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.

there are two central themes in  the miracle worker: that the human spirit can triumph over even the most daunting of disabilities and that a dedicated teacher can transform the lives of those with whom he or she comes into contact. these inspirational themes have long been personified in the widely known true-life relationship between helen keller and annie sullivan, but  the miracle worker  also dramatizes collateral issues that extend beyond the particular case. underlying helen’s process of learning basic principles of what annie terms “obedience” (decorum, etiquette, and hygiene), there are more universal lessons of self-governance—the inculcation of self-restraint instead of willfulness, the development of self-discipline instead of self-indulgence. only when these lessons have been mastered can helen begin to acquire language—which, annie says, “is to the mind more than light is to the eye.”
