Problem: The island is subject to separate immigration controls from the remainder of Australia. Until recently immigration to Norfolk Island even by other Australian citizens was heavily restricted. In 2012, immigration controls were relaxed with the introduction of an Unrestricted Entry Permit for all Australian and New Zealand citizens upon arrival and the option to apply for residency; the only criteria are to pass a police check and be able to pay into the local health scheme. From 1 July 2016, the Australian migration system will replace the immigration arrangements currently maintained by the Norfolk Island Government.

Problem: Sanskrit (/snskrt/; Sanskrit: samskrtam [smskrtm] or samskrta, originally samskrta vak, "refined speech") is the primary sacred language of Hinduism, a philosophical language in Buddhism, Hinduism, Sikhism and Jainism, and a literary language that was in use as a lingua franca in Greater India. It is a standardised dialect of Old Indo-Aryan, originating as Vedic Sanskrit and tracing its linguistic ancestry back to Proto-Indo-Iranian and Proto-Indo-European. Today it is listed as one of the 22 scheduled languages of India and is an official language of the state of Uttarakhand. As one of the oldest Indo-European languages for which substantial written documentation exists, Sanskrit holds a prominent position in Indo-European studies.
Where is Sanskrit usually found?

Problem: Through the force of sheer numbers, the English-speaking American settlers entering the Southwest established their language, culture, and law as dominant, to the extent it fully displaced Spanish in the public sphere; this is why the United States never developed bilingualism as Canada did. For example, the California constitutional convention of 1849 had eight Californio participants; the resulting state constitution was produced in English and Spanish, and it contained a clause requiring all published laws and regulations to be published in both languages. The constitutional convention of 1872 had no Spanish-speaking participants; the convention's English-speaking participants felt that the state's remaining minority of Spanish-speakers should simply learn English; and the convention ultimately voted 46-39 to revise the earlier clause so that all official proceedings would henceforth be published only in English.
Is Canada bilingual?
The answer is the following: United States never developed bilingualism as Canada did.

Problem: 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?
The answer is the following:
the French Wars
