In Sunnyville the new Alternative Energy Action party won two seats on the seven-member town council in 1988, it lost both of those seats in the 1992 election; even though the party’s pro- alternative energy platform had essentially remained unchanged. This decline in the party’s fortunes clearly demonstrates that, in Sunnyville, alternative energy concerns faded in significance between 1988 and 1992.
Which of the following, if true, most seriously weakens the argument?
(A) Between 1998 and 1992, the number of eligible voters in Sunnyville rose, but not the percentage who actually voted.
(B) Between 1988 and 1992, Sunnyville’s leading political party revised its platform, adopting the policies of the Alternative Energy Action party
(C) The parties that ran candidates in the 1992 election in Sunnyville were the same as those that had done so in the 1988 election.
(D) In 1992 the Alternative Energy Action party won fewer votes in Sunnyville than it had won in 1988.
(E) Between 1988 and 1992, some measures intended to provide alternative energy had been adopted by the town council, but with inconclusive results
OFFICIAL EXPLANATION:
On the basis of the information that the new Alternative Energy Party, which had won 2 seats out of 7 in the town council in 1988, had lost both of them in 1992, the author argues that the decline in the party’s fortunes clearly demonstrates that alternative energy concerns faded in significance in the town during this period.
We have been asked to locate that choice which most seriously weakens this argument.
(A) merely says that both the number of voters and the number who voted increased between 1988 and 1992, but does not give a reason which strengthens or weakens the author’s theory why the Alternative Energy Action Party lost its seats.
(B) says that the town’s leading political party (which had won the majority of the other 5 seats in 1988) had revised its platform adopting a strong alternative energy stance. If this is true, voters who are in favor of alternative energy might have voted for the leading political party itself this time instead of for the Alternative Energy Action party. So, the defeat of the members of the Alternative Energy party would not mean that the environmental concerns had faded in significance in the minds of the voters. On the contrary; the reason why the dominant party adopted a strong alternative energy stance may itself be because the public concern for alternative energy had become more intense, and the dominant party wanted to go along with that popular sentiment. So, it is (B) which seriously weakens the argument of the author, and is the answer.(C) neither strengthens nor weakens the argument, and is not the answer.
(D) strengthens the argument of the author, and does not weaken it.
(E) would give a reason why the voters could have been disillusioned with the Alternative Energy Action party, because of which environmental concerns could have faded in significance. So, (E) strengthens the argument of the author, and does not weaken it.
