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

A) sound and vibrations travel faster through gases than solids.

B) sound and vibrations travel faster through solids than gases.

C) sound and vibrations dissipate faster in solids than in liquids or gases.

D) sound and vibrations are more concentrated in solids than in liquids or gases.

D would be the probable answer. A makes no sense because the cowboy is listening to a solid. B makes some sense because the particles in solids are close together, making the vibrations travel quickly. C does not make sense because if the vibration dissipated, then it would not be felt. D is most likely the correct answer because it is easier to feel more concentrated vibrations.
