Hi

I have a specific question for PT 58 Q12 City Councilperson: Many City Residents.

for answer choice A, don't we negate sufficient after unless?

I understand why A is the incorrect answer choice because of "causes" when we need it to say "Purpose". But many preptest websites in their explanation do not negate ~causes debate-->~qualifies as art For answer choice A. Would you be able to explain if we ought to negate, sufficient for answer choice A? thank you
