PrepTest 92+, Section 1, Question 3
When frightened by hunters in a truck, healthy gazelles run away quickly, efficiently using the landscape for concealment. But when a healthy gazelle detects the approach of a predator such as a lion, it leaps high into the air as it runs away—a behavior known as "stotting." As a defensive behavior, stotting appears paradoxical, because it draws predators' attention and consumes energy that could be put into running faster.

Which one of the following would, if true, most help to resolve the apparent paradox described above?
Animals that are startled sometimes act in ways that appear irrational to human observers.
Young gazelles and gazelles that are not very healthy often stot when they become frightened by humans or by loud machines.
To animals that typically prey on gazelles, stotting is a signal of strength and ability to escape.
A healthy gazelle can usually detect the approach of a predator before the predator becomes aware of the presence of the gazelle.
While not able to run as quickly as gazelles, predators such as lions hunt effectively by hunting in groups and coordinating their attacks.
