Paragraph 5 refines the ideas about brain research in paragraph 3 by <em>giving more precise examples of how musical training can change the brain.</em> <u>The correct answer is the second one.</u>
Explanation:
The third paragraph <u>explains with more general ideas</u> how studying music can be beneficial for people, and adds that the younger you are, the more your brain can develop if you are trained in music. The fifth paragraph is a much more specific; it says that neuroscientists suggested that playing an instrument "<em>can improve how the brain interprets sensory information</em>". As we can see in this last line, the information about how can a brain improve its development by studying music is much more specific. Also, this paragraph says that: "<em>music activates both the right and left sides of the brain simultaneously and this activity increases efficiency in processing information.</em>" The third paragraph functions as an introduction of the theme, despite not being the first paragraph, and the fifth one <u>gives more precise information with examples and with professional evidence.</u> That is why the second one is the correct answer.
