What does "quicker" modify?

Hi~ In the part underlined, what do you think the word "quicker" modify?

Avoided quicker and ... internalized quicker?

OR just internalized quicker?

Thanks for sharing your idea~

The second conclusion that should be drawn is that school discipline
needs to focus on the demonstration of what it is that the adults expect
students to do rather than verbal directives.

By adopting a discipline model that demonstrates desired
behaviors, some incidents will be avoided and desired practices will be
internalized quicker.
