Which of the following statement is/are NOT true in respect of human settlements?

Urban settlements specialized mainly in tertiary activities.

The process of settlement inherently involves grouping of people and apportioning of territory as their resource base. Settlements vary in size and type. They range from a hamlet to metropolitan cities. With size, the economic character and social structure of settlements changes and so do its ecology and technology. Settlements could be small and sparsely spaced; they may also be large and closely spaced. The sparsely located small settlements are called villages, specialising in agriculture or other primary activities. On the other hand, there are fewer but larger settlements which are termed urban settlements specializing in secondary and tertiary activities.
