Passage Summary: Grizzly bears eat a ton of lilies, which seems like it would wipe them out, but scientists say the bears actually help the lilies thrive.

Reasoning: Bears eat the bulbs of iceberg lilies, which destroys the individual plants, yet this behavior is somehow beneficial to the lily population's overall survival.

Analysis: The paradox here is the contradiction between 'destroying a large percentage' of the plants and 'promoting survival.' To resolve this, we need a bridge that explains how the destruction of some plants helps the species as a whole. Perhaps the bears' digging helps the remaining lilies grow better, or maybe they inadvertently help the plants reproduce. Look for an answer that provides a hidden benefit to the bears' destructive behavior.
