Problem: Phonology:

An influential school of phonology in the interwar period was the Prague school. One of its leading members was Prince Nikolai Trubetzkoy, whose Grundzuge der Phonologie (Principles of Phonology), published posthumously in 1939, is among the most important works in the field from this period. Directly influenced by Baudouin de Courtenay, Trubetzkoy is considered the founder of morphophonology, although this concept had also been recognized by de Courtenay. Trubetzkoy also developed the concept of the archiphoneme. Another important figure in the Prague school was Roman Jakobson, who was one of the most prominent linguists of the 20th century.

Question: Robert Plutchik agreed with Ekman's biologically driven perspective but developed the "wheel of emotions", suggesting eight primary emotions grouped on a positive or negative basis: joy versus sadness; anger versus fear; trust versus disgust; and surprise versus anticipation. Some basic emotions can be modified to form complex emotions. The complex emotions could arise from cultural conditioning or association combined with the basic emotions. Alternatively, similar to the way primary colors combine, primary emotions could blend to form the full spectrum of human emotional experience. For example, interpersonal anger and disgust could blend to form contempt. Relationships exist between basic emotions, resulting in positive or negative influences.
Is there an answer to this question: What does Plutchik see as the negative equivalent of disgust?

Answer: unanswerable

QUES: "Junior" Laemmle persuaded his father to bring Universal up to date. He bought and built theaters, converted the studio to sound production, and made several forays into high-quality production. His early efforts included the critically mauled part-talkie version of Edna Ferber's novel Show Boat (1929), the lavish musical Broadway (1929) which included Technicolor sequences; and the first all-color musical feature (for Universal), King of Jazz (1930). The more serious All Quiet on the Western Front (1930), won its year's Best Picture Oscar.
