Passage Summary: A town that recently needed help itself just gave a massive amount of aid to another town facing a similar disaster, even more than they gave to a different kind of disaster in the past.

Reasoning: Hollyville residents provided significantly more aid to a fellow river town facing a flood than they did to earthquake victims years prior, following a year where Hollyville itself was a victim of a disaster.

Analysis: This stimulus presents a set of facts that suggest a pattern of behavior. We are looking for a principle that explains why Hollyville was so much more generous toward the river town than the earthquake victims. The most likely connection is the similarity of the disaster or the town's recent experience as a recipient of aid. It seems that having 'walked a mile' in the victims' shoes—or at least living in a similar pair of shoes—makes people more likely to open their wallets.
