When a GMAT question says
"if true", you
MUST accept the answer choice as a fact - even if it seems strange. Your job isn't to fact-check whether the answer choice is realistic; your job is to evaluate its
logical impact on the argument.
Think of it this way: Cocoa Grove hosts spring break events. Different universities have breaks at different times, so the "spring break season" for this beach town could easily span
4 weeks as waves of students from different schools arrive throughout March.
The real question is: IF
90% of deaths happen during this
4-week window, does that confirm students are causing them?
Absolutely yes! If alcohol-related deaths spike
exactly when students are present and drop when they leave, that's powerful evidence linking the deaths directly to the student influx.
Common trap: Rejecting answer choices because they seem "unrealistic" based on outside knowledge.
Key Takeaway: Never reject a GMAT answer choice because it seems unrealistic. Accept it as true,
then ask:
"Does this strengthen or weaken the argument?"Answer: D
