Answer:
The next step is to examine why these items on your list affect you the way they do. Carefully examine why you put certain events, cultural practices, places or people in the “Positive Influences” list. Did they teach you something? When you think back on these items, do they bring a smile to your face? Do you feel rested? Enabled? Inspired? These are the things that have shaped your positive attitude and your feelings of self-worth.
This is speculation, so please get a second opinion.
I think it's c, because the adults, in this passage, are teaching children how to behave, and therefore a and b are ruled out. d could have possibly been one, but I think that it would not be, because the adults are not explicitly setting clear examples for their children.
Again, you should get a second answer before you answer this.
