PROBLEM: Passage: Allen was born into a prominent Philadelphia family. His father, William Allen, was a successful merchant and lawyer, and would later be the Chief Justice of the Supreme Court of Pennsylvania. Andrew graduated from the City College of Philadelphia (later the University of Pennsylvania) in 1759, read law under Benjamin Chew, and then went to London to complete a legal education at the Inner Temple. He returned to Philadelphia in 1765, was admitted to the bar, and began to practice law. That same year Allen was elected to the Pennsylvania Assembly. In 1766, he was appointed the colony's Attorney General. He married Sarah ("Sally") Coxe, sister of Tench Coxe, in April 1768. In 1770 his brother-in-law, Governor John Penn, gave him a seat on the Governor's Council.

PROBLEM: Passage: Slavic tribes settled in the Balkan region including North Macedonia by the late 6th century AD. During the 580s, Byzantine literature attests to the Slavs raiding Byzantine territories in the region of Macedonia, later aided by Bulgars. Historical records document that in c. 680 a group of Bulgars, Slavs and Byzantines led by a Bulgar called Kuber settled in the region of the Keramisian plain, centred on the city of Bitola, forming a second route for the Bulgar definitive settlement on the Balkan Peninsula at the end of the 7th century. Presian's reign apparently coincides with the extension of Bulgarian control over the Slavic tribes in and around Macedonia. The Slavic tribes that settled in the region of Macedonia converted to Christianity around the 9th century during the reign of Tsar Boris I of Bulgaria. The Ohrid Literary School became one of the two major cultural centres of the First Bulgarian Empire, along with the Preslav Literary School. Established in Ohrid in 886 by Saint Clement of Ohrid on the order of Boris I, the Ohrid Literary School was involved in the spreading of the Cyrillic.
 Link Information: The 6th century Byzantine historian Jordanes, wrote in his 551 AD work Getica: "although they derive from one nation, now they are known under three names, the Veneti, Antes and Sclaveni" Question: How many different slavic tribes were there in the 6th century?

SOLUTION: Answer: 3

PROBLEM: Passage: Ross married Bertha (Bee) Halley Horecker, a singer-musician and daughter of Ross's Chicago neighbors, in 1931, received a National Research Council Fellowship for 1932, and worked as a National Research Council postdoctoral fellow at California Institute of Technology with Eric Temple Bell until 1933. Ross moved back to Chicago and led the mathematics department at an experimental school started by Ph.D.s during the Great Depression, People's Junior College, where he also taught physics. Ross became an assistant professor at St. Louis University in 1935 and stayed for about 11 years. In an interview, he said he advocated for a student who became the first black woman in the South to receive a master's degree in mathematics. This exception led the university to admit black students despite the idea's widespread unpopularity. During World War II, Ross served as a research mathematician for the U.S. Navy. He befriended Hungarian mathematician Gábor Szegő while in St. Louis, who recommended Ross for a 1941 Brown University summer school that prepared young scientists to assist in the war, a program Ross attended. He occasionally worked on proximity fuzes for Stromberg-Carlson's laboratory from 1941 to 1945 before accepting a position as head of University of Notre Dame's mathematics department in 1946. He set out to change the school's research climate by inviting distinguished mathematicians including Paul Erdős, whom Ross made a full professor.
