The correct answer is (D):
(1), (2) and (3) are mentioned in the second paragraph, refer to “diverse populations” - (2), “new ideas” - (1) and “infrastructure for finance, organization” - (3).
The correct answer is (B):
While (4) is beside the point, (1) does not address the question at hand. (3) goes contrary to received wisdom in the passage. (2) is explicitly mentioned in the third paragraph, refer to “what staunches creativity …. It's the very institutions”
The correct answer is (A):
Neither (2) nor (3) are mentioned as such in the passage. (4) is a recommendation, not the central idea of the passage. The passage is on creativity, and the central idea can be found in the first paragraph itself - “What fosters creativity? … the presence of other creative people”, a theme that resonates throughout the passage.
The correct answer is (C):
The alarming view in (2) is not echoed in the passage. (4) also runs contrary to the passage, Jane Jacobs argues in the fifth paragraph that all cities are filled with creative people. (1) is a lay opinion. Jane Jacobs argues that “some cities had more than their shares of leaders, people and institutions that blocked out that creativity”, hence we can safely infer that the more creative cities have leaders and institutions that do not block creativity.
The correct answer is (B):(1) again runs contrary to the passage, which places creativity as inversely proportional to age. (4) is not mentioned in the passage. (3) paints with too brand a brush. (2) is resonated in the third paragraph, “staunches creativity … many of our schools”.
The correct answer is (A):
(2) is not supported by the passage, refer to “the other 66 percent who toil” in the sixth paragraph. The recommendation in (3) is not the author's. (4) assumes that low-wage workers are creative, which is suspect. The author mentions “work which engages our creative faculties … those of us who work with our minds”, the assumption then being that those who work with their hands are not creative.
Trade is essentially the buying and selling of items produced elsewhere. All the services in retail and wholesale trading or commerce are specifically intended for profit. The towns and cities where all these works take place are known as trading centres. The rise of trading from barter at the local level to money-exchange on an international scale has produced many centres and institutions, such as trading centres or collection and distribution points.
Trading centres may be divided into rural and urban marketing centres. Rural marketing centres cater to nearby settlements. These are quasi-urban centres. They serve as trading centres of the most rudimentary type. Here, personal and professional services are not well-developed. These form local collecting and distributing centres. Most of these have mandis (wholesale markets) and also retailing areas. They are not urban centres per se but are significant centres for making available goods and services which are most frequently demanded by rural folk.
Periodic markets in rural areas are found where there are no regular markets and local periodic markets are organised at different temporal intervals. These may be weekly, bi-weekly markets where people from the surrounding areas meet their temporally accumulated demand. These markets are held on specified dates and move from one place to another. The shopkeepers, thus, remain busy all day while a large area is served by them.
Urban marketing centres have more widely specialised urban services. They provide ordinary goods and services as well as many of the specialised goods and services required by people. Ur- ban centres, therefore, offer manufactured goods as well as many specialised developed markets, e.g. markets for labour, housing, semi-or finished products. Services of educational institutions and professionals such as teachers, lawyers, consultants, physicians, dentists and veterinary doctors are available.
