In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Example Input: 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.

Example Input: Question: Who won the season of X factor that Cowell was a judge with newcomer Rita Ora? Passage:In October 2013, it was reported that Cowell may return to the UK version of The X Factor for series 11 in the place of Gary Barlow, and on 7 February 2014, his return was officially confirmed. This resulted in the cancellation of the US version after three seasons by Fox. He joined judges Louis Walsh, Cheryl Fernandez-Versini, and new judge, former Spice Girls member Mel B, who replaced Nicole Scherzinger. For his eighth series, he was given the Over 25s category. On 13 December, Ben Haenow and Fleur East reached the final two, which meant that Cowell was the winning mentor for the first time since series 3 in 2006, when he had both Leona Lewis and Ray Quinn in the final. Haenow became the eleventh winner on 14 December. In March 2015, it was announced that Cowell would return to the X Factor for its twelfth series along with veteran judge Cheryl Fernandez-Versini, and newcomers Rita Ora and BBC Radio 1 DJ Nick Grimshaw.
