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 many episodes did Case's character appear in on General Hospital? Passage:In November 1989, Case scored her first television role playing Dawn Winthrop on the ABC Network soap opera General Hospital. Case wanted to "perfect" her audition prior to screen testing as Dawn, who served as the long-lost daughter of the long-running character Monica Quartermaine (Leslie Charleson). Speaking of the audition, Case stated: "I practiced night and day [...] It was a heavy scene in which Dawn learned that her boyfriend Ned (Kurt Robin McKinney) had once slept with her mother! I knew I had to do the best job [possible]". She departed General Hospital the next year, after a guest appearance on another ABC series, the comedy drama Doogie Howser, M.D.. In 1991, Case appeared in various other television series, including Diplomatic Immunity, Beverly Hills, 90210, Parker Lewis Can't Lose and Cheers. From November 1992 to 1993 Case stepped into her second soap opera role, as Debbie Simon on the CBS Network drama As the World Turns. Case has stated that she loved the role, and wanted to stay on to explore more into the character of Debbie who was a "manic depressive", an issue that hadn't been covered on daytime television. During this, she also appeared on the CBS crime drama Silk Stalkings as Bonnie Abagail. In 1994, a year after departing from As the World Turns, she became a regular on the primetime soap opera Valley of the Dolls, which was based on the romantic novel of the same name. In 1997, Case had a role in the HBO film Breast Men. Previously, she turned down a larger role in the film due to being uncomfortable topless on-screen. Instead, she accepted a smaller, clothed role.

Question: Of the states near the border where Hurricane Bob degenerated, which is older? Passage:While moving across Florida, Bob turned to the northeast, then to the north. It subsequently left the peninsula, entering the Atlantic Ocean near Vero Beach early on July 24. As it moved over the warm waters of the Gulf Stream, it quickly organized and intensified into a Category 1 hurricane while east of Jacksonville, Florida. Because it was embedded within the western extension of the subtropical ridge, Bob retained higher-than-average atmospheric pressures throughout its lifespan. The hurricane continued north, and made landfall near Beaufort, South Carolina early on July 25 while maintaining winds of . Bob quickly weakened over land, decaying into a tropical storm three hours after landfall. About 12 hours later, it degenerated into a tropical depression near the North Carolina – Virginia border. Bob's remnants turned north-northeast, and were absorbed by a frontal trough over eastern West Virginia on July 26. An associated area of disturbed weather remained separate from the trough, and continued northeast through the Mid-Atlantic and New England.
