Hi Punyata
Welcome to gmat club
I'm glad to help.
ANALYZE THE STIMULUS:Mel: The official salary for judges has always been too low to attract the best Candidates
[potential candidates] to the job. The legislature’s move to raise the salary has done nothing to improve the situation, because it was coupled with a ban on receiving money for lectures and teaching engagements.
Pat: No, the raise in salary really does improve the situation. Since very few judges
[current members] teach or give lectures, the ban will have little or no negative effect
Pat’s response to Mel is inadequate in that it
ANALYZE EACH ANSWER:A. attempts to assess how a certain change will affect potential members of a group by providing evidence about its effect on the current members.
Correct. Mel talks about potential candidates, however Pat talks about current members
B. mistakenly takes the cause of a certain change to be an effect of that change
Wrong. The argument does NOT talk about the cause of a change (the legislature’s move to raise the salary).
C. attempts to argue that a certain change will have a positive effect merely by pointing to the absence of negative effects
Wrong. Pat just says the ban will have little or no negative effect. He does NOT talk anything about positive effect.
D. simply denies Mel’s claim without putting forward any evidence in support of that denial
Wrong. TEMPTING but wrong. Pat denies Mel’s claim WITH evidence in support. However, his evidence has problem itself.
E. assumes that changes that benefit the most able members of a group necessarily benefit all members of that group.
Wrong. TEMPTING but wrong. Pat said the change does
NOT hurt (will have little or no negative effect) the current member. He did
NOT say the change BENEFITS the current member. These logics are totally different..
For example: The new shopping outlet does not have negative effect to shopping malls in downtown. ==> It does not mean the new shopping outlet has positive effect to shopping malls in downtown.
TAKE AWAY:Be aware of reverse logics
A does NOT hurt B ==> does not mean A supports B
A does NOT support B ==> does not mean A hurts BHope it helps.
