The correct answer is (B).
(B) Point at Issue
Step 1: Identify the Question Type
The correct answer will be what two speakers, Edgar and Rafaela, "disagree over," making this a Point at Issue question.
Step 2: Untangle the Stimulus
Edgar argues that it's absurd to shut down some of the regional pumps. He claims the shutdown is all about saving one species of fish, but that's not worth inconveniencing thousands of people. Rafaela, however, argues there's another purpose to shutting down the pumps. If the fish are threatened, then so is the water supply. The fish are merely an indicator of a larger problem.
Step 3: Make a Prediction
Edgar and Rafaela surely disagree about shutting down the pumps. Edgar argues that they should not be shut down, but Rafaela is suggesting that they should be shut down. However, this disagreement stems from a bigger issue. Edgar believes the shutdown is all about saving the fish. Rafaela believes there's more to the shutdown than just one fish species. The correct answer will address the conflicting view on shutting down the pumps or the conflicting view on the motive for shutting down the pumps.
Step 4: Evaluate the Answer Choices
(B) is correct. Edgar would agree with this, saying the pumps are being shut down solely to save the fish. Rafaela would disagree, arguing that there's a greater purpose that involves protecting the water supply.
(A) is not supported. Edgar agrees that people will be inconvenienced, but Rafaela does not dispute that claim. Rafaela only weighs in on the reason why such drastic measures are being taken.
(C) is not supported. Edgar agrees that these specific small fish are inconsequential, but Rafaela does not dispute that. Instead, Rafaela merely emphasizes a greater motive behind the shutdown.
(D) is not supported. Neither speaker addresses the legality of shutting down the pipes.
(E) is not supported. Neither Edgar nor Rafaela address whether the fish will actually be saved or not. The debate is over whether or not the fish are the primary motivation for shutting down the pumps.
