the power of music

¹many people think of music as a source of entertainment, while others feel it’s just a tune playing in the background. ²however, active listening of anything from a mozart symphony to a beatles song has an enormous, positive effect on the brain. ³engagement with music can improve memory and focus, especially in children, by stimulating the brain. ⁴it also engages parts of the brain that control our emotions. ⁵when you listen to music, the brain releases dopamine, prolactin, and serotonin, which are chemicals that boost your mood. ⁶as a result, people tend to feel an increase in energy and a decrease in stress levels. ⁷finally, tuning out and turning on your tunes can shift your brain waves from beta to more relaxed alpha and theta states.

Explanation:

First Question:

The paragraph's title is "The Power of Music", and most sentences discuss how music affects the brain, mood, etc. "Music" is the central topic. "Brain" is what music affects, "Entertainment" is a common view of music but not the key focus.

• Sentence 2: "active listening of anything from a Mozart symphony to a Beatles song..." (song is music, so relates to music).
• Sentence 3: "Engagement with music..." directly uses "music".
• Sentence 4: "When you listen to music..." directly uses "music".
• Sentence 5: "As a result..." doesn't repeat "music". So Sentences 2,3,4 repeat the key word.

"Tunes" in "turning on your tunes" refers to music. "Anything" is what's listened to (like symphony, song), not a synonym. "Source" refers to music as a source of entertainment, not a synonym.

Answer:

A. Music
