Problem: Westminster Abbey:

The proximity of the Palace of Westminster did not extend to providing monks or abbots with high royal connections; in social origin the Benedictines of Westminster were as modest as most of the order. The abbot remained Lord of the Manor of Westminster as a town of two to three thousand persons grew around it: as a consumer and employer on a grand scale the monastery helped fuel the town economy, and relations with the town remained unusually cordial, but no enfranchising charter was issued during the Middle Ages. The abbey built shops and dwellings on the west side, encroaching upon the sanctuary.[citation needed]

What did the abbey build on the east side?

A: unanswerable

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Norfolk Island was originally a colony acquired by settlement but was never within the British Settlements Act. It was accepted as a territory of Australia, separate from any state, by the Norfolk Island Act 1913 (Cth), passed under the territories power (Constitution section 122) and made effective in 1914. In 1976 the High Court of Australia held unanimously that Norfolk Island is a part of the Commonwealth. Again, in 2007 the High Court of Australia affirmed the validity of legislation that made Australian citizenship a necessary qualification for voting for, and standing for election to, the Legislative Assembly of Norfolk Island.
What country did Norfolk Island became a city of?
A: unanswerable

Context and question: A route through Beringia is seen as more likely than the Solutrean hypothesis. Kashani et al. 2012 state that "The similarities in ages and geographical distributions for C4c and the previously analyzed X2a lineage provide support to the scenario of a dual origin for Paleo-Indians. Taking into account that C4c is deeply rooted in the Asian portion of the mtDNA phylogeny and is indubitably of Asian origin, the finding that C4c and X2a are characterized by parallel genetic histories definitively dismisses the controversial hypothesis of an Atlantic glacial entry route into North America."
When did Kashani and others make their statement regarding the similarities for C4c distributions?
Answer: 2012

Problem: Imperial College London:

William Henry Perkin studied and worked at the college under von Hofmann, but resigned his position after discovering the first synthetic dye, mauveine, in 1856. Perkin's discovery was prompted by his work with von Hofmann on the substance aniline, derived from coal tar, and it was this breakthrough which sparked the synthetic dye industry, a boom which some historians have labelled the second chemical revolution. His contribution led to the creation of the Perkin Medal, an award given annually by the Society of Chemical Industry to a scientist residing in the United States for an "innovation in applied chemistry resulting in outstanding commercial development". It is considered the highest honour given in the industrial chemical industry.

Who founded the Society of Chemical Industry?
