Question

kirk had a bird feeder hanging from a pole in his backyard. but squirrels kept stealing the birdseed from the feeder and scaring the birds away. kirk wanted to prevent any squirrels from climbing onto his feeder. so, he put a loose metal spring around the pole to make it harder for squirrels to climb. then, every morning for a week, he observed whether any squirrels got to the bird feeder.
which of the following could kirk’s test show?
how often squirrels stole food from a bird feeder on a pole throughout the day
whether squirrels visited a bird feeder more often if it was hanging from a tree or from a pole
whether squirrels stole food from a bird feeder on a pole with a metal spring around it

Explanation:

Kirk's test involves observing squirrels' access to the bird feeder after adding a metal spring to the pole. The first option is about daily frequency (he observed mornings), the second about tree vs pole (he only used a pole). The third option matches his test: checking if squirrels steal food with the metal spring.

Answer:

whether squirrels stole food from a bird feeder on a pole with a metal spring around it
