Solution:
To find the correct answer to this specific purpose question, we first locate “the cost of deterioration of nature” in the passage.
Scanning the passage, we see that “the cost of deterioration of nature” is mentioned at the very end of the passage. So, to understand the purpose of mentioning “the cost of deterioration of nature,” we’ll reread the sentences that precede it for context.
Looking at what immediately precedes “the cost of deterioration of nature” we see “negatives associated with economic growth, such as loss of leisure time and the cost of deterioration of nature.” So, the sentence uses “such as” to indicate that “the cost of deterioration of nature” is an example of “negatives associated with economic growth.”
Now, looking at more of the sentence, we see that it says, “GPI … differs from GDP mainly in that it is based on not only information on aggregate production but also information on negatives associated with economic growth, such as loss of leisure time and the cost of deterioration of nature ….” So, the passage indicates that “information on negatives associated with economic growth” is something that GPI is based on, and GDP is not based on.
So, the author mentions “the cost of deterioration of nature” to provide an example of “negatives associated with economic growth” that GPI is based on, and GDP is not based on.
(A) provide an example of why the use of GDP ought to be discontinued
This choice starts off correctly because, as we discussed in the introduction to this explanation, the author mentions “the cost of deterioration of nature” to “provide an example.”
However, this choice goes wrong partway through because, in the sentence in which “the cost of deterioration of nature is mentioned, the author does not argue that “the use of GDP ought to be discontinued.” The sentence is purely descriptive, presenting ways in which GPI differs from GDP.
This choice is a good example of why we’ll get best results by reading choices in their entirety.
(B) recommend that nations make the preservation of nature a higher priority
We can quickly see that this choice is incorrect by reviewing the sentence that mentions “the cost of deterioration of nature,” S8.
In doing so, we see that the verb “recommend” in this choice does not accurately describe any aspect of that sentence. After all, in S8, the author does not “recommend” that nations do anything. Rather S8 is entirely descriptive, presenting how GPI differs from GDP.
(C) show the importance of using additional information beyond aggregate production to measure national development and progress
We can see that this choice is incorrect by reviewing the sentence that mentions “the cost of deterioration of nature,” S8.
In doing so, we see that the author does not mention “the cost of deterioration of nature” to “show” (demonstrate or prove) anything. Rather, the author says, “such as … the cost of deterioration of nature” to provide an example of “negatives associated with economic growth.”
(D) argue that GPI should be used instead of GDP
We can see that this choice is incorrect by reviewing the sentence that mentions “the cost of deterioration of nature,” S8.
In doing so, we see that the verb “argue” in this choice does not accurately describe any aspect of that sentence. After all, in S8, the author does not “argue” anything. Rather S8 is entirely descriptive, presenting how GPI differs from GDP.
CORRECT ANSWER(E) cite a specific effect that GDP does not take into account
As we discussed in the introduction to this explanation, the author mentions “the cost of deterioration of nature” to provide an example of “negatives associated with economic growth” that GPI is based on, and GDP is not based on.
Since “cite a specific effect that GDP does not take into account” is another way of saying “provide an example of ‘negatives associated with economic growth’ that … GDP is not based on,” we can see that this choice correctly describes the author’s purpose in mentioning “the cost of deterioration of nature.”
