Example 9
Read the passage below and answer the questions:
[CAT 2019]
The magic of squatter cities is that they are improved steadily and gradually by their residents. To a planner’s eye, these cities look chaotic. I trained as a biologist and to my eye, they look organic. Squatter cities are also unexpectedly green. They have maximum density—1 million people per square mile in some areas of Mumbai—and have minimum energy and material use. People get around by foot, bicycle, rickshaw, or the universal shared taxi.
Not everything is efficient in the slums, though. In the Brazilian favelas where electricity is stolen and therefore free, people leave their lights on all day. But in most slums recycling is literally a way of life. The Dharavi slum in Mumbai has 400 recycling units and 30,000 ragpickers. Six thousand tons of rubbish are sorted every day. In 2007, the Economist reported that in Vietnam and Mozambique, “Waves of gleaners sift the sweepings of Hanoi’s streets, just as Mozambiquan children pick over the rubbish of Maputo’s main tip. Every city in Asia and Latin America has an industry based on gathering up old cardboard boxes.”...
In his 1985 article, Calthorpe made a statement that still jars with most people: “The city is the most environmentally benign form of human settlement. Each city dweller consumes less land, less energy, less water, and produces less pollution than his counterpart in settlements of lower densities.” “Green Manhattan” was the inflammatory title of a 2004 New Yorker article by David Owen. “By the most significant measures,” he wrote, “New York is the greenest community in the United States, and one of the greenest cities in the world... The key to New York’s relative environmental benignity is its extreme compactness... Placing one and a half million people on a twenty-three-square-mile island sharply reduces their opportunities to be wasteful.” He went on to note that this very compactness forces people to live in the world’s most energy-efficient apartment buildings...
Urban density allows half of humanity to live on 2.8 per cent of the land... Consider just the infrastructure efficiencies. According to a 2004 UN report: “The concentration of population and enterprises in urban areas greatly reduces the unit cost of piped water, sewers, drains, roads, electricity, garbage collection, transport, health care, and schools.” ...
The nationally subsidised city of Manaus in northern Brazil “answers the question” of how to stop deforestation: give people decent jobs. Then they can afford houses, and gain security. One hundred thousand people who would otherwise be deforesting the jungle around Manaus are now prospering in town making such things as mobile phones and televisions....
Of course, fast-growing cities are far from an unmitigated good. They concentrate crime, pollution, disease and injustice as much as business, innovation, education and entertainment... But if they are overall a net good for those who move there, it is because cities offer more than just jobs. They are transformative: in the slums, as well as the office towers and leafy suburbs, the progress is from hick to metropolitan to cosmopolitan...
Question 1 of 5
According to the passage, squatter cities are environment-friendly for all of the following reasons EXCEPT:
(1) their streets are kept clean.
(2) they sort out garbage.
(3) their transportation is energy efficient.
(4) they recycle material.
Solution
In this RC, the author explains the environmental benefits of squatter cities (slums) and cities in general. Let us consider the options to find one which the author has not mentioned.
The author has not mentioned that squatter cities' streets are clean. Therefore, option (1) is the correct choice.
Options (2) and (4) are mentioned in the second paragraph (recycling is literally a way of life... Six thousand tons of rubbish are sorted every day).
Option (3) is mentioned in the first paragraph (minimum energy...use. People get around by foot, bicycle, rickshaw, or the universal shared taxi).
Therefore, we can eliminate these options and select option (1).
Answer: (1) their streets are kept clean.
Question 2 of 5
In the context of the passage, the author refers to Manaus in order to:
(1) describe the infrastructure efficiencies of living in a city.
(2) promote cities as employment hubs for people.
(3) explain how urban areas help the environment.
(4) explain where cities source their labour for factories.
Solution
In the passage, the author tells us that in Manaus, the Brazilian government has successfully reduced deforestation by providing jobs in cities (people who would otherwise be deforesting the jungle around Manaus are now prospering in town making such things as mobile phones and televisions).
Therefore, we can infer that cities can also contribute to the prevention of deforestation. Since none of the options mention deforestation, we can select option (3), preventing deforestation is a way to help the environment.
The other options are referring to benefits for the city-dwellers. These can be eliminated, as the author tells us about Manaus as another example to prove that the city is ecological.
Answer: (3) explain how urban areas help the environment.
Question 3 of 5
From the passage it can be inferred that cities are good places to live in for all of the following reasons EXCEPT that they:
(1) have suburban areas as well as office areas.
(2) offer employment opportunities.
(3) help prevent destruction of the environment.
(4) contribute to the cultural transformation of residents.
Solution
Let us consider the options.
Option (1), while mentioned in the passage, is not given as a benefit of cities. Therefore, this should be the correct choice.
Option (2) is given as a benefit in the example of Manaus. Option (3) is also proven by the same example (people who would otherwise be deforesting the jungle around Manaus are now prospering in town making such things as mobile phones and televisions).
Option (4) is mentioned in the last paragraph (They are transformative...the progress is from hick to metropolitan to cosmopolitan). Progress from being a hick (meaning rustic, bumpkin, not very intelligent) to metropolitan (from a major city, therefore more polished and knowledgeable) to cosmopolitan (worldly, culturally at ease in many countries) implies cultural progress.
Therefore, we can eliminate the other options and select option (1) as the correct choice.
Answer: (1) have suburban areas as well as office areas.
Question 4 of 5
We can infer that Calthorpe’s statement “still jars” with most people because most people:
(1) regard cities as places of disease and crime.
(2) consider cities to be very crowded and polluted.
(3) do not regard cities as good places to live in.
(4) do not consider cities to be eco-friendly places.
Solution
The word jars is used in its verb form in this passage. It means having an unpleasant effect, being incongruous or shocking.
Calthorpe statement itself is that the city is the most benign (harmless) environmentally, compared to other human settlements (such as rural areas). We can infer that this statement will jar people if they do not believe in this. Therefore, we should for an option which is opposite in meaning with Calthorpe's statement.
This is present in option (4).
Options (1) and (2) are unrelated to the environment, they are focussing on the perspective of the city dwellers. Therefore, we can eliminate these options.
Option (3) is more generic, and does not explain why cities are not good places. Therefore, we can eliminate this option in favour of option (4), which is specifically about the environment.
Answer: (4) do not consider cities to be eco-friendly places.
Question 5 of 5
Which one of the following statements would undermine the author’s stand regarding the greenness of cities?
(1) The compactness of big cities in the West increases the incidence of violent crime.
(2) Over the last decade the cost of utilities has been increasing for city dwellers.
(3) Sorting through rubbish contributes to the rapid spread of diseases in the slums.
(4) The high density of cities leads to an increase in carbon dioxide and global warming.
Solution
The author tells us that cities are green because of the following reasons – they use less land owing to high population density, city dwellers use less utilities (energy, water, and other services), and they provide jobs (which has the potential to reduce deforestation).
Let us look for an option which contradicts any one or more of these reasons.
Option (1) is not reducing the “greenness” or ecological nature of cities – crime is bad for humans, but cannot damage the environment. Therefore, we can eliminate this option.
Option (2) is also not damaging the environment. Cost of utilities rising might actually reduce usage. This might also be true in rural areas (since the examiners have not sad that this is increasing only in cities). Therefore, we can eliminate this option as well.
Option (3) also harms only humans and not the environment. In fact, this is mentioned in the passage (They concentrate crime, pollution, disease). Therefore, we can eliminate this option as well.
Option (4), on the other hand, weakens the greenness of cities. As the greenness comes from the high population density (less land and utilities per person), this option weakens the author's stand as it showcases the issues with high population density. The issue itself (carbon emissions and global warming) are considerably damaging to the environment. Thus, this is the correct choice.
Answer: (4) The high density of cities leads to an increase in carbon dioxide and global warming.
