According to paragraph 2, what is problematic about an animal's sending visual signals to members of its own species?

• Signs that make an animal visible to its species also make it visible to predators.
• An animal that changes color to avoid predators can confuse members of its species.
• Changing light may require an animal to move beyond the visual range of other members.
• The animal may mistakenly signal aggression when it meant to signal readiness to mate.

This is a multiple choice.
