Final answer:
When one cow gets spooked, the rest of the herd is likely to become agitated and show similar behavior.
Step-by-step explanation:
Annie is herding cattle when one of them gets spooked. The likely reaction of the herd is that they will all become agitated. When one cow gets frightened, it can cause a chain reaction in the herd, as cows are highly social animals. They tend to mimic the behavior of the rest of the herd, so if one cow becomes agitated, the others are likely to follow suit.
