Answer:
Sensitive
Step-by-step explanation:
As indicated in the excerpt, Valerie was a strong-willed woman who stood her ground on matters. So, it was a bit surprising when she became teary as a result of Steven's words. She became sensitive or delicate instead of tough and unmoved which was how she was normally known to be.
A sensitive person easily responds to other's actions. In other words, they are delicate. That was the same attitude portrayed by Valerie in this excerpt.
