Which one of the following statements would undermine the author’s stand regarding the greenness of cities?
The high density of cities leads to an increase in carbon dioxide and global warming.
To determine which statement undermines the author's stand on the greenness of cities, we must consider the author's main arguments regarding urban density and environmental impact.
The author suggests that:
Given these points, the statement that most contradicts the author's position is:
The high density of cities leads to an increase in carbon dioxide and global warming.
This challenges the core argument that urban density leads to reduced pollution and enhanced environmental sustainability.
their transportation is energy efficient.
regard cities as places of disease and crime.
We are tasked with inferring why Calthorpe’s statement “still jars” with most people, based on the comprehension provided. The comprehension discusses the environmental efficiency of urban density and squatter cities. Despite their chaotic appearance, these cities are described as having ecological benefits due to their compactness. The key aspects highlighted include the reduction in land, energy, and resource consumption per individual when compared to less dense settlements.
The comprehension mentions that people often have negative perceptions of cities, associating them with issues like crime, pollution, and disease. However, the focus here is to determine why Calthorpe's assertion about cities being "environmentally benign" is jarring.
Analyzing the comprehension, the main reason the statement jars is due to the commonly held belief that cities are not considered eco-friendly places. While the text explains the environmental benefits of city density, it contrasts with the perception that cities contribute to environmental hazards, which Calthorpe’s statement challenges.
Considering this analysis, the best option aligns with the idea that most people:
describe the infrastructure efficiencies of living in a city.
The author refers to Manaus to illustrate how urban areas contribute positively to the environment. The passage highlights the transformative effects that cities can have, particularly in reducing environmental impact. It mentions several points supporting this including:
These points align with the choice that the author mentions Manaus to explain how urban areas help the environment, forming a central theme in the discussion about the positive roles cities can play, especially regarding ecological concerns. Therefore, the correct answer is: explain how urban areas help the environment.
From the passage it can be inferred that cities are good places to live in for all of the following reasons EXCEPT that they:
help prevent destruction of the environment.
have suburban areas as well as office areas.
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.
