Passage: Music profoundly influences both emotions and the physical state. Up-tempo rhythms can heighten alertness and sharpen attention, while cheerful melodies often elevate mood and foster optimism. In contrast, slower compositions help the mind relax, ease muscular tension, and offer a sense of restoration after a demanding day. Due to these effects, music is often used as a strategy for stress relief and mental rejuvenation. Studies support these observations. Music with a gentle, steady rhythm can guide the brain into relaxation, promoting mental balance and emotional stability. Immersion in pleasant or rich melodies in a comfortable environment can even prepare the mind for restful recovery. Research shows that music can modulate neural activity and enhance cognitive and emotional functioning, thereby offering a natural means of managing stress. Certain auditory experiences are especially effective. Instrumental compositions, rhythmic drumming, flutes, or blends of music with natural sounds such as rainfall or flowing streams can be refreshing and restorative. Light jazz, classical slow movements, or mellow tunes often help listeners achieve peace of mind. The key is to choose music that resonates personally, as forcing oneself to listen to harsh or unpleasant sounds may increase tension rather than relieve it. Question: Which of the following is a fact mentioned in the passage?

1. Only classical music can relieve stress.
2. Up-tempo rhythms reduce alertness.
3. Music can guide the brain into relaxation.
4. Listening to music is harmful to focus.
