Problem: Charleston, South Carolina:

The Jenkins Orphanage was established in 1891 by the Rev. Daniel J. Jenkins in Charleston. The orphanage accepted donations of musical instruments and Rev. Jenkins hired local Charleston musicians and Avery Institute Graduates to tutor the boys in music. As a result, Charleston musicians became proficient on a variety of instruments and were able to read music expertly. These traits set Jenkins musicians apart and helped land some of them positions in big bands with Duke Ellington and Count Basie. William "Cat" Anderson, Jabbo Smith, and Freddie Green are but a few of the alumni from the Jenkins Orphanage band who became professional musicians in some of the best bands of the day. Orphanages around the country began to develop brass bands in the wake of the Jenkins Orphanage Band's success. At the Colored Waif's Home Brass Band in New Orleans, for example, a young trumpeter named Louis Armstrong first began to draw attention.

Whose graduates tutored many girls from the Jenkins Orphanage?

A: unanswerable


Problem: Theologus Autodidactus, written by the Arabian polymath Ibn al-Nafis (1213–1288), is the first example of a science fiction novel. It deals with various science fiction elements such as spontaneous generation, futurology, the end of the world and doomsday, resurrection, and the afterlife. Rather than giving supernatural or mythological explanations for these events, Ibn al-Nafis attempted to explain these plot elements using the scientific knowledge of biology, astronomy, cosmology and geology known in his time. Ibn al-Nafis' fiction explained Islamic religious teachings via science and Islamic philosophy.
What events did Ibn al-Nafis give supernatural or mythological explanations?

Context and question: While the housing and credit bubbles were building, a series of factors caused the financial system to both expand and become increasingly fragile, a process called financialization. U.S. Government policy from the 1970s onward has emphasized deregulation to encourage business, which resulted in less oversight of activities and less disclosure of information about new activities undertaken by banks and other evolving financial institutions. Thus, policymakers did not immediately recognize the increasingly important role played by financial institutions such as investment banks and hedge funds, also known as the shadow banking system. Some experts believe these institutions had become as important as commercial (depository) banks in providing credit to the U.S. economy, but they were not subject to the same regulations.
What institutions comprise the shadow banking system?
Answer: investment banks and hedge funds


Question: The Scottish traveler James Bruce reported in 1770 that Medri Bahri was a distinct political entity from Abyssinia, noting that the two territories were frequently in conflict. The Bahre-Nagassi ("Kings of the Sea") alternately fought with or against the Abyssinians and the neighbouring Muslim Adal Sultanate depending on the geopolitical circumstances. Medri Bahri was thus part of the Christian resistance against Imam Ahmad ibn Ibrahim al-Ghazi of Adal's forces, but later joined the Adalite states and the Ottoman Empire front against Abyssinia in 1572. That 16th century also marked the arrival of the Ottomans, who began making inroads in the Red Sea area.
Is there an answer to this question: In 1770, who reported that Medri Bahri was a distinct political entity from Abyssinia?

Answer: James Bruce


Problem: Karl Popper:

In 1928, he earned a doctorate in psychology, under the supervision of Karl Bühler. His dissertation was entitled "Die Methodenfrage der Denkpsychologie" (The question of method in cognitive psychology). In 1929, he obtained the authorisation to teach mathematics and physics in secondary school, which he started doing. He married his colleague Josefine Anna Henninger (1906–1985) in 1930. Fearing the rise of Nazism and the threat of the Anschluss, he started to use the evenings and the nights to write his first book Die beiden Grundprobleme der Erkenntnistheorie (The Two Fundamental Problems of the Theory of Knowledge). He needed to publish one to get some academic position in a country that was safe for people of Jewish descent. However, he ended up not publishing the two-volume work, but a condensed version of it with some new material, Logik der Forschung (The Logic of Scientific Discovery), in 1934. Here, he criticised psychologism, naturalism, inductionism, and logical positivism, and put forth his theory of potential falsifiability as the criterion demarcating science from non-science. In 1935 and 1936, he took unpaid leave to go to the United Kingdom for a study visit.

What subjects was Popper authorized to teach in secondary school in 1929?
---
A:
mathematics and physics
