Mayor Smith, one of our few government officials with a record of outspoken, informed, and consistent opposition to nuclear power plant construction projects, has now declared herself in favor of building the nuclear power plant at Littletown. If someone with her past antinuclear record now favors building this power plant, then there is good reason to believe that it will be safe and therefore should be built.
The argument is vulnerable to criticism on which one of the following grounds?
(A) It overlooks the possibility that
not all those who fail to speak out on issues of nuclear power are necessarily opposed to it. - WRONG. Not concerned about all.
(B) It assumes without warrant that the qualities enabling a person to be elected to public office
confer on that person a grasp of the scientific principles on which technical decisions are based. - WRONG. Being technically versed is not necessary.
(C) It fails to establish that a consistent and outspoken opposition is
necessarily an informed opposition. - WRONG. Informed and consistent and outspoken are independent of each other.
(D) It leads to the further but unacceptable conclusion that any project favored by Mayor Smith should be sanctioned simply on the basis of her having spoken out in favor of it. - WRONG. Yes, that is what which is questionable. But this choice only rephrases what is already stated in the passage.
(E) It gives no indication of either the basis of Mayor Smith’s former opposition to nuclear power plant construction or the reasons for her support for the Littletown project. - CORRECT. Why the conclusion just as it is or why she earlier was like that on the same issue? We have no answer.
Answer E.
