Neuroscientists have suggested that playing an instrument, especially at an early age, can improve how the brain interprets sensory information. Music (singing or playing an instrument) also positively affects memory. Apparently, music activates both the right and left sides of the brain simultaneously and this activity increases efficiency in processing information. In one study, researchers found the areas of the brain that affect language skill and “executive function” were more developed in musically trained students. The executive function is the planning center of your brain, where you figure out what must get done, and how to do it in the time that exists. What is the central idea of Paragraph 5 in this passage?

A: Students who study music have better-developed language skills and executive function.

B: The executive function in the brain determines what must get done and the time it will take.

C: Music activates the right and left sides of the brain simultaneously.

D: Playing an instrument while a child is still young is essential.
