Question
In the old west, a cowboy would put their ear on the railroad track to determine if a train was coming. Using this method, they could tell if the train was coming sooner than just listening for the train.
A good explanation for this would be that

The correct explanation for why a cowboy could determine if a train was coming by putting their ear on the railroad track is:
**B** sound and vibrations travel faster through solids than gases.
This is because sound waves travel more efficiently through denser mediums like solids (such as the metal of the railroad tracks) compared to lighter mediums like gases (such as air). Therefore, the vibrations from the approaching train would reach the cowboy more quickly through the track than through the air.
