Context and question: In 2002, Chinese geologist Chen Xuezhong published a Seismic Risk Analysis study in which he came to the conclusion that beginning with 2003, attention should be paid to the possibility of an earthquake with a magnitude of over 7.0 occurring in Sichuan region. He based his study on statistical correlation. That Sichuan is a seismically active area has been discussed for years prior to the quake, though few studies point to a specific date and time.
In what year did Chen Xuezhong publish an earthquake study?

Context and question: The late Georgian period saw the birth of the semi-detached house, planned systematically, as a suburban compromise between the terraced houses of the city and the detached "villas" further out, where land was cheaper. There had been occasional examples in town centres going back to medieval times. Most early suburban examples are large, and in what are now the outer fringes of Central London, but were then in areas being built up for the first time. Blackheath, Chalk Farm and St John's Wood are among the areas contesting being the original home of the semi. Sir John Summerson gave primacy to the Eyre Estate of St John's Wood. A plan for this exists dated 1794, where "the whole development consists of pairs of semi-detached houses, So far as I know, this is the first recorded scheme of the kind". In fact the French Wars put an end to this scheme, but when the development was finally built it retained the semi-detached form, "a revolution of striking significance and far-reaching effect".
What put an end to the scheme of semi-detached houses?
Answer: the French Wars
