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.

Question: How old was the military engineer who scouted around Leith during the siege? Passage:The English King Henry VIII, angered by the Scots reneging on the initial agreement, made war on Scotland in 1544–1549, a period which the writer Sir Walter Scott later christened the "Rough Wooing". In May 1544 an English army landed at Granton and captured Leith to land heavy artillery for an assault on Edinburgh Castle, but withdrew after burning the town and the Palace of Holyrood over three days. Three years later, following another English invasion and victory at Pinkie Cleugh in 1547, the English attempted to establish a "pale" within Scotland. Leith was of prime strategic importance because of its vital role as Edinburgh's port, handling its foreign trade and essential supplies. The English arrived in Leith on 11 September 1547 and camped on Leith Links. The military engineer Richard Lee scouted around the town on 12 September looking to see if it could be made defensible. On 14 September the English began digging a trench on the south-east side of Leith near the Firth of Forth. William Patten wrote that the work was done as much for exercise as for defence, since the army only stayed for five days.

Question: In what year was film criticism renamed the Pure Film Movement? Passage:Among intellectuals, critiques of Japanese cinema grew in the 1910s and eventually developed into a movement that transformed Japanese film. Film criticism began with early film magazines such as Katsudō shashinkai (begun in 1909) and a full-length book written by Yasunosuke Gonda in 1914, but many early film critics often focused on chastising the work of studios like Nikkatsu and Tenkatsu for being too theatrical (using, for instance, elements from kabuki and shinpa such as onnagata) and for not utilizing what were considered more cinematic techniques to tell stories, instead relying on benshi. In what was later named the Pure Film Movement, writers in magazines such as Kinema Record called for a broader use of such cinematic techniques. Some of these critics, such as Norimasa Kaeriyama, went on to put their ideas into practice by directing such films as The Glow of Life (1918), which was one of the first films to use actresses (in this case, Harumi Hanayagi). There were parallel efforts elsewhere in the film industry. In his 1917 film The Captain's Daughter, Masao Inoue started using techniques new to the silent film era, such as the close-up and cut back. The Pure Film Movement was central in the development of the gendaigeki and scriptwriting.
