Hello. You did not show the text to which this question refers, which makes it impossible for it to be answered accurately, however, I will try to help you in the best possible way.
To explain the connection between peaceful protest and positive change, a text must show that peaceful protest requires social and political changes to be made, through a request that does not demonstrate violence or civil disobedience, whereas positive change causes these changes in society in a non-violent and peaceful way.
