听力原文：Hello, my name is Jennifer White, and I will be your tour guide here at this 13th-century fort. If you have any questions or comments, please feel free to ask me and I will be more than happy to answer. We are now at the famous gateway leading to the fort. This leads to the grand pavilion at the top that served as a royal court. Clap your hands under the dome here and people can hear you more than a mile away! The pipes there on the hillside were part of an efficient water supply system that carried water from the lake below to the fort's residents. We'll now see a special show that relates some of the major events that occurred here. Who is this talk for?
