Answer: BThe correct answer is (B) Between 1988 and 1992, Sunnyville's leading political party revised its platform, adopting the policies of the Alternative Energy Action party.
Explanation:The argument concludes that alternative energy concerns faded in significance based on the Alternative Energy Action party losing seats. Option B weakens this conclusion by providing an alternative explanation: voters still cared about alternative energy, but now they could support these policies through the leading party instead. This suggests that support for alternative energy policies may have remained strong or even increased, despite the Alternative Energy Action party's electoral defeat.
Why each other option is incorrect:(A) Information about the percentage of eligible voters who voted doesn't address whether alternative energy concerns specifically faded in significance. This is irrelevant to the relationship between the party's loss and public interest in alternative energy.
(C) The fact that the same parties ran candidates in both elections doesn't explain why the Alternative Energy Action party lost seats or whether alternative energy concerns faded in significance.
(D) This actually strengthens rather than weakens the argument by confirming that the party received fewer votes, which aligns with the conclusion that alternative energy concerns faded.
(E) While this suggests some progress on alternative energy initiatives, the "inconclusive results" don't explain why voters would have abandoned the Alternative Energy Action party if they still cared about these issues. This doesn't provide a clear alternative explanation for the party's defeat.
