The ceremonial county of Somerset consists of a two-tier non-metropolitan county, which is administered by Somerset County Council and five district councils, and two unitary authority areas (whose councils combine the functions of a county and a district). The five districts of Somerset are West Somerset, South Somerset, Taunton Deane, Mendip, and Sedgemoor. The two unitary authorities which were established on 1 April 1996 following the break-up of the short-lived county of Avon are North Somerset, and Bath & North East Somerset.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the main city of Avon County?
Ah, so.. unanswerable

Following the purchase of an offshore lease in 2005, Shell initiated its US$4.5 billion Arctic drilling program in 2006, after the corporation purchased the "Kulluk" oil rig and leased the Noble Discoverer drillship. At inception, the project was led by Pete Slaiby, a Shell executive who had previously worked in the North Sea. However, after the purchase of a second offshore lease in 2008, Shell only commenced drilling work in 2012, due to the refurbishment of rigs, permit delays from the relevant authorities and lawsuits. The plans to drill in the Arctic led to protests from environmental groups, particularly Greenpeace; furthermore, analysts in the energy field, as well as related industries, also expressed skepticism due to perceptions that drilling in the region is "too dangerous because of harsh conditions and remote locations".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What caused the delay in drilling after Shell's 2008 purchase?
Ah, so.. the refurbishment of rigs, permit delays from the relevant authorities and lawsuits

Yazid died while the siege was still in progress, and the Umayyad army returned to Damascus, leaving Ibn al-Zubayr in control of Mecca. Yazid's son Muawiya II (68384) initially succeeded him but seems to have never been recognized as caliph outside of Syria. Two factions developed within Syria: the Confederation of Qays, who supported Ibn al-Zubayr, and the Quda'a, who supported Marwan, a descendant of Umayya via Wa'il ibn Umayyah. The partisans of Marwan triumphed at a battle at Marj Rahit, near Damascus, in 684, and Marwan became caliph shortly thereafter.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was a descendant of Marwan?
Ah, so..
