Problem: Cotton:

The era of manufactured fibers began with the development of rayon in France in the 1890s. Rayon is derived from a natural cellulose and cannot be considered synthetic, but requires extensive processing in a manufacturing process, and led the less expensive replacement of more naturally derived materials. A succession of new synthetic fibers were introduced by the chemicals industry in the following decades. Acetate in fiber form was developed in 1924. Nylon, the first fiber synthesized entirely from petrochemicals, was introduced as a sewing thread by DuPont in 1936, followed by DuPont's acrylic in 1944. Some garments were created from fabrics based on these fibers, such as women's hosiery from nylon, but it was not until the introduction of polyester into the fiber marketplace in the early 1950s that the market for cotton came under threat. The rapid uptake of polyester garments in the 1960s caused economic hardship in cotton-exporting economies, especially in Central American countries, such as Nicaragua, where cotton production had boomed tenfold between 1950 and 1965 with the advent of cheap chemical pesticides. Cotton production recovered in the 1970s, but crashed to pre-1960 levels in the early 1990s.

What type of industry produced a growing chain of synthetic fibers?

A: chemicals industry


Problem: The leading Cubist architects were Pavel Janák, Josef Gočár, Vlastislav Hofman, Emil Králíček and Josef Chochol. They worked mostly in Prague but also in other Bohemian towns. The best-known Cubist building is the House of the Black Madonna in the Old Town of Prague built in 1912 by Josef Gočár with the only Cubist café in the world, Grand Café Orient. Vlastislav Hofman built the entrance pavilions of Ďáblice Cemetery in 1912–1914, Josef Chochol designed several residential houses under Vyšehrad. A Cubist streetlamp has also been preserved near the Wenceslas Square, designed by Emil Králíček in 1912, who also built the Diamond House in the New Town of Prague around 1913.
Where is the House of the Black Madonna located? 
---
Answer: Old Town of Prague


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The rediscovery of Aristotle's works–more than 3000 pages of it would eventually be translated –fuelled a spirit of inquiry into natural processes that had already begun to emerge in the 12th century. Some scholars believe that these works represented one of the most important document discoveries in Western intellectual history. Richard Dales, for instance, calls the discovery of Aristotle's works "a turning point in the history of Western thought." After Aristotle re-emerged, a community of scholars, primarily communicating in Latin, accelerated the process and practice of attempting to reconcile the thoughts of Greek antiquity, and especially ideas related to understanding the natural world, with those of the church. The efforts of this "scholasticism" were focused on applying Aristotelian logic and thoughts about natural processes to biblical passages and attempting to prove the viability of those passages through reason. This became the primary mission of lecturers, and the expectation of students.
What is considered one of the most important discoveries in the world?
A: unanswerable


Context and question: By 1987, CBS was the only "big three" American TV network to have a co-owned record company. ABC had sold its record division to MCA Records in 1979, and in 1986, NBC's parent company RCA was sold to General Electric, who then sold off all other RCA units, including the record division (which was bought by Ariola Records, later known as BMG).
What label did ABC sell in 1979?
Answer: MCA Records


Question: In 1971, the United States Department of Health, Education, and Welfare approached Marvel Comics editor-in-chief Stan Lee to do a comic book story about drug abuse. Lee agreed and wrote a three-part Spider-Man story portraying drug use as dangerous and unglamorous. However, the industry's self-censorship board, the Comics Code Authority, refused to approve the story because of the presence of narcotics, deeming the context of the story irrelevant. Lee, with Goodman's approval, published the story regardless in The Amazing Spider-Man #96–98 (May–July 1971), without the Comics Code seal. The market reacted well to the storyline, and the CCA subsequently revised the Code the same year.
Is there an answer to this question: What comic book series did stories related to this issue appear in?

Answer: Spider-Man


Problem: Humanism:

The ad fontes principle also had many applications. The re-discovery of ancient manuscripts brought a more profound and accurate knowledge of ancient philosophical schools such as Epicureanism, and Neoplatonism, whose Pagan wisdom the humanists, like the Church fathers of old, tended, at least initially, to consider as deriving from divine revelation and thus adaptable to a life of Christian virtue. The line from a drama of Terence, Homo sum, humani nihil a me alienum puto (or with nil for nihil), meaning "I am a human being, I think nothing human alien to me", known since antiquity through the endorsement of Saint Augustine, gained renewed currency as epitomising the humanist attitude. The statement, in a play modeled or borrowed from a (now lost) Greek comedy by Menander, may have originated in a lighthearted vein – as a comic rationale for an old man's meddling – but it quickly became a proverb and throughout the ages was quoted with a deeper meaning, by Cicero and Saint Augustine, to name a few, and most notably by Seneca. Richard Bauman writes:

Who was the most influential supporter of the ideals of Terence?
---
A:
Saint Augustine
