer this question if possible: How does the height of uranium-238 compare to that of uranium-235?
Answer: unanswerable


Input: Read this: 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."
Question: Why did southern universities mostly award bachelor's degrees?
