Best choices:
- Different firefly species have unique light patterns that they flash.
- Fireflies create bursts of light only at night when it is dark.
Why: species‑specific flash patterns imply encoded information (like species ID or mating signals), and emitting flashes when visual detection is possible (darkness) is consistent with a signaling function. The pheromone fact points to chemical communication (not direct evidence that light is used), and the low‑heat property describes mechanism/efficiency rather than demonstrating a communicative role.
