The statement that best explains the results is:
The horseshoes have the same mass, but Drew threw with more force than Blake.
This is because Drew's horseshoe landed past the target, indicating that he threw it with enough force to surpass the target, while Blake's horseshoe only reached three-fourths of the way to the target, suggesting he threw it with less force. The mass of the horseshoes does not appear to be a factor in the results.
