13. Previously it was suggested that the brain __ different sources of sound by analysing which direction they come from. A) confuses B) vanishes C) dis appears D) distinguishes E) varies

The correct answer is D) distinguishes.<br /><br />The brain distinguishes different sources of sound by analyzing which direction they come from. This process is known as sound localization. The brain uses various cues, such as the time difference between when a sound reaches each ear and the difference in loudness between the two ears, to determine the direction of the sound source. This allows us to identify the location of sounds in our environment.
