Which of the following, if true, provides the strongest grounds for a prediction that municipalities will buy QuickFreeze's purification system despite the need to maintain a conventional purification system as well?

      【OG18-P512-558题】Parland's alligator population has been declining in recent years, primarily because of hunting. Alligators prey heavily on a species of freshwater fish that is highly valued as food by Parlanders, who had hoped that the decline in the alligator population would lead to an increase in the numbers of these fish available for human consumption. Yet the population of this fish species has also declined, even though the annual number caught for human consumption has not increased.Which of the following, if true, most helps to explain the decline in the population of the fish species?

    Shirla: In figure skating competitions that allow amateur and professional skaters to  compete against each other, the professionals are bound to have an unfair advantage. After all,  most of them became professional only after success on the amateur circuit. Ron: But that means that it’s been a long time since they’ve had to meet the more rigorous  technical standards of the amateur circuit.

    Researchers in City X recently discovered low levels of several pharmaceutical drugs in  public drinking water supplies. However, the researchers argued that the drugs in the water  were not a significant public health hazard. They pointed out that the drug levels were so low  that they could only be detected with the most recent technology, which suggested that the  drugs may have already been present in the drinking water for decades, even though they have  never had any discernible health effects. Which of the following, if true, would most strengthen the researchers’ reasoning?

    City resident: These new digital electronic billboards should be banned for light pollution  since they are much too bright. Outdoor advertising spokesperson: No, that’s not true. Testing with a sophisticated light meter  shows that at night they throw off less light than traditional billboards that are reflectively lit.  Your mistaken perception that they are brighter comes from looking directly at the light  source—the screen itself. The underlying strategy of the spokesperson’s response to the resident is most analogous to the  underlying strategy of which of the following?
