Q: Question: What role did the actor who had played the ninth doctor take after his time on the show? Passage:The regeneration of the Ninth Doctor into the Tenth at the end of "The Parting of the Ways" (2005) used computer effects to morph Christopher Eccleston into David Tennant. In the episode of Doctor Who Confidential accompanying the episode "Utopia" (2007), where the same effect is used for the Master's regeneration, it is stated that the production team decided that this would be a common effect for all future Time Lord regenerations, rather than each regeneration being designed uniquely at the whim of the individual director. This style of transition is seen again in "The Stolen Earth"/"Journey's End" (2008) both when the Doctor undergoes an aborted regeneration, and when his hand spawns a clone in the second part; in The End of Time (2010) during which Matt Smith took over the role as the Eleventh Doctor; in "The Impossible Astronaut" when the Doctor is shot twice and seemingly killed; in "Day of the Moon" when a young girl regenerates; and in "Let's Kill Hitler" when Mels (Nina Toussaint-White) is shot and regenerates into River Song (Alex Kingston). "The Night of the Doctor" and "The Day of the Doctor" subsequently use the effect to show the Eighth Doctor and War Doctor's regenerations respectively. The Eighth Doctor's regeneration into the War Doctor uses steady beams of light as opposed to the flame effect used for other revived series regenerations. In the Series 10 episode "The Lie of the Land", the Twelfth Doctor fakes a regeneration as part of a plan to test if Bill still has free will. The effect used is consistent with the one used in the modern series, with the Doctor's hands glowing and emitting regeneration energy before he enters full regeneration. However, as the regeneration was not real, it did not use up a regeneration and the Doctor did not change bodies.

Q: Question: Which of the decidousous plants that border Igelbäcken is the most abundant in the world?  Passage:The upper part of the watershed is constituted of Norra Järvafältet, an open-air area characterized by moraine ridges covered with forests separated by water meadows and tilled fields. While some 20 hectares of the surrounding area is used for pasture, the stream is bordered by deciduous plants such as Alder and Birch and Bulrush can be found in non-shadowed patches. Some 2,5 kilometres from its origin, the stream passes down in a culvert under a traffic route (Akallavägen) and the Barkarby Airport before merging with the stream Djupanbäcken. This part of the catchment area contains a motocross track, a golf driving range, a closed dump, and receives stormwater from the E18 traffic route. Thereafter, the stream flows some 4 km in the valley separating the suburbs Akalla-Hjulsta and Tensta-Rinkeby and where are several rural structures including an ecological farm (Hästa Gård), eight allotment-gardens, and some minor overgrown wetlands. East of the valley the river is crossed by a second traffic route (Kymlingelänken) before flowing 2,5 km through an open grassland to reach a railway and the E4 traffic route, water from the latter treated in a local cleaning plant. The last 1.4 km passes more allotment-gardens and the gardens of the Ulriksdal Palace before jumping into Edsviken through a low dam.

Q: Question: In what year was the house the Vogtei went to after the Lenzburg family established? Passage:The first mention of modern Hägglingen is in 1036 when Count Ulrich von Lenzburg granted the church and farm of Hekelingen to Beromünster. In the acknowledgments of Emperor Henry III in 1045, the village of Hackelingen was mentioned. Frederick I Barbarossa acknowledged the grants to the village in 1173. The Vogtei (bailiwick) went from the Lenzburg family to the Kyburgs and then in 1273 to the Lords of Hallwyl. The high court rights were exercised by the Habsburgs until the Swiss conquered the Aargau in 1415. It was not until 1425 that Hägglingen, which was claimed by Lucerne, came under the authority of the entire Confederacy. It was first assigned to the district court of Wohlenschwil before it became an independent municipality from 1435-1712.
