Who most likely is the speaker? [originaltext]Before we enter the zoo, I want to

Before we enter the zoo, I want to go over the rules. You are not to feed the animals, and if you are eating something, please make sure you are not close to a pen. Many animals have a very good sense of smell, and they might not leave you alone. Please stay with your partner, and try to stay close to the group. As I am speaking on the tour, feel free to interrupt me to ask questions. Simply raise your hand, and I’ll be happy to let you speak. The zoo is quite large, so I’ve made a map of everything. In case anyone gets lost, we will be meeting outside of the aquarium after lunch. The schedule is written on the back of the map. Now, let’s head to the zoo. Please hand your tickets to me as you get off the bus.
