Why save endangered species? For the general public, endangered specie

Question

Why save endangered species? For the general public, endangered species appear to be little more than biological oddities. A very different perception is gained from considering the issue of extinction in a wider context. The important point is that many major social advances have been made on the basis of life forms whose worth would never have been perceived in advance. Consider the impact of rubber-producing plants on contemporary life and industry: approximately two-thirds of the world's rubber supply comes from rubber-producing plants and is made into objects as diverse as rubber washers and rubber boots.   1

2. All of the following facts could be used as illustrative examples in addition to the example of rubber-producing plants EXCEPT:

Explanation

The passage uses the example of rubber-producing plants to show how species that seem insignificant can have major impacts. For this question, we need to find the choice that does not align with this theme of unexpected or indirect value derived from natural sources.

(A)  is an example of a virus leading to the discovery of a vaccine, fitting the pattern of unexpected benefit from natural observations.

(B)  fits because it describes medicinal value derived from plants, paralleling the rubber example.

(C)  fits as it describes antibiotics derived from mold, another natural source leading to significant advances.

(D)  does  not  fit because plastic is derived from petroleum, which is not a natural life form like the other examples; this disrupts the pattern.

(E)  fits as it discusses rodents being useful in medical testing, an unexpected benefit from a natural species.

Answer: (D)

1. The author's point is made chiefly by

Explanation

The passage begins by addressing the general perception of endangered species as merely biological oddities. It then shifts to a broader context, emphasizing the importance of these species in relation to major social advances and industries, specifically highlighting rubber-producing plants. By framing the discussion in this way, the author suggests a new perspective: that the value of endangered species extends beyond their immediate appearance and can have significant, unforeseen benefits.

(A)  is incorrect because the passage does not acknowledge opposing viewpoints; it focuses on advocating for a broader perspective.

(B)  is incorrect because the passage relies on factual examples rather than emotional appeals.

(D)  is incorrect because the author is not discrediting an opponent’s view but rather expanding the understanding of the value of endangered species.

(E)  is incorrect because the passage does not generalize from similar to dissimilar cases; it instead provides a specific example to illustrate its point.
