Problem: Antibiotics:

In 1939, coinciding with the start of World War II, Rene Dubos reported the discovery of the first naturally derived antibiotic, tyrothricin, a compound of 20% gramicidin and 80% tyrocidine, from B. brevis. It was one of the first commercially manufactured antibiotics universally and was very effective in treating wounds and ulcers during World War II. Gramicidin, however, could not be used systemically because of toxicity. Tyrocidine also proved too toxic for systemic usage. Research results obtained during that period were not shared between the Axis and the Allied powers during the war.

When was tyrothricin created?

A: 1939

Problem: In 1609, while still there, Smyth wrote a tract titled "The Character of the Beast," or "The False Constitution of the Church." In it he expressed two propositions: first, infants are not to be baptized; and second, "Antichristians converted are to be admitted into the true Church by baptism." Hence, his conviction was that a scriptural church should consist only of regenerate believers who have been baptized on a personal confession of faith. He rejected the Separatist movement's doctrine of infant baptism (paedobaptism). Shortly thereafter, Smyth left the group, and layman Thomas Helwys took over the leadership, leading the church back to England in 1611. Ultimately, Smyth became committed to believers' baptism as the only biblical baptism. He was convinced on the basis of his interpretation of Scripture that infants would not be damned should they die in infancy.
What was his first proposition?

Answer: infants are not to be baptized

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Several political figures who served as Zhejiang's top political office of Communist Party Secretary have played key roles in various events in PRC history. Tan Zhenlin (term 1949-1952), the inaugural Party Secretary, was one of the leading voices against Mao's Cultural Revolution during the so-called February Countercurrent of 1967. Jiang Hua (term 1956-1968), was the "chief justice" on the Special Court in the case against the Gang of Four in 1980. Three provincial Party Secretaries since the 1990s have gone onto prominence at the national level. They include CPC General Secretary and President Xi Jinping (term 2002-2007), National People's Congress Chairman and former Vice-Premier Zhang Dejiang (term 1998-2002), and Zhao Hongzhu (term 2007-2012), the Deputy Secretary of the Central Commission for Discipline Inspection, China's top anti-corruption body. Of Zhejiang's fourteen Party Secretaries since 1949, none were native to the province.
When was the case against the Gang of Four?
A: 1980

Context and question: A hunter-gatherer is a human living in a society in which most or all food is obtained by foraging (collecting wild plants and pursuing wild animals), in contrast to agricultural societies, which rely mainly on domesticated species.

Question: In 1988, the civil rights leader Jesse Jackson urged Americans to use instead the term "African American" because it had a historical cultural base and was a construction similar to terms used by European descendants, such as German American, Italian American, etc. Since then, African American and black have often had parallel status. However, controversy continues over which if any of the two terms is more appropriate. Maulana Karenga argues that the term African-American is more appropriate because it accurately articulates their geographical and historical origin.[citation needed] Others have argued that "black" is a better term because "African" suggests foreignness, although Black Americans helped found the United States. Still others believe that the term black is inaccurate because African Americans have a variety of skin tones. Some surveys suggest that the majority of Black Americans have no preference for "African American" or "Black", although they have a slight preference for "black" in personal settings and "African American" in more formal settings.
Is there an answer to this question: Who argued for Americans to use the term "African American"?

Answer: Jesse Jackson

Question: In 1948, the point-contact transistor was independently invented by German physicists Herbert Matare and Heinrich Welker while working at the Compagnie des Freins et Signaux, a Westinghouse subsidiary located in Paris. Matare had previous experience in developing crystal rectifiers from silicon and germanium in the German radar effort during World War II. Using this knowledge, he began researching the phenomenon of "interference" in 1947. By June 1948, witnessing currents flowing through point-contacts, Matare produced consistent results using samples of germanium produced by Welker, similar to what Bardeen and Brattain had accomplished earlier in December 1947. Realizing that Bell Labs' scientists had already invented the transistor before them, the company rushed to get its "transistron" into production for amplified use in France's telephone network.
Is there an answer to this question: Who invented the point-contact transistor?

Answer:
Herbert Matare and Heinrich Welker
