Question: Passage: The Quran describes itself as "the discernment" (al-furqān), "the mother book" (umm al-kitāb), "the guide" (huda), "the wisdom" (hikmah), "the remembrance" (dhikr) and "the revelation" (tanzīl; something sent down, signifying the descent of an object from a higher place to lower place). Another term is al-kitāb (The Book), though it is also used in the Arabic language for other scriptures, such as the Torah and the Gospels. The adjective of "Quran" has multiple transliterations including "quranic", "koranic", and "qur'anic", or capitalised as "Qur'anic", "Koranic", and "Quranic". The term mus'haf ('written work') is often used to refer to particular Quranic manuscripts but is also used in the Quran to identify earlier revealed books. Other transliterations of "Quran" include "al-Coran", "Coran", "Kuran", and "al-Qurʼan".

Answer: Which term meaning "the mother book" doesn't the Quran apply to itself?


Question: Passage: Before the pact's announcement, Communists in the West denied that such a treaty would be signed. Future member of the Hollywood Ten Herbert Biberman denounced rumors as "Fascist propaganda". Earl Browder, head of the Communist Party USA, stated that "there is as much chance of agreement as of Earl Browder being elected president of the Chamber of Commerce." Beginning in September 1939, the Soviet Comintern suspended all anti-Nazi and anti-fascist propaganda, explaining that the war in Europe was a matter of capitalist states attacking each other for imperialist purposes. Western Communists acted accordingly; while before they supported protecting collective security, now they denounced Britain and France going to war.

Answer: Who wasn't part of Hollywood Ten?


Question: Passage: At this time, Hal B. Wallis, who had latterly worked as a major producer at Paramount, moved over to Universal, where he produced several films, among them a lavish version of Maxwell Anderson's Anne of the Thousand Days (1969), and the equally lavish Mary, Queen of Scots (1971). Though neither could claim to be a big financial hit, both films received Academy Award nominations, and Anne was nominated for Best Picture, Best Actor (Richard Burton), Best Actress (Geneviève Bujold), and Best Supporting Actor (Anthony Quayle). Wallis retired from Universal after making the film Rooster Cogburn (1975), a sequel to True Grit (1969), which Wallis had produced at Paramount. Rooster Cogburn co-starred John Wayne, reprising his Oscar-winning role from the earlier film, and Katharine Hepburn, their only film together. The film was only a moderate success.

Answer:
What company did B. Hal Wallis work at before Universal?
