It just means that you need to write down how your journey with music has made you feel and what it means to you. For the wider social group part it means that have you met new people or connected with other people by liking the same kind of music.

Sample Response:
Dr. King's dream of equality has not been achieved in education. There is still a difference between the number of African Americans who receive high school diplomas and the number of whites who do. According to the US Census Bureau, in 2000, only 72 percent of African Americans had diplomas while about 83 percent of whites did.

Because the groups do not have equal percentages, King's dream of equality has not actually been achieved.
