Answer:
It is trying to ask "What dominant (biggest or strongest) trait is causing more problems."
A dominant trait is the trait that is a big part of who you are and affects your life heavily.
So think of the most dominant trait the main character has, and reflect on how much it affects their life and/or makes it hard for them.
