Passage Summary: Even though a bunch of new apartments were built in town, the cost of renting the old ones surprisingly increased.

Reasoning: The supply of housing in Brewsterville increased, which usually lowers rent, yet the rent for existing apartments actually went up.

Analysis: This stimulus presents a situation that defies basic economic expectations of supply and demand. To resolve this discrepancy, we need a piece of information that explains why the price rose despite the increased supply. Perhaps the new apartments were so high-end that they increased the overall desirability of the area, or maybe there was a massive influx of new residents that far outpaced the new construction. We need a factor that counteracts the downward pressure on prices usually caused by new supply.
