waiting to be fed at the aquarium door catching food using its arms being more active at night hiding behind rocks
I gave my students this multiple choice question: Students visit an aquarium and watch how an octopus behaves in its tank. Which behavior did the octopus most likely learn from its aquarium environment?

Only one answer is correct among these 4 choices:
- waiting to be fed at the aquarium door
- catching food using its arms
- being more active at night
- hiding behind rocks

Could you tell me which one is correct?
