Indicate your choice as `a` for Yes or `b` for No.

[EX Q]: Question: In what year did Joseph's son die? Passage:In the biblical account, Joseph's other son is Manasseh, and Joseph himself is one of the two children of Rachel and Jacob, the other being Benjamin. Biblical scholars regard it as obvious, from their geographic overlap and their treatment in older passages, that originally Ephraim and Manasseh were considered one tribe – that of Joseph. The Book of Revelation, however, accords only Ephraim the tribal name of Joseph. According to several biblical scholars, Benjamin was originally part of the suggested Ephraim-Manasseh single "Joseph" tribe, but the biblical account of Joseph as his father became lost. A number of biblical scholars suspect that the distinction of the Joseph tribes (including Benjamin) is that they were the only Israelites which went to Egypt and returned, while the main Israelite tribes simply emerged as a subculture from the Canaanites and had remained in Canaan throughout. According to this view, the story of Jacob's visit to Laban to obtain a wife originated as a metaphor for this migration, with the property and family which were gained from Laban representing the gains of the Joseph tribes by the time they returned from Egypt; according to textual scholars, the Jahwist version of the Laban narrative only mentions the Joseph tribes, and Rachel, and does not mention the other tribal matriarchs at all.

[EX Q]: Question: How many countries border the body of water on the coast of which Hommaire coordinated the construction of a lighthouse? Passage:After attending school in Altkirch and Dijon, Hommaire graduated as an engineer at the École des Mines in Saint-Étienne in 1833. There he met Adèle Hériot whom he married in 1834. In October 1835, he went Turkey where he coordinated the construction of a suspension bridge in Constantinople and a lighthouse on the Black Sea coast. In 1838, he arrived in southern Russia where he performed ethnographical research and geographical surveys. After he discovered coal resources along the Dnieper River, Czar Nicholas I awarded him the St Vladimir Cross. In 1842, while working on mining and road-building projects in Moldavia, he fell ill and returned to France. The following year he became a member of the Société de Géographie and the Société géologique and published a number of scientific papers. In 1844 the Société de Géographie awarded him their Gold Medal .

[EX Q]: Question: Who did West Germany defeat to win the 1954 FIFA World Cup in Switzerland? Passage:Following the end of World War II, Germany was partitioned into rival West and East zones, each with their own football systems. The general turmoil of the period and the country's lack of international footballing pedigree up to that point meant it was a surprise to many when West Germany won the 1954 FIFA World Cup in neighbouring Switzerland. It was in the mid-1960s when German football became very strong, with the backbone of the national squad formed by an exceptional group of young players at FC Bayern Munich, soon augmented further by another very strong team at Borussia Monchengladbach and others from the leading clubs. After reaching the 1966 FIFA World Cup Final, they built on victory in UEFA Euro 1972 by winning the 1954 FIFA World Cup on home soil. A further Euro win in 1980 (after an unexpected loss in the 1976 final), plus further World Cup final appearances in 1982 and 1986 confirmed their status as one of the world's most consistently powerful teams. With the end of the Cold War and reunification of the country approaching at the end of the 1980s, the final achievement of West Germany was winning the 1990 FIFA World Cup.
