Reading Passage Question
The Montreal Protocol on Substances that Deplete the Ozone Layer, signed in 1987 by more than 150 nations, has attained its short-term goals: it has decreased the rate of increase in amounts of most ozone-depleting chemicals reaching the atmosphere and has even reduced the atmospheric levels of some of them. The projection that the ozone layer will substantially recover from ozone depletion by 2050 is based on the assumption that the protocol's regulations will be strictly followed. Yet there is considerable evidence of violations, particularly in the form of the release of ozone-depleting chlorofluorocarbons (CFCs), which are commonly used in the refrigeration, heating, and air-conditioning industries. These violations reflect industry attitudes; for example, in the United States, 48% of respondents in a recent survey of subscribers to Air Conditioning, Heating, and Refrigeration News, an industry trade journal, said that they did not believe that CFCs damage the ozone layer. Moreover, some in the industry apparently do not want to pay for CFC substitutes, which can run five times the cost of CFCs. Consequently, a black market in imported illicit CFCs has grown. Estimates of the contraband CFC trade range from 10,000 to 22,000 tons a year, with most of the CFCs originating in India and China, whose agreements under the Protocol still allow them to produce CFCs. In fact, the United States Customs Service reports that CFC-12 is a contraband problem second only to illicit drugs.

Solution and Explanation

  1. The passage suggests which of the following about the illicit trade in CFCs?

(A) It would cease if manufacturers in India and China stopped producing CFCs.
(B) Most people who participate in such trade do not believe that CFCs deplete the ozone layer.
(C) It will probably surpass illicit drugs as the largest contraband problem faced by the United States Customs Service.
(D) It is fostered by people who do not want to pay the price of CFC substitutes.
(E) It has grown primarily because of the expansion of the refrigeration, heating, and air-conditioning industries in foreign countries.

Answer: D
Explanation: The 1996 passage claims that since 1987. The rate of rise in the levels of the majority of ozone-depleting substances reaching the atmosphere has decreased. According to the passage, an illegal market is less expensive. CFCs have developed since certain members of the industry seem unwilling to pay the price of CFC alternatives. This suggests that the members of the industry who are hesitant to pay the higher price of CFC alternatives are at least somewhat responsible for fostering the illicit market.

  1. According to the passage, which of the following best describes most ozone-depleting chemicals in 1996 as compared to those in 1987?

(A) The levels of such chemicals in the atmosphere had decreased.
(B) The number of such chemicals that reached the atmosphere had declined.
(C) The amounts of such chemicals released had increased but the amounts that reached the atmosphere had decreased.
(D) The rate of increase in amounts of such chemicals reaching the atmosphere has decreased.
(E) The rate at which such chemicals were being reduced in the atmosphere had slowed.

Answer: D
Explanation: The passage claims that a clandestine market for less expensive CFCs has developed. Because some members of the industry are unwilling to pay the price of CFC alternatives. This suggests that the members of the industry who are hesitant to pay the higher price of CFC alternatives are at least somewhat responsible for fostering the illicit market. As stated, “The Montreal Protocol on Substances that Deplete the Ozone Layer, signed in 1987 by more than 150 nations, has attained its short-term goals: it has decreased the rate of increase in amounts of most ozone-depleting chemicals reaching the atmosphere and has even reduced the atmospheric levels of some of them.”

  1. The author of the passage compares the smuggling of CFC’s to the illicit drug trade most likely for which of the following reasons?

(A) To qualify a previous claim
(B) To emphasize the extent of a problem
(C) To provide an explanation for an earlier assertion
(D) To suggest that the illicit CFC trade, like the illicit drug trade, will continue to increase
(E) To suggest that the consequences of a relatively little-known problem are as serious as those of a well-known one

Answer: B
Explanation: To illustrate the severity of the CFC-12 problem, the author ranks CFC-12 contraband problems. The term "only after" makes clear how serious and widespread the issue is. To highlight the scale of the illegal CFC trade, the author draws attention to the enormous amounts of CFCs. Hence, B is the right response.
