Further rebuilding and restoration occurred in the 19th century under Sir George Gilbert Scott.

Problem: Following the Fourth Crusade and the fall of Constantinople to the "Latins" in 1204 mainland Greece was split between the Greek Despotate of Epirus (a Byzantine successor state) and Frankish rule (known as the Frankokratia), while some islands came under Venetian rule. The re-establishment of the Byzantine imperial capital in Constantinople in 1261 was accompanied by the empire's recovery of much of the Greek peninsula, although the Frankish Principality of Achaea in the Peloponnese and the rival Greek Despotate of Epirus in the north both remained important regional powers into the 14th century, while the islands remained largely under Genoese and Venetian control.
In 1261 Constantinople was the capital for which empire?

Answer: Byzantine

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the early 2000s, print media in Somalia reached a peak in activity. Around 50 newspapers were published in Mogadishu alone during this period, including Qaran, Mogadishu Times, Sana'a, Shabelle Press, Ayaamaha, Mandeeq, Sky Sport, Goal, The Nation, Dalka, Panorama, Aayaha Nolosha, Codka Xuriyada and Xidigta Maanta. In 2003, as new free electronic media outlets started to proliferate, advertisers increasingly began switching over from print ads to radio and online commercials in order to reach more customers. A number of the broadsheets in circulation subsequently closed down operations, as they were no longer able to cover printing costs in the face of the electronic revolution. In 2012, the political Xog Doon and Xog Ogaal and Horyaal Sports were reportedly the last remaining newspapers printed in the capital. According to Issa Farah, a former editor with the Dalka broadsheet, newspaper publishing in Somalia is likely to experience a resurgence if the National Somali Printing Press is re-opened and the sector is given adequate public support.
How many newspapers were published in Somalia?
A: unanswerable

Context and question: Westminster diocese was dissolved in 1550, but the abbey was recognised (in 1552, retroactively to 1550) as a second cathedral of the Diocese of London until 1556. The already-old expression "robbing Peter to pay Paul" may have been given a new lease of life when money meant for the abbey, which is dedicated to Saint Peter, was diverted to the treasury of St Paul's Cathedral.
When was Westminster Diocese dissolved?
Answer: 1550

Question: The cup triumph was also Everton's passport to the Cup Winners' Cuptheir first European campaign in the post-Heysel era. Progress under Joe Royle continued in 199596 as they climbed to sixth place in the Premiership. A fifteenth-place finish the following season saw Royle resign towards the end of the campaign, to be temporarily replaced by club captain, Dave Watson. Howard Kendall was appointed Everton manager for the third time in 1997, but the appointment proved unsuccessful as Everton finished seventeenth in the Premiership; only avoiding relegation due to their superior goal difference over Bolton Wanderers. Former Rangers manager Walter Smith then took over from Kendall in the summer of 1998 but only managed three successive finishes in the bottom half of the table.
Is there an answer to this question: During what season was Dave Watson made club captain?

Answer: unanswerable

QUES: While highly effective, the requirement for injection limited the use of norepinephrine[clarification needed] and orally active derivatives were sought. A structurally similar compound, ephedrine, was identified by Japanese chemists in the Ma Huang plant and marketed by Eli Lilly as an oral treatment for asthma. Following the work of Henry Dale and George Barger at Burroughs-Wellcome, academic chemist Gordon Alles synthesized amphetamine and tested it in asthma patients in 1929. The drug proved to have only modest anti-asthma effects, but produced sensations of exhilaration and palpitations. Amphetamine was developed by Smith, Kline and French as a nasal decongestant under the trade name Benzedrine Inhaler. Amphetamine was eventually developed for the treatment of narcolepsy, post-encepheletic parkinsonism, and mood elevation in depression and other psychiatric indications. It received approval as a New and Nonofficial Remedy from the American Medical Association for these uses in 1937 and remained in common use for depression until the development of tricyclic antidepressants in the 1960s.

When were tricyclic antidepressants developed?
What is the answer?
ANS:
1960s
