Directions: Read the following passage and answer the question that follows.

Bini Aru had used this secret many times, but not to cause evil or suffering to others. When he had wandered far from home and was hungry, he would say: "I want to become a cow — Pyrzqxgl!" In an instant, he would be a cow, and then he would eat grass and satisfy his hunger. All beasts and birds can talk in the Land of Oz, so when the cow was no longer hungry, it would say: "I want to be Bini Aru again: Pyrzqxgl!" and the magic word, properly pronounced, would instantly restore him to his proper form.

What was the special thing all beasts and birds were able to do in the Land of Oz?
