Q: Passage: The eastern arm shows considerable diversity. In England it is generally long and may have two distinct sections, both choir and presbytery. It is often square ended or has a projecting Lady Chapel, dedicated to the Virgin Mary. In France the eastern end is often polygonal and surrounded by a walkway called an ambulatory and sometimes a ring of chapels called a "chevet". While German churches are often similar to those of France, in Italy, the eastern projection beyond the transept is usually just a shallow apsidal chapel containing the sanctuary, as at Florence Cathedral.

A: Which arm in England would generally show no distinct sections?

Even though Tristan da Cunha is a UK overseas territory, it is not permitted direct access to European Union markets.

The fire of 13 February 2008 (see History) resulted in major temporary economic disruption.
