Problem: Gothic architecture:

In 1663 at the Archbishop of Canterbury's residence, Lambeth Palace, a Gothic hammerbeam roof was built to replace that destroyed when the building was sacked during the English Civil War. Also in the late 17th century, some discrete Gothic details appeared on new construction at Oxford University and Cambridge University, notably on Tom Tower at Christ Church, Oxford, by Christopher Wren. It is not easy to decide whether these instances were Gothic survival or early appearances of Gothic revival.

What is the name of the Archbishop of Canterbury's residence?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
First, the Manchus had entered "China proper" because Dorgon responded decisively to Wu Sangui's appeal. Then, after capturing Beijing, instead of sacking the city as the rebels had done, Dorgon insisted, over the protests of other Manchu princes, on making it the dynastic capital and reappointing most Ming officials. Choosing Beijing as the capital had not been a straightforward decision, since no major Chinese dynasty had directly taken over its immediate predecessor's capital. Keeping the Ming capital and bureaucracy intact helped quickly stabilize the regime and sped up the conquest of the rest of the country. However, not all of Dorgon's policies were equally popular nor easily implemented.
Whose capital was Beijing before the Manchu's?
A: Ming

Context and question: Many ancient works, such as the Bible and the Greek tragedies,[citation needed] survive in hundreds of copies, and the relationship of each copy to the original may be unclear. Textual scholars have debated for centuries which sources are most closely derived from the original, hence which readings in those sources are correct.[citation needed] Although biblical books that are letters, like Greek plays, presumably had one original, the question of whether some biblical books, like the Gospels, ever had just one original has been discussed. Interest in applying textual criticism to the Qur'an has also developed after the discovery of the Sana'a manuscripts in 1972, which possibly date back to the 78th centuries.
Interest in an analysis of what text has arose in the early 8th century?
Answer: unanswerable

Question: At the end of the 1980s, Estonians perceived their demographic change as a national catastrophe. This was a result of the migration policies essential to the Soviet Nationalisation Programme aiming to russify Estonia administrative and military immigration of non-Estonians from the USSR coupled with the deportation of Estonians to the USSR. In the decade following the reconstitution of independence, large-scale emigration by ethnic Russians and the removal of the Russian military bases in 1994 caused the proportion of ethnic Estonians in Estonia to increase from 61% to 69% in 2006.
Is there an answer to this question: How did Estonians view the demographic change of less ethnic Estonians?

Answer: a national catastrophe
