All of these experiments would test the boy's hypothesis.

 

 

30.

A boy observes a robin outside of his window.  He notices the robin repeatedly cocks its head to one side before pecking the ground.  The boy suspects that when the robin cocks its head it is actually listening for worms or insects underground.  If the boy notes that a single robin routinely catches a worm after cocking its head, would this observation prove his hypothesis to be correct?

No, as this is only a single observation.

Yes, and no further experiments are needed.

 

C)

Yes, but further experiments are needed.

theory of evolution.
