Answer:
primary waves pass through the outer core but shear waves do not.
Explanation:
The evidence which best supports the inference that the Earth's outer core possesses liquid characteristics is that, primary waves pass through the outer core but shear waves do not.
This ultimately implies that, the Earth's outer core possesses liquid characteristics because it allows primary waves only to pass through but not shear waves.
