Passage Summary: If living downtown gets cheaper, more people move there; if more people move there, business profits go up; but profits only go up if traffic gets better.

Reasoning: The passage establishes a chain of conditional relationships: (Decrease Cost -> Increase Consumers -> Increase Profits) and (Increase Profits -> Decrease Traffic).

Analysis: This stimulus is a logic puzzle built on conditional 'if/then' statements. We can chain them together: Lower Cost → More Consumers → Higher Profits → Less Traffic. Because these are presented as certainties, we can conclude that if the first thing happens, the last thing must also happen. Similarly, if the last thing (less traffic) doesn't happen, then the first thing (lower cost) couldn't have happened. Look for an answer choice that correctly follows this chain or its contrapositive without introducing any outside 'maybes' or 'sometimes.'
