Directions: Read the following paragraph and answer the question that follows.
A pattern of black minority ethnic settlement, characterised by residential concentration, segregation and deprivation is now well established in Britain. Although this distinctive geography is largely a product of post-war migration, black settlers have a long history in Britain; small clusters of Africans and Indians emerged in port areas such as London, Liverpool and Cardiff as early as the 1800s. These settlements were, however, extremely localised, so the day-to-day experience of most people living in Britain at that time was a white one. The Victorians nevertheless held some clearly developed images of 'race', colour and ethnic difference, which were rooted in colonial relations with South Asian and West Indian countries. The largely negative stereotypes associated with 'uncivilised people' in far-off lands were to prove powerful constituents of 19th century racist ideologies, which have survived, albeit in a modified form, into the late 20th century.
