Nutritionists are advising people to eat more fish, since the omega-3 fatty acids in fish help combat many diseases. If everyone took this advice, however, there would not be enough fish in oceans, rivers, and lakes to supply the demand; the oceans are already being overfished. The obvious method to ease the pressure on wild fish populations is for people to increase their consumption of farmed fish.
Which of the following, if true, raises the most serious doubt concerning the prospects for success of the solution proposed above?
选项
A、Aquaculture, or fish farming, raises more fish in a given volume of water than are generally present in the wild.
B、Some fish farming, particularly of shrimp and other shellfish, takes place in enclosures in the ocean.
C、There are large expanses of ocean waters that do not contain enough nutrients to support substantial fish populations.
D、The feed for farmed ocean fish is largely made from small wild-caught fish, including the young of many popular food species.
E、Some of the species that are now farmed extensively were not commonly eaten when they were only available in the wild.
答案
D
解析
Argument Evaluation
Situation Nutritionists advise people to eat fish for the omega-3 fatty acids, but there would not be enough fish to meet the demand if everyone followed this advice. Therefore, people should increase the r consumption of farmed fish to ease pressure of wild fish populations.
Reasoning What evidence would suggest that increasing consumption of farmed fish would not ease pressure on wild fish populations? Any evidence suggesting that significantly increasing consumption of farmed fish would diminish the habitat or food available for wild fish would also suggest that increasing consumption of farmed fish would not ease pressure on wild fish populations.
A Probably the less space fish farming requires, the less pressure it creates on wild fish habitats and populations, other things being equal.
B Whether any fish farming takes place in enclosures in the ocean is not clearly relevant to whether it eas es pressure on wild fish populations.
C Substantial fish populations may thrive in other large expanses of ocean water that contain more nutrients, and in rivers and lakes.
D Correct. This suggests that increasing consumption of farmed fish would require increased use of wild fish as feed for farmed fish and therefore would not ease pressure on wild fish populations.
E Even if some farmed fish are different species from the wild fish that are commonly eaten, increased consumption of the farmed fish could reduce demand for the wild fish and thereby ease pressure on wild fish populations.
The correct answer is D.
