In the last ten years, usage of pay phones in Bridgeport has dropped by 90%.Since cell phone usage is much higher among middle- and upper income residents of Bridgeport than among lower-income residents, the Bridgeport City Council has decided to remove pay phones from middle- and upper-income neighborhoods, while retaining those in lower-income neighborhoods, reasoning that this plan will respond appropriately to demand for pay phones and therebyinconvenience very few people.
Which of the following would be most helpful to know in order to evaluate the reasoning of the City Council? (A) Whether pay phones are used by criminals conducting drug deals (B) A comparison of pay phone usage between middle income and high in come residents (C) How many low-income residents use cell phones (D) Whether low-income residents typically use pay phones close to home (E) Whether eliminating pay phones would lose revenue for the city 正确答案是(D)
FOV对答案C的解释是:Note that (C) wouldn’t help the argument at all, since you don’t know what the relationship is between cell phone usage and pay phone usage. You can’t FIX an assumption by making additional assumptions(such as that more cell usage means less pay phone usage). 这个解释没看懂,求NN解答,感谢!
