Solution

The statement that best explains how sound is produced by a stringed instrument is: "The vibration of the strings causes the air surrounding the instrument to vibrate."

Here's the step-by-step explanation:

  1. When a string of a stringed instrument (like a guitar or violin) is plucked or bowed, it starts to vibrate back and forth.

  2. This vibration of the string sets the surrounding air molecules into motion, creating pressure waves in the air.

  3. These pressure waves travel away from the string as sound waves.

  4. When these sound waves reach our ears, they cause our eardrums to vibrate. These vibrations are then converted into electrical signals by the inner ear and sent to the brain, which interprets them as sound.

So, the sound from a stringed instrument is produced by the vibration of its strings, which causes the surrounding air to vibrate and produce sound waves.
