Problem: Hellenistic period:

The most important source after Polybius is Diodorus Siculus who wrote his Bibliotheca historica between 60 and 30 BCE and reproduced some important earlier sources such as Hieronymus, but his account of the Hellenistic period breaks off after the battle of Ipsus (301). Another important source, Plutarch's (c.50—c.120) Parallel Lives though more preoccupied with issues of personal character and morality, outlines the history of important Hellenistic figures. Appian of Alexandria (late first century CE-before 165 CE) wrote a history of the Roman empire that includes information of some Hellenistic kingdoms.

Where was Apprian from?

A: Alexandria


Problem: In February 1925, the Cardinal Secretary of State Pietro Gasparri summoned him to the Vatican and informed him of Pope Pius XI's decision to appoint him as the Apostolic Visitor to Bulgaria (1925–35). On 3 March, Pius XI also named him for consecration as titular archbishop of Areopolis, Jordan. Roncalli was initially reluctant about a mission to Bulgaria, but he would soon relent. His nomination as apostolic visitor was made official on 19 March. Roncalli was consecrated by Giovanni Tacci Porcelli in the church of San Carlo alla Corso in Rome. After he was consecrated, he introduced his family to Pope Pius XI. He chose as his episcopal motto Obedientia et Pax ("Obedience and Peace"), which became his guiding motto. While he was in Bulgaria, an earthquake struck in a town not too far from where he was. Unaffected, he wrote to his sisters Ancilla and Maria and told them both that he was fine.
When was Pius XI asked to come to the Vatican by the Cardinal Secretary of State?

Context and question: Numerous immigrants have come as merchants and become a major part of the business community, including Lebanese, Indians, and other West African nationals. There is a high percentage of interracial marriage between ethnic Liberians and the Lebanese, resulting in a significant mixed-race population especially in and around Monrovia. A small minority of Liberians of European descent reside in the country.[better source needed] The Liberian constitution restricts citizenship to people of Black African descent.
Where do Liberians of Black African descent live?
Answer: unanswerable


Question: When comparing different documents, or "witnesses", of a single, original text, the observed differences are called variant readings, or simply variants or readings. It is not always apparent which single variant represents the author's original work. The process of textual criticism seeks to explain how each variant may have entered the text, either by accident (duplication or omission) or intention (harmonization or censorship), as scribes or supervisors transmitted the original author's text by copying it. The textual critic's task, therefore, is to sort through the variants, eliminating those most likely to be un-original, hence establishing a "critical text", or critical edition, that is intended to best approximate the original. At the same time, the critical text should document variant readings, so the relation of extant witnesses to the reconstructed original is apparent to a reader of the critical edition. In establishing the critical text, the textual critic considers both "external" evidence (the age, provenance, and affiliation of each witness) and "internal" or "physical" considerations (what the author and scribes, or printers, were likely to have done).
Is there an answer to this question: When do variations enter a witness text?

Answer: unanswerable


Problem: Frédéric Chopin:

Fryderyk may have had some piano instruction from his mother, but his first professional music tutor, from 1816 to 1821, was the Czech pianist Wojciech Żywny. His elder sister Ludwika also took lessons from Żywny, and occasionally played duets with her brother. It quickly became apparent that he was a child prodigy. By the age of seven Fryderyk had begun giving public concerts, and in 1817 he composed two polonaises, in G minor and B-flat major. His next work, a polonaise in A-flat major of 1821, dedicated to Żywny, is his earliest surviving musical manuscript.

What is the name of Chopin's first music teacher that was not an amateur musician?
---
A:
Wojciech Żywny
